اسtainless steel tube Specification
Stainless steel tube specifications vary depending on the intended use and application. Some common specifications include:
- ASTM A269: This specification covers seamless and welded austenitic stainless steel tubes for general use, such as in chemical and petrochemical processing, pharmaceutical production, and food and beverage processing.
- ASTM A312: This specification covers seamless, welded, and heavily cold worked austenitic stainless steel pipes for high-temperature and general corrosive service, such as in oil and gas production, pulp and paper processing, and power generation.
- ASTM A554: This specification covers welded stainless steel mechanical tubing for ornamental, structural, and decorative applications, such as in handrails, balustrades, and architectural features.
- ASTM A270: This specification covers seamless and welded austenitic stainless steel sanitary tubing intended for use in the dairy, food, and beverage industries.
Other important factors to consider when choosing stainless steel tube specifications include material grade, size, ضخامت دیوار, and surface finish. Common material grades include 304/304L, 316/316L, and duplex stainless steels such as 2205. Sizes typically range from 1/8 inch to 36 inches in diameter, with wall thicknesses ranging from 0.5mm to 50mm or more. Surface finishes may include annealed, pickled and passivated, polished, or buffed.
