3PE Anti-Corrosive Blasting Coating Steel Pipe 3-Layer PE Pipe Machine

3PE Anti-Corrosive Blasting Coating Steel Pipe 3-Layer PE Pipe Machine

Description

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.

The epoxy powder is a kind of thermosetting nontoxic coating, forming the high molecular weight cross-linking structure coating after solidifying, featuring good chemical anticorrosion and higher mechanical properties.The function of epoxy-powder bottom layer is to form continuous coating, providing excellent adhesion by agglutinating and solidifying the steel tube surface with good chemical resistance and cathodic disbanding resistance.The function of polymer adhesive is to agglutinate the epoxy powder before gelation, and to agglutinate the polyethylene top layer, which unites all three layers together.The three-layer PE process, with the epoxy powder coating as bottom layer, binding and bundling through polyethylene PE and adhesive, is widely used in anticorrosion of steel pipes at home and abroad, and applied to the oil pipeline and gas pipeline, as well as to the gas supply and water supply for civil use.

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 μM,
Copolymer layer of minimum thickness of 250 μM,
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.
