Read MoreSelection criteria for high frequency welded pipe (ERW) welding consumables Classification of welding rods: (1) Classification by slag properties Welding electrodes can be divided into two categories: acid electrodes and alkaline electrodes. The electrode whose slag is mainly acid oxide is called acid electrode. The electrode whose slag is mainly alkaline oxide and calcium fluoride is called alkaline electrode….
Read MoreWhat is an oil casing coupling? Oil casing coupling is a kind of oilfield drilling tool, mainly used for the connection of oil pipes. The oil casing coupling mainly solves the problem that the existing coupling is prone to fatigue and fracture due to stress concentration. The coupling structure of the oil casing is: the end of the oil…

Faucet with pipe for agricultural irrigation and pipe for sprinkler irrigation, etc. 2. Pipes for thermal equipment. Such as boiling water pipes and superheated steam pipes for general boilers, superheated pipes, large smoke pipes,…
Read MoreFor the defects of seamless steel pipes, magnetic flux leakage detection method, ultrasonic detection method, eddy current flaw detection method, etc. can be used. 1. Magnetic flux leakage detection method The magnetic flux leakage detection method is to use the magnetic flux leakage principle to detect the seamless steel pipe. During the inspection process, the inspected seamless steel pipe…
Read MoreAnalysis of the causes of common defects in seamless steel pipes: (1) Reasons for the irregular distribution of folding defects. Improper viscosity of mold slag, obvious abnormality of molten steel vortex or abnormal vibration frequency of mold will cause slag entrainment. Most of the mold slag exists in the subcutaneous or surface area of the continuous casting billet, so…
Read MoreCommon defects of seamless steel pipes can be divided into two categories: external surface defects and internal surface defects. 1. External surface defects (1) Folding defects are irregularly distributed. Macroscopic features: If there is mold residue left on the surface of the continuous casting billet, the outer surface of the rolled tube will have deep folds.There are stacking defects,…
