PREZIOSO Linjebygg has developed a Piping Integrity Programme (PIP) to perform maintenance on critical process piping systems during operation. Corrosion under pipes at pipe-support locations are solved by lifting the pipes under controlled conditions with consequent surface inspection and repair.
Our teams provide engineering and execution services to inspect and maintain pipes during operation, comprising:
- The design of a purpose-made pipe lift program, including lifting tables to secure material stress levels within design codes
- Separate stress calculations are performed for cases outside existing lifting tables
- Inspection (visual/NDE)
- Pipe repair and surface treatment
- Wrapping solutions (to prevent corrosion and strengthen walls).
