Gnee offers SS pressure pipe rated for 150,000 psi (10342 bar) operating pressures in sizes ranging from 1/4" to 1" pipe diameter. Standard pipe materials are 316 and 304 treated steel pipe. Hardened steel high-pressure pipe is used as a liquid protection component in the composite/petrochemical, research, and oil and gas industries. We specialize in supplying high-diameter seamless high-pressure pipes in 304 and 316 steel grades, which have very high corrosion resistance.
SS High Pressure Pipe is a pipe used to transport high-pressure gas, usually made of stainless steel, with excellent corrosion resistance and high strength. Stainless steel pressure pipes are widely used in chemical industry, petroleum, natural gas and other fields. They can withstand high pressure and temperature and have a long service life.
Stainless steel pressure pipe is a component of a piping system used to withstand high-pressure liquid or gas, usually made of stainless steel. These pipes are widely used in applications requiring excellent corrosion resistance, high strength and long life.
Seamless stainless steel pressure pipes usually use stainless steel alloys. Common stainless steel materials include 304, 316, 321, etc. The choice of different materials depends on specific application requirements, such as corrosion resistance, strength and high temperature performance.
