Understand the galvanized wire equipment, insulation layer, maintenance layer of the specific design requirements, and now we look at galvanized iron wire equipment at other levels of specific design requirements:
Galvanized iron wire equipment - moistureproof layer design request
1, equipment and piping cold preservation layer surface, buried or trench laying pipeline insulation layer surface, should be provided with moisture-proof layer.
2, in the environment changes and vibration conditions, moisture-proof layer should be able to adhere to its structure of integrity and tightness.
3, asphalt, rubber waterproof cold glue glass protection layer composed of tidal, should be consistent with existing national standards "of industrial equipment and pipeline insulation engineering construction and acceptance standard" (GBJ126-89) rules.

The hook and pin used for the insulation layer should be made of low carbon round steel of phi 3 to 6mm, and lower limit should be adopted for soft insulation material.
1, rigid material insulation nails between 300 ~ 600mm, and nails should be based on the geometric size of the products in the joints for climbing insulation column column.
2, flexible data insulation nails between the distance should not be greater than 350mm. The number of nails per square meter area is: the side should be less than 6, and the bottom should be less than 8.
3 it is not suitable to use the nail nail structure in the cold preservation layer.
4, the vibration of the hook should be properly encrypted.
We hope that through our introduction to galvanized iron wire equipment, you can buy and use galvanized wire equipment.
