China Tubular Airless Painting Production Line Supplier - High-Speed Factory Solution for Optimal Corrosion Protection
Product Features
Auto-calibrating spray guns with diameter-adaptive extensions to accommodate different pipe diameters. The spray guns we adopted is Chinese and world famous brand.
The System is designed for overspray recovery rate reach to 98% and closed-loop recycling with automatic viscosity compensation.
The innovative design enables faster production line speeds for increased productivity.
Auto cleaning starts if the machine stops working for 4 hours, save time for production.
There is Intermediate frequency furnace and inductive coil if necessary to speed up the the coating drying time.
Automatic systems often include conveyors and other handling equipments to move steel pipe through the various stages of the painting process.
