SPECIAL COATING STATION

A customer approached us with a Technical Assignment to design and build a station for the application of the multicomponent coating Green Well to the pin and box threaded parts.

The challenge of the project was to isolate the coating application zone from the environment and to fit it with a high-performance exhaust ventilation system to remove the harmful vapors and particles of compound from the working area.

The station is to be compact and effective for a wide range of pipes and be sufficiently mechanized to facilitate manual labor.

PURPOSE

Application of GREENWELL coating to the surface of threaded connection to eliminate the use of sealing grease when making threaded pipe and collar connections.

  1. GREENWELL coating application chamber is an enclosed steel compartment with a door and feed system, lighting and exhaust ventilation systems.
  2. The pipe rotation drive ensures rotation of the pipe at 35-45 rpm. All rollers have polyurethane coating.
  3. The collar rotation system is a retractable table with a drive and polyurethane rollers ensuring collar rotation at 35-45 rpm.
  4. The roller conveyor feeding the pipe end to the chamber (bogey) is a mobile device with two stands fitted with rollers. All rollers have polyurethane coating.
  5. Control panel allows switching between modes of operation: pipe and collar rotation speeds, control of treatment time on phases of technological process, and has an emergency shutdown function.
  6. The control cabinet ensures connection of cables and wires.
  7. The cable management system (ducts, lids, cables) ensures power supply to the components of the station.

The transport system is the roller conveyor feeding the end of the pipe to the chamber for the application of coating. The conveyor moves the pipe to the chamber. Wheels are locked when the coating application is in progress. Depending on the pipe diameter, the conveyor stands may be adjusted by height.

02

The collar rotation system is a retractable table with a drive for the rotation of rollers.

01
