What is the ASTM standard for carbon steel pipe?

The American Society for Testing and Materials (ASTM) has developed a variety of standards for carbon steel pipes, which specify in detail the size, shape, chemical composition, mechanical properties and other technical requirements of steel pipes. The following are several common ASTM standards for carbon steel pipes:

1. Seamless Carbon Steel Pipes

ASTM A53: Applicable to welded and seamless black and hot-dip galvanized steel pipes, widely used for structural purposes, piping systems, etc. This standard is divided into three grades: A, B, and C according to wall thickness.

ASTM A106: Seamless carbon steel pipes suitable for high temperature service, divided into Grade A, B, and C, mainly used in oil, natural gas transmission pipelines and chemical industries.

ASTM A519: Applicable to precision seamless carbon steel bars and pipes for machining, with strict dimensional tolerance requirements.

2. Welded Carbon Steel Pipes

ASTM A500: Applicable to cold-formed welded and seamless square, rectangular and other shaped structural steel pipes, commonly used in building structures.

ASTM A501: Applicable to hot-rolled welded and seamless square, rectangular and other shaped structural steel pipes.

ASTM A513: Applicable to electric welded round steel pipes, commonly used for machining and structural applications.

3. Carbon steel pipes for boilers and superheaters

ASTM A179: Applicable to cold-drawn low-carbon steel boiler pipes, suitable for high-pressure steam applications.

ASTM A210: Applicable to seamless carbon steel boiler pipes, divided into four grades: A1, A1P, A2, and A2P, mainly used for medium and low pressure boilers.

ASTM A335: Applicable to seamless ferritic alloy steel high-temperature service pipes, divided into multiple grades, such as P1, P5, etc., suitable for high-temperature pipelines in the petrochemical and power industries.

4. Carbon steel pipes for oil and gas wells

ASTM A252: Applicable to spiral seam submerged arc welded steel pipes for piles, commonly used in offshore platform construction.

ASTM A506: Applicable to high-strength low-alloy structural steel pipes, suitable for oil and gas field equipment manufacturing.

ASTM A672: Applicable to high yield strength carbon manganese silicon steel pipes, suitable for applications requiring higher strength.

API Spec 5L: Although not an ASTM standard, it is an internationally accepted standard for steel pipes for oil and gas pipelines, which covers many types of carbon steel pipes.

5. Carbon steel pipes for special purposes

ASTM A312: Applicable to stainless steel seamless and welded pipes. Although it is mainly for stainless steel, it also includes some carbon steel specifications.

ASTM A795: Applicable to carbon steel and alloy steel billets, round billets and their products made by continuous casting and forging, suitable for specific industrial fields.

How to choose the right ASTM standard

Choosing the right ASTM standard depends on the specific application requirements:

Use environment: Consider factors such as operating temperature, pressure conditions, and the presence of corrosive media.

Mechanical properties: Determine the required minimum yield strength, tensile strength and other key indicators.

Dimensional accuracy: For some precision machining or assembly applications, more strictly controlled outer diameter and wall thickness tolerances may be required.

Surface treatment: Whether hot-dip galvanizing, painting or other forms of anti-corrosion treatment are required.
