China Suppliers Factory for Tubular Airless Painting (Spraying) Production Line for Oil Tubulars and Steel Pipes
Product Features
Auto-calibrating spray guns with diameter-adaptive extensions to accommodate different pipe diameters. The spray guns adopted are from world-famous Chinese and international brands.
Designed for an overspray recovery rate of up to 98%, featuring closed-loop recycling with automatic viscosity compensation.
Innovative system architecture enables faster production line speeds for substantially increased throughput.
Automatic purge and cleaning cycles initiate if the machine remains idle for 4 hours, preventing downtime and maintaining quality.
Configured with intermediate frequency furnaces and inductive heating coils where required to accelerate paint curing and drying.
Integrated automated conveyance and mechanical handling components transition steel pipes smoothly across every coating phase.
Industry Applications
- Casing & tubing (API 5CT)
- Drill pipe & collars (API 7-1)
