Rock wool felt

  • Introduction
  • Parameters

Rock wool seam felt is a kind of soft and roll product made of rock wool felt wrapped by wire netting, stainless steel netting or glass wire, mainly used for heat preservation of large-caliber pipeline, storage tank, large-scale equipment, irregular thing, valve and pipe joint. Iron wire and stainless steel wire seam felt is especially applicable for heat insulation of high-temperature equipments.


Scope of application:
Rock wool light felt---It is used for heat insulation and sound absorption of large-caliber pipeline, construction wall and roofs.
Rock wool glass cloth felt----It is used in large-caliber industrial equipment and construction structure with the properties of anti-break and easy for construction. Furthermore, it has dust proof for construction wall.
Rock wool wire netting felt---It is used in strong-shake and high-temperature conditions. It is usually recommended to be used as insulated materials of boiler, shipping, valve and large-caliber and irregular pipelines.
