Stainless Steel Seamless Pipe , ASTM A312 TP321H For Petrochemical
ASTM A312 TP321H stainless steel seamless pipe is a high-temperature, corrosion-resistant material designed for applications in industries such as petrochemical, power generation, and chemical processing. It is part of the 300-series austenitic stainless steels and is particularly recognized for its excellent strength and durability under high-temperature conditions.
Key Features of ASTM A312 TP321H Stainless Steel Seamless Pipe
Material Composition:
1. TP321H is a stabilized stainless steel alloy with the addition of titanium (Ti) to prevent carbide precipitation during welding and high-temperature exposure.
The "H" designation indicates higher carbon content, enhancing its creep strength for elevated temperature applications.
2. High-Temperature Resistance:
Designed to sustain prolonged exposure to high temperatures (up to 900°C or 1652°F) without losing mechanical strength or forming harmful carbides.
Suitable for heat exchangers, superheater tubes, and other high-temperature environments.
3. Corrosion Resistance:
Excellent resistance to oxidation and intergranular corrosion due to the stabilization from titanium.
Performs well in environments containing acids, salts, and other corrosive agents.
4. Seamless Pipe Construction:
Seamless construction ensures uniform strength and eliminates the risk of weak points associated with welding seams.
Ideal for applications requiring high pressure and temperature stability.
Applications
ASTM A312 TP321H stainless steel seamless pipes are widely used in industries requiring high performance at elevated temperatures. Some typical applications include:
· Heat exchangers and condensers
· Boilers and superheaters
· Furnace components
· Oil and gas pipelines
· Chemical processing equipment
· Power plants

Benefits
· Long-term durability: Enhanced creep resistance due to high carbon content.
· Weldability: The addition of titanium reduces the risk of weld decay.
· Versatile performance: Retains mechanical properties under high-temperature and corrosive conditions.
· Low maintenance: Corrosion resistance reduces the need for frequent replacements.
