Advantages of stainless steel tube: 1.Health ring 2.Durability and all the advantages of durability.Keep the temperature good.Easy to use stainless steel

Development trend and new standard of stainless steel pipe fitting

Tube originated in Europe, and quickly with its comprehensive advantages, widely used, has been to Europe, the United States, Japan, South Korea, Taiwan and other developed countries and regions supply water, supply air.Strike first.

Domestic pay more and more attention to the jiangxi thread card set of sub health drinking water, safe water for non-standard stainless steel y-shaped three-way safe domestic water pipeline direct drinking water system transformation, gas, and heating transportation, with the development of national economy and the improvement of people's living standards, thin-walled stainless steel pipe joints has become a domestic water supply pipe xinjiang JieTou Road systems of domestic thin-walled stainless steel tube is a new kind of pipe material, in the late 1990 s, the development of non-standard stainless steel tee tee safety and health, has high strength, good corrosion resistance, strong, long service life, maintenance free, beautiful wait for a characteristic, is currently the stainless steel pipe.Strong momentum, a large number of applications in building water supply.Direct drinking water.From relevant aspects, it can be seen that the stainless steel clamp type pipe fitting and the connection of stainless steel pipe fitting with thin-walled stainless steel pipe have generated a new national standard, and the connection and construction specifications of these two products are the same.There are national standards.Stainless steel precision tube by the pipe standardization technical committee auxiliary thin-walled stainless steel tube and pipe connection standard drafting work conference, on behalf of the Chinese architecture design and research institute experts and some representatives of the stainless steel tube parts factory is GB/T91228.1 fitting > < not rusty steel press-fitting into type, GB/T91228.2 < > stainless steel pipe connection with thin-walled stainless steel tube.GB/T91228.3< stainless steel dongguan stainless steel joint clamping type pipe fitting is discussed with 3 national standards of 0-shaped sealing ring >, which meets the revision of relevant standards. It is agreed that the outer diameter series of more than 12 stainless steel pipes sold in the Chinese market should be unified into 2 basic standard sizes, and the wall thickness of the pipe should be unified into 1 basic size.Important dimensions of pipe joints are provided for uniform use in future card joints of different metal materials such as carbon steel, copper and stainless steel.In the drafting of national standard _ < > stainless steel tube and pipe connection and installation specifications are discussed, thin-walled stainless steel pipe fittings and pipe connection between all the three main connection way of non-standard copper joint (cassette, thread type, welding) is put forward specific installation requirements and specifications, with construction unit as a specification for construction, to related unit for national standard for inspection.Acceptance offers favorable conditions.Some experts attending the meeting are as follows: the revision of the new national standard for thin wall and the formulation of the national standard > for connection and installation specifications for stainless steel pipes and fittings make the product specifications for stainless steel pipes and fittings consistent with the installation specifications for pipes and fittings.This standard realizes the accurate butt joint, so far only complements the national class stainless steel tube product standard, has made up for the national class stainless steel tube fitting installation specification standard regret.End of stainless steel pipe for Chinese construction.Quasi-referenced history of irregularities;Standardization of construction pipelines with different metal pipes;
