Three-Layer Polyethylene Steel Pipe Liquid Coating Blasting anti-corrosion pipe

Product Specification

Three-Layer Polyethylene Steel Pipe Liquid Coating Blasting anti-corrosion pipe Line Machinery
 
Description

3LPE coating processing line is to make anti-corrosion of kinds of steel pipes, such as single layer FBE, double layer FBE, double layer PE, double layer PP and 3PE.

Application
The coating technology allows to obtain the anticorrosive three-layer polyethylene/polyetylene coating, which consist of:
Epoxy layer,
Copolymer layer (bonding agent),
Polyethylene/polypropylene layer.

Main Equipment List

The coating is applied on steel pipes of diameters from 159 mm to 1420 mm and length from 6 m to 18 m. Properties of applied coatings comply with the following stan- dards:
EN-PN ISO 21809,
DIN 30670,
DIN 30678,
NFA 49-710,
EN-PN 10285.
The anticorrosive coating consists of the following layers:
Epoxy layer of minimum thickness of 80 μ M,
Copolymer layer of minimum thickness of 250 μ M,
Polyethylene layer of minimum thickness between 1, 8 mm and 3, 7 mm or polypropylene layer of minimal thickness between 1, 8 mm and 2, 5 mm.
"FERRUM" S. A. Manufactures coated steel pipes in diameter from 159 mm to 1420 mm and length from 6 m to 18 m. We provide coating services with reference to pipes delivered by our custo- mers.

The coating manufacturing process consists of the following operations:
The surface blast cleaning to Sa 2 1/2 acc. To ISO 8501-1,
The electrostatic spraying of epoxy powder onto a heated pipe,
Wrapping a pipe with extruded copolymer,
Wrapping a pipe with polyethylene/polyetylene in continuous way,
Cooling the coating and dressing the pipe ends.
