Seamless steel pipe is a hollow structure without joints and seams. When it comes to the welded steel pipe, sometimes it can function as same as the seamless pipes. Nevertheless, their properties are definitely different. The simple method to tell welded pipe from seamless pipe is to inspecting the color - welded pipe is black in most situation while the seamless pipe is grey or white.

Seamless pipe is endowed with property that other pipes can not catch up. Its seamless feature make is suitable for the conveying of flammable oil, gas and water. In addition, it is able to be used to transfer some solid materials. Take the torsional strength into consideration, it is an economic option. Its mechanical property helps it win a place in automobile industry and other heavy industries.

The design of different shaped pipes confirms to various design concept. For example, the annular pipes have the ability to convey more liquids as compared with square frames. It is estimated that the circle gain the opportunity to create largest areas with same circumference. Thereby, annular pipes can reduce the product expense. At the same time, the pressure from both internal and external side can be evenly distributed at the surface of annular pipes. Thereby, the round pipes are considered to endure higher pressure as compared with pipes in other shapes. But in some situations, the rectangular pipes are favored.

The pressure level of seamless steel pipe consists of nominal pressure and thickness of the wall. There is no doubt that the thicker pipes have higher resistance to pressure. Before designing the pipes, the pressure level should be predetermined and it should be the core of design. According to the pressure grade, it is possible to arrange the pipes properly at the right position. In order to purchase high quality welded steel pipe, you need to choose the reputable manufacturers.
