Starting condition

Weather exposure, wet-dry cycling and mechanical damage had created a need for a continuous barrier across straight pipe runs and complex transitions.

Site constraints

Curved surfaces, supports, welds and restricted backsides make uniform preparation and thickness more difficult than on flat steel.

Engineering decision

Spray application was used for broad pipe surfaces, with controlled detail work around transitions and areas where spray angle or access could reduce coverage.

Execution process

  1. 01

    Identify corrosion, contamination, existing coating and repair areas.

  2. 02

    Prepare the steel and confirm cleanliness and profile before primer.

  3. 03

    Apply compatible primer within the approved environmental window.

  4. 04

    Spray the main pipe surface and detail elbows, welds and transitions.

  5. 05

    Inspect continuity and thickness; repair incomplete or damaged areas.

Inspection and commissioning

  • Surface-preparation and environmental-condition checks
  • Primer and recoat-window confirmation
  • Visual continuity and thickness review
  • Detail inspection at welds, supports and transitions

Documented outcome

The field image records a continuous protective coating applied over prepared outdoor pipe surfaces and transition geometry.

Project record and engineering details

Field photographs, application records and system drawings show the work from installed condition to technical detail.
