Difference between seamless steel pipe and slotted steel pipe

　　The difference between seamless steel pipe and slotted pipe is that they are used for different purposes: seamless steel pipe is mainly used for conveying fluid pipes or structural parts, mainly used in machinery industry, while slotted steel pipe is mainly used in construction industry, such as water supply, gas, compressed air and other low-pressure fluids. However, seamless steel pipes are used for pressure pipes.

　　Generally, slotted pipes can withstand a large pressure of less than 20 kg, which is a safe range of use. It is generally used for water, gas, compressed air and other low-pressure fluid;

　　Seamless steel pipe can withstand ultra-high pressure, of course, its wall thickness will also increase, which needs to be designed according to the pressure requirements. It is generally used for high-pressure oil pipes, boiler pipes and other high-temperature and high-pressure equipment. There are also seamless steel pipes for structure, which depends on the design requirements.
