Made in China SS316 High Resistance Ptfe Lined Flexible Expansion Joint
Plumbing expansion joints are essential components in piping systems, designed to absorb thermal expansion, contraction, vibration and misalignment of pipes caused by temperature changes, fluid flow and external factors. Made of materials like EPDM rubber, stainless steel and PTFE, they feature flexible cores and standard end connections (flanged, threaded, slip-on) for easy installation, with reinforcement layers and limit rods for enhanced pressure resistance and service life. Widely used in residential, commercial and industrial plumbing (hot water lines, HVAC, process piping, sewage systems), they relieve mechanical stress on pipe walls, fittings and supports, preventing cracking, leakage and permanent system damage. Proper selection based on medium, temperature, pressure and movement type, along with standard installation and regular maintenance, ensures optimal performance, keeping piping systems leak-free, stable and durable for long-term operation.
Ptfe Lined Flexible Expansion Joint have the following characteristics:
Taking into account the advantages of this product, its service life greatly exceeds that of existing steam hoses. Long term use does not require replacement, greatly reducing usage costs, improving efficiency, and being economical and practical.
