Carbon Seamless Steel Pipe

Specification

Description

Standard Sizes and Dimensions

Available in a wide range of diameters and wall thicknesses, following nominal pipe sizes (NPS) and schedules (e.g., Schedule 40, Schedule 80).

Wall Thickness

Varies depending on application; thicker walls provide higher pressure ratings and strength.

Material Grades

Common grades include: – ASTM A106: High-temperature and high-pressure applications. – ASTM A53: Low to medium pressure applications (water, steam, air). – API 5L: Oil and gas pipelines with corrosion resistance. – ASTM A333: Low-temperature service, cryogenics.

Manufacturing Process

Made without seams by piercing a solid billet and elongating it into a hollow tube through hot rolling or cold drawing.

End Finishes

Can have plain ends, beveled ends, or threaded ends to facilitate pipe joining.

Surface Finish

Includes smooth or coated finishes such as: – Galvanization: Zinc coating for corrosion resistance. – Epoxy Coatings: Protection against corrosion in harsh environments. – Paint Linings: Added durability and corrosion protection.

Pressure and Temperature Ratings

Varies by grade and wall thickness, with specific ratings for high-temperature and high-pressure applications.

Compliance with Standards

Manufactured to meet ASTM, API, and ISO standards for safety, quality, and performance.

Tensile Strength and Yield Strength

Tested for tensile strength and yield strength to determine force limits before deformation or failure.
