Tema India

What Tema India does

Tema India Pvt Ltd, founded in 1984 (with roots in predecessor Leo Engineering Works established by Haresh Sippy in 1975), is a privately-held Indian process equipment manufacturer headquartered in Mumbai. The company designs and fabricates bespoke high-pressure heat exchangers, pressure vessels, reactors, columns and towers, condensers, feedwater heaters, and piping components for extreme service conditions (high pressure, high temperature, severe corrosivity, hazardous media). Its proprietary Screw Plug Heat Exchanger line — marketed as SRX — is built around an Indian-patented Shrink Ring technology (granted 2009) that addresses bell-mouthing and thread-galling failure modes common in breech-lock exchanger designs; over 160 such units have been installed globally without operational failure. The company operates three manufacturing facilities near Mumbai and Vadodara with a combined installed capacity of 15,000 metric tons per annum, including a flagship Achhad plant with 400MT lifting capacity and a 5,000 sqft clean room.

Tema India serves enterprise customers across oil & gas (refining, FPSO/FLNG), petrochemicals, fertilizers, nuclear power, conventional power, specialty chemicals, polysilicon, and hydrogen — with approximately 80% of revenue derived from exports across 27+ countries. The company sells directly to end users and through relationships with major EPC contractors and process licensors (KBR, Toyo, Stamicarbon, L&T, GS E&C). Revenue is project-based on custom quotations tied to metallurgical specification, pressure/temperature rating, and delivery timeline; an after-market services stream (predictive and preventive maintenance, tube bundle replacement, repair) supplements project fabrication. Notable credentials include ASME U/U2/U3/S stamps, ISO 9001/14001/45001/3834, PED 3.1, AD2000, and IBR certifications, and marquee contracts including 46 stainless-steel exchangers for Sasol's Lake Charles Chemicals Project (including the largest single exchanger the company has built at 248 MT / 20m), multiple Petrobras FPSO topside packages, and a Rs 1,600 crore consortium contract with ECIL for Kudankulam Units 5 & 6 control and instrumentation. The company is family-controlled, with founder Haresh Sippy as Chairman & MD and second-generation Akhil Sippy appointed CEO in 2023.
