Glasswool pipe
　Dongying huadeli glasswool pipe sections are suitable for any hot pipe;cold pipe;hinded or exposed thermal insulation.The higest using temperature is 400°C.Usually they are used for the thermal insulation and sound -absorbing in shop building;industry facility;civil construction and power plant. The products are anti-corrosion nosmell un-humidity-absorbing ,no mildew anti-bacterium.they are suitable for each kind of conditioner system and each kind of light industry pipe system.there is a layer of enforcement aluminum foil (FSR)on the outside surface of the pipe section,that could affectly prevent condensation and prevent freeze.when we want to control condensation we use unti-humidity facing material to seal around the outside surface of the pipe .the glasswool pipe section could reduce the noise made by the pipe system. The pipe with 100 mm thickness could reduce 31 db noise and pipe with 50 mm thickness could reduce 28 db noise.
