With the continuous development of China's construction industry, the technical level has also been greatly improved. In recent years, even some second- and third-tier cities have been able to build more complex structures. Due to China's continuously increasing population, in order to meet more housing needs on limited land, improvements must be made in construction to provide the necessary housing for people, so that society can develop better. Steel pipes are indispensable in the construction industry and provide material support for more challenging construction projects.
With the continuous development of China's construction industry, the technological level has also been significantly improved. In recent years, even some second- and third-tier cities have been able to construct relatively complex structures. Due to China's continuously increasing population, in order to meet more housing demands on limited land, improvements must be made in construction to provide the necessary housing for people, so that society can develop better. Steel pipes are indispensable in the construction industry and provide material support for more challenging construction projects.
So what should be noted when using a welding pipe unit to produce oil casing? When producing oil casing with a welding pipe unit, the toughness should be considered. The welding pipe unit can improve the weld by controlling the cooling after hot tension reduction, which can greatly improve the weld of the welded oil casing and enhance its toughness. The chemical composition of the welding base material, welding temperature, and welding speed are the main factors affecting weld gray spots. To avoid weld gray spots, the quality of the strip edge and the welding process must be strictly controlled. Methods such as weld heat treatment and full-pipe heating before hot tension reduction can be used to reduce and avoid the appearance of weld gray spots. The control of groove-like corrosion of the weld requires hot tension reduction.
This equipment is commonly used in daily production, and using a welding pipe unit to produce oil casing has become a trend, which is mainly inseparable from the advantages of the welding pipe unit. Generally speaking, oil casing can be produced using hot-rolled seamless steel pipes, or it can be produced by welding with a welding pipe unit. The welding method using a welding pipe unit is more common in daily life. Because welded oil casing has a weld, problems such as matching toughness between the base material and the weld, weld gray spots, and groove-like corrosion of the weld need to be addressed. When welding oil casing, care should be taken to avoid these problems.
