The hollow wall joints supplied by this manufacturer are processed with special materials suitable for hollow wall pipelines. The core is the connection design between the outer wall and the inner wall structure of the hollow wall pipeline. The pipeline is tightly docked through the sealing ring or socket structure, which can not only adapt to the lightweight characteristics of the hollow wall pipeline, but also ensure the sealing and pressure bearing of the joint, and avoid the leakage of the conveying medium. Its material is resistant to acid and alkali corrosion, and has stable performance in the temperature range of -10 ° C to 60 ° C. It is not easy to age and deform at room temperature. It is suitable for the connection of the hollow wall drain pipe and the water supply pipe. It is the core accessory of the installation of the hollow wall pipeline system. In terms of specifications and models, hollow wall joints cover DN110 to DN600 commonly used nominal diameters, which are accurately matched with hollow wall pipes of the same specification: DN110-DN200 small diameter is suitable for community branch pipes and courtyard pipeline connections, DN225-DN400 diameter is suitable for municipal branch pipes and commercial complex pipelines docking, DN450-DN600 large diameter is suitable for industrial park trunk pipes and municipal pipe network connections; manufacturers support the deployment of calibers according to wholesale orders, and can also provide supporting sealing rubber rings to improve connection reliability. The product has a wide range of usage scenarios and is suitable for residential community hollow wall drain pipe connections, municipal road hollow wall water supply pipe docking, commercial complex drainage pipe splicing, industrial park hollow wall wastewater pipe installation, rural sewage treatment hollow wall pipe connections, etc. It is suitable for outdoor burial, pipe trench laying and other installation methods. At present, the manufacturer supports wholesale, and the price has advantages.
