1, different bearing capacity:

Generally, the maximum service pressure that slotted pipe can bear is less than 20kg, which is the safest service range. It is usually used for low-pressure fluids such as water, gas and compressed air. Seamless pipe can withstand ultra-high pressure, of course, its wall thickness will also increase, which needs to be designed according to pressure requirements. It is generally used for high-temperature and high-pressure equipment such as high-pressure oil pipes and boiler tubes. There are seamless pipe fittings for structure, depending on the design requirements.

2. Different treatment forms:

Welded steel pipe parts and seamless steel pipe parts are divided into processing forms, generally welded steel pipe parts are formed; Seamless steel pipe parts have two ways: cold drawing and hot binding.

Stainless steel seamless pipe fitting is a kind of strip steel with hollow section and no seam around it. The thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, the higher the processing cost. The technology of this product determines its limited performance. Generally, the precision of seamless steel pipe parts is low: uneven wall thickness, low brightness inside and outside the pipe, high cost of length, and difficult removal of internal and external pits and black spots; Its detection and shaping must be done offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials.
