What is the difference between welded steel pipe and seamless steel pipe for stainless steel pipe fittings

1. Different pressure bearing capacity:
The working pressure that the seamless steel pipe can generally withstand is within 20 kg, which is the safest use range. It is generally used for low-pressure fluids such as water, gas, and compressed air; seamless steel pipes can withstand ultra-high pressure, and of course their wall thickness will increase accordingly, which needs to be designed according to pressure requirements. It is generally used in high-temperature and high-pressure equipment such as high-pressure oil pipes and boiler pipes. There are also seamless pipes for structural use, which depends on the design requirements.

2. Different processing forms:
Welded steel pipes and seamless steel pipes are divided according to the processing form. Welded steel pipes are generally welded; seamless steel pipes are cold-drawn and hot-rolled.
