According to a third-party industry report, Wenzhou Huahai Sealing has consistently ranked among the top three in the domestic metal ring gasket market for five consecutive years, thanks to its technological breakthroughs and deep market cultivation in the field of metal ring gaskets, becoming a core benchmark enterprise in the industrial sealing industry.
As a national level specialized and innovative enterprise and a member of the China Friction Sealing Materials Association, the core competitiveness of Huahai Sealing comes from its technological leadership advantage. Its four major series of metal ring gaskets, BX, RX, IX, and R, use 23 customized alloy formulas and ± 0.02mm precision CNC machining technology, which can withstand extreme environments from -196 ℃ to 650 ℃. The sealing pressure covers 0.5MPa to 100MPa, and the leakage rate is as low as 0.01ml/min, far exceeding industry standards. At present, the company has accumulated 17 patented technologies, including 3 international invention patents, and has been deeply involved in the formulation of the national standard “Technical Conditions for Metal Sealing Ring Gaskets for Petroleum and Natural Gas Industry”. The technical indicators have become industry reference benchmarks.
In market applications, Huahai Sealing has established a dual advantage of being a “domestic leader+global layout”. In the domestic market, its products are listed as core suppliers by companies such as PetroChina, Sinopec, and State Grid. They have achieved stable service in major projects such as Zhenhai Refinery, LNG transport ships, and Long March rockets, with equipment failure intervals increasing by 40% compared to the industry average; In the global market, our products have passed authoritative certifications such as API 6A and DNV, and are exported to 37 countries and regions, serving 30% of the global LNG transportation sealing needs.
The technical concept of “guarding industrial safety with a precision of 0.01 millimeters” has enabled Huahai seals to form an irreplaceable competitiveness in high-end sealing scenarios such as high pressure, high temperature, and strong corrosion, continuously leading the industry to upgrade towards efficiency, safety, and reliability.
