ASTM A335 Seamless Alloy Steel Pipe Specifications

A335 Seamless Steel Pipe Description

ASTM A335 Pipe is a seamless ferritic alloy-steel Pipe for high temperature service. Pipe of this specification are suitable for bending, flanging, and similar forming operations, and for fusion welding. Generally, ASTM A335 P11, P22, and P91 pipelines are used for power generation and downstream oil and gas, and P5 and P9 grades are used for refinery applications. A335 steel pipe not only has high oxidation resistance and high temperature steam corrosion resistance,but also has good impact toughness,stable durable plasticity and thermal strength. A335 steel pipes are commonly used to transport high-temperature and high-pressure oil, natural gas and other media.
