The laying of each heating pipeline is an extension of the city's arteries, and a solid force for warming thousands of households and ensuring industrial development. At a key heating project site in western China, Lianggu Valve Group once again delivered a large batch of ultra-large diameter DN1600 fully welded pipes on schedule.Ball valves embark on a mission that concerns the well-being of hundreds of thousands of users.
Extra-large caliber, witnessing the strength of a great nation's craftsmen
Lianggu Valve Group in ultra-large diameter fully weldedWith over thirty years of experience and mature technology in the ball valve manufacturing field, we consistently provide high-quality products and services for various major engineering projects. From rigorous raw material selection and forging to precision cutting and assembly using large CNC equipment, and then to automated welding and full-process testing, every step is meticulously controlled, and every process reflects our commitment to quality and responsibility. Relying on advanced manufacturing equipment and standardized production processes, we elevate precision to even higher standards, ensuring the valves are structurally sound, reliably sealed, and capable of withstanding the test of long-distance, high-pressure operation.
For long-distance pipelines, "zero leakage" is the bottom line. Lianggu DN1600 fully welded...Ball valves feature a seamless welded body to the pipeline, completely eliminating any potential leakage risks caused by bolt fatigue or aging. Each valve undergoes rigorous performance testing on a large testing platform before leaving the factory, ensuring long-term stable operation under extreme conditions and providing peace of mind for urban centralized heating and industrial heat transmission.
Lianggu extra-large diameter fully weldedBall valves not only boast a long lifespan and minimal maintenance, but are also equipped with intelligent drive systems for remote automatic opening and closing regulation, perfectly matching the current trend of smart energy and intelligent pipeline networks. Each valve is precisely manufactured to the standard of decades of trouble-free operation, significantly reducing operation and maintenance costs for projects and realizing the value of "maintenance-free and long lifespan" in every kilometer of pipeline.
As a backbone of China's valve industry, Lianggu Valve Group has served key national projects for many consecutive years—from the West-East Gas Pipeline to multi-million-ton projects in nuclear power, heating, and petrochemical fields. With a spirit of craftsmanship that surpasses itself, we consistently strive to reach the pinnacle of valve manufacturing. We are a designated supplier for numerous central enterprises, state-owned enterprises, and large energy groups; a co-creator of industry standards; and a warm guardian for millions of users.
In the future, Liangu will continue to innovate, join hands with more customers, and become a model integrated solution provider for the valve industry.
