Audited Supplier
Expansion joint pipe fittings is composed of inner and outer rubber layers, curtain layers, and steel wire rings, which are vulcanized and then loosely combined with metal flanges or parallel joints. The double ball design improves the air tightness and waterproof performance of the product, while effectively extending its service life and reducing noise. Its unique double-layer sealing structure achieves good water tightness and air tightness, making it have excellent sealing performance.

The production process of expansion joint pipe fittings:
| 1.Raw material Top level CR/EPDM/NBR rubber raw materials,No recycled rubber | 2.Plasticating and mixing Special Formulation for better Bending with Nylon,For Better Strength,Sealing | 3.Workblanks wraping Cooper plated steel wire reinforcement prevent pull off |
| 4.Vulcanizing Automatic vulcanization machine ensure vulcanization time and pressure | 5.Inspecting 100% strict inspection is to be responsible for consumers | 6.Packaging Protective Packaging for No Rust and Breakage |
Expansion joint pipe fittings have good pressure resistance, wear resistance, corrosion resistance, and seismic performance, which can absorb the vibration and displacement generated by pipelines during operation, protecting pipelines and equipment from damage. Double ball rubber joints are widely used in pipeline systems such as petrochemicals, heating, air conditioning, water supply, and drainage.
