Stainless steel seamless pipe is an important pipe material, which has the characteristics of high temperature resistance, corrosion resistance, pressure resistance and easy processing. This article will introduce the manufacturing process, characteristics and applications of stainless steel seamless pipes.
Here is the outline:
Manufacturing process of stainless steel seamless pipe
Characteristics of stainless steel seamless pipe
Application of stainless steel seamless pipe
steelmaking
The manufacturing process of stainless steel seamless pipe starts with steelmaking. Stainless steel is an alloy containing elements such as chromium, nickel, molybdenum, etc. These elements can make stainless steel have the characteristics of corrosion resistance and high temperature resistance. Therefore, in the process of steelmaking, a certain amount of these elements needs to be added.
Billet
After refining the stainless steel that meets the requirements, it needs to be cast into a billet. Casting methods include continuous casting, pouring and other methods.
hot rolled
The cast slab needs to be processed by hot rolling to form a certain size of plate or strip. In this process, parameters such as rolling temperature and rolling force need to be controlled.
heat treatment
The hot-rolled stainless steel sheet needs heat treatment to change its crystal structure and improve its physical properties.
cold drawn
The heat-treated sheet needs to be cold-drawn to further improve its surface finish and dimensional accuracy.
finishing
The cold-drawn sheet needs to be finished to achieve higher dimensional accuracy and surface quality.
Seamless pipe production
The finished stainless steel sheet needs to go through multiple processes such as crimping, perforation, pickling, etc. to be made into a seamless tube.
features
Stainless steel seamless pipe has the following characteristics:
High temperature resistant
Stainless steel seamless pipe can work in high temperature environment, its heat resistance is excellent, and there will be no oxidation, delamination and other phenomena.
preservative
Stainless steel seamless pipe has excellent corrosion resistance and can withstand the corrosion of various media such as acid, alkali, and salt.
withstand voltage
Stainless steel seamless pipes can withstand high pressure, and their strength and hardness are higher than ordinary steel pipes.
Easy to process
Stainless steel seamless pipes are easy to process and connect, and can meet various needs.
Stainless steel seamless pipes are widely used in chemical, petroleum, pharmaceutical, food, aerospace, metallurgy and other fields. Specific applications include the following aspects:
chemical industry
Stainless steel seamless pipes can be used to convey various chemical media, such as acids, alkalis, salts, etc. In chemical production, the requirements for pipelines are relatively high. Stainless steel seamless pipes have become the preferred material for chemical pipelines because of their good corrosion resistance and high temperature resistance.
oil
Stainless steel seamless pipes are widely used in oil exploration, refining and other fields. In offshore oil and gas exploration, it is necessary to use corrosion-resistant and high-pressure pipelines, and stainless steel seamless pipes can meet this demand.
pharmaceutical
Stainless steel seamless pipes are widely used in the pharmaceutical field. The pharmaceutical industry has relatively high requirements for pipelines, requiring smooth surfaces and not easy to breed bacteria. Stainless steel seamless pipe has high surface finish, easy cleaning, and no secondary pollution, so it has become the material of choice in the pharmaceutical industry.
