Seamless Steel Pipes VS Seam Steel Pipes.
What are the differences between them?
Seamless steel pipes can be used to transport fluid (such as natural gas, oil, water, etc.), some solid materials, etc. It is a kind of economic steel. The cost can be reduced by using steel pipes to make the grid, support and mechanical support of building structure. Today, we collect and sort out the differences between seamless steel pipes and seam steel pipes for knowledge sharing.
1. Processing technology.
The seamless steel pipe is made of high quality carbon steel or alloy steel. The processing technology of seamless steel pipes can be divided into the cold drawing method and hot rolling method, and seam steel pipes are generally welded.
2. Usage. The seamless steel pipe is mainly used for conveying fluid pipeline or structural parts. It is mainly used in the mechanical industry. The Seam steel pipe is mainly used for fluid and gas transportation in the construction industry, such as water, gas, compressed air and other low-pressure fluids. Generally, seamless steel pipes will be used in pressure pipes.
3. Under normal circumstances, the use pressure of seam steel pipes can be under 20 kg, which is the safe usage range. It is usually used for water, gas, compressed air and other low-pressure fluids. Seamless pipes can withstand super high pressure. Of course, the wall thickness will increase, which needs to be designed according to the required pressure. It is often used in high-pressure tubing, boiler pipes and other high temperature and high pressure equipment. There are also seamless pipes for the structure. It depends on the design requirements.
At present, there are several kinds of seamless processing for seam steel pipes, and the welding seam is annealed. The pressure range is basically equal to that of seamless steel pipes. You could consider using it. There are also some seam steel pipes on the market using integral heating and then it will be pulled or core head rolled into seamless steel pipes. The specifications are smaller. This kind of steel pipe is seamless steel pipe only in appearance. Its essence is not very ideal.
4. Uses. The seamless steel pipe is made by cold drawing and hot drawing. In general, the medium pressure is equal to or greater than 1.6MPa. The seam steel pipe is made of steel plates after forming with butt high frequency welding. It is suitable for medium pressure less than 1.6MPa.
