Our pipe type BK is produced based on DIN 16965 Part 2 and has a thermoplastic inliner that varies depending on the application. This can consist of PE, PP, PVC-U red, PVC-U Dekadur Plus, PVDF, PP, E-CTFE, PFA, MFA and FEP. Depending on the type, in addition to an adhesive layer of 1mm as an adhesion promoter on the sanded liner, a glass lamination (depending on the material) as adhesion for the load-bearing laminate structure is required.
The layer structure corresponds to our pipe type K and also includes a C glass fleece as the outer layer, as well as a weather-resistant finish over 0.2mm. The type of glass varies depending on the application (E or E-CR glass), as does the resin. The load-bearing layer has a glass content of 45% (+/- 5%).
Our pipe type BK (and also type K as a basis) each have an individual material report according to the Pressure Equipment Directive:
