    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.
