Spiral welded steel pipe refers to a steel pipe or steel plate that is bent and deformed into a circular, square, and other shapes, and then welded with a seam on the surface. Welded steel pipes are used in oil drilling and machinery manufacturing. Furnac
The deformed steel tube cant be placed directly on the ground. The surface of the steel bar that is in contact with the ground will stick to the soil. If it rains, the rainwater will not drain out, and the steel will rust after a long time. The following
First, the production method of seamless steel pipe: Hot rolled seamless steel pipe Hot rolled seamless pipes are generally produced on automatic rolling mills. The solid tube blank is inspected and the surface defects are removed, cut into the required l
When the technical condition of the automobile transmission shaft deteriorates, the amplitude of the bending vibration increases, the vibration is severe, and even the body is shaken, and an obvious periodic sound is emitted, which is called vibration and
The seamless steel pipe is formed by perforating a steel ingot or a solid tube blank, and then hot rolled, cold rolled or cold drawn. The specifications of the seamless pipe are expressed by the outer diameter X wall thickness and millimeter number. Sea
