the differences of welded steel pipes and seamless steel pipes

How much do you know about steel pipe?  Generally, steel pipe is a building materials made from alloy of iron and carbon. So it can not only be used in the construction industry but also in a variety of manufacturing and industrial lines widely. In the pipeline systems, steel pipe is used to transport liquids, oil, natural gas and gas for commercial and residential buildings as well as in municipal water supply. Of course, the steel pipe also acts as a structural component for scaffolding and framing systems.

Welded Steel Pipes and Seamless Steel Pipes

Because of different processing technology, steel pipe can be divided into seamless steel pipes and welded steel pipes. Seamless steel pipes are made from a piercing rod, which gives the material a smooth and even without joints, but are much more expensive in prices considering more reliable, especially in high pressure applications. The seamless steel pipe includes high quality carbon steel pipe and alloy steel pipe, which consists of two types of hot and cold drawn. Carbon steel pipe is widely applied in relative affordable, which is popular choice for large projects like oil and natural gas pipelines. While alloy steel pipe is a one of the much dearer types of pipes on the market with high level of corrosion-resistance, which allows smaller and thinner pipes to be used.

However, welded steel pipes is made from steel sheets which are rolled around a form, then with butt or spiral seam welded together along the joints and are less expensive than seamless steel pipe in prices. But welded steel pipe can not hold up well in high pressure applications generally. In the manufacturing ways, it can be divided into low pressure fluid delivery ERW pipe, SSAW pipe and LSAW pipe etc. Welded steel pipes can be used for water pipes, gas pipes, heating pipes etc. Since steel pipe has become so common and indispensable, it is also a considerable amount of market demand.
