The internal and external coatings of the pipe protect it from corrosion and prevent chemical and mechanical interactions with the pipeline walls. The effectiveness and quality of the coating determines the quality and reliability of the pipe over time. D'Amore & Lunardi S.p.A. supplies pipes for pipelines with the following protective coatings:
Coating layer that protects the external surface of the pipe from oxidation with a duration, outdoors, of six months. The coating is executed by:
Long life anti oxidation coating suitable for aboveground pipelines. The coating is executed by:
It’s the odest kind of coating but commonly used today for water pipelines, gas distribution on the rough ground and underground waterlogged, corrosive and saline ambient. The coating is carried out as follow:
Typical coating for small quantities having the technical characteristics of high dielectric strength, high chemical resistance to acids and high resistance to cathode disbanding. The joints are easy to restore and it is used for underground pipelines for water, gas, petrol. Executed in accordance with UNI 10190, ASTM D 1000 or any other customer requests. The coating is executed by:
Most popular coating with a high resistance to knocks and abrasion, to chemical and atmospheric agents with high dielectric strength. Executed in accordance with UNI 9099 and/or DIN 30670 or any other customer request. The coating is executed by:
- Epoxy resin primer.
- Polyethylene layer (extruded or sideband).
Part of a family of new generation two-component coatings (base+catalyst), with high resistance to impact, abrasion, chemical and atmospheric agents, high dielectric strength and high resistance to thermal excursion.
The coating is executed as follows:
Used for underwater pipelines, it is applied according to customer requirements.
Applied by concrete overweighting to 60 mm. thickness with interior steel wire reinforcement and anticorrosion protection.
All coating operations are monitored during the different stages of the production process as required by the reference standards and technical specifications of the products used. At the end of the production cycle and before shipment the certificates are issued bearing the result of the tests carried out and conformity of the coating/painting to the standards and/or customer requirements.
