A691 91CR High Pressure Welded Tube
GNEE's A691 Grade 91CR Alloy Steel Welded Pipe is produced using a variety of manufacturing processes, including hot working or cold working, and then the pipe is subjected to various tests such as flattening test, hydrostatic test or non-destructive electrical test to ensure that the specified requirements are met.
A691 Grade 91CR High Temperature Pressure Steel Pipe contains 9% chromium and 1% molybdenum and is made from A387/A387M Grade 91 steel plate. Due to the high chromium content, these A691 91CR pressure steel pipes have excellent corrosion resistance, making them a perfect choice for harsh environments.
A691 Gr. 91CR Alloy Steel Pipe has an operating temperature range of 1040 - 1112ºF (560 - 600ºC) and a high pressure range of 4000 psi (270 bar).
