The Technological Development of Welded Steel Pipe

Nearly all pipe making involves the welding process. The techniques in dealing with this procedure in most cases determine the difference between a hack job and good craftsmanship. The steels used in the making of welded steel pipe are far more sophisticated than those in the 1980s and 1990s. More kinds of steel alloys marked with outstanding physical and chemical properties have been invented and applied in a whole range of projects. For example, a stainless steel alloy is primarily made of iron with a substantial amount of chromium and nickel added during the alloying process. The most notable type of corrosion-resistant stainless steel alloy is widely used by architects to be applied in environments with high moisture. In addition, the heat treatments and the melting process have been dramatically upgraded. Thanks to the technological development of welded steel pipe, steel pipe manufacturers are capable of creating development welded steel pipes that are precisely crafted to meet customers' demands.

There are various kinds of welded steel pipes. ERW steel pipes are generally cold formed and can be made by the means of spot welding and seam welding in a variety of lengths and thickness. As a matter of fact, both methods involve the use of electrical energies to hold the melting steel together, hence the name of ERW steel pipes. Besides, such factors as the heating temperatures, the chemical compositions of electrode geometry, and the physical properties of the steel all have certain influence on the welding results. Thanks to the versatility of the ERW steel pipes, they are widely used in the underground piping projects and you may also find ERW steel pipes in such places as warehouses and hospitals.

On the other hand, in comparison with ERW steel pipes, fusion welded steel pipes have different manufacturing methods and applications. Generally speaking, fusion welded steel pipes are often used to transport fluids such as water in agricultural projects and chemical plants. Made of coiled steel that is joined one after another, fusion welded steel pipes are sent into a furnace to get welded. The good news is that fusion welded steel pipes can be manufactured from the mixture of steel alloy and a wide range of less expensive metals, depending on the customers' requirements. What is more, marked with appealing aesthetic features, spiral welded steel pipes are frequently used in construction projects to add to the geometric styles of the buildings. And it is relatively easy to install spiral welded steel pipes because thanks to the curvy shapes, less joints and hangers are needed in the installation. Moreover, with a smooth interior, the LSAW steel pipe can also be used to transport gas or fluids as the special shape can helps reduce leakage and relieve the pressure on the pipe walls. In chemical production practice, spiral welded steel pipes not only helps to reduce the amount of toxic pollutants but also collects the useful byproducts.
