Archco-Rigidon protects injector spools

44B_0514

Injector spools for Cristal Pigments coated internally with Archco Rigidon 503D & 403D and completed with a wax top coat.

IMMINGHAM-based Painting and Labour Ltd is a long-term user of Winn & Coales (Denso) Ltd’s Archco-Rigidon 403D and 503D glass flake vinyl ester coatings.

The company has been regularly contracted to line internal surfaces of pipework, tanks and vessels and also injector spools with these specialist interior protective coatings, following shot blasting to the Swedish Sa 2½ standard near white metal.
Cristal Pigments, also of Immingham, is a leading customer for Painting and Labour’s services for protection of injector spools, pipework and process tanks. Pretreatment and Archco-Rigidon application of injector spools and pipework was carried out at Painting and Labour’s workshop. The specification was as follows:
Following blast cleaning of internal surfaces to Sa 2½, the first coat of Archco- Rigidon 503D was applied to approximately 1000 microns. A second coat consisting of Archco-Rigidon 403D was applied to 1000 microns thickness to achieve an overall thickness of 2000 microns. A final 250 microns coat of Archco-Rigidon Blue Wax Topcoat was then applied. Final thickness readings were taken and full Holiday detection was carried out to ensure the work was in line with the specification requirements. Whilst carrying out the lining work Cristal Pigments representatives carried out inspections of the processes and reported their full satisfaction with the work meeting the specification requirements.
Painting and Labour also lined two small receiver vessels onsite at Cristal Pigments – one of them only required coating with Archco-Rigidon 403D on the bottom dish end after blast cleaning. The full vessel specification was: blast cleaning to Sa 2½ followed by multiple brush applied coats of Archco-Rigidon 403D to achieve l000 microns overall thickness. On completion of lining both vessels were checked for film thickness and Holiday detection readings.
