High Performance Sealing Technology
NON-ASBESTOS SHEET JOINTING - INCA
DescriptionInca is a high quality and reliable, yet economically priced jointing based on glass and aramid fibres combined with a nitrile (NBR) binder. It is supplied in a midgreen surface finish. An anti-stick finish to both surfaces is supplied as standard.
Prime features• A durable jointing for general purpose, medium performance, duties.
• Suitable for steam, condensate, water, air, oils, solvents and a wide range of other media.
• Value engineered to provide excellent value for money.
Specification• Readily meets all the requirements of BS 7531 Grade Y.
Physical properties(Typical values for 1.5mm thick material)
Service capabilityFor applications falling into the green zone, the product may normally be used without consultation. In the amber zone we recommend that our technical services team be contacted for confirmation of suitability. If the pressure/temperature combination is in the red zone then we must be consulted before the product is used. Class lines refer to ASME B16.5.
GASKETS & JOINTINGSSetting the seal on gasket technology
Hutton’s working in partnership with James Walker, the specialist in fluid seal technology.
Fluid seal technology is a blend of materials science, fluid mechanics and practical engineering. Our work at the frontiers of these disciplines gives us the clearest understanding of flange sealing techniques and the role that gaskets must play, for example:• If joint faces are absolutely flat and aligned true• If a flange does not distort under load• If loaded bolts do not stretch or relax . . .. . . There is no need for a gasket, because the joint will be perfect.
In the real world, such perfection is very expensive to achieve and almost impossible to maintain. Therefore a gasket is the most practical and cost effective way to seal a bolted flange connection. We hope our guide will assist you in choosing the correct gasket to ensure the integrity and safe operation of your fluid handling equipment.
Tomorrow’s service todayIn the following pages we give details of the range of James Walker’s jointings and gaskets. If off-the-shelf gaskets won’t solve your flange sealing problem, we can organise custom-design products that will.Our high-tech distribution centres are set up to provide the fastest and most reliable service to customers worldwide with a wide range of products ready for immediate dispatch. You can be sure James Walker gaskets and jointings fit the bill.
Don’t...• Never re-use an old gasket.
• Do not use low quality gaskets or jointings. Any initial cost saving will be lost in plant downtime and delays.
• Do not use sealing compounds or grease on joints. They reduce the friction between gasket and flange resulting in stress-relax, creep and premature failure.
• Avoid using impact adhesive or pressure sensitive tapes at temperatures exceeding 40°C. Above this temperature the tackifying resins may melt and act as a lubricant.
• Do not mate flange faces that have different surface finishes.
• Do not retighten bolts after use at elevated temperatures on flanges sealed with gaskets of compressed non asbestos fibre.
General gasket do’s...• Ensure that gasket is compatible with the media at required operating temperature and pressure ranges, and is of the correct dimensions for the flange being sealed.
• Use gasket material and bolt grades that suit the tensile loading requirements of the flange.
• Specify the thinnest gasket that will suit the flange finish and parallelism.• Ensure the flange is clean, undamaged without radial scores, burrs on bolt holes and is free from oil and grease.
• Lubricate bolts and ensure that nuts can run freely down the threads before use.
• Tighten down the gasket evenly in several stages using an approved bolting sequence to ensure equal distribution.
• Use feeler gauges to check required compression.

introduction
The cleaning of cargo tanks can be achieved in a number of ways, but generally, tank cleaning is carried out by utilising the tank cleaning system onboard the vessel.
The tank cleaning system basically consists of an arrangement of distribution piping, which delivers the washing medium via pumps, heaters, valves etc, to either fixed or portable mechanical tank cleaning machine inside the tank.
In most cases, sea water is used as the washing down medium, due to its abundant supply, but in certain circumstance, fresh water is often preferred. Tank wash pumps deliver the washing medium under pressure through heaters (where fitted), which are capable of raising the temperature of the wash water to between 30-90deg C, and to the distribution piping on deck. Heat is a very important factor in the efficiency of tank cleaning operations, and generally, the hotter the water the better the performance. However, the exact contents of the tank residues must be known to avoid problems associated with waxy type residuals and the application of heat. Another deciding factor is the use of chemicals with the washing medium.
The tank washing process is vastly improved by the introduction of UNITOR TANK CLEANING CHEMICALS, specially formulated to increase cleaning efficiency and achieve optimum results.

The wash water/chemical mixture is then fed to the tank cleaning machines, which may be either fixed installations within the tank or the portable type. These machines create powerful jets of water which are forced onto the internal surfaces of the tank or hold it is this action of direct impingement and also splash back of the water/chemical jets combined with the chemical action that achieves cleaning.
The wash water/chemical mixture is continually stripped from the tank bottom during the cleaning operation to a convenient slop tank or chemical mixing tank, depending on the cleaning method adopted. This is to prevent any build up of wash water which would cushion the force of the water/chemical jet, reducing its effectiveness on the bottom.
If there is any liquid remaining in the tank which cannot be drawn off in the usual manner, then this is removed by portable ejectors or pumps. Any liquid remaining thereafter is removed manually.
The cleaning operation is in the majority of cases finalised by manual involvement, i.e, men actually performing the cleaning operation inside the tank. ‘Mucking’ is carried out by men physically removing the cargo residues from the tank bottom and other internal surfaces; ‘Spotting ‘ (cleaning with chemicals in small areas) is carried out where region of the tank or hold have been insufficiently cleaned by other means.

Fuel Oil Treatment
PROBLEM SOLUTION PRODUCT(s)
FUEL SLUDGING
High water content and fuel polymerisation causes sludge formation and filter blocking
Inhibit polymerisation and disperse sludge into combustible state. Demulsify water and stabilise fuel to restore combustion characteristics.
Fuelcare, Gamabreak, Burnaid
HIGH TEMPERATURE CORROSION
A combination of vanadium and sodium results in highly corrosive ashes with low melting points which attack metals causing damage and failure
Raise the melting point of the ashes to keep them as solids. The ashes are then ejected with the exhaust gas.
Valvecare, Dieselite
LOW TEMPRATURE CORROSION
Sulphur and high levels of excess air contribute to the formation of diluted sulphuric acid leading to corrosion
A combustion catalyst enables the reduction of excess air in boilers and resuces the formation of sulphuric acid. In diesel engines the use of ash modifiers inhibits the catalytic action that vanadium has on the SO2->SO3 conversion.
Dual Purpose Plus, Burnaid, Valvecare, Dieselite
ASH DEPOSITS
Carbon residuals from combustion processes bind ash particles together to form deposits
Low excess air; pre-heat temperatures too high: burner/injector malfunction; fouled air coolers; incorrect timing; high MCR fuel, resulting in excessive carbon residue
Check and adjust mechanical functions e.g. Clean air cooler. A combustion catalyst will reduce carbon residue formation.
Dual Purpose Plus, Burnaid, Dieselite
DETERIORATION OF POWER OUTPUT
Ash and carbon deposits in combustion zone and exhaust systems causing general loss of efficiency of boilers and turbocharger surging in diesel engines
Incomplete combustion causes soot and dense carbon based firescale. Gas flow impaired and heat transfer efficiency reduced. Exhaust systems, economisers etc. Become blocked
Catalyically lower carbon ignition temperature, resulting in soot burn off
Soot Remover, Soot Remover Liquid
FUEL SYSTEM CORROSION
Microbiological activity produces a corrosive environment. Salt water contamination of fuel
Kill microbiological contaminant. Neutralise acid, separate out water.
