ASTM Stainlessl Steel Pipe factory

This is the most widely used type of pressure piping system used to transport fluids.

ASTM A312 / A312M: Standard Specification for Seamless and Welded Austenitic Stainless Steel Pipe

Status: The most core and universal stainless steel pipe standard.

Scope: Covers seamless, welded, cold-finished, or hot-finished austenitic stainless steel pipe. Suitable for high and low temperatures and corrosive environments.

Common grades: TP304/304L, TP316/316L, TP321, TP347, etc.

ASTM A358 / A358M: Standard Specification for Electric-Fusion-Welded Austenitic Chromium-Nickel Alloy Steel Pipe

Features: Suitable for larger diameter pressure piping. Arc welding (such as plasma welding or TIG welding) is typically used with the addition of filler metal, requiring high weld quality.

ASTM A790 / A790M: Standard Specification for Seamless and Welded Ferritic/Austenitic (Duplex) Stainless Steel Pipe

Features: Specifically designed for duplex stainless steels, offering high strength and resistance to chloride stress corrosion cracking.

Common grades: S31803, S32205 (2205 duplex steel), S32750 (2507 super duplex steel).

ASTM A928 / A928M: Standard Specification for Electric Fusion-Welded Ferritic/Austenitic (Duplex) Stainless Steel Pipe with Filler Metal

Features: Equivalent to the A358 standard for duplex stainless steel, specifically for welding processes.
 

(especially heat exchanger tubes) are used in the manufacture of heat exchangers, boilers, condensers, and other applications. These tubes place extremely high demands on uniformity, dimensional accuracy, and pressure-bearing capacity.

ASTM A213 / A213M: Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Tubes for Boilers, Superheaters, and Heat Exchangers

Features: Designed specifically for seamless heat exchange tubes.

Grade: Overlaps with A312, but with more stringent requirements.

ASTM A249 / A249M: Standard Specification for Welded Austenitic Steel Tubes for Boilers, Superheaters, Heat Exchangers, and Condensers

Features: Designed specifically for welded heat exchange tubes, requiring weld properties consistent with those of the parent material.

ASTM A688 / A688M: Standard Specification for Welded Austenitic Stainless Steel Feedwater Tubes for Boilers, Superheaters, Heat Exchangers, and Condensers

Features: Designed for welded tubes for specific applications.

Primarily used for mechanical components, structural supports, furniture, and decoration, it is not intended for conveying fluids under pressure. Emphasis is placed on dimensional accuracy, surface finish, and mechanical properties.

ASTM A554: Standard Specification for Welded Stainless Steel Pipe for Mechanical and Decorative Use

Status: The most commonly used standard for mechanical structural pipe.

Scope: Covers welded pipes in square, rectangular, round, and other shapes.

Grades: MT304, MT316, etc. (corresponding to A312, but with different performance specifications).

ASTM A511: Standard Specification for Seamless Stainless Steel Mechanical Pipe

Features: Corresponds to seamless products of A554.

ASTM A778: Standard Specification for Welded Unannealed Austenitic Stainless Steel Tubular Products

Features: Applicable to welded pipes that are not heat treated (annealed) after fabrication and are used for non-pressure applications.

Its scope of application lies between pressure pipe and mechanical pipe, and is commonly used for process piping in the instrumentation, food, and pharmaceutical industries.

ASTM A269 / A269M: Standard Specification for Seamless and Welded Austenitic Stainless Steel Pipe for General Service

Features: Highly versatile, often used in non-boiler and non-heat exchange applications where cleanliness and corrosion resistance are critical.

These standards define the chemical composition, mechanical properties, and other aspects of stainless steel plate and serve as the basis for steel pipe material.

ASTM A240 / A240M: Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels

Importance: The chemical composition and mechanical properties of stainless steel grades (such as 304 and 316) referenced in standards such as A312 and A213 generally follow the specifications of A240.

These standards specify the outside diameter and wall thickness series of steel pipe.

ASME B36.19M: Stainless Steel Pipe

Note: Although this is an ASME standard, it is used in conjunction with ASTM standards in the North American pressure piping industry and serves as the de facto dimensional standard. It specifies the nominal size (NPS) and wall thickness series (such as SCH 5S, 10S, 40S, and 80S) of stainless steel pipe.

ASTM A530 / A530M: Standard Specification for General Dimensional Requirements for Stainless Steel Pipe

Description: ASTM's own general dimension standard.

Specifies how to test various properties of steel pipe.

ASTM A1016 / A1016M: Standard Specification for General Requirements for Ferritic Alloy Steel, Austenitic Alloy Steel, and Stainless Steel Pipe

Importance: This is a very important "general requirements" standard. It brings together test methods, inspection rules, and retest rules common to multiple product standards, including A213, A249, A312, and A790. A1016 is often referenced when reading specific product standards.
