Pioneering High-Pressure Boiler Engineering in Central India
Modern Boilers Pvt. Ltd. is an ISO 9001:2015 and IBR-certified engineering enterprise based in Nagpur. For over three decades, we have engineered zero-defect superheater coils, studded bed coils, economizers, water wall panels, and heavy pressure components for India’s premier thermal power, steel, cement, and chemical complexes.
Built on Three Decades of Uncompromising Metallurgical Integrity
Founded in 1992 in Nagpur by seasoned thermal engineers, Modern Boilers Pvt. Ltd. began with a clear industrial objective: eliminate catastrophic tube punctures and unplanned boiler outages through superior tube metallurgy and strict Indian Boiler Regulations (IBR) compliance.
What began as a specialized tube bending shop has evolved into an integrated manufacturing and turnkey maintenance power plant partner. Today, our 45,000 sq. ft. campus operates high-precision cold bending lines, specialized resistance stud welding for fluidized bed boilers, automated submerged arc welding, and dedicated radiographic testing chambers.
100% butt weld radiography & Form III-A certified witness testing.
Only prime carbon & alloy seamless tubes with original Form IV mill TC.
24-hour emergency site mobilization across Maharashtra & Central India.
Established manufacturing operations in Nagpur with official IBR repairer & fabricator authorization.
Constructed our 45,000 sq. ft. covered campus on Kamptee Road with 20-ton overhead EOT cranes and heavy cold bending bays.
Pioneered automated resistance stud welding for AFBC/CFBC bed coils and precision bending of ASME SA213 T91 superheater tubes.
Continuing to serve India’s largest conglomerates with 250 kg/cm² hydro-certified zero-defect pressure parts.
Advanced Machinery & In-House Testing Infrastructure
Every pressure part leaving our Nagpur workshop is fabricated on dedicated CNC hydraulic machinery and rigorously tested under direct IBR inspector supervision.
CNC Hydraulic Mandrel Benders
Precision cold bending for tube outer diameters from 25.4mm up to 101.6mm and wall thicknesses up to 12.5mm. Delivers ultra-tight bends down to 1.5D bend radius while maintaining strict IBR limits on tube thinning and ovality.
Automated Resistance Studding
Dedicated microprocessor-controlled stud welding stations designed specifically for AFBC & CFBC in-bed evaporator coils. High weld fusion strength prevents stud detachment during turbulent sand-bed combustion.
250 kg/cm² Hydrostatic Rig
Certified hydro-testing bay equipped with dual digital recording gauges, calibrated test manifolds, and automated pressure hold monitors. Every coil bundle and header is hydro-tested at 1.5x design pressure witnessed by IBR inspectors.
Radiography & Darkroom Lab
Dedicated shielded bunker for 100% butt weld radiography (RT), Ultrasonic Thickness Gauging (UT), and Liquid Dye Penetrant (DPT) inspections conducted by certified ASNT/ISNT Level-II technicians.
Post-Weld Heat Treatment (PWHT)
Calibrated electrical resistance and localized induction heating systems for preheating and PWHT of high-alloy steels (SA213 T11, T22, T91) to eliminate residual welding stresses and prevent stress-corrosion cracking.
20-Ton Overhead EOT Cranes
Heavy tandem overhead cranes spanning all fabrication and dispatch bays. Enables safe maneuvering of 15-meter long superheater pendants, membrane panels, steam drums, and heavy multi-flue industrial stacks directly onto low-bed trailers.
