HIPPS valves are used as the final part of an instrumented system intended to prevent an unacceptably high pressure occurring in downstream equipment. They are always arranged to fail closed and spring/hydraulic actuators are usually the only practical alternative for operation. HIPPS valves are called High Integrity Pressure Protection System (HIPPS) valves In general, closure … Read more
A deluge system is normally the main firefighting system on any offshore installation, used to protect process-areas, drilling-areas and other high-risk areas. A Deluge system is normally an automatic system, which is triggered by a fire detector in the protected area, and which is using water as the extinguishing agent. How piping of deluge system … Read more
Insulating gasket are designed to prevent galvanic corrosion between flanges of dissimilar metals, for example a carbon steel flange bolted to a stainless steel flange. A conducting liquid such as water must be present between the two flanges for galvanic corrosion to occur. On oil and dry gas duties, insulating gaskets are not required. Because … Read more
The Vicker hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a load of 1 to 100 kgf. The full load is normally applied for 10 to 15 seconds. … Read more
Brinell Hardness Test :- The Brinell hardness test method consists of indenting the test material with a 10 mm diameter hardened steel or carbide ball subjected to a load of 3000 kg. For softer materials the load can be reduced to 1500 kg or 500 kg to avoid excessive indentation. The full load is normally … Read more
What is Hardness? Hardness is the property of a material that enables it to resist plastic deformation, usually by penetration. However, the term hardness may also refer to resistance to bending, scratching, abrasion or cutting. Measurement of Hardness: Hardness is not an intrinsic material property dictated by precise definitions in terms of fundamental units of … Read more
Insulating gasket kit are designed to combat the effects of corrosion often found in flanged pipe systems. Galvanic corrosion between dissimilar metal flanges (flow of currents), flange insulation associated with cathodic protection of underground piping are also the places where Insulating gasket kits are used. It consists of Gasket … Read more
Fluid Hammer Fluid hammer:- When the flow of fluid through a system is suddenly halted at one point, through valve closure or a pump trip, the fluid in the remainder of the system cannot be stopped instantaneously as well. As fluid continues to flow into the area of stoppage (upstream of the valve or pump), … Read more
Foundation Loads of piperack should include the loads of Pipes, Cable Trays and Instrumentation duct at that location and also the design load for future tier shall be full load of the most heavily loaded tier in addition to all other wind/seismic/fraction and piping thermal loads for future pipes. Foundation Loads of Piperack Load of … Read more
A static loads is a force that is applied to a structure or object and does not change over time. Static loads are typically caused by the weight of objects, such as the weight of a building or the weight of a car parked on a road. Static loads can also be caused by other factors, … Read more
