Core business
1. Valve Design and Customization
With the support of a professional technical team, we can provide customized services according to national standards or non-standard requirements for industries such as oil drilling, chemical engineering, and general machinery. The design process integrates multidisciplinary technologies including fluid dynamics and materials science, ensuring the sealing performance, pressure resistance, and service life of valves. Our product range includes various general-purpose valves, mechanical components, and matching sealing parts, meeting the complex operational demands in industrial production.

2 High-end Weld Overlay Technical Services
As a core competitive advantage, the company specializes in the field of metal surface treatment and heat treatment processing, with particular expertise in the thermal wire TIG surfacing technology for valves. The surfacing process strictly adheres to JB/T 6438—202X "Technical Requirements for Plasma Arc Surfacing of Valve Sealing Surfaces" and GB/T 22652 surfacing process qualification standards. High-quality materials such as cobalt-based, nickel-based, and iron-based stainless steels are selected to ensure the hardness, wear resistance, and corrosion resistance of the surfacing layer meet specifications. This surfacing technology significantly enhances the service life of valve sealing surfaces and is widely applied in severe operating conditions such as high temperature, high pressure, and strong corrosion, providing essential performance assurance for valve products.
