The casing pipe coupling is a kind of oilfield drilling tool, which is mainly used for the connection of the oil pipe, and mainly solves the problem that the existing coupling easily generates fatigue...

Electric fusion welding is the joining of metals by heating the metal between one or several consumable electrodes and the workpiece.Electric resistance welding is a welding that uses a strong current...

Galvanized seamless steel pipes have very little galvanizing, only 10-50g/m2, and their corrosion resistance is much worse than that of hot-dip galvanized pipes. Regular galvanized pipe manufacturers ...

Oil casing pipe gas seal detection technology principle and process Principle: The tightness of the oil casing buckle is closely related to the pressure and medium. The pressure and medium molecular s...

In the processing of seamless steel pipes, there is often a problem that cannot be ignored, which is the weld seam. In order to ensure the performance of seamless steel pipes, we need to take some mea...

Production process of oil casing pipe Cold drawing: Tube billet - inspection - shearing - heating - hot perforation - heading - capillary tube storage - pickling, phosphating, saponification - cold d...

Straight seam steel pipe is widely used in various industries, such as petroleum, metallurgy, construction, coal mine, port, machinery and other industries. During the installation and use of straight...

Removal methods of anti-corrosion ssaw steel pipe include mechanical method, chemical method and electrochemical method. Due to the complexity of the scale composition of the anti-corrosion spiral ste...

The strength and quality of the oil casing pipe is always a concern for everyone, because the quality of the oil casing is one of the important factors affecting China's crude oil production. In fact,...

(1) Since the length of the SAW weld is approximately 4-5 times the length of the ERW weld, the internal welding knob has no process ability to remove it, so the friction of the inner wall of the pipe...
