The asbestos-free gasket material is mainly composed of a variety of synthetic fibers, rubber elastomers and inorganic fillers. The material has high mechanical strength, low oil and water absorption, and has good compression resilience and sealing. It is a fully vulcanized gasket material. Various compressor gaskets for refrigeration industry, engine gaskets, pump valves and pipeline gaskets in shipbuilding industry, various gaskets for petrochemical pipelines and flanges.
High and medium pressure oil-resistant asbestos gasket is made of domestic and imported high and medium pressure oil-resistant asbestos board, which is mainly used for static sealing of industrial pipeline flanges such as ships, oil refining, and chemical industry.
The asbestos rubber sheet mat is made of vulcanized high-strength sealing plate and oil-resistant asbestos rubber sheet. The surface is non-stick, smooth and flat, with high strength, good compression resilience and strong torque retention. The asbestos rubber sheet mat is temperature-resistant, acid-alkali-resistant, and non-corrosive. It is an ideal sealing liner for air, oil, water and other media, which can prevent “three leaks” and avoid polluting the environment.
The condenser gasket is a sandwich inner gasket molded with high temperature asbestos cloth mixed with glue, and is covered with PTFE anti-corrosion film, which is the preferred seal for condenser sealing.

The metal winding pad is the gasket with the best resilience among the semi-metal bonding pads. It is made of V-shaped or W-shaped thin steel strips and various fillers alternately wound. Its structural density can be made according to different locking force requirements, and the inner and outer steel rings are used to control its maximum compression degree. The surface accuracy of the flange sealing surface contacted by the gasket is not high. It is especially suitable for occasions where the load is uneven, the bonding force is easy to relax, the temperature and pressure change periodically, and there is shock or vibration. It is the original static seal at the flange connection of valves, pumps, heat exchangers, towers, manholes, hand holes, etc. It is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace and other departments
Types of metal winding gaskets: basic metal winding pads, metal winding pads with outer rings, metal winding pads with inner rings, metal winding pads with inner and outer rings, heat exchangers (with ribs), special-shaped metal winding pads.
Flexible graphite composite gasket is made of precision cutting of high-strength graphite composite plate. Material: carbon steel, stainless steel 304, 316, etc.
Main use: high temperature, high pressure pipe flange sealing.
The flexible graphite composite gasket is composed of punching teeth or punching metal core plate and expanded graphite particles.
The flexible graphite packing ring is continuously wound with graphite paper and compressed into a mold. It has various excellent properties that a good sealing material should have. When used alone or in combination with other fillers, it is especially suitable for static sealing parts under high temperature and high pressure conditions. It can be safely used in all media except aqua regia and strong oxidizing acids.
