GRP Insulated Steel Pipe

GRP Insulated Steel Pipe

The steel-jacketed steam insulation pipe is composed of an outer protective steel pipe with anti-corrosion and insulation layers, and an inner working steel pipe. It is suitable for conveying steam or other mediums below 2.5MPa and 350 degrees Celsius. The outer protective layer is made of steel pipe, providing high strength, damage resistance, easy construction and maintenance, and a long service life.

Insulation Structure of Fiberglass Insulated Steel Pipe:

The insulation structure of the steel-jacketed insulation pipe is divided into internal sliding and external sliding based on the sliding method.

1. Internal Sliding:
   The insulation structure consists of a working steel pipe, alumina silicate, friction-reducing layer, microporous calcium silicate, heat-insulating layer, stainless steel fastening strap, aluminum foil reflector, polyurethane insulation layer, outer steel pipe, and external anti-corrosion layer (basic discontinued).
2. External Sliding:
   The insulation structure consists of a working steel pipe, glass wool insulation layer, aluminum foil reflector, stainless steel fastening strap, sliding guide bracket, air insulation layer, outer protective steel pipe, and external anti-corrosion layer.

Components:

1. Anti-corrosion Layer: Protects the outer steel pipe from corrosion, extending its lifespan.
2. Outer Protective Steel Pipe: Shields the insulation layer from groundwater erosion, supports the working pipe, and withstands external loads to ensure normal operation.
3. Glass Wool Insulation Layer, Air Insulation Layer: Maintains medium temperature and keeps the surface of the outer protective pipe at room temperature.
4. Aluminum Foil Reflector: Prevents organic foam materials from entering the inorganic hard, high-temperature-resistant layer; reflects part of the heat.
5. Inorganic Hard Insulation Layer: Resistant to high temperatures, ensures interface temperature with organic insulation layer, prevents foam from carbonization.
6. Stainless Steel Fastening Strap, Sliding Guide Bracket: Ensures free thermal expansion and contraction of the working steel pipe.
7. Working Steel Pipe: Ensures the normal flow of the conveyed medium.

Features of Fiberglass Insulated Steel Pipe:

1. Reduces project costs.
2. Low thermal loss, energy-saving.
3. Corrosion-resistant, excellent insulation performance, long service life.
4. Occupies less space, quick construction, environmentally friendly.
