With the development of oil weather, it has gradually developed to remote areas, oceans, and cold regions. The reliability of steel pipes for oil and gas pipelines has been increasingly demanded...

With the continuous improvement of the pipe material technical indicators in the market, the technical level of the existing seamless steel pipe production process can no longer meet the requirements...

The high-frequency resistance welding technology that directly rolls the steel material is a technique for rapidly producing pipes. At present, it is widely used in many fields such as underground...

There are many factors that affect the pulling force of stainless steel pipe during the drawing process. According to the results of many scientific workers and actual production operators, some of...

1. Position of the sensorThe placement of the inductor of the erw steel pipe (distance from the center line of the pressing roll) has a great influence on the quality of the welding. When it is far...

The high-frequency erw steel pipe mainly utilizes the skin effect and the proximity effect of the high-frequency current, so that the current is highly concentrated on the edge to be welded, so that...

1. Regulation of the status of high frequency induction coilThe useful heating time is long, and the high frequency induction coil should be as close as possible to the position of the squeeze roller...

High-pressure seamless steel pipes for pseudo-deterioration equipment usually have the following characteristics:1. The pseudo-deteriorating fertilizer device is easy to fold with a high-pressure...

The seamless steel pipe is made of steel ingot or solid tube blank through perforation and then made by hot rolling, cold rolling or cold drawing. 45 seamless steel pipe is a kind of material in...

The Challenge of Energy Saving and Green Building for Thick-walled Steel Pipe BuildingsAt present, the development of green buildings still faces some difficulties, such as the constraints of...

The carbon steel pipe is closely related to human life and production activities. The production technology of the steel pipe industry not only develops rapidly, but also introduces new ones. Steel...

If the double-sided ssaw steel pipe is rusted, the steel surface is mainly polished using tools such as a wire brush. The cleaning and preheating of the spiral pipe can remove the loosened or tilted...

The edge of the erw steel pipe blank is heated and pressed and butted together to form a weld seam. In this process, the high-frequency current with skin effect and proximity effect is highly...

Resistance welding As the name suggests, resistance welding is a method in which a weld is combined and pressure is applied through an electrode, and the current is passed through the contact surface...

What is a spiral submerged arc pipe? I believe that many people are not very familiar with it. In short, this is actually a process of processing a tube blank with a low-carbon steel strip or a...
