ASME SA 269 TP 316 Seamless Tubing
ASTM A269 Seamless Stainless Steel Tubing is used for low temperature and high temperature services. These pipes could be made from austenitic steel types under electric resistant weld, electric fusion weld or seamless cold drawing mechanisms. The SA269 Tubing can also have different finishes and can be heat treated. The SA 269 Tp 316 is more corrosion resistant than the 304 material types and it is used in applications with high pressures and high temperatures as well as low pressure and low temperatures. Therefore the SA 269 Tp 304 and the ASTM A269 Tp316l material grade pipes have different schedules. These schedules correspond to different wall thickness corresponding to different nominal diameters.
