Product Description

DIN30678 3LPP/2LPP Coating Pipe

DIN 30678, 2013 Edition, September 2013 - Polypropylene coatings on steel pipes and fittings - Requirements and testing

This standard specifies requirements for factory-applied three-layer extruded polypropylene-based coatings, and one- or multi-layered sintered polypropylene-based coatings for the corrosion protection of steel pipes and fittings.

The present standard specifies requirements for coatings that are applied to longitudinally or spirally welded or seamless steel pipes and fittings used for the construction of pipelines for conveying liquids or gases.

Applying this standard ensures that the PP coating provides sufficient protection against the mechanical, thermal and chemical loads occurring during operation, transport, storage and installation.

3LPP/2LPP/polypropylene anti-corrosion coating is very important in coating industry.Three layer polypropylene coating operating temperature is -20C~110C, it is widely used in severe and complex conditions because of its excellent UV resistance and a wide range of operating temperature.We provide coating design service and have many coating machines.
