Spiral Submerged Arc Welding Of Polyethylene Lined Pipes
Epoxy Resin Primer
The epoxy resin primer is to be applied in powder form. The minimum layer thickness is 60μm.
PE Adhesive
The PE adhesive can be applied in powder form or extruded. The minimum layer thickness is 140μm. the peel strength requirements vary depending on whether the adhesive was applied as a powder or was extruded.
Polyethylene Coating
The polyethylene coating is applied either by sintering or by sleeve or sheet extrusion. The coating is to be cooled after application to avoid unwanted deformation during transport. Depending on the nominal size, there are different minimum values for the normal total coating thickness. In the case of increased mechanical loads the minimu layer thickess shall be increased by 0.7mm. minimum layer thickness are given in table 3 below.
