The insulation structure of the stainless steel seamless elbow is divided into jacket elbow, jacket elbow layer, working elbow, working pipe layer, aluminum foil reflective layer, glass wool layer, stainless steel fastening steel strip, sliding guide bracket, and air insulation layer.
The following analyzes the role:
1. Polyurethane foam layer: medium problem, the surface of the jacket elbow should be kept at normal temperature.
2. Jacket elbow: protects the insulation layer from underground water corrosion, supports the work pipe and withstands corresponding external loads, so that the work pipe can operate normally.
3. Jacket elbow layer: protects the jacket elbow from corrosion and extends the service life of the elbow.
4. Working elbow: the transport medium flows normally.
5. Working pipe layer: Prevent the working elbow from being corroded by corrosives and extend the service life of the working elbow.
6. Drag reduction layer: The working elbow can move freely with thermal expansion and contraction.
7. Inorganic hard insulation layer: The interface temperature between the inorganic hard insulation layer and the insulation layer prevents the polyurethane foam from being carbonized.
8. Reflective layer: The foam material will not enter the inorganic hard insulation layer and reflect part of the heat of the insulation layer.
