Our Services
Our own crews carry out piping, insulation, fire systems and heavy fabrication, so there's one accountable team from shop floor to site.
Applications
Our boilers pressure parts and fabricated equipment run inside any plant that needs steam, hot water or heavy steel, from dairies and rice mills to refineries and power stations.
How we work
Every job moves through four controlled stages. Scroll to watch a steam drum go from blueprint to finished steel.
DesignOur expert engineers design to the client's requirement and add innovations of our own: pressure calculations, GA drawings and IBR documentation.
We identify the resources and certified materials needed for the best outcome, then lock a schedule you can plan production around.
Once design and resources match the requirement, fabrication begins: welding, bending, NDT and hydro testing on our shop floor.
Our own crews erect, insulate and commission on site, then hand over a running system with complete inspection records.
Our Clients
From refineries and steel plants to dairies and sugar mills: a few of the 500+ clients our pressure parts and fabrication work runs for.

Testimonials
Plant heads, project managers and purchase teams on delivery, build quality and our site crews.
Sterling handled the complete retubing of our bagasse-fired boiler, from supply to erection and performance trials. Their site team was disciplined and the schedule was kept.
We source economiser coils and superheater elements from Sterling. Fabrication quality and IBR documentation have been in order every time, which makes inspection simple for us.
Our chimney work had to fit a tight shutdown window. Sterling planned the dismantling and erection carefully, followed safety throughout and handed over on time.
One vendor for the boiler, chimney, piping and insulation made our turnkey boiler house far easier to manage. Clear communication from design right through commissioning.
Areas we serve
From our MIDC Bhosari works we dispatch and erect across Maharashtra, Gujarat, Goa, Karnataka, Madhya Pradesh, Rajasthan, Chhattisgarh, Telangana and Andhra Pradesh.
Boiler pressure parts are the pressurised components that carry water or steam inside a boiler: superheaters, economizers, headers, waterwall panels, steam drums and coils. They are manufactured to IBR and ASME codes to safely withstand high temperature and pressure.
Yes. Our pressure parts are manufactured and inspected to IBR 1950 and ASME standards using approved materials, with hydro test, RT/UT testing and third-party / IBR certification.
A pressure vessel is a sealed container designed to hold gases or liquids at a pressure different from the ambient. Built to ASME Section VIII or IS 2825, vessels like reactors, receivers and storage tanks serve chemical, pharmaceutical, food and oil & gas industries.
An industrial MS chimney is a tall steel structure that safely discharges flue gases from boilers and furnaces to the atmosphere. Designed per CPCB emission norms and draft requirements, MS chimneys ensure proper combustion-gas dispersion and regulatory compliance.
A turnkey industrial project is a complete, ready-to-operate plant delivered by a single contractor handling design, fabrication, supply, erection, piping, insulation and commissioning. The client receives a fully functional system, such as a boiler house, without managing multiple vendors.
Sterling Engineers serves chemical, pharmaceutical, food processing, dairy, textile, paper, sugar and rice mills, oil & gas, rubber, automobile, power, cement and packaging industries: anywhere steam, hot water or fabricated industrial equipment is required.
Yes. Our crews have rehabilitated 56 TPH and 65 TPH sugar-mill boilers in Ethiopia and retubed an 80 TPH bagasse-fired boiler there. We have also supplied a 21 m self-supported chimney to Doha, Qatar.
We fabricate MS and SS industrial storage tanks from 1 KL up to 10,000,000 KL, for water, fuel oil and process fluids, with associated piping and structural work.
