What is difference between seamless steel pipe and seamed steel pipe？

1. Different processing technologies:
Seamless pipe is made of high quality carbon steel or alloy steel. The processing technology of seamless pipe is divided into cold drawing and hot rolling, and the seamed pipe is generally made by welding.

2. Different uses:
Seamless pipes are mainly used as pipes or structural parts for fluid transportation, mainly used in the mechanical industry, while slotted steel pipes are mainly used in the construction industry, such as water transportation, gas, compressed air and other low-pressure fluids. However, seamless steel pipes are used for pressure pipes.

3. Different prices:
Because of the complex manufacturing process of seamless steel pipe, the price is relatively expensive compared with the seam steel pipe. The seam steel pipe is mainly made of steel plate (steel strip) by secondary welding, which is cheap in fixing price and widely used.
