Multi-component liquid MCLMulti-Component Liquid (MCL) coating systems are widely used for the protection of the welded joint area. CRC-Evans specializes in the installation of MCL systems, by the use of automated, on-pipe, spray equipment, offering repeatability, and continuity in quality. The multi-component liquid (MCL) systems offer:

  • Compatibility with factory-applied line pipe coating
  • Excellent corrosion protection and mechanical properties
  • Short application cycle times
  • Rapid curing characteristics (following induction pre-heat), allowing for faster lowering in and back fill
  • Repeatable quality, verified by simple onsite inspection, and testing procedures

Automated Application System
In order to meet industry needs, field joint services developed a fully automated machine to apply MCL coatings to the weld joint area. This pre-programmable automated spray equipment allows for a fast, consistent, high-quality application of the field joint system, to each and every weld area.

CRC-Evans' automated, on-pipe coating machine applies material by rotating around the pipe a predetermined number of times, evenly building up the required thickness of material over the weld area. Application time is often 1 minute or less, allowing for very high production rates.

Fully Automated Spray Technology
The Fully Automated Spray Technology (F.A.S.T.) system has improved features for the monitoring of material parameters, along with automatic (real-time) checking of the pumping equipment to ensure that the material is being applied at the correct conditions and in the correct mix-ratio, at all times.

F.A.S.T. is a fully automated, pre-programmable spray system that significantly reduces the risk of human error, ensuring repeatable quality and the long-term integrity of the coated field joint area.
