“Column erection and heavy equipment lifting for refineries, fertiliser, chemical and petrochemical plants. Owned crane fleet 200 MT, 100 MT, 50 MT and 20 MT plus tie-ups with India's leading heavy lift suppliers.”
“Yes. HAIL is a specialist Turnkey EPC and LSTK contractor for Oil & Gas, Refinery, and Fertilizer sectors. We provide end-to-end solutions including FEED, Detail Engineering, Procurement, Construction, and Pre-Commissioning with single-point liability.”
“As a Static Equipment specialist, HAIL fabricates ASME U-stamp Heat Exchangers, Process Reactors, Distillation Columns, Separators, and Pressure Vessels in Stainless Steel (SS), Duplex, and Alloy Steel.”
“HAIL has major operations in Jamnagar, Dahej, Hazira, Mundra, and Vadodara. We serve the entire Oil & Gas belt with fabrication and EPC services pan India, have delivered overseas in Nepal, and actively tender in the UAE and wider GCC.”
“Yes. HAIL specializes in complex Brownfield Revamps and Shutdown Maintenance within live Refineries and Petrochemical plants, ensuring Zero-Incident Safety and time-bound delivery.”
“HAIL offers comprehensive EPC and mechanical services spanning storage tanks, pressure vessels, cryogenic tanks, LPG bullets, column erection, piping (3LPE), plant dismantling, structural steel, B2B fabrication job work, railway & metro coach fabrication, aerospace GSE tooling, and specialized EPC contracts for petrochemical, chemical, pharma, power, fertilizer, and green hydrogen plants.”
“Yes. HAIL is a single-source mechanical EPC contractor handling all disciplines — civil, mechanical, electrical, and instrumentation — under one contract with one safety regime, one schedule, and one liability. This eliminates the interface gaps that delay multi-vendor projects.”
“HAIL serves Oil & Gas, Refineries, Petrochemical plants, Fertilizer facilities, Chemical plants, Power plants, and Pharmaceutical manufacturing. Key clients include IOCL, BPCL, HPCL, Reliance, Nayara Energy, Thyssenkrupp, GSFC, GNFC, IFFCO, and other leading industrial players.”
“HAIL carries depth across multiple service areas that most Indian contractors cannot match under one roof — tanks, vessels, columns, piping, dismantling, structural, coatings, precision rolling stock/aerospace fabrication, and E&I. Combined with 42+ years of leadership experience, 2,000+ tanks built, ASME/API/PESO certifications, and a consortium with RINA Consulting for third-party quality assurance.”
“Ammonia remains adsorbed in insulation, weld pores and vapour spaces even after the tank is emptied. Risks include toxic exposure (IDLH 300 ppm), flammability above 16% in air, brittle fracture during cold-tank warm-up (-33 °C inner shell), high-elevation cutting on 30 m double-wall geometry, and contaminated insulation handling.”
“Reverse jacking lifts the shell with synchronised hydraulic jacks so each ring is cut at ground level instead of at 25–30 m height. It eliminates ~90% of working-at-height man-hours, removes the need for full external scaffolding (~600 MT material avoided), shortens the schedule by 35%, and gives much better vapour control during cutting.”
“Yes. HAIL is executing reverse-jacking dismantling of a double-wall ammonia tank plus a 55-metre flare stack at Birla Copper Ltd., Dahej for Ostwal Phoschem (India) Ltd. — with a zero-incident, zero-LTI HSE record. This makes HAIL the first Indian contractor to apply reverse jacking on ammonia.”
“Even after liquid drain-down, a 30 m ammonia tank typically holds 50–200 kg of residual NH3 adsorbed in the insulation, weld pores, vapour space and bottom seal.”
“HAIL provides full-scope mechanical and EPC services for chemical plants including acid storage tanks, chemical reactors, pressure vessels, process piping in exotic alloys, structural steel, heat exchangers, column erection, and corrosion-resistant fabrication in SS 316L, duplex, Hastelloy, rubber-lined CS and FRP-lined equipment. We serve phosphoric acid, chlor-alkali, methanol, formaldehyde, caustic soda and specialty chemical plants across India.”
“We fabricate chemical process equipment in SS 304/316/316L, duplex 2205, super duplex 2507, Hastelloy C-276, Inconel, titanium, rubber-lined carbon steel, FRP-lined tanks, and PTFE-lined piping. Material selection is driven by the specific chemical service — acid type, concentration, temperature and chloride content. Every joint is PMI-verified with full traceability.”
“Yes. HAIL delivered a turnkey phosphoric acid storage tank project for Krishna Phoschem at Jhabua, Madhya Pradesh — covering civil foundations, tank fabrication and erection for concentrated phosphoric acid service. We also executed ammonia tank dismantling at Dahej for Ostwal Phoschem (India) Ltd, which operates in the phosphoric acid value chain.”
“It depends on the product, concentration, temperature and chloride content. As a starting point: SS 316/316L for phosphoric acid and pharmaceutical intermediates; duplex for aggressive chlorides; rubber-lined carbon steel for hydrochloric and dilute sulphuric acid; FRP-lined carbon steel for concentrated acids, alkalis and solvents. We confirm the final choice against your process data.”
“Yes — a 19.5 m diameter × 12.6 m high phosphoric acid storage tank for Krishna Phoschem Ltd. at Jhabua, Madhya Pradesh, delivered turnkey from the RCC tank pad foundation through engineering, fabrication, erection and welding.”
“API 650 and IS 803 for vertical atmospheric tanks, API 620 for low-pressure tanks, and ASME Section VIII for pressure storage, built under our ASME U-Stamp with PESO SMPV(U) licensing where it applies.”
“Yes. We deliver chemical tanks turnkey, including the RCC tank pad or ring-wall foundation, so foundation and tank are designed and built under one contract.”
“350+ tons at 60-metre height inside a live refinery. Each critical lift carries an engineered lift study, GBC assessment and rigging plan.”
“Yes — 200 MT, 100 MT, 50 MT and 20 MT. For super-heavy lifts we have tie-ups with India's leading suppliers.”
“Columns, reactors, regenerators, exchangers, drums, modules, flare stacks and structural steel.”
“Yes — under PTW with full HSSE and operating-unit interface; we have done it at IOCL Barauni and IOCL Gujarat.”
“Yes — ground bearing, rigging gear, 3D crane studies, JSA, weather criteria and HSE briefing pack are part of every critical lift.”
