National standard carbon steel elbow standard

National standard carbon steel elbow is a commonly used part, which has a wide range of applications in the industrial field. The national standard carbon steel elbow is designed to ensure its quality and reliability. The following is a detailed expansion of the national standard carbon steel elbow standard.

1. Classification of elbow

National standard carbon steel elbow is divided into different categories according to its bending Angle, the common 45 degree and 90 degree elbow. These elbows are further classified according to parameters such as their inner diameter, wall thickness and material.

2. Material requirements for elbow

The material requirements of the GB carbon steel elbow mainly include the chemical composition and mechanical energy of the material. The chemical composition of the material should meet the relevant standard requirements, such as carbon content, sulfur content, phosphorus content, etc. The mechanical properties include tensile strength, yield strength and elongation of the elbow.

3. Elbow manufacturing process

The manufacturing process of the GB carbon steel elbow should meet the relevant standards. Appropriate processes and equipment should be used in the manufacturing process to ensure the geometry of the elbow, surface quality and smoothness of the inner and outer walls

The size of the GB carbon steel elbow should meet the relevant standards. This includes dimensions such as the inside diameter, outside diameter, wall thickness and bending Angle of the elbow. At the same time, it is also necessary to set the corresponding tolerance range for these dimensions to ensure the connection and installation of the elbow with other pipe fittings.
