Product Name : EN-PN ISO 21809 3pe coating steel pipes ?the definition of anticorrosive steel pipes

 

 

Best Pipeline is the main manufacturer of the anticorrosive, extruded, three-layer, polyethylene/polyethylene co- ating on steel pipes. 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 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.

 

 

An extruded polyethylene coating has higher mechanical properties in comparison with cold applied polyethylene tape coating. Anticor- rosive coatings made of three-layer PE/PP are characterized by:

· high mechanical strength,

· high adherence of the coating to the pipe,

· guaranteedlong-lastinganticorrosiveprotectionofundergroundpipelines for minimum 50 years,

· 100% protection of weld zone of coated longitudinally and spirally welded pipes,

· suitability for bending of coated steel without damaging the insulation layer.

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.
