Fiberstrong & Wavistrong Flange GuideFiberstrong & Wavistrong Flange Guide4

1. General

This Flange Guide describes the requirements, needs and methods for the installation of Fiberstrong and Wavistrong fibre-reinforced plastic (FRP) flanges. To ensure proper installation of FRP flanges, information, guidelines and instructions on drilling dimensions, sealing material, bellows, spacer rings, flange supports, fasteners and flange assembly are given.

A flanged joint can consist of any combination containing a fixed flange, a stub-end flange or a blind flange. In this document, fixed flange, stub-end flange and blind flange will be referred to as “flange”.

The Fiberstrong and Wavistrong flange design for fixed flanges is in line with (i) the design rules for flanged joints as described in ASME 2010 section X and (ii) the flange rigidity criterion as described in ASME 2010 section VIII, division 2.

Definition of words used in these instructions: • The word “shall” indicates a requirement • The word “should” indicates a recommendation

2. Product range and flange types

2.1. Product range

This Flange Guide describes the Fiberstrong as well as the Wavistrong flanges. The standard Fiberstrong flange product range runs from ID 25 to ID 4000 mm and is available in pressure classes PN 4 to PN 16 bar. The standard Wavistrong flange product range runs from ID 25 to ID 1800 mm and is available in pressure classes PN 8 to PN 50 bar. For the Wavistrong product range reference is made to the Wavistrong Product List.

2.2. Flange types

The FPI product range contains various types of flanges, namely fixed flanges, stub-end flanges and blind flanges.

A fixed flange is a flange with an integral hub (see fig. 1). Fiberstrong fixed flanges are produced using either the filament winding (FW) process or the contact moulding process (CM). Wavistrong fixed flanges are available as FW only.

A stub-end flange is an assembly of a FRP stub-end and a loose flange ring. Stub-end flanges are available in two varieties: 1. Stub-end flanges having a cylindrical shaped internal configuration

(see fig. 2), these products are referred to as “stub-end flange CB/FL” and are available for the Wavistrong product range only. The flange ring of those products is available in steel only.

2. Stub-end flanges having a 45 degree conical shaped configuration (see fig 3), these products are referred to as “stub-end flange FL/PL”. The flange ring is available in both FRP and steel.

3. Drilling standards

The product dimensions of Fiberstrong and Wavistrong FRP flanges are defined by, diameter, drilling pattern and pressure class. The pressure rating is defined by the pressure class of the flange. This practice deviates from the method as used for steel flange, where flanges are rated by the applicable drilling class.

Fiberstrong and Wavistrong flanges up to and including ID 600 mm are, depending on the pressure class of the product, available as standard item according drilling standards ASA 150, ASA 300 and PN 10 to PN 63. ASME, AWWA and MSS drilling patterns are described by the ASA drilling pattern.Other drilling standards (API/JIS/etc.) are non standard but are available upon request.

Fiberstrong and Wavistrong flanges ID 700 mm and above are available as standard item for drilling standards ASA 150 and ASA 300. Other drilling standards (API/JIS/PN/etc.) are non standard, but are available upon request.

The drilling patterns of the most common drilling standards are given in Annex H.

Fig. 2. Stub-end flange CB/FL

Fig. 3. Stub-end flange FL/PL



4. Gasket and O-ring seal

Flanges ID 25 – ID 1400 mm should be assembled using FPI recommended type rubber gaskets with steel inlay (see fig. 4): • Kroll & Ziller type G-ST-P/K • Kroll & Ziller type G-ST-P/KN • Kroll & Ziller type G-ST-P/S • Kempchen type WG2

Flanges ID 1500 – 4000 mm, have a grooved face and shall be assembled using a rubber O-ring seal. The O-ring dimensions are given in Annex C.

The sealing material depends on the transported medium and temperature and shall be specified by the gasket or O-ring supplier. The hardness of the gasket sealing material shall be of class 70 or 80 ± 5 Shore A. The hardness of the O-ring material shall be of class 70 ± 5 Shore A.

The use of graphite, spiral wound and metal gaskets is not advised, as these types of gaskets require a high bolt torque which might lead to overloading of the FRP flange.

5. Bellows

Rubber bellows are primarily used to reduce loads and to facilitate removal of pipe sections, valves or gaskets. Bellows are also used to absorb noise and vibration between equipment such as pumps, condensers and their mating pipe work. Their high flexibility also makes them suitable for compensating thermal expansions and small installation misalignments.

Axial and universal bellows are designed to absorb any combination of three basic movements, i.e. axial movement, lateral deflection and angular rotation. These bellows are non-restrained, therefore to absorb axial forces it shall be ensured that the mating pipe systems at both sides of the bellow are fixed.

Lateral bellows (see fig. 5) are designed to absorb lateral deflection. Tie rods shall be used on lateral bellows to transfer the pressure thrust load. Sufficient tie rods shall be used, to prevent local overloading of the FRP flange. Tie rods shall never be jointed directly to the FRP flange or to the FRP piping systems, as this will create excessive axial loads on the FRP flange. The backing flange, which is part of the axial bellow shall be a solid construction, the usage of “fish-plates” is not allowed.

Hinged bellows or gimbal bellows are designed to absorb angular rotation. Hinged and gimbal bellows are due to their construction capable in transferring the axial load, therefore tie rods are not required.

Bolt torque values as specified by bellow suppliers might deviate from the torque values as specified in this document. To prevent overloading of the FRP flange, the torque values specified in chapter 8 shall not be exceeded unless agreed by the FPI Technical Support team.

The maximum deflection specified by the bellow supllier may not be exceeded.UV covers should be installed, to protect the rubber of the outdoors installed bellows.

In order to ensure a proper usage of bellows, their selection shall be reviewed by the FPI Technical Support team.

6. Spacer rings

Fiberstrong and Wavistrong flanges are designed such that these flanges can be jointed against raised face flanges, on the condition that the in chapter 8 prescribed bolt torques are applied. For flanges ID 25 – ID 1400 mm in fact a raised face configuration is created by the usage of a rubber gasket with a steel inlay (see chapter 4). Spacer rings may be used, if FRP flanges are jointed to metallic raised face flanges, in order to create a flat face configuration. Please note that the mating flange might have an uneven surface at the bolt circle. Therefore the thickness of each spacer ring has to be adjusted to it’s specific required dimension.Incorrect spacer ring thickness can result in local overloading of the flange or insufficient gasket seal.

7. Fasteners

This section gives information about the type, the quality, the thread standard and dimensions of fasteners to be used for the assembly of a flanged joint.

7.1. Bolts, stud bolts, washers

Flanges are jointed using either bolts or stud bolts. Stud bolts are typically used in case of assembly in limited spaces, or if long bolt lengths are required. The bolt size’s accompanying washer shall be used (see Annex B for washer dimensions).

7.2. Fastener quality

Bolts, nuts and washers should be either made of hot dip galvanized steel or made of stainless steel. For non corrosive environments zinc plated steel products may be used.The minimum quality of hot dip galvanized and zinc plated steel bolts, nuts and washers should be of class 8.8 or grade 5. The minimum quality of stainless steel fasteners should be of class 70. Figures 6 and 7 show the identification for class 8.8 and for grade 5 bolts. In case hot dip galvanized or zinc plated steel products are cut to length, the cut area should be coated to protect it against corrosion.

7.3. Thread standard

The thread standard of the fasteners shall comply with either ISO metric or Unified Thread Standard (UTS). In case of assembly against a component containing a threaded hole, the bolt size shall match the hole’s thread.Metric and UTS bolts and nuts, shall have a coarse pitch; for UTS this is specified as UNC or NC, for metric this is specified as coarse.

Flanges shall be assembled using the bolt size as specified in Annex H.

Fig. 7. Grade 5 identification on bolt head




7.4. Bolt length

The bolt length definition for two fixed flanges is specified in paragraph 7.4.1 and for two stub-end flanges in paragraph 7.4.2. The same method can be followed for the bolt length definition of any flange combination, such as fixed flange to stub-end flange or combinations containing blinds. The bolt length definition is a recommendation and does not necessarily have to be followed. The calculated (stud) bolt length needs to be rounded up to the next available bolt length. It is required that full thread engagement is obtained after the assembly.

In Annex A, a flowchart for bolt selection is given.

In Annex D to Annex G, the flange thicknesses of fixed flanges and assembly lengths of stub-end flanges are given for standard products. Special products may have different dimensions; for dimensions of special products FPI shall be contacted.

7.4.1. Bolt length - Fixed flanges

The (stud) bolt length for fixed flanges can be defined using the following calculation method.

Bolt length:Lbolt = 2 · (TF + TFtol + w + p) + g + n

Stud bolt length:Lstudbolt = 2 · (TF + TFtol + w + n + 2 · p) + g

Where: Lbolt = bolt length (mm)Lstudbolt = stud bolt length (mm)TF = flange thickness (mm) flange thicknesses of fixed flanges are given in Annex D, FW flanges table D1 CM flanges table D2 TFtol = tolerance on flange thickness (mm) for FW flanges, ID ≤ 400 mm : + 2 (mm) 450 ≤ ID ≤ 1800 mm : + 5 (mm) for CM flanges, 1900 ≤ ID ≤ 2000 mm : + 8 (mm) 2100 ≤ ID ≤ 3000 mm : + 12 (mm) 3100 ≤ ID ≤ 4000 mm : + 15 (mm) for steel flanges, tolerance as specified by supplierw = thickness of washer (mm) typical washer dimensions are given in Annex Bp = thread pitch (mm) - for metric bolts: thread pitch as per standard - for inch size bolts (UNC): 25.4/Thread Per Inch (TPI) typical pitch and TPI values are given in Annex Bg = thickness of sealing material, as specified by supplier (mm) typical sealing dimensions are given in Annex Cn = nut height; typical nut dimensions are given in Annex B (mm)

7.4.2. Bolt length – Stub-end flanges

The (stud) bolt length for stub-end flanges can be defined using the following calculation method.

Bolt lengthLbolt = 2 · (LA + LAtol + w+ p) + g + n

Stud bolt lengthLstudbolt = 2 · (LA + LAtol + w + n + 2 · p) + g

8. Bolt torques

The bolts of flange joints shall be tightened using the prescribed bolt torques, which are given in tables 1 and 2. These torque values are applicable for ASA 150, ASA 300 and PN 10 to PN 63 drilling patterns in combination with the recommended sealing material as specified in chapter 4.

Bolt torques for other drilling patterns (API/JIS/ASA 600/etc) or for gaskets, other than recommended by FPI, including special gaskets on valves, pumps, etc, might differ from the values given in tables 1 and 2. Recommended bolt torque values for these applications shall be reviewed on a case-by-case basis by the FPI Technical Support team.

9. Supports

Aboveground pipeline systems are installed using supports. When jointing FRP flanges to heavy equipment such as butterfly valves, it shall be ensured that the load due to the weight of the equipment is not transferred to the FRP flange. This load shall be limited by proper supporting of the heavy equipment. The support for heavy equipment should not be connected to the FRP flange. The Wavistrong Engineering Guide provides information on types of supports and on the support to support spans.

10. Misalignment

Flanges shall be properly aligned and shall not be subjected to any overload to meet each other.Flanges are jointed using rubber type sealing elements, small misalignments can be consumed by the flexibility of the sealing element. To prevent overloading of a FRP flange, the bolt torques specified in chapter 8 shall not be exceeded.

An example of exceeded flange parallelism is shown in figure 12. The allowable for flange parallelism is illustrated in figure 13 where the values for ‘x’ are defined in table 3.

11. Assembly instruction

This section describes the assembly of a flange joint. To ensure that the performance of the assembled joint complies with the requirements used for the design, it is essential that all personnel involved in the jointing procedure is familiar with and fully understands the techniques described in this assembly instruction.

The instruction is as complete as possible. However, it is not possible to describe all circumstances that might be encountered in the field. Therefore, our experienced supervisors may deviate from the described method, in order to achieve an optimum solution using the latest techniques and methods.

Besides, our supervisors may be consulted for clarification of statements made in this document and for advice about specific problems encountered in the field.

11.1. Quality

It is advised that the jointer possesses a valid jointer certificate, issued by the pipe manufacturer or a qualified certifier.

11.2. Health and safety

When working with FRP products, the following safety precautions shall be taken:

• Wear at all time suitable protective clothing • Use Personal Protective Equipment (PPE), such as:

- Safety shoes - Safety glasses - Working gloves - Safety helmet (if required by site conditions)

11.3. Tools and consumables

• Torque wrench including box spanner • Ring spanner • Bolts, nuts and washers • Gasket or O-ring • Lubricant; suitable for nuts and bolts • Brush

11.4. Inspection

All pipes, fittings and components used in the pipeline system shall be inspected for damages, prior to the actual assembly activity. Rejected items shall be separated and quarantined from undamaged materials to avoid unintentional use.

Ensure that all the necessary tools and materials are available. Take notice of the safety precautions stated in this document and those as per site conditions.

Fig. 14. Health and safety

Fig. 15. Material required for assembly



11.5. Assembly

The following steps shall be followed to ensure proper assembly of a flange joint.

a Determine the assembly sequence, such that flange assembly in limited spaces will not be blocked by previous assembled components (see fig. 16).

b Flanges shall be properly aligned and shall not be subjected to any overload to meet each other. When using the recommended sealing type, then small misalignments can be consumed by the flexibility of the sealing, the maximum allowed misalignment is defined in chapter 10.

c For stub-end flanges: the loose ring of the stub-end flange shall be positioned centred on the stub-end, such that there is an even distance between the outer diameter of the stub-end and the inner diameter of the loose ring (see fig. 17).

d Bolt holes should be orientated to straddle the centerlines (see fig. 18).

e Clean the flange sealing face and if applicable the O-ring groove. Ensure that the O-ring or gasket and all bolts, nuts and washers are clean. Do not use defective material.

f For assembly using an O-ring: position the O-ring in the groove.

When jointing two flanges with an O-ring seal, only one flange shall have an O-ring groove.

For assembly using a gasket: position the gasket between the two flanges, ensure that the gasket is centred relative to the internal diameter of the flange. The gasket can be centred by inserting a number of bolts, such that the gasket is supported by the bolts. (see fig. 19).

g Lubricate the thread of the bolts (see fig. 20). Use suitable lubricant for bolts, for example a copper paste like Molykote P 1600.

h Insert all bolts in the bolt holes and assemble them using washers and nuts. Bolts and nuts shall have washers to avoid exceeding the allowable surface stress on the FRP flange.

i Ensure that the quality identification on bolts and nuts is visible (see fig. 21).

j First, the bolts and nuts shall be tightened “hand tight”.

k Next, the bolts and nuts shall be tightened using a torque wrench and a spanner (see fig. 22). Tightening shall be as per the bolt torquing sequence as described in ASTM D4024 (see fig. 23). Bolts shall be tightened, following the bolt torque sequence, first up to 60% of the prescribed torque value and next up to 100% of the prescribed value as given in tables 1 and 2.

For flanges having more than 20 bolts, similar alternating bolt tightening sequences shall be used, where required the FPI technical support team may be contacted.

l Finally, the bolts and nuts shall be tightened clockwise using 100 % of the prescribed torque value. This step has to be repeated until all bolts are assembled at the prescribed torque value.

Annex H. Drilling standards

The following tables provide the dimensions for API 75, API 150, ASA 150, ASA 300, ASA 600, JIS 5K, JIS 10K and PN 6 to PN 63 drilling patterns. For diameters ID 3700 mm and above a FPI specific drilling pattern applies, as no standard is available. The dimensions of the flange outer diameter (DU) and bolt hole (d), can slightly deviate from the values given in the related drilling standard. Bolt sizes as specified in API, ASME and AWWA have been converted to metric dimensions.The diameter ranges of the drilling patterns as listed in this annex do not necessarily correspond with the diameter range of FPI flanges.
