Comply with the Work Safety Law! Take on the role of the primary responsible person! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. China’s chemical equipment sector has also seen significant progress, which has contributed to the swift development of the petrochemical industry. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. We welcome everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical equipment! ------------------------------------------------------ Your participation is the greatest support for the forum.

These valves include ROV-driven ball valves and gate valves; they are designed for depths of 500 meters, with a maximum design pressure of 26 MPa and a maximum diameter of 10 inches. They will be used in the South China Sea for an extended period of time. The designed service life of these underwater valves is 20 years. The valve body is made of carbon steel with a full weld-on nickel-based alloy coating; the internal components are made from special nickel-based alloys. The shell features a fully welded structure, and the internal sealing mechanism consists of multiple metal seals. Through precise manufacturing processes and individual leak testing for each seal, all valves in this batch achieved zero leakage levels, which far exceeds the requirements of ISO 5208 Class C (in fact, they meet ISO 5208 Class A standards). This ensures that the valves can operate stably throughout their entire service life without the need for maintenance. Furthermore, the drive units and diver’s handwheel operating devices equipped in these underwater valves are all Newway patented products, developed and manufactured by the company itself. This breaks the monopoly held by European and American brands in the field of drive mechanisms for underwater use, indicating that Newway now possesses the capability to independently develop and supply complete sets of underwater valves and drivers.
