ASTM A312 TP904L, Stainless Steel Seamless Pipe, For Pipeline, High Anti-Corosion

Product Overview:

The ASTM A312 TP904L Stainless Steel Seamless Pipe is specifically designed for pipeline applications where high anti-corrosion properties are essential. 904L stainless steel is a highly alloyed austenitic stainless steel, which provides exceptional resistance to corrosion, especially in aggressive environments. This material is widely used in chemical processing, oil and gas, and marine applications where resistance to pitting, crevice corrosion, and stress corrosion cracking are crucial.

Key Features

1. Material: ASTM A312 TP904L Stainless Steel

• ASTM A312 TP904L is a high-alloy austenitic stainless steel that contains high levels of chromium (19%) and nickel (23%), along with molubdenum and copper.

• This unique composition provides superior resistance to corrosion, particularly in chloride-rich environments, acidic solutions, and sea water, making it ideal for pipelines in industries such as chemical processing, petrochemical, and marine systems.

• 904L stainless steel offers excellent weldability, formability, and ductility, ensuring that it performs well in both high-pressure and high-temperature applications.

2. Corrosion Resistance

• 904L stainless steel is highly resistant to pitting and crevice corrosion, stress corrosion cracking, and general corrosion in chloride-rich environments.

• It is particularly effective in sulfuric acid and phosphoric acid environments, making it ideal for use in chemical pipelines or applications where the material will be exposed to corrosive fluids.

3. Seamless Pipe

• Seamless pipe construction ensures that the pipe is stronger and more reliable than welded alternatives. The seamless process guarantees uniform thickness, no welded seams, and smooth inner surfaces, which are crucial for fluid flow efficiency and long-term performance in high-pressure pipelines.

4. Application: Pipelines in Chemical, Petrochemical, Marine, and Oil & Gas Industries

• ASTM A312 TP904L Stainless Steel Seamless Pipes are commonly used in high-corrosion applications, including chemical processing plants, marine environments, seawater pipelines, and oil and gas pipelines, where protection against corrosion and high-pressure endurance are critical.
