As a leading manufacturer from Shanghai Zhibang Valve Manufacture Co., Ltd (established in 2016), we are proud to introduce our GB/T12465-2007 Expansion Joint — a high-performance solution designed to absorb thermal expansion, vibration, and misalignment in piping systems. Each unit is supplied with a Mill Test Report (MTR) and a comprehensive Warranty, ensuring full traceability and reliability. Our products are exported to over 15 countries and regions, with an annual export value of US$1-1.5 million, backed by our ISO9001:2015 certified quality management system.
This expansion joint strictly follows the Chinese national standard GB/T12465-2007, which specifies the design, material, and testing requirements for bellows-type expansion joints. Whether you need to compensate for axial, lateral, or angular movement, our product offers flexible configurations to meet your specific piping requirements. Available in a wide range of materials (SS304, SS316L, carbon steel, etc.) and sizes from DN50 to DN4000, we can customize the joint to your project.
Why choose our GB/T12465-2007 Expansion Joint? Because we combine strict quality control, complete documentation, and strong after-sales support. Every unit undergoes hydrostatic and leak testing, and the Mill Test Report confirms the chemical and mechanical properties of the materials used. The standard warranty period is 12 months, and extended coverage is available upon request.
