Leak rectification of Pipelines in Offsite area and NP Plant, FACT-CD.

Leak rectification of Pipelines in Offsite area and NP Plant, FACT-CD.

Replacement / Erection of Rubber lined pipes and fittings. Work involves: Collection / transportation of rubber lined pipes and fittings from store / rubber lining area / plant area to the site. Damaged rubber lined pipes and fittings used for acids, ASL, Slurry etc. shall be dismantled from the site at various position / elevation / pipe bridges, after getting the process clearance. Suitable rubber lined pipes and fittings shall be erected with proper gaskets and tight the flange joint to avoid any leakage. The contractor shall ensure that the line remains leak-free.The contractor is responsible for ensuring proper pipe support on both sides of the pipelines schedule for replacement, to prevent any strain. If any shortages or excesses in pipe length are noticed during replacement, the contractor shall correct them and ensure that the pipes are installed without any strain or leaks in the pipelines. After the replacement, the damaged pipe shall be transported to the rubber lining area /plant area/scrap yard according to the shift engineer's instructions. The pipe sizes varies from 80NB to 200NB.

Fabricating and installing leak repair clamps for pipelines carrying various types of fluids. Work involves: Collection / transportation of required materials from stores / plant area. Fabricate leak repair clamps for pipelines carrying various fluids such as acids, fire water, cooling water, raw water, compressed air, etc., in different sizes, and keep them in stock for immediate replacement during pipeline leaks. Take neccessary permission/ clearance from respective dept. before providing/fixing the clamps at varied height. The pipe sizes for providing clamps varies from 25NB to 300NB.

Repair Of Pipeline Flanges for Leake Rectification : Work involves: Arrange the necessary tools and consumable required for the work. Dismanling the mating flange/pipeline for repairing the damaged flange after taking the neccessary clearance from respective depts. Repair the flange face at site by cutting, welding and grinding as instructed by Engineer-in-Charge. Fix back the mating flange/pipieline with new gasket and servicing without leak.

Dismantling and Refixing of Flow meters/Control Valves/Valves: Work involves: Arrange necessary tools and tackles for the work. Dismantling the valves/flow meter from position and fixing back in position with new gasket and servicing without leak. The transportation of valves/flow meter for cleaning & servicing are in scope of contractor. In case the valve is found damaged as inspected and confirmed by Engineer-in-Charge, collect and transport spare valve from workshop/store as instructed by Engineer-in-Charge, and fix it in position with new gasket and servicing without leak and transport the damaged valve to Workshed for servicing or Scrapyard. Size ranging from 100 NB to 300 NB.

Reclamation of usable flanges: Work involves: Reclamation of old and usable flanges from scrap pipes by cutting, welding and grinding, transporting to workshop for machining and transporting it back to the plant. Size ranging from 50 NB to 300 NB.
