Analysis of the key features of the two types of stainless steel
There are two common stainless steel pipe fittings: butt-welded stainless steel pipe fittings and press-type stainless steel pipe fittings. Stainless steel pipe fittings are a kind of raw material that we see more often. According to different types, their use characteristics are also different. The following is a detailed analysis of the use characteristics of these two types of stainless steel pipe fittings.
1. Butt-welded stainless steel pipe fittings
Butt-welded stainless steel pipe fittings are pipe fittings where the stainless steel pipe and pipe fittings are wound along the HDPE hollow wall to make a circle of argon arc welding pipe fittings. Welding is usually required.
Outer diameter of pipe fitting socket u003d outer diameter of pipe.
Butt welding is usually used for welding of standard larger stainless steel piping systems.
2. Compression type pipe fittings (introduction: the method of preventing loose connection of threaded fasteners is summarized)
It has the characteristics of firm and safe connection, convenient construction, suitable embedded device, free of protection and renewal, and relatively superior economic efficiency.
The working principle of the compression fitting is to pierce the thin-walled stainless steel tube into the socket of the compression fitting, and use a special compression tool to lock the stainless steel tube in the fitting. The cross-sectional shape of the compression part is hexagonal. In addition, there is an O-ring seal between the stainless steel pipe and the pipe fittings, so that it has the characteristics of anti-leakage, anti-drawing, anti-sensation and high pressure resistance. Therefore, it is a more advanced connection in the direct drinking water system, the tap water system, the heating system, the steam system, the industrial oil pipe system and the industrial air pipe system. Suitable for connection of water, oil, gas and other pipelines.
