Asphalt paint coating

The asphalt paint coating is used on gas transmission pipelines. Preheating the pipes before painting enhances the adhesion of the asphalt paint and accelerates drying.

2. Cement mortar lining + special coating

This internal corrosion prevention measure is suitable for pipelines transporting wastewater, enhancing the anti-corrosion capability of the lining.

Epoxy coal tar coating

Epoxy coal tar coatings are suitable for both gas pipelines and sewage pipelines. It is a two-component coating with high adhesion and an extremely smooth surface.

4. Epoxy ceramic lining

Epoxy ceramic lining is suitable for sewage and gas pipelines, but due to the high manufacturing difficulty and cost, it has certain limitations in application. The epoxy ceramic lining boasts high adhesion and smoothness, making it an excellent anti-corrosion coating.

Aluminate cement coating or sulfate cement coating

These specialized cement coatings are both suitable for the internal corrosion protection of Ductile Iron Pipes (DIP) used in sewage pipelines, enhancing their resistance to erosion caused by acidic and alkaline components in wastewater.

6. Polyurethane Coating

A new type of green special coating developed to meet environmental protection needs, featuring excellent wear and corrosion resistance.
