Why fertilizer plants need a specialist mechanical contractor
Fertilizer manufacturing involves some of the most demanding process conditions in Indian industry — cryogenic ammonia at minus 33 degrees Celsius, high-pressure synthesis loops at 200+ kg/cm2 in urea plants, corrosive phosphoric acid and sulphuric acid handling in DAP facilities, and abrasive slurry service in granulation and prilling circuits. A general mechanical contractor without fertilizer-specific experience will struggle with the metallurgy requirements, the hazardous material handling protocols and the tight turnaround schedules that fertilizer complexes operate under. HAIL brings proven capability across every mechanical discipline the fertilizer industry requires: ammonia tank construction and decommissioning (we are India's first reverse-jacking ammonia contractor), pressure vessel fabrication per ASME Section VIII, high-pressure alloy piping per ASME B31.3, structural steel, heavy equipment erection with our owned 200 MT crane fleet, and complete pre-commissioning support. Our client list reads like a roster of India's fertilizer industry.

Ammonia tank construction and decommissioning
Ammonia storage is the most critical and hazardous asset in any fertilizer complex. HAIL has specialist capability in both construction and decommissioning of ammonia storage tanks — a rare combination in the Indian market.
- Ammonia tank construction: refrigerated atmospheric ammonia tanks per API 620 Appendix R with 9% nickel steel inner tank, carbon steel outer tank, perlite insulation, pressure/vacuum relief systems, ammonia vapour recovery and complete instrumentation. Also pressurised ammonia bullets per ASME Section VIII for smaller storage requirements.
- Ammonia tank decommissioning: HAIL is India's first contractor to execute ammonia tank decommissioning using reverse-jacking methodology. Complete scope: gas-freeing and purging, controlled atmosphere cutting, sectional dismantling from top to bottom, scrap segregation and environmental compliance. Reference: Birla Copper ammonia tank dismantling at Dahej for Ostwal Phoschem (India) Ltd. See our dedicated ammonia tank decommissioning page.
- Cryogenic ammonia systems: for refrigerated ammonia storage at minus 33 degrees Celsius, we work with cryogenic-grade materials (9% nickel, austenitic SS) and controlled welding procedures. See our cryogenic tank construction capability.
