Since 1960s and 1970s, many developed countries began to use stainless steel pipes in drinking water treatment and distribution systems. Stainless steel water pipes have gradually become the new choice of water supply pipes and become the current world trend and development direction.
The connection of stainless steel water pipes has developed from the initial welding connection to the current hoop connection, clamping connection and today's "double ring pressure connection", and the connection of stainless steel water pipes has become more convenient, fast, simple and efficient.
The "double-ring crimping" mode of stainless steel water pipe is a national patent product, which is a re-optimized structure based on ring crimping pipe fittings. The size of the sealing sleeve is increased, and two sealing surfaces are added on the basis of the original ring crimping, with a total of ***4 sealing surfaces, which avoids the empty drum phenomenon of the sealing section, improves the sealing performance and prevents 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.
