Knowledge of stainless steel clad plate

With the continuous development of science and industry, it is difficult for ordinary alloys or a single metal to meet the requirements of industrial development for the comprehensive properties of materials. The clad plate made by different processes just meets the special comprehensive performance requirements. The hot-rolled stainless steel clad plate produced by the stainless […]

How can stainless steel tubes avoid deformation or concave flattening

Stainless steel pipe is a kind of steel. Before it is made into a product, it is in three conventional shapes such as round, rectangular and square in people’s eyes. According to the needs of different products, there are many kinds of stainless steel thicknesses, both thick and thin. During the process of loading, unloading, […]

How to scientifically arrange the production of hot-dip galvanized spiral steel pipe

How to scientifically arrange the production of spiral steel pipes The production of spiral steel pipe is due to its slow adjustment process and fast production. Under normal circumstances, it is not often adjusted, because the adjustment generally requires a half-sound time. If it is produced, this half-sound can produce about 30 tons of steel […]

Flatness galvanized steel pipe

Galvanized steel pipes are divided into cold galvanized steel pipes and hot-dip galvanized steel pipes. Cold galvanized steel pipes are strictly prohibited from being used, and the latter one is advocated for temporary use in my country. In the 1960s and 1970s, the international bourgeoisie in my country slowly developed designs and designs for new […]

Knowledge of the application and precautions of polyurethane thermal insulation steel pipe

Polyurethane direct buried thermal insulation pipe is suitable for thermal insulation and cold insulation projects of various media in the range of -50℃~150℃. It is widely used in thermal insulation and cold insulation projects in urban central heating, warm room, cold storage, coal mine, petroleum port, chemical industry and other industries. Knowledge of the application […]

Common anti-corrosion coatings for national standard spiral steel pipes

The national standard spiral steel pipe refers to the steel pipe that is used and transported as a medium, and the steel pipe is corroded by chemical or electrochemical reactions due to the influence of the use environment and the conveying medium. The quality of the coating construction has a great influence on the performance […]

Welding process of 304 lined stainless steel composite pipe

Welding process of 304 lined stainless steel composite pipe (304+Q235B) is a new type of composite pipe, which has the characteristics of corrosion resistance, high temperature resistance, high elongation, high strength, etc. It is widely used in the process pipelines of new and expanded petrochemical plants. The biggest use problem of this kind of pipe […]

What are the advantages of heat treatment of Q345D seamless steel pipe?

In order to better improve the tensile strength and wear resistance of the surface of Q345D seamless steel pipe, we need to carry out some surface treatment of metal materials during the production process. Are there any characteristics of Q345D seamless steel pipe? Model specification reliability For precision machining of rectangular square tubes, precision machining […]

Why do ordinary seamless steel pipes need to be pickled?

The iron oxide scale on the inner and outer surfaces of the hot-rolled tube stock or the in-process tube after the intermediate heat treatment should be removed before the cold working of the ordinary seamless tube. The existence of iron oxide scale, on the one hand, affects the quality of subsequent lubrication; on the other […]

A brief introduction to the production process of seamless steel pipes

It means that there is no weld on the steel pipe. This kind of steel pipe is integrally formed, and is directly rolled from a billet in the production. Because of the seamless relationship, it has a very good high pressure resistance advantage, and is often used as a boiler tube and a bearing tube. […]
