Riveco GeneralSider Tubi in acciaio e rivestimenti anticorrosivi

The 3LPP coating is a passive protection technique used when service temperature are high up to 110° C, in presence of mechanical and corrosion risks, in order to enhance the scratch, penetration, peeling resistance, with long lasting performances.

It can be used for water, oil and gas, submarine linepipes and special services, for onshore and offshore applications, according to the international standards DIN 30678, NFA 49711, ISO 21809-1 and to Customer’s requirements.

Size Range

3LPP coating from dia ¾” (26.7 mm) to dia. 70” (1778.0 mm), lengths from 6.0 m to 16.0 m. It’s applied with both side-banded and sleeve extrusion methods, with traditional liquid or FBE primers with grafted adhesive for applications where maximum adhesion, penetration resistance and high durability are required. Tailor made application according to Customer’s specification and requirements. We have our own test and research laboratories.

IN-DEPTHS

The advantages of Polypropylene are:

Higher resistance to corrosion also at higher temperatures
Higher dielectric properties
Higher resistance to penetration, impact, abrasion
Higher adhesion values to steel through a large temperature range (excellent test results at cold and hot temperatures)
Lower water absorption, lower permeability to steam and oxygen
Excellent results to cathodic disbonding
Good flexibility, resistance to deformation and elongation (close to PE results)

Note: Polypropylene has lower resistance than Polyethylene at very low temperatures.
