ASTM A53 Steel pipe tube oil steel pipe for plumbing| China manufacturer-Cangzhou Hongxin

What is a Steel Pipe? 

A steel pipe is a cylindrical hollow tube made primarily from steel, designed to transport fluids, gases, solids, or serve structural purposes. Its versatility, strength, and durability make it a fundamental component across industries such as construction, oil and gas, plumbing, and manufacturing. Steel pipes are manufactured in various sizes, thicknesses, and specifications to meet diverse operational demands.

Types of Steel Pipes

• Seamless Steel Pipes

Produced by extruding solid steel billets without any welding seam.

Ideal for high-pressure applications (e.g., oil and gas pipelines).

Standards: ASTM A106, API 5L.

• Welded Steel Pipes

Formed by rolling steel plates or coils and welding the seams.

Subtypes:

ERW (Electric Resistance Welded): For low-to-medium pressure systems.

LSAW (Longitudinal Submerged Arc Welded): For large-diameter pipelines.

SSAW (Spiral Submerged Arc Welded): For structural and fluid transport.

Standards: ASTM A53, ASTM A672.

• Galvanized Steel Pipes

Coated with zinc to resist corrosion.

Commonly used in plumbing, fencing, and outdoor structures.
