A client in a Southeast Asian municipal water supply project, facing issues such as foundation settlement, thermal expansion and contraction, and construction connection deviations in long-distance water transmission pipelines, and also concerned that the enormous axial thrust generated by pipeline operation could easily damage equipment such as pumps and valves, specifically sought to discuss the procurement of double-flange detachable joints with us.

Based on the project’s site conditions, pipeline pressure rating, and stringent acceptance standards for overseas projects, we leveraged our mature technical experience to develop a customized solution for our client. The product is manufactured using high-strength materials, with a thickened flange structure for enhanced pressure resistance. A well-designed expansion and contraction stroke effectively compensates for pipeline installation misalignment and temperature deformation. High-quality sealing components provide long-lasting leak protection, and multiple force transmission bolts evenly distribute the axial force in the pipeline, ensuring flexible pipeline expansion and contraction while effectively distributing equipment loads, providing comprehensive protection for pumps, valves, and the entire pipeline network for stable operation.

The entire production process strictly adheres to export quality standards, with rigorous control at every stage, from processing and welding assembly to finished product inspection. All products undergo individual hydrostatic testing and a full inspection of appearance and dimensions to ensure stable pressure resistance, smooth expansion and contraction, and leak-free sealing. Finished products are uniformly treated with rust prevention.

After the product arrived on site and was installed and put into operation, its stable and reliable operation perfectly solved various existing pipeline problems in the project, and it successfully passed the local project completion acceptance. Professional technical customization, rigorous quality control management, and one-stop supporting services have earned high recognition from overseas clients, establishing a long-term and stable cooperative relationship between the two parties.
