Piping
Piping Work Process
Piping installation
- Checks the code for the materials of pipes and valves (approved P & ID).
- Checks the ISO drawings.
- Checks the hook-ups and insulation kits on the drawing.
- Checks the quality of welding (piping and wall penetrations).
- Checks the valve tag plates.
- Checks for the existence and degree of deformation after the Installation of pipes.
- Checks the soundness of installations before a pressure test of pipelines (including supports).
Applications
- New shipbuilding projects, offshore plants, land plants.
- Petrochemical plants, power plants, semiconductor plants
- Nuclear power plants

Installation
Valve installation
Valve installation and nitrogen gas leakage tests
- Before installing the valve on a testbed, the valve is closed, and a leak test is performed using N₂ gas of 5 bar to measure the leak rate (Bubbles/min.) at the outlet of the valve.
- International standards and codes for valve testing (ASTM, ASME B16.5, B16.9, B31.3, API 598 etc.)
- If the volume of leakage is beyond the acceptance criteria, a repair job is performed after negotiating with the valve vendor.
Applications
- New shipbuilding projects, offshore plants, land plants.
- Petrochemical plants, power plants, semiconductor plants
- Nuclear power plants
