Casing  pipe strength is closely related to the mechanical properties of the octg casing material, including yield strength, tensile strength, compressive strength and shear strength.

In order to ensure the quality and safety of steel sheet piles, it is particularly necessary to formulate a standard specification.

Black welded steel tube refers to a welded pipe with a black surface.

Seamless OCTG casing is a casing made of seamless steel pipe as raw material.

U type steel sheet pile, also known as cold-formed steel sheet pile, is a high-strength, high-quality building material that is widely used in foundation projects, water conservancy projects and support structures of structures.

OCTG stands for "Oil Country Tubular Goods," which refers to a category of specialized steel pipes used in the exploration, production, and transportation of oil and natural gas.
