seamless steel pipe between differences

seamless steel pipe between differences

Steel is the national construction and to achieve the four modernizations essential materials, widely used variety. Depending on the cross sectional shape, the steel is generally divided into four main categories of profiles, sheet, pipe and metal products. Among them, the pipe steel pipe, in our lives everywhere, and played a huge role.
Steel pipe used not only for the transmission fluid and powdered solid, the exchange of heat, the manufacture of mechanical parts and containers, it is an economical steel. Steel pipe manufacturing building grid structure, pillars and mechanical bracket, can not only reduce weight, save the metal 20 to 40 percent, but also to achieve the construction of factory mechanization. Many types of steel pipe, but we are here to say is the seamless steel pipe and seamless steel pipe.
Seamless steel pipe and seamless steel pipe, but one word, but they are still differentiated. Steel pipe seamless steel pipe with high quality coil reinspection after passing the slitting or coil automatic forming and welding, while computer-controlled fusion temperature, remove the steel pipe inner, outer burr, qualified non-destructive testing in rare oxidation of the atmosphere in the overall heated to 910 ℃ -950 ℃ degrees released, in addition to the scales by stretch reducing mill multi-pass rolling, so that the full uniform of steel pipes throughout the microstructure, grain state, geometrical dimensions and mechanical properties. Seamless steel pipe is widely used in power station boilers, petroleum, chemicals, machinery, shipbuilding, automotive and other various fields.
Seamless steel pipe is a hollow sections, peripheral joints round, square, rectangular steel. It is the ingot or solid tube perforation made of the capillary, and then dial made by the hot-rolled, cold rolled or cold. Seamless steel tubes with hollow cross-section, a large number of solid steel pipes, steel round bar used for conveying fluids compared to the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of the structure parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames, and the construction using steel scaffolding.
In the market, we have a common pipe such ways: longitudinally welded pipes, spiral welded pipe and seamless pipe, straight seam welded pipe and spiral welded pipe are very good identification of the difference between seamless pipe and seamless pipe needs from the following aspects:
1, the pipe is generally speaking are cut to length, and are generally 6 meters, 9 meters or 12 meters. Seamless steel pipe length is very small, because Length factory fare very much.
2, from the cross-section of the tube head, if there is rust, then dried him off to earn, if you look carefully will find the welding area.
If pickling look, the effect is even more apparent.
Mastered these points can help you will soon be seamless steel pipe and seamless steel tubes separate, but also allows you to learn more about their properties.
Seamless steel pipe and seamless steel pipe between the number of differences, they are the same, that is, play an important role in production and life of people. However, this same point on the one hand so that the steel pipe has become the darling of many industries, on the other hand, also makes steel pipe market competition is more intense.
But there is competition, there is pressure, pressure, there is power, power will be able to do better.
