Total RC is standardising on manifolds produced by the Instrumentation Products Division of Parker Hannifin. The decision follows several years’ extensive temperature, pressure and corrosion testing of products from different manufacturers – Parker is the first company to have secured a 100 percent pass rate.
Under the terms of the contract, Parker will supply all the instrumentation manifolds that Total RC needs for new installations and upgrades across its entire European base of refining and petrochemical operations. Most of the company’s requirements will be for manifolds designed to connect process transmitters to ANSI Class 1500 or 600 piping, together with some for use with pressure gauges and lower rated instrumentation tubing.
The manifolds cover a diverse range of 2-, 4- and 5-valve configurations. They all either feature flanged inlets and outlets, or utilise Parker’s PTFree connect system. All of the Class 600 and 1500 manifolds that Parker will supply under this contract are NACE MR0175/ISO 15156 compliant and rated for service in sour gas (H2S) environments. All metallic components are manufactured from heat code traceable 316 stainless steel. The valves are high performance globe style bonnet designs, with externally adjustable sealing glands and Graphoil packing. Every manifold includes steam trace ports for heat tracing and all vent valves feature anti-tamper bonnets.
