China Tubular Airless Painting (Spraying) Production Line - Suppliers & Factory for Oilfield Industry
Product Features
Intelligent Spray Technology
Auto-calibrating spray guns with diameter-adaptive extensions to accommodate different pipe diameters. The spray guns we adopted is Chinese and world famous brand.
Coating Efficiency System
The System is designed for overspray recovery rate reach to 98% and closed-loop recycling with automatic viscosity compensation.
Production Optimization
The innovative design enables faster production line speeds for increased productivity.
Auto Cleaning Systems
Auto cleaning starts if the machine stops working for 4 hours, save time for production.
Curing Systems
There is Intermediate frequency furnace and inductive coil if necessary to speed up the coating drying time.
Automatic Handling Equipment
Automatic systems often include conveyors and other handling equipments to move steel pipe through the various stages of the painting process.

Frequently Asked Questions (FAQ)
What kind of paint is compatible with this spraying system?
The system is designed to use water-based or oil-based hard film anti-rust coatings.
What is the overspray recovery rate?
Our coating efficiency system is engineered to achieve an overspray recovery rate of up to 98%, featuring closed-loop recycling with automatic viscosity compensation.
How does the auto cleaning system work?
To save production time, the auto cleaning system automatically activates if the machine stops working for 4 consecutive hours.
What is the standard spraying speed and coating thickness?
The spray speed operates between 0.8 to 1.0 m/s, providing a uniform coating thickness ranging from 10 to 35 μm (dry film).
Can the system speed up the drying process?
Yes, curing systems such as an intermediate frequency furnace and inductive coil can be integrated if necessary to significantly speed up the coating drying time.
Which industries typically use this equipment?
It is widely used for casing & tubing (API 5CT), drill pipes & collars (API 7-1), seamless pipes for offshore platforms, and high-strength steel components (X80+ grades).
