The steel pipe whose outer diameter to wall thickness ratio is less than 20 is called thick wall steel pipe. It is mainly used as drilling pipe for petroleum geology, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural pipe for automobile, tractor and aviation.

Application:

1. Structural pipes. For example, steel bars used for building structures must be processed by pressure after they are made into components. Special-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel. Pipes or structural parts used to convey fluids.

2. Pipe for mechanical structure. Such as high-quality carbon structural steel hot-rolled seamless steel pipes, cold-drawn precision seamless steel pipes and thermally expanded seamless pipes for special purposes that are widely used in the manufacture of mechanical parts.

3. Pipes for petroleum geological drilling. It is a seamless steel pipe with internal or external thickening at both ends of oil drilling. Based on the drilling results, is the decision to use a cone drill or a twist drill. Is to take deepening or drag reduction measures.What kind of tubing should be selected to prevent lost circulation..What kind of joint is used to weld the oil pipe so that it will not leak. Questions such as these are all concluded by studying the role of thick-walled steel pipes;

4. Electric furnaces for chemical industry and electric heating steam pipes for fluid delivery in high-temperature and high-pressure boilers;

5. Seamless steel pipes used in other departments.

Diameter and length,can do as request of customers,do customized.
