How our tube surface coating line is put together: the units, the specification and what we need from you to configure it.
In This Line
An in-line spray paint line for square tube 25 × 25 to 125 × 125 mm, supplied as an accessory to our tube mills and other lines.
Technical Specification Table

| Working process | Feeding device – cleaning device – heating device – painting device – transportation device – unloading device – stacking device – removal rack |
Line Configuration and Scope of Supply
The line is built from eight units in sequence: feeding device, cleaning device, heating device, painting device, transportation device, unloading device, stacking device and removal rack. Bundles of 300 × 300 to 600 × 600 mm are fed at the entry, and the coated tube is stacked and moved off on the removal rack. Integrators planning a complete coating plant can see our pipe coating line for integrators.
Standard lines ship within 90 working days of the deposit, with plant-level customisation scheduled from our own manufacturing base.
The line is dismantled into units and shipped in containers: heavy frames are braced and secured, while precision parts and wear items travel in wooden cases together with a spare-parts pack.
Our engineers travel to site to guide installation, commissioning and operator training; the buyer provides the installation crew and covers the engineers’ travel, lodging and daily allowance, and support continues online after handover. Our after-sales team handles enquiries.
Payment is 30% by T/T on signing, 65% by T/T before shipment and 5% after installation and commissioning, or by L/C at sight; prices are quoted ex-works (EXW).
Our quality management system is certified to ISO 9001:2015.
Size Change and Running Cost
Between jobs, what changes is the tube size and length, within square tube 25 × 25 to 125 × 125 mm and 6 to 12 m. The main running costs are paint, the cleaning medium and the energy used for heating.
When you enquire, send us the tube sizes and wall thicknesses you run, the lengths, the output you need coated and the coating specification your finished tube has to meet; the coating specification is the item most likely to change the configuration. Where coated tube is used is covered under pipe production applications.
