1, single compression: D compression connection. The earliest pressure welding technology of thin-walled stainless steel in China.
Features: O-ring (line seal) and hexagonal locking structure.
2. Double clamping: An improved S-shaped clamping connection technology based on single clamping.
Features: Compared with single bayonet, it has an extended edge.
3. Ring compression: it is the improvement and development of compression foundation.
Features:
O-ring is changed into broadband sealing ring (elastic line sealing is changed into filling sealing), and hexagonal deformation is changed into annular locking structure, which improves sealing reliability and bearing capacity.
1. Ring pressure connection requires low matching accuracy of pipes and fittings due to the filling seal. The annular pressure stainless steel pipe fittings can adapt to the pipeline with large tolerance, so in practical application, because the pipeline is small, the leakage at the annular pressure joint is very small.
2. Ring pressure connection adopts ring locking structure, which improves the bearing capacity. After a long-term trial, the rated working pressure of stainless steel pipe fittings in GB33926 can reach 2.5MPa, which is the only product that can be used for 2.5MPa in domestic extrusion connection methods.
The two new joints are perfect clamping connections, with a wide connection range, which are suitable for the working environment from -50℃ to 150℃, and are used to connect various pipes with diameters of dn 15-dn 150.
Snap ring connection
The snap ring connecting pipeline organically combines mechanical connection and adhesive connection. Give full play to the characteristics of anaerobic adhesive, no longer rely on rubber ring sealing, make up for the shortcomings of traditional clamping,
Thin-walled stainless steel pipes bonded together have the advantages of good circumferential rotation resistance, good sealing performance, high connection strength, simple construction and convenient operation, which greatly saves the pipe cost and installation time. It is the most ideal way to connect stainless steel pipes at present.
Double ring compression connection
The "double-ring crimping" mode of stainless steel water pipe is a national patent product and a new connection mode. It is a re-optimized structure on the basis of annular pressure pipe fittings, and the size of the sealing sleeve is increased. On the basis of the original annular pressure, two sealing surfaces are added, with a total of ***4 sealing surfaces, so as to avoid the phenomenon of empty drum in the sealing section, improve the sealing performance and prevent leakage.
In the process of pressing with special tools, the tools are evenly pressed inward along the outer edge of the sealing section of stainless steel water pipes, and the scientific compression ratio is calculated according to the thickness of different rubber sealing rings, that is, sealing bags, so that the products can be molded at one time, with high tensile strength and good sealing performance, and the products are more scientific, firm and durable.
At present, double-ring crimping and snap ring bonding are patented products of Juyuan. Because of its unique advantages, it is rare in the market. I hope my answer can help you.
