Stainless steel seamless pipe implementation standards

Stainless steel seamless pipes are high-quality products increasingly used across various industries due to their superior properties. This article will briefly introduce stainless steel seamless pipe implementation standards.

American Standards:

ASTM Standard:

ASTM A312/A312M-19a: This specification covers seamless, welded, and heavily cold-worked austenitic stainless steel pipes intended for high-temperature and general corrosive service. It includes various grades, such as 304/304L, 316/316L, and others, with sizes ranging from 1/8 inch to 24 inches. Mechanical properties include hardness, tensile strength, and elongation.

German Standards:

DIN Standard:

DIN Standard: Issued by the German Institute for Standardization, these standards include the classification, technical requirements, dimensions, and allowable deviations for stainless steel materials.

Japanese Standards:

JIS Standard:

JIS Standard: Published by the Japan Industrial Standardization Association, these standards specify the size, chemical composition, and mechanical properties of stainless steel seamless pipes.

European Standards:

EN Standard:

EN 10216-5: This European standard specifies the requirements for seamless stainless steel pipes for pressure purposes. Materials include grades like X2CrNi19-11, X5CrNi18-10, and X6CrNiTi18-10. Sizes range from 6mm to 508mm, with mechanical properties such as hardness, tensile strength, and elongation.

BS Standard:

BS Standard: Issued by the British Standards Institution, these standards outline the manufacturing, quality control, and inspection requirements for stainless steel materials.

Chinese Standards:

GB Standard:

GB/T 14976-2012: This national standard is applicable to stainless steel seamless pipes used in manufacturing pressure vessels, chemical equipment, and accessories. Materials include chromium-nickel stainless steel, duplex stainless steel, and corrosion-resistant alloy steel, with sizes ranging from 6mm to 630mm. Mechanical properties include hardness, tensile strength, and elongation.

JB Standard:

SY/T 6267-2006: This petroleum and petrochemical industry standard applies to the manufacture of stainless steel seamless pipes for the petroleum and petrochemical fields. Materials include duplex stainless steel, chromium-nickel stainless steel, and high-temperature alloy series, with sizes ranging from 17.15mm to 508mm. Mechanical properties include hardness, tensile strength, and elongation.

CB/T Standard:

CB/T 4084-2018: This standard specifies the technical conditions for marine stainless steel seamless pipes used in shipbuilding. The primary material is chromium-nickel stainless steel, with sizes ranging from 10mm to 160mm. The mechanical properties mainly include tensile strength and elongation.
