3 -laags PE Coating Steel Pipe Technische instructies
Structuur van de stalen buis van 3PE -coating
Drie lagen PE-coating anti-corrosieve stalen buis voert de standaard van GB/T23257-2009 en DIN30670 uit.
Structuur: binnenstalen buis, epoxypoedercoating, middelste kleeflaag, buitenste laag van polyethyleen met hoge dichtheid
De voordelen van antiseptische pijp
1. Perfecte impactweerstand, wrijvingsweerstand, schokweerstand
2. Zoutweerstand met hoge zuur alkali
3. Hoge weerstand van elektrische schok
4. Laag sijpelende watersnelheid
5. Lange gebruikstijd
