Products Details

Because stainless steel has many ideal properties required by building materials, it can be said to be unique in metals, and its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the most cost-effective materials selected by architects.


Thin wall stainless steel pipe, which was only produced and used in China in the late 1990s, is a new family emerging in the field of pipe materials. It has been widely used in building water supply and direct drinking water pipelines. Thin wall stainless steel pipe is durable and has been recognized by the engineering community, and relevant parties are starting from reducing the wall thickness and reducing the price, so as to facilitate further promotion. In particular, the price of small-diameter stainless steel pipe is not high, so the supporting connection method, the reliability and price of pipe fittings are the main factors determining its development. Domestic developers have independently developed connection technology and pipe fittings in Sichuan, Guangdong, Zhejiang, Jiangsu and other places, which is a promising pipe. The Ministry of construction and relevant departments also attach great importance to this new type of pipe. According to the notice on the promotion and application of "high diameter to wall ratio and high precision stainless steel medium and high pressure water supply pipes, supporting pipe fittings and special technology" issued by China technology market management promotion center and gksz [2001] No. 71 document, The popularization and application of thin-walled stainless steel pipe technology and product is of great significance to improve the grade of Chinese modern buildings and improve and ensure the water quality of water supply. At the same time, the Ministry of construction attaches great importance to the promotion and application of thin-walled stainless steel pipes《 The industry standard of thin wall stainless steel water pipe was issued and implemented in 2001. Relevant technical specifications and installation Atlas of pipeline engineering have been issued by the Ministry of construction and are being prepared by Tongji University. At present, there are professional manufacturers in Sichuan, Guangdong, Zhejiang, Jiangsu and other places to produce thin-walled stainless steel pipes, and the products have become mature. Therefore, the time for popularization and application has come. There are various connection modes of stainless steel pipes. The common types of pipe fittings are compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection. These connection modes have different application ranges according to their principles, but most of them are easy to install, firm and reliable. Most of the sealing ring or gasket materials used for connection are silicone rubber, nitrile rubber and EPDM that meet the requirements of national standards, which eliminates the worries of users.

Clamping connection steps

1. Pipe breaking: cut off the pipe according to the required length. When breaking the pipe, do not use too much force to prevent the pipe from being out of round. 2. Deburring: after the pipe is cut off, the burr shall be removed to avoid cutting the sealing ring. 3. Marking: in order to completely insert the steel pipe into the socket of the pipe fitting, the insertion length must be marked and drawn at the pipe end. 4. Assembly: the sealing ring shall be correctly installed in the U-groove of the pipe fitting, insert the pipe into the socket of the pipe fitting and wait for crimping. 5. Crimping: during crimping, the convex part of the pipe fitting is placed in the concave groove of the die, and the jaw is perpendicular to the pipe axis. 6. Inspection: after crimping, check the crimping size with a special gauge.


Stainless steel pipe is safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin wall of the pipe and the successful development of new reliable, simple and convenient connection methods make it have more irreplaceable advantages of other pipes. It will be more and more applied in engineering, more and more popular and promising.Stainless steel integrates performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world. With the implementation of China's reform and opening-up policy, the national economy has achieved rapid growth, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant national policies because of its corrosiveness. Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system. However, in many cases, stainless steel pipe has more advantages, especially the thin-walled stainless steel pipe with wall thickness of only 0.6 ~ 1.2mm. In high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first, it has the characteristics of safety, reliability, sanitation, environmental protection, economy and applicability. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with the best comprehensive performance of water supply system. It is also a very competitive water supply pipe, which will play an incomparable role in improving water quality and improving people's living standards. In the building water supply pipe system, because the galvanized steel pipe has ended the glorious history of one hundred years, various new plastic pipes and composite pipes have developed rapidly, but various pipes still have some deficiencies in varying degrees, which is far from fully meeting the needs of the water supply pipe system and the national requirements for drinking water and related water quality. Therefore, relevant experts predict that building water supply pipes will eventually return to the era of metal pipes. According to the application experience abroad, thin-walled stainless steel pipe is recognized as one of the pipes with the best comprehensive performance.
