One step equipment:

The new "one-step" process features:

1. Widely used materials, can be made of epoxy powder and a variety of coatings on steel pipe corrosion.

2. Foam can be made of polyester high temperature foam and pitch black foam.

3. The jacket layer is bonded to the foam layer, the foam layer is bonded to the anti-corrosion layer, and the anti-corrosion layer is bonded to the steel pipe firmly.

The steel pipe insulation and anticorrosion production line built by one-step forming method has high degree of automation, and the quality of insulation and anticorrosion coating fully meets the national standard.

The advantages of one-step polyurethane insulation pipe production line are as follows:

1、 The utility model has the advantages of long service time, cost saving, high efficiency and environmental protection.

2、 The operation line adopts automatic rectifying machine with high precision, stable operation and good rectifying effect.

3、 The operation line adopts rubber wheel transmission to effectively prevent the external environment from damaging the anticorrosive coating of steel pipe.

Four. The jacket layer of the operation line is tightly bonded with the foam layer, and the foam layer is also tightly bonded with the anticorrosive coating. The anticorrosive layer and the steel pipe are firmly bonded to ensure the sealing and durability, and the damage phenomenon is not easy to occur.
