Project Overview
Project Overview
Vardhaman Infra was commissioned to handle the design and installation of industrial plumbing networks and a comprehensive fire hydrant system for the Chambal Fertilisers and Chemicals Limited plant expansion at Gadepan in Kota district. This large-scale industrial project required engineering solutions capable of withstanding the demanding conditions of a fertiliser manufacturing environment, including high temperatures, chemical exposure, and continuous 24/7 operations.
Chambal Fertilisers, one of India’s leading fertiliser producers, required a partner with proven expertise in industrial MEP systems. Vardhaman Infra’s track record in Rajasthan’s industrial corridor made us the natural choice for this critical infrastructure expansion.
Scope of Work
- Industrial Plumbing Networks: Design and installation of process water supply lines, cooling water circulation systems, DM (demineralised) water piping, and effluent drainage networks for the new production units.
- Fire Hydrant System: A complete external fire hydrant ring main with hydrant valves at strategic locations, fire pump house with diesel and electric pump sets, underground fire water storage tanks, and monitor nozzles for high-risk zones.
- Utility Piping: Compressed air distribution, steam condensate return lines, and chemical dosing piping for the water treatment plant expansion.
- Testing and Commissioning: Hydrostatic testing of all pipelines, flow testing of fire hydrant system to NFPA standards, and performance validation of pump sets.
Technical Challenges and Solutions
The primary engineering challenge was designing plumbing systems that could handle the corrosive nature of chemicals present in a fertiliser plant. Standard GI and MS piping would have failed within months. Our engineering team specified SS 304L and SS 316L stainless steel piping for chemical-contact lines, HDPE piping for effluent drains, and epoxy-lined MS piping for fire water mains to prevent internal corrosion and ensure a 25-year service life.
Another significant challenge was executing hot work (welding, cutting) in proximity to operational process units containing flammable materials. Vardhaman Infra implemented a rigorous hot work permit system, deployed fire watch personnel during all welding activities, and scheduled critical tie-ins during planned plant shutdowns to eliminate safety risks.
The fire hydrant system design had to account for the plant’s large footprint and varying risk classifications. We conducted a detailed fire risk assessment and hydraulic calculations to ensure adequate water flow and pressure at the most remote hydrant point, even during a simultaneous two-hydrant operation scenario as mandated by the Petroleum and Explosives Safety Organisation (PESO) guidelines.
Materials and Methods
Piping materials included SS 316L from Jindal Stainless for corrosive service, Tata Steel ERW pipes for fire mains, and Supreme HDPE pipes for effluent lines. Fire pumps were Kirloskar make — one 2,500 GPM electric pump and one 2,500 GPM diesel pump — ensuring redundancy. All welding was performed by ASME-qualified welders, and every weld joint on critical lines underwent radiographic testing (RT) for quality assurance. Pipe supports and hangers were designed per MSS SP-58 standards.
Timeline, Team, and Execution
The project spanned 14 months with a peak workforce of 120 personnel including pipefitters, welders, riggers, and safety officers. Vardhaman Infra deployed a full-time site safety officer given the industrial hazard environment. Daily toolbox talks, weekly safety audits, and compliance with OISD (Oil Industry Safety Directorate) standards ensured zero lost-time incidents throughout the project duration — a milestone achievement in an active industrial plant environment. Material tracking was managed through a barcode-based inventory system at the site fabrication yard, ensuring traceability of every pipe spool from material receipt to installation and testing.
Coordination with Chambal Fertilisers’ operations team was critical throughout the project. Weekly interface meetings addressed scheduling of tie-in activities, isolation requirements, and any modifications needed to accommodate changes in the plant’s operational schedule. Vardhaman Infra’s flexibility in adjusting work sequences to accommodate unplanned shutdowns and schedule changes was a key factor in maintaining the overall project timeline without compromising safety or quality standards.
Results and Client Satisfaction
The fire hydrant system achieved the designed flow rate of 2,500 GPM at 7 kg/cm² residual pressure at the most remote hydrant, exceeding the minimum NFPA and TAC (Tariff Advisory Committee) requirements. All plumbing systems passed hydrostatic testing at 1.5 times the working pressure with zero leakage. Chambal Fertilisers’ project management team commended Vardhaman Infra for the zero-incident safety record and on-time completion, leading to our empanelment for future maintenance and expansion contracts at the Gadepan facility.
Key Takeaways
This project established Vardhaman Infra’s credentials in heavy industrial plumbing and fire protection systems. The experience of working within an operational fertiliser plant — with its stringent safety protocols and material specifications — has become a cornerstone of our industrial project portfolio. It demonstrated that safety, quality, and schedule adherence are not mutually exclusive, even in the most challenging industrial environments. The knowledge of industrial piping codes, material selection for corrosive environments, and the discipline of working under OISD and PESO frameworks has become a lasting competitive advantage for Vardhaman Infra in the industrial MEP segment.
