Dipesh Engineering Works

What Dipesh Engineering Works does

Dipesh Engineering Works, founded in 1981 and headquartered in Mumbai, designs and manufactures standard-based coded process equipment and turnkey process plants for global clients in chemicals, petrochemicals, pharmaceuticals, oil & gas, power, aerospace, fertilizers, and related process industries. Its core product portfolio includes reactors and agitators (Standard, C-GMP, cladded, and exotic-material variants), pressure vessels, shell-and-tube and specialized heat exchangers, distillation columns, hydrogenators, storage tanks, mixers/dryers/rotary equipment, evaporators, piping, skid-mounted systems, autoclaves (industrial and aerospace-grade), and complete turnkey process plants. Manufacturing is anchored in four Maharashtra-based facilities (Mumbai HQ plus Ambernath I, Ambernath II, and Tarapur/Manor III) spanning 14,000+ square meters with 130-ton lifting capacity and a 15m x 6m x 6m clean room for exotic-metal fabrication (Titanium, Tantalum, Zirconium). The company is ASME U, U2, R, NB certified with PED approvals and operates a 35-person in-house design team using Ansys, Aspen One, PV-Elite, CAESAR-II, HTRI, and Siemens Solid Edge.

The business model is engineered-to-order, project-based manufacturing with one-time revenue per contract rather than recurring licensing or service streams. Sales are driven by direct enterprise engagement with engineering procurement teams at large industrial customers (Lanxess, Indian Oil Corporation, ONGC, BPCL, Siemens, Alstom, Eskom, Aditya Birla Petrochemical, RCF, FACT), supplemented by pre-qualification relationships with global third-party engineering consultants (Jacobs, ThyssenKrupp, Engineers India Ltd, Aker Solutions, Technip, NNE Pharma) and inspectors (Bureau Veritas, LRA, SGS). The company serves both domestic Indian customers and exports to Singapore, South Africa, and other geographies. Under chairman Jayantibhai B. Patel and CEO Ketan J. Patel, group revenue scaled from INR 6 million to a stated INR 1 billion with a workforce of 650+ employees. Dipesh Engineering Works is part of the J.B. Patel Group of Companies, alongside sister concern Unique Chemoplant Equipments (aerospace autoclaves) and subsidiary Suketu Organics Pvt Ltd (specialty chemicals and electrical insulation).
