1. Oil and gas pipeline: The inner diameter of the pipe should be between 60mm and 200mm, and the wall thickness should be between 6mm and 12mm. The material used should be high-quality steel, and the tensile strength should be no less than 235MPa.2. Water supply and drainage pipeline: The inner dia

Casing Pipe:- Casing pipe is a large-diameter steel pipe used to line the wellbore during the drilling process and the production of oil and gas.- Its primary function is to provide structural support and integrity to the wellbore, preventing collapse and maintaining the integrity of the formation.-

1. Corrosion Resistance: Galvanized steel pipes have a protective zinc coating that provides excellent resistance against corrosion. This coating acts as a barrier, preventing the steel from coming into contact with elements that can cause rust and deterioration.2. Durability: Galvanized steel pipes

1. Dimensions and tolerances: The precise dimensions and tolerances of the tube should be consistent with the requirements of the application.2. Material: The material used for the tube should meet the requirements of the application, such as strength, wear resistance, corrosion resistance, and temp
