A335 Seamless Steel Pipe Description<\/strong><\/b><\/p>\n

ASTM A335 Pipe is a seamless ferritic\u00a0alloy-steel Pipe for high temperature service. Pipe\u00a0of\u00a0this specification\u00a0are\u00a0suitable for bending, flanging, and similar forming operations, and for fusion welding.\u00a0Generally, 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.\u00a0A335\u00a0steel pipe\u00a0not only has high oxidation resistance and high temperature steam corrosion resistance,but also has good impact toughness,stable durable plasticity and thermal strength.\u00a0A335 steel pipes are commonly used to transport high-temperature and high-pressure oil, natural gas and other media.<\/p>\n
