What is ASTM A269 specification?
ASTM A269 is a standard specification that covers seamless and welded austenitic stainless steel tubing for general corrosion-resisting and low-to-high temperature service.
What is ASTM A269 TP316 Stainless Steel Pipe?
ASTM A269 Tp316 is a grade of seamless and welded austenitic steel with nominal wall thickness that is designed with 316 austenitic stainless steel. The ASTM A269 Tp316 Tube is composed of an outstanding content of 16% chromium with 10% nickel and 2% of molybdenum.GNEE manufacturers supply 1.4401 AISI 316 seamless and welded pipes in many types.

What is the difference between TP316 and 316L?
TP316 is derived from the classic "18-8" (TP304) stainless steel by adding molybdenum for enhanced pitting resistance in chloride environments. TP316L is the low carbon version of TP316, in which low carbon content improves sensitization for better welded corrosion resistance.
Advantages of ASTM A269 TP316 seamless Pipe
Corrosion Resistance: The ASTM A269 TP316 seamless pipe is highly resistant to corrosion, which makes it ideal for use in harsh environments. It can withstand exposure to water, saltwater, acids, and other corrosive substances without rusting or corroding.
Heat Resistance: The ASTM A269 TP316 Stainless Steel Seamless Pipe is also highly heat resistant, which makes it suitable for use in high-temperature environments. It can withstand temperatures up to 1500°F (816°C) without losing its strength or durability.
Durability: The Stainless Steel TP316 Schedule 40 Pipe is made from high-quality materials that are designed to last. It is highly durable and can withstand years of use without needing to be replaced.
