Why a formal cleanliness report is essential for turbine and high-pressure pipelines

Passing a hydrotest confirms that a high-pressure pipeline can withstand pressure. The real challenge is internal cleanliness: even the smallest particle can cause erosion, valve blockage and costly downtime, putting the reliability of a turbine system at risk.

For us, pipeline cleanliness is as critical as welding quality, prefabrication, installation and a successful hydrotest. A clean pipeline reduces the risk of failure, gives a reliable start-up and extends the life of turbine and high-pressure systems.

Our approach: a formal cleanliness report

Every pipeline we fabricate for a high-pressure system concludes with a formal Cleanliness Report:

• Scope: which sections of the turbine pipeline and which line packages are included in the verification.
• Cleaning procedure: internal cleaning with compressed air at 9 bar, removing dust, particles, scale and foreign material from the pipe walls.
• Inspection and acceptance criteria: visual and functional checks to the cleanliness specification (customer or OEM), with NDT where necessary.
• Results: every inspected pipe must pass with no visible residue or contaminants above the allowed limits.
• Conclusion: the pipeline meets the quality requirements and is ready for safe commissioning.

Why this matters

Holding pressure alone does not guarantee operational readiness. Cleanliness reports together with hydrotests, NDT and certified welding reduce downtime, make commissioning smooth and extend the life of the equipment.

Each report is signed and stamped — reliable quality documentation for the project handover.
