DIN 30670 Polyethylene Coatings on Steel Pipes and Fittings - Requirements and Tests

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DIN 30670 testing. This standard specifies requirements for factory-applied three-layer extruded polyethylene-based coatings and one- or multi-layer sintered polyethylene-based coatings for corrosion protection of steel pipes and fittings.

The coatings are suitable for protecting buried or immersed steel pipes at design temperatures of -40°C to +80°C.

This standard specifies requirements for coatings applied to longitudinal or spirally welded or seamless steel pipes and fittings used in the construction of pipelines to transport liquids or gases.

The application of this standard ensures that the PE coating provides adequate protection against mechanical, thermal and chemical loads during operation, transportation, storage and installation.

DIN EN ISO 21809-1 specifies international requirements for three-layer extruded polyethylene and polypropylene-based coatings for steel pipes for oil and gas pipeline transport systems.

The following application areas are not covered by DIN EN ISO 21809-1:

• All polyethylene based coatings for steel pipes and fittings used for the transport and distribution of water and wastewater;
• All polyethylene-based coatings for steel pipes and fittings in distribution pipelines for gaseous and liquid media;
• Single and multi-layer sintered polyethylene-based coatings for steel pipes and fittings used for shipping pipelines and distribution pipelines.
