API Coupling for Tubing and Casing Pipe
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...
Differences Between Electric Fusion Welding and Electric Resistance Welding
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...
Color Analysis of Galvanized Seamless Steel Pipes
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
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...
Analysis of Weld Seam Distance Adjustment for Seamless Steel Pipe
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...

Cautions for Installation and Use of Straight Seam Steel Pipes
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...
Method for Removing Oxidation Scale of Anti-corrosion SSAW Steel Pipe
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...
What Causes the Strength of the Oil Casing to Change
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,...
Comparison of Performance and Technical Indicators of ERW and SAW
(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...
