Through constant tests, Baodi continuously makes improvements based on the actual situation and has developed YH pressure welded composite water supply system connectors, and obtained national patent approval. This technology has aroused resonance in the industry.

In the similar compression products in some European countries and Japan, the pipe diameter is usually not more than DN50, the water service strength is below IMpa, the ultimate test water pressure strength is less than 5Mpa, and the pulling force strength is also less than 5Mpa. Therefore, Baodi breaks the shackle of conventional thinking and adopts stainless steel compression connection in DN15-DN50 and socket argon arc welding connection in DN65 according to the design of pipe pulling force and water limit pressure when the indentation depth of groove reaches T on the back wall. The “YH series” pipe fittings created with this technology have won national patent certification.

This combined way of connection makes the construction easier and the project safer, avoiding huge losses and unnecessary corrections due to water leakage in the later period.
