Alloy (Incoloy800), the material specified by the customer can also be used.
High temperature resistant metal spiral wound gasket HLSW hot series
HLSW hot series of high temperature resistant metal spiral wound gaskets are special metal spiral wound gaskets developed by Hengli Sealing to solve flange sealing in high temperature (≤1000°C) occasions.
Low-performance high-efficiency sealing gasket HLelaG series
The low-stress and high-efficiency sealing gasket HLelaG is a patented new product of Hengli Sealing. It has an innovative sealing body material and structure. The inner and outer sides of the sealing element are multi-turn special-shaped reinforced alloy belts. The special-shaped reinforced alloy belt plays a role in the sealing body. Protection and radial reinforcement. The main body of the seal is made of HLela high-elasticity, high-temperature and corrosion-resistant special flexible graphite tape wound and moulded.
Multi-layer toothed combined gasket (DCGG series)
Cixi Hengli Sealing Material Co., Ltd. patented new product (Patent No.: ZL201420339040.9) multi-layer tooth-shaped composite gasket (DCGG series), which uses two single-sided tooth-shaped composite gaskets and a high-elasticity non-metallic gasket. become. The tooth-shaped structure of the single-sided tooth-shaped composite gasket is different from the traditional tooth-shaped gasket, and it is also different from the wave-tooth composite gasket. This unique tooth-shaped structure makes the non-metal composite layer composite stronger, and the surface stress of the gasket is The distribution is more even. The combination of multi-layer metal framework and multi-layer non-metallic layer enables the gasket to obtain greater elastic deformation.
Radially reinforced prestressed gasket YYLG series
The radially reinforced pre-stressed gasket YYLG is a patented new product of Hengli Sealing. It has an innovative sealing body material and structure. The inner and outer sides of the sealing element are multi-turn special-shaped reinforced alloy belts. The special-shaped reinforced alloy belt plays a role in the sealing body. Protection and radial reinforcement. The main body of the seal is made of high-elasticity, high-temperature and corrosion-resistant special flexible graphite tape wound and molded.
HLG550 spring reinforced metal sealing ring
The spring-reinforced metal sealing ring is a spring-reinforced metal sealing ring, which has the advantages of good fit, outstanding sealing performance and low tightening force. It can be used in vacuum, extremely low temperature and high temperature environment, and it will not produce indentation on the flange after use. Its sealing leakage rate can reach 1×l0⁻⁹std.cc/sec, and it can be used in machinery, precision instruments, nuclear power, aviation, petrochemical and other fields with high sealing requirements.
Flexible graphite thread is made of flexible graphite and natural fiber, synthetic fiber, metal alloy wire and other reinforcing materials, adding a binder, and through a specific process to make various types of reinforced flexible graphite threads for weaving different flexible graphite packings. <br> The braided packing made of different fibers and reinforced metal wires, reinforced flexible graphite threads, can be used for sealing under different medium environments, different temperatures and different pressures. According to the harsh corrosive environment and user needs, corrosion inhibitor type sealing elements can be added to the graphite wire to prevent corrosion, and the performance will be more perfect.
