Gongyi Hongsheng Water Supply and Drainage Materials Co., Ltd. Has been deeply engaged in the field of pipeline accessories for many years. With a wealth of industry experience, we have continuously grown and developed, gradually establishing a solid position in the domestic market. Our business scope covers a wide range of pipeline - related products. We are specialized in manufacturing various rubber joints, such as the JGD(KXT) flexible rubber joint, double - sphere rubber joint, and lined tetrafluoroethylene rubber joint which is resistant to strong acids and alkalis. These rubber joints are widely used in water supply and drainage systems, industrial pipelines, and HVAC systems, effectively compensating for pipeline displacement, reducing vibration, and preventing leakage. In addition to rubber joints, we also produce a variety of expansion joints, including rotary sleeve expansion joints, QB - type spherical expansion joints, and flange - type loose - sleeve expansion joints. These expansion joints play a crucial role in pipeline systems by absorbing thermal expansion and contraction, ensuring the safe and stable operation of pipelines. Our product line also includes waterproof sleeves, such as 02S404 flexible waterproof sleeves and 02S404 national standard rigid waterproof sleeves. These waterproof sleeves are essential for preventing water leakage in building structures and underground pipelines. Moreover, we manufacture shock absorbers like ZTF adjustable damping spring shock absorbers, ZD horizontal damping spring shock absorbers, and XHS suspended damping spring shock absorbers, which are used to reduce vibration and noise in pipelines and equipment. Over the years, we have accumulated rich experience in product manufacturing and quality control. Our products have passed strict quality inspections and have been well - received by domestic customers. We have completed numerous projects in different regions, providing high - quality products and professional services, and winning a good reputation in the industry. Looking ahead, with the continuous development of the global economy and the increasing demand for infrastructure construction, we see great potential in the international market. We are committed to expanding our overseas business. We will continue to adhere to the principle of "quality first, customer first", constantly improve product quality and performance, and provide more comprehensive and professional services. We aim to become a well - known brand in the international pipeline accessories market, and contribute to the global infrastructure construction with high - quality products.
