Why Ductile Iron Pipe?
REXUS Ductile Iron Pipe has exceptional inherent properties that make it highly suitable as a pressure pipe material.Properties include:
High Resistance to Surge and Water HammerDue to its high carbon content, REXUS Ductile Iron Pipe has an inherent damping capacity and a high resistance tocyclic failure. Standard pressure classes allow for high operating pressures. The pipe is also designed with a highsafety factor in excess of 3 times the pipe operating pressure to allow for abnormal surge conditions.
ImpermeableBecause REXUS Ductile Iron Pipe is impermeable contaminated soil cannot penetrate the pipe wall. Combined withthe pipe design's reliable sealing system, this ensures years of reliable operation under all pipeline pressure extremes.
High Flow CapacitiesThe internal diameter of REXUS Ductile Iron pipe is larger than that of any other pipe material. Also, because of itssmooth mortar lining REXUS Ductile Iron pipe provides the least resistance to flow. This ensures a reduction inenergy consumption across the Life Cycle of the system.
Limits Cathodic CorrosionEvery REXUS Ductile Iron Pipe length is insulated from the next with no continuity of current flow. The pipe's highcarbon content also provides a natural resistance to corrosion. The standard coating provides additional protectionand ensures decades of maintenance free operation without need for cathodic protection in most applications.
Coatings and LiningsTo protect against the formation of tuberculation, Ductile Iron pipe is supplied as standard with an active cementmortar lining . External protection is a zinc base coating and bitumen external coat. The long term durability of thesemethods of coating and lining has been proven in thousands of applications. A wide selection of alternative coatingsto suit virtually every application is also available.
JointingREXUS Ductile Iron Pipe makes use of a reliable spigot and socket jointing with a dynamic sealing system. The sealis a pressure fit that allows for partial vacuum conditions in the pipeline without the drawing in of the sea. The integrityof the seal actually increases as the pressure increases. The jointing also allows for angular deflection.
This makes ductile iron pipe easy and quick to lay. REXUS also provides a standard Restrained Seal whicheliminates the need for thrust blocks in soft soil and built up areas. The sealing system is a spigot and socket fit whicheliminates the need for glands, bolts and on site welding.
A Semi Rigid MaterialREXUS Ductile iron Pipe is less reliant upon pipe embedment for support because of the strength and stiffness as itis a semi rigid material. This reduces the need for imported bed and surround, rendering the laying of pipe moreeconomical in comparison to flexible pipe materials. Semi rigid pipe is also highly resistant to vacuum conditions.
High Tensile Strength and Impact ResistanceREXUS Ductile Iron Pipe exhibits tremendous impact resistance. This makes it much less vulnerable to damage fromimproper handling or abnormal service conditions. It has proven its integrity in heavy traffic conditions with unstablesoil environments where other materials might fail due to the stresses caused by unusual loading.
REXUS Ductile Iron Pipe has high tensile strength, a high modulus of elasticity, elongation factor and yield strength.These factors give the pipe the ability to withstand severe stresses caused shifting ground, heavy loads, waterpressure and water hammer.
Lowest Possible Life Cycle CostingREXUS Ductile Iron Pipe’s low installation cost, maintenance free operation, high flow capacities, resistance tocathodic corrosion and a relatively low initial purchasing price provides the lowest Cost of Ownership in comparisonto any alternative pipe.

Standard CoatingREXUS Ductile Iron Pipe is supplied as standard with a metallic Zinc coating of 200g m2 and a finishing layer ofBituminous paint to 100 microns in accordance to BS EN 545 and ISO 8179 specifications. The finishing layer forSewerage application is an Epoxy rich paint in accordance to EN 598 and ISO 8179 specifications.
The Zinc coating with time, transforms into a dense impermeable protective barrier that has the ability to restore thecontinuity of the protective layer through the migration of Zinc ions in areas where local damage may exist. Thebitumen coating provides protection against cathodic corrosion and, a suitable environment for the Zinc coating totransform into an impermeable coating.
Special CoatingsREXUS Ductile Iron pipes and fittings supplied with the standard coating as outlined above can be buried in contactwith the majority of soils. However should special soils and/or conditions such as soils with a low resistivity of lessthan 1500 ohms or soils with a low pH or, soils contaminated by certain wastes, organic or industrial effluent existthen, special coatings should be considered.
REXUS Ductile Iron Pipe and Fittings can be supplied with the following external coatings:· Polyethylene Sleeve to ISO 8180 specifications· Polyethylene Coating to EN 14628 specifications· Polyurethane Coating to EN 15189 specifications· Epoxy Coating to EN 14901 specifications
LiningsREXUS Ductile Iron Pipes are lined internally as standard with cement mortar which is centrifugally applied inaccordance to ISO 4179: 1985 and BS EN 545: 2006/2010. Centrifugally applied mortar provides a high level ofmortar compactness ensures good adherence to the metal and provides a smooth surface which reduces flowresistance.
As a corrosion protection, cement mortar lining is an added advantage to ductile iron pipes. The lining provides aphysical as well as chemical barrier to corrosion of the iron wall. It eliminates red, rusty water and tuberculation.
High Alumina cement lining in accordance to EN 598 is available for aggressive sewer applications and canhandle fluid PH levels of 4 to 12. However, REXUS prefers the use of an Epoxy seal coating in conformance to BS6920 over the standard mortar lining for both soft waters and sewer pipes with high sulphides.
Fittings are also supplied with an internal cement mortar lining. in accordance to BS EN 545 : 2006/2010 and ISO2531 : 2009.
Ductile Iron pipe and Fittings can be supplied with the following liners:· Polyethylene Lining to EN 14628 specifications· Epoxy Lining to EN 14901 specifications· Ceramic Epoxy Lining

REXUS KII Standard JointThe standard spigot and socket push-on flexible joint is used extensively throughout the world on various pipedesigns, and is an extremely reliable joint. Radial compression of the elastomer seal achieves sealing in the REXUSKII Ductile Iron Pipe design. An increase of pressure enhances the sealing due to the specific shape of the sealhousing design and the elastomer seal .
No bolt tightening is necessary apart from normal anchoring precautions on bends and tees, and even in wetconditions, the simple push on connection allows for rapid, low cost pipe laying. The flexibility of the joint also allowsfor long radius bending without the need for additional fittings.
Expansion and contraction is generously accommodated for. In poor and unstable ground conditions, joint flexibilityalso provides an element of safety.
The ductile iron pipe sealing system is also resistant to low negative pressures, and accordingly sealing integrity ismaintained regardless of the operating conditions. As standard, REXUS KII Ductile Iron Pipe is supplied withelastomer seals (SBR / EPDM conforming to EN 681- 1996 / ISO 4633: 1996 / BS 2494 / 1990. The elastomer sealand lubricant is suitable for use with potable water as per BS 6920: 1996
REXUS KII Restraint JointFor socket spigot pipelines, anchorage has traditionally been provided by concrete thrust blocks. In areas wherespace is limited, such as where the underground environment is congested, or the surrounding soil is unstable thiscan prove challenging. Thrust blocks also raise environmental concerns. Because large quantities of concrete mustbe manufactured and transported and similar quantities of spoil correctly disposed of, thrust blocks also raisesenvironmental concerns. Pressure testing is also not possible until the concrete is cured.
The REXUS KII Restraint Joint provides a cost effective, eloquent and efficient restraint. Stainless steel teeth aremoulded into the rubber, and, under pressure, the teeth grip the pipe spigot. This prevents joint separation whilstmaintaining flexibility. However, REXUS KII Restraint Joint gaskets must only be used once. If a new joint made jointafter dismantling , a new gasket will be required.
REXUS KII Restraint Joint gaskets are accredited to BS EN 545 and BS EN 598 specifications. It is available in sizesDN80 to DN600 and for pressure ratings of up to PN25. Joint deflection of up to 5º is achievable.
REXUS KII Mechanical Restrained JointAn additional Restrained Joint solution specifically suited for high pressure and large diameter applications is alsoavailable. The restraining mechanism is incorporated in the normal flexible spigot and socket, offering the samedegree of deflection as that of the REXUS KII Standard Jointing.
The REXUS KII Mechanical Restrained Joint is an external anchoring system. It is available for both water and sewersystems from DN80 to DN1200. It is capable of retaining working pressures up to PN64. The addition of a weld beadto the spigot, a locking ring, bolted gland and hook bolts using the collar on the socket, provides anchorage.
Flanged JointsFlanged Pipe and Fittings are in accordance to ISO 2531/ EN 545 / EN 598 / EN 969 and dimensionally inconformance to SANS 1123 or BS 4504 - PN 10, PN 16, PN 25 and PN 40 as standard. Other flange alignmentsare available on request.
Pipes and Fittings are supplied as standard with PN16 flanges. PN 10, PN 25 and PN 40 flanges are availableupon request.
