About Henan Honglong Pipeline Equipment Manufacturing Co., Ltd.

Henan Honglong Pipeline Equipment Manufacturing Co., Ltd. is a modern manufacturing enterprise dedicated to the research, development, production, and sales of pipeline compensation and sealing equipment. Leveraging the robust industrial foundation and convenient transportation network of the Central Plains region, the company has been deeply involved in the pipeline equipment sector for many years. With a market-oriented approach, advanced manufacturing processes, and a comprehensive service system, Honglong has emerged as a trusted partner for clients in the petrochemical, municipal water supply and drainage, power energy, and building HVAC industries. We offer reliable and cost-effective core solutions for various pipeline projects. Our product range includes rubber soft joints, double flange limiting expansion joints, bellows compensators, and a series of waterproof couplings: stainless steel waterproof couplings, rigid waterproof couplings, and flexible waterproof couplings. All products are produced in strict accordance with the GB/T 17456—2023 standard. We also offer customized earthquake-resistant and corrosion-resistant reinforced products for special scenarios such as high-speed rail tunnels and cross-sea bridges. The flexible waterproof couplings, with their multi-layer sealing structure, can withstand a pressure resistance of over 1.2MPa, making them the preferred choice for waterproof projects in underground utility tunnels and wastewater treatment plants. Our service philosophy is "whole-process empowerment, co-creating value." Honglong Pipeline is committed to the principle of "customer needs at the core, value creation through service," and has established a full-process service system covering pre-sales, in-sales, and after-sales services. Our vision is to deepen our presence in the pipeline field and contribute to industrial development. [View Details]
