What are the Standards of ASTM A312, A358, A778 and JIS G3459?
ASTM A312:
Definition: This standard covers the specifications for seamless, welded, and highly cold-finished stainless steel pipes for high-temperature and general corrosive environments.
Application: Mainly used in industrial piping systems for conveying fluids and gases, such as chemical, petrochemical, food processing, nuclear power, and other industries.
Material: Usually covers austenitic stainless steel, such as 304, 316, etc.
ASTM A358:
Definition: This standard applies to stainless steel arc-welded pipes (usually double-sided welded steel pipes) for high-temperature service or general corrosive environments.
Application: Similar to A312, but more focused on the use of thick-walled pipes, often used in piping systems that require additional strength or thickness.
Material: Usually also austenitic stainless steel.
ASTM A778:
Definition: This standard specifies the requirements for welded stainless steel pipes for low-pressure corrosive environments. Unlike A312, it does not require full heat treatment.
Application: Widely used in environments that require corrosion resistance but do not need to withstand high pressure or high temperature, such as construction, food processing, sewage treatment, etc.
Material: Covers a variety of austenitic stainless steels.
JIS G3459:
Definition: This is a Japanese industrial standard that mainly deals with the manufacturing requirements of stainless steel pipes, especially for industrial use in general corrosion-resistant environments.
Application: This standard pipe is widely used in chemical, petroleum, food industry, and other similar environments.
Material: Similar to ASTM standards, it is usually austenitic stainless steel, such as 304, 316, etc.
Industrial Applications
Stainless steel welded pipes are highly corrosion-resistant and incredibly durable, making them ideal for use in demanding environments. These pipes are commonly used in industries such as:
- Chemical
- Food and beverage
- Marine
- Mining
- Oil and gas
- Pharmaceutical
- Petrochemical
- Power generation
- Renewable energy
Welded stainless steel pipes are often more cost-effective to produce than seamless pipes for applications requiring resistance to corrosion. As a distributor of ASTM A312 and A358 welded pipes, we can supply the materials you need to complete your projects on time and within budget.
ASTM A312 vs ASTM A358
What is ASTM A312?
ASTM A312 TP 304 / 304L stainless steel pipe is the most widely used and commonly used stainless steel on the market. These grades are austenitic chromium alloys, also known as “18/8” stainless steels because the composition of the steel is 18% chromium and 8% nickel. The common grades for this specification are 304/304L and 316/316L.
What is ASTM A358?
ASTM A358 is a specification for electric-fusion-welded austenitic stainless steel pipe that performs well in high-temperature industrial applications.
