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
Variable Spring Hanger: A variable spring hanger is a type of support used for piping systems. It is designed to allow for thermal expansion and contraction of the piping without causing damage. The variable spring hanger consists of a spring that is mounted between two flanges. The spring is designed to compress and expand as … Read more
Stainless steel pipe is a sort of line produced using tempered steel, a metal that doesn’t rust and has something like 10.5% chromium in it. This high chromium content makes an oxide layer on the surface of the steel that protects it from rust and corrosion. This makes it perfect for many uses where durability … Read more
H2S corrosion:- The presence of H2S corrosion may give rise to three principal types of cracking in steels. These are sulphide stress cracking (SSC) and stress corrosion cracking (SCC), which result from the joint action of corrosion and tensile stress (residual or applied) in the presence of water and H2S corrosion may occur in carbon … Read more
Isolation Philosophy describes methods for isolating sections of plant to permit safe operation, and provide access for maintenance or inspection. The methods described here are applicable for all hazardous and non-hazardous process and utility systems. Provision shall be made to isolate all equipment, either separately or commonly, within a process or non-hydrocarbon system. Maintenance isolation … Read more
A scrapper tee, also known as a flow tee or barred tee, is a type of pipe fitting that is used to ensure the safe passage of pipeline pigs across branch connections. A pig is a tool that is inserted into a pipeline to clean, inspect, or modify the pipeline. The scrapper tee has a … Read more
Duplex Stainless Steel Type Duplex stainless steel DSS is divided into two sub-families, DSS (22%Cr) and SDSS (25%Cr). SDSS has better corrosion resistance and may also be used for seawater service. SDSS may be preferred to DSS also for its higher strength, resulting in reduced wall thickness, which may be of interest and even necessary for … Read more
