Nuclear power plants

Gaskets

This expanded graphite tape filler spiral wound gasket is used for pressure vessels, heat exchangers and valves of nuclear power plants. It is designed to cope with the high temperatures and pressures in nuclear power plants, and we control soluble chlorine, fluorine and sulfur in the production process to make it suitable for such plants.

Packings

This packing is suitable for nuclear power plants. The amounts of soluble chlorine and fluorine are controlled in the production process.

Thermal insulation material

This metallic heat-insulating material is used for the reactor pressure vessel, recirculation equipment, and all apparatuses and pipes. It is made of thin stainless steel sheet to prevent corrosion, has high mechanical strength, and can be easily and quickly attached or detached, reducing exposure dose during working.

Thermal insulation material

This Thermal insulation material is used in nuclear power plants to control halogen components.

Building penetration part sealing material

This special rubber expansion joint is used to seal the gap between the through-hole and pipes that penetrate buildings, walls, and floors in nuclear power plants. It has good radiation resistance, heat resistance, and flexibility, and is therefore used as a seal to block air contaminated by radioactivity, steam generated during an accident, smoke, hot water, and water during a fire.
