Description

Sealed pipeline component

Technical Field

The present invention relates to a sealed pipe component.

Background

With the development of national economy and the improvement of the living standard of people, thin-wall stainless steel water pipes and stainless steel pipe fittings become a new trend for the development of domestic water supply pipeline systems.

The domestic thin-wall stainless steel water pipe is a novel pipe which is published only after the 90 s of the 20 th century, and has the characteristics of safety, sanitation, high strength, good corrosion resistance, firmness, durability, long service life, maintenance-free property, attractive appearance and the like, so that the stainless steel water pipe is developed vigorously and is widely applied to water supply and direct drinking pipelines of buildings.

The 2001 national science and technology department, the China technical market management promotion center, issues a notice about popularization and application of 'high-diameter wall ratio high-precision stainless steel medium and high-pressure water supply pipes, matched pipe fittings and special technology', gives full certainty to thin-wall stainless steel pipes, and considers that the popularization and application of the technology and products have important significance for improving the grade of modern buildings and improving and guaranteeing the quality of water supply.

The national quality supervision, inspection and quarantine bureau issued 7/10/2003 releases the series standards of GB/T19228.1, GB/T19228.2 and GB/T19228.3, and popularizes the stainless steel card pressure type pipeline system.

The CECS153-2003 building water supply thin-wall stainless steel pipeline engineering technical regulation is published by the Chinese engineering construction standardization association of 9.25.2003.

The stainless steel pipe is safe, reliable, sanitary, environment-friendly, economical and applicable, the pipeline is thinned, and a novel, reliable, simple and convenient connection method is successfully developed, so that the stainless steel pipe has the advantages that more other pipes cannot be replaced, the application in engineering is more and more, the use is more and more popular, and the prospect is good.

With the implementation of the national reform open policy, the national economy is rapidly increased, and a large number of urban residences, public buildings and tourism facilities are built, thereby providing new requirements for hot water supply and domestic water supply. Especially for water quality, people pay more and more attention to and demand for the water quality is continuously improved. The galvanized steel pipe is a common pipe which is easy to corrode and gradually exits from a historical stage under the influence of relevant national policies, and the plastic pipe, the composite pipe and the copper pipe form the common pipe of a pipeline system. However, in many cases, stainless steel pipes are more advantageous, and particularly, thin-walled stainless steel pipes with a wall thickness of only 0.6-1.2 mm have the characteristics of safety, reliability, sanitation, environmental protection, economy, applicability and the like in high-quality drinking water systems, hot water systems and water supply systems with safety and sanitation placed at the head. The pipe material has been proved by domestic and foreign engineering practice to be one of novel, energy-saving and environment-friendly pipe materials with the best comprehensive performance of a water supply system, is also a competitive water supply pipe material, and has incomparable effects on improving water quality and improving the living standard of people.

In the water supply pipe system of building, because the galvanized steel pipe has already finished the brilliant history for a century, various new plastic pipes and composite pipes are developed rapidly, but various pipes still have some defects to different degrees, and can not completely adapt to the requirements of water supply pipe system and national requirements for drinking water and related water quality. Thus, the expert concerned predicts: the construction water supply pipe will be finally restored to the age of the metal pipe. According to the application experience in foreign countries, thin-wall stainless steel pipes are considered as one of the pipes with the best comprehensive performance in metal pipes.

The thin-wall stainless steel pipe is durable, is acknowledged by the engineering industry, and starts from the aspects of reducing the wall thickness and the price in related aspects, so as to be beneficial to further popularization. In particular, the price of stainless steel pipes with small diameter is not so high that the reliability and price of the mating connecting method and pipe fittings are the main factors for determining the development. In China, developers in Sichuan, Guangdong, Zhejiang and Jiangsu have independently developed connection technology and pipe fittings, and the pipe fitting is a pipe with a good development prospect. The construction department and related departments attach great importance to the novel pipe, and according to the Chinese technical market management promotion center and the document of the Chinese city number [2001]71, the popularization and application of the thin-wall stainless steel pipe and the popularization and application of the technology and the product of the high-diameter-to-wall-ratio high-precision stainless steel medium and high-pressure water supply pipe, matched pipe fittings and special technology are informed, so that the popularization and application of the thin-wall stainless steel pipe and the product have important significance for improving the grade of modern buildings in China and improving and guaranteeing the water quality of water supply.

The existing stainless steel thin-wall pipeline has no reliable sealing fittings, most of plugs on the market are screw thread type sealing plugs, and the disassembly and the installation are very inconvenient.
