The company’s chemical tower and internals installation services combine technical expertise with safety-first execution. Installation projects follow a structured approach:
1. Site preparation:
- Foundation inspection (flatness within ±3 mm/m, anchor bolt alignment), installation of tower supports (skirt supports, saddles).
- Safety setup: Confined space entry protocols, fall protection systems, hazardous area classification (ATEX/IECEx).
2. Tower erection:
- Sectional assembly (for large towers), using hydraulic jacks for vertical lifting (tower plumbness control, < 1 mm/m).
- Welding of tower sections (qualified weld procedures, NDT per ASME Section IX).
3. Internals installation:
- Sequential installation: support grids, packing (if used), liquid distributors, gas distributors, mist eliminators.
- Precision alignment: tray levels (spirit level, laser), distributor height (measured from tower datum, ±2 mm).
4. Mechanical completion:
- Nozzle installation (blind flanges for testing), manway closure (gasket type: spiral wound, ring joint), insulation application.
5. Testing and commissioning:
- Hydrostatic test (1.5 x design pressure, held for 30 minutes), pneumatic test for low-pressure towers.
- Functional testing of internals (as above), final inspection before process connection.
Installation teams are certified in confined space operations, rigging, and welding, with project management software (Primavera) used to track progress and ensure on-time completion.
