In the industrial circulating water system, the flange connection shall be in contact with circulating water containing chloride ion and dissolved oxygen for a long time, and the seals shall have good corrosion resistance and aging resistance. The metal ring gasket of Huahai Seal is made of high-quality materials such as stainless steel, and is forged, heat-treated, and precision processed to adapt to a wide temperature range and higher pressure environments. As R-type standard ring gaskets, octagonal gaskets and elliptical gaskets are designed with a cross-section of regular octagonal or elliptical shapes, specifically designed to match flange sealing grooves. After installation, they can form a hard seal contact between metals and maintain stable sealing effect even under pressure and temperature fluctuations. Stainless steel has good resistance to chloride ion corrosion in circulating cooling water due to the addition of molybdenum element, and is suitable for flange sealing scenarios that come into long-term contact with water media.
In boiler feedwater and steam systems, seals need to withstand high temperature, high pressure, and steam erosion environments. The metal ring gasket of Huahai Seal, with its radial self tightening sealing characteristics, is more reliable in sealing under high temperature conditions, and is suitable for high-pressure steam systems in nuclear power and supercritical thermal power plants in the power industry. The RX and BX series high-pressure gaskets are designed specifically for extreme high-pressure conditions, meeting the sealing requirements of high-pressure pipeline flanges in industrial water systems.
In the field of municipal water supply and treatment, the anti-corrosion and service life of seals directly affect the operating costs of the pipeline network. Huahai sealing products can meet the flange connection sealing needs of sewage treatment, water supply pipelines and other scenarios. For water treatment pipeline systems that require frequent disassembly and cleaning, metal ring gaskets have the advantage of being reusable, which helps reduce maintenance costs.
The metal ring gasket products of Huahai Seal have been successfully applied to deepwater underwater oil production equipment, which requires long-term maintenance free operation and high technical requirements for sealing strength and material pressure bearing capacity under harsh conditions. The product has passed the technical verification of major national equipment, fully demonstrating its reliability in high-pressure water system environments.
In terms of quality control, Huahai Sealing strictly follows relevant standards in production, and the products meet the requirements of relevant standards. The company has passed the relevant quality management system and industry certification. We implement full process quality control from raw material selection to finished product testing, with complete production conditions and strict testing methods. The product has a wide temperature range and can adapt to various working conditions with pressure levels. It can be selected according to different water system working conditions.
