There are two anticorrosion pipes producing techniques to choose from: the coating type and the enwrapping type. The coating type is more suitable with smaller sizes steel tubes (i.e. steel tubes size below Φ600mm), steel tubes would be located in the central of the pipe die and be coated from there.

The enwrapping type is suitable for larger sizes; currently it is capable to achieve enwrapping steel tube size from Φ79mm up to 2540mm. The extrusion line consists of the following machineries components: steel tube convey system, surface pre-heating system, steel tube dust removal system, electrostatic spraying and cleaning system, tube heating system, spraying system, coating and enwrapping system, water-cooling system, end-grinding system, coating inspection system cutting system and electronic control system.
