Frequently Asked Questions

Q: What is the difference between 3LPE and 3LPP coatings?

3LPE (Polyethylene) is ideal for standard temperatures and excellent corrosion protection, while 3LPP (Polypropylene) is designed for higher temperature environments and offers superior mechanical strength.

Q: When should I choose a 'Strengthened' type coating over a 'Normal' type?

Strengthened coatings (e.g., 2.5mm PE/PP) are recommended for pipelines in rocky terrain or areas where heavy mechanical stress is expected during burial and transport.

Q: How does the internal coating improve pipeline efficiency?

Our internal drag-reducing coatings create a smoother surface, which lowers turbulence and friction, thereby reducing the energy required for pumping liquids.

Q: What is FBE coating and what are its primary benefits?

FBE stands for Fusion Bonded Epoxy. It is one of the most advanced anticorrosive coatings, providing excellent adhesion and high resistance to cathodic disbondment.

Q: Can you provide internal coating for pipes larger than 700mm?

Our standard centrifugal internal coating process covers DN100 to 700mm. For larger diameters, please contact our engineering team for custom solutions.

Q: Are these coatings suitable for all types of liquid pipes?

Yes, these systems are designed for a wide range of liquid transport applications, including oil, water, and chemical pipelines, depending on the specific material chosen.
