With the development of the national economy and the improvement of people’s living standards, thin-walled stainless steel water pipes and stainless steel pipe fittings have become a new trend in the development of domestic water supply pipeline systems.
The domestic thin-walled stainless steel water pipe is a new type of pipe that came out in the late 1990s. Due to its safety, health, high strength, good corrosion resistance, ruggedness, long life, maintenance-free, and aesthetics, the current development of stainless steel water pipes is strong. Has been widely used in building water supply and drinking water pipes.
In 2001, the China Technology Market Management Promotion Center of the Ministry of Science and Technology issued a notice on the promotion and application of “high-diameter-wall-to-high-precision stainless steel medium and high pressure water supply pipes and supporting pipe fittings and special technologies”, giving full recognition to thin-walled stainless steel pipes. The promotion and application of this technology and products will be of great significance to improve the grade of modern buildings, improve and guarantee the quality of water supply.
What are the features of ss press fittings ?
The stainless steel press fitting is a connecting piece, which has the characteristics of reliable and safe connection, convenient and fast construction, suitable for embedded installation, maintenance-free updating, green health and environmental performance and relatively economical advantages.
1. Reliable and safe connection
The press fitting connection has high strength and good vibration resistance. The connection part is “dead” at one time, avoiding the possibility of loosening the “live joint”.
The working principle of press fittings is to insert a thin-walled stainless steel pipe into the socket of the press fitting, and use a special pressing tool to hold the stainless steel pipe in the pipe fitting. There are O-ring seals between the pipe fittings, which make it have the characteristics of anti-leakage, anti-pulling, anti-vibration and high pressure resistance. Therefore, it is a relatively advanced connector in direct drinking water system, tap water system, heating system, steam system, industrial oil pipe system and industrial gas pipe system.
Press fittings are made of stainless steel and can withstand 1.6MPa, which is suitable for non-corrosive or corrosive media such as oil, water and gas. other pipeline connections.
2. convenient and fast construction
Avoid on-site welding, threading or rolling groove operations, as long as the dedicated pressing tools are used, the press connection can be easily completed, saving time, labor and costs, and the high success rate of one installation.
The press fitting adopts the embedded installation method. Only the corresponding press tools can be used during the installation process. Unlike the previous connection parts, it requires a lot of welding to connect. And more efficient and safer construction.
3. Low price and maintenance-free update
The press fitting is made of stainless steel and has good corrosion resistance. It can be maintained for several years after being connected, and it does not need to be replaced or repaired. Long life, no need to replace or repair the pipeline system during use, saving costs and low losses.
4. Green health and environmental performance
Over the past around 70 years, 5 different press fitting materials have gradually been applied to the production.
Stainless steel material is a well-known health material that can be implanted into the human body. It can meet the national sanitary standards for direct drinking water and can be 100% recycled.
The press fitting are all made of 316L stainless steel, and the O-ring is made of ethylene propylene rubber, chlorinated butyl rubber, nitrile rubber or silicone rubber, which has good sanitary and environmental performance and long service life.
