ASTM A335 P91 pipe as ASME SA335P91 Chrome-Moly pipe, it is a type of seamless pipe could be used in high temperature environments of 540 – 750 °C. It is suitable for bending, flanging, and similar forming operations, and for fusion welding. BBN steel can produce and export ASTM A335 P91 high pressure boiler pipes with large quantity.
ASTM A335 Grade P91 boiler pipe is a good grade pipe applied for high pressure boiler. And P91 pipe is ideal when it comes to bending, flanging or when it is used in similar operations such as welding. The material of steel should stick to the composition of chemicals, tensile property and the requirements of hardness.
ASTM A335 P91 alloy steel pipes are the two variants available and the range is dependent based on the size, which is solely based on the usage. The length of the pipe will be subject to hydrostatic test and there will also be a non-destructive examination based on the specifications.
As a result, The A335 P91 chrome moly pipe finds high usage in power generation industry and petrochemical industry owing to its resistance to corrosion, tensile strength, strength for high temperature owing to its cost-effectiveness.
