Project Description

LF epoxy – Antifriction epoxy

INTERNAL LINING

LF epoxy – Antifriction epoxy

LF Epoxy lining combines outstanding application characteristics with good corrosion protection, anti-friction property and chemical resistance. The film helps pigging and hydrostatic tests on the pipe, it provides a considerable improvement of the gas flow in service, avoiding the carried product to be contaminated by mill scales or scales deriving from chemical and physical degradation of the steel substrate. The considerable long term advantages are referred to pumping costs of the product, and to a long term protection against corrosion. This coating is recommended thanks to its relatively low thickness and to the high performances offered.

Long-term anticorrosive protection
Offers significant long- term advantages in relation to the product’s pumping costs, together with long-term protection from corrosion.

Very good mechanical protection

  • Facilitates pigging operations,
  • Facilitates tests on piping,
  • Significant increment in the service gas flow.

Other advantages of LF epoxy coating
Avoids contamination of the transported product caused by lamination slag or compounds deriving from the chemical/physical deterioration of the piping’s steel surface.

  • Small and large pipes
  • Standard and special fittings
  • Wide radius bends
  • Flanges
  • Valves
  • Field joints
  • Custom pieces
  • SURFACE PREPARATION : The steel surface is thoroughly cleaned and blasted.
  • ANTIFRICTION EPOXY : Application of bi-component low friction epoxy by spray or using a turbine.
  • SHIPMENT PREPARATION : Final inspection is carried out in our internal laboratory when the goods are fully produced, packed and in all respects ready for shipment.
