What is ASTM A269 TP316 boiling water pipes ?
ASTM A269 TP316 stainless steel boiling water pipe is an austenitic stainless steel pipe produced in strict accordance with the American ASTM A269 standard. It is made of TP316 material containing molybdenum (2-3%) and is designed for high temperature, high humidity and corrosive boiling water environment. It is widely used in chemical, electric power, food and medicine, seawater desalination and other industries to provide reliable protection for boiling water transmission and heat exchange systems.

What is the difference between TP316 stainless steel and TP304 stainless steel boiling water pipe applications?
TP316 contains 2-3% molybdenum, and has significantly stronger resistance to chloride ion pitting corrosion. It is especially suitable for boiling water environments containing Cl⁻ (such as seawater and chemical wastewater), and its corrosion resistance life is 3-4 times that of TP304. TP316's yield strength (≥205 MPa) and oxidation resistance are also better than TP304.
What is the price of TP316 stainless steel superheater tube?
Because it contains molybdenum, the price is about 1.5-2 times that of TP304, but under high corrosion conditions, the comprehensive cost (life + maintenance) is lower, and the cost performance is significant.
How to calculate the safe working pressure of TP316 boiling water pipe?
P: Maximum allowable pressure (MPa)
S: Wall thickness (mm)
R: 40% of tensile strength (TP316 takes 194 MPa)
D: Outer diameter (mm)
Why choose GNEE
