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 spiral
welded steel pipes 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.
