Electric, Power & Gas

The demanding process conditions in Power Plants (including high temperatures and pressures) is an ideal environment for NICHIAS product technologies to be deployed.

Various NICHIAS thermal insulation and protection technologies are deployed from metallic heat insulation with Lead, to Wall penetration part sealing materials, to specialist gaskets proven in use in the NUCLEAR Industry, to re-usable flexible heat insulation materials, calcium silicate thermal insulation materials and high damping rubber/metal composite sheets used in THERMAL POWER Plants.
 

Nuclear Power Plants

The extreme process conditions in Nuclear Power Plants has demanded the use of NICHIAS product technologies.
 
NICHIAS supplies Wall penetration part sealing materials which are used on walls and floors through which piping and cabling pass - as it has excellent air tightness, water tightnesss and radiation resistance, to  metallic heat insulation with lead which is used as a heat insulation material for applications requiring radiation shielding performance as in equipment and piping inside the reactor containment vessel (lead sheets are combined with the metal heat insulation materials),  to metallic heat insulation materials used for the pressure container of nuclear reactors in re-circulation equipment, to specialist bellows (flexible expansion joints made of special rubber materials) which are used to seal the clearance between the pipes penetrating buildings, walls and floors and the pipe holes in a nuclear power plant, to specialist gaskets proven in use in the nuclear industry, to re-usable flexible heat insulation materials for the insulation of piping, valves, flanges, etc where the insulation material needs to be able to be removed during plant inspection and maintenance.
 

Thermal Power Plants

A variety of NICHIAS product solutions are deployed in a Thermal Power Plant.
 
NICHIAS supplies multiple thermal insulation materials ranging from rock wool used as thermal and acoustic insulation in ducts boilers and dust collectors, to calcium silicate thermal insulation materials used for various piping and ducts since it is easy to install and has high mechanical strength and water resistance to castable refractories used for protecting iron plates and refractory bricks in boilers from acidic gases and heat, to re-usable flexible heat insulation materials for the insulation of piping, valves, flanges, etc where the insulation material needs to be able to be removed during plant inspection and maintenance, to specialist gaskets used as sealing materials for piping flanges, valves and equipment both of high temperature and pressure duty but also low temperature and pressure duty, to high damping sheets (Metalamine™) which is an exterior pipe acoustic insulation sheet used on the smoke paths, airways, electric dust collectors, etc of a thermal power plant to reduce noise and vibration generated.
