Larsen & Toubro Limited is a leading engineering, construction and technology company with global operations, and turnover exceeding USD 4 billion. Its interests also cover end-to-end solutions in Information Technology.

The Company's operations are characterized by its customer-focussed approach, an obsession with quality, and strong international linkages.

L&T has a global spread of offices and works closely with leading international consultants, process licensors, technology partners and quality certification agencies. The Company has exported critical heavy engineering equipment to over 45 countries including U.S.A., U.K., France, China and Australia. Engineering and construction projects have been executed in the Middle East, Africa, the sub-continent and South East Asia.

In the domestic market, L&T has established dominant leadership in most of its major businesses. With design and manufacturing bases in major cities, a countrywide network of offices supplemented by a tier of dealers, the Company enjoys an image and equity in virtually every district of India.

L&T's Heavy Engineering Division (HED) has established a reputation for quality products in the global market with its strong engineering capabilities and state-of-the-art manufacturing facilities. The Division manufactures and supplies precision, custom-engineered critical static process plant equipment & systems such as reactors, gasifiers, pressure vessels, columns, high-pressure exchangers to core sector industries like Fertilizer, Refinery, Petrochemical, Chemical, Oil & Gas, Power, Aerospace, and allied Strategic sectors.

The Division’s manufacturing facilities are located at Mumbai in Maharashtra, and near Surat & Baroda in Gujarat.

The Division has achieved a 'preferred supplier' relationship with major EPC contractors and has been recognised as the 'Most Valuable Supplier' by Fluor Corporation of USA, a major EPC contractor. Key customers have recognised the quality and on-time delivery performance of the Division by awarding prestigious orders for Reactors on 'Nomination' basis.

Key success factors for significant growth in export performance include close interaction with customers, reliable performance, improved planning for timely execution of orders and positioning the Company as a reliable, long-term partner.

The Company

The evolution of Larsen & Toubro Limited is one of the most remarkable success stories in industry. The Company owes its name, origin and history of achievements to two Danish engineers, Henning Holck-Larsen and Soren Toubro. They came to India and in 1938 set up a small partnership firm in south Mumbai. Adopting international standards in its operations and value systems, the Company grew rapidly to become a leading engineering and construction organization. Today, L&T has offices around the world, including Copenhagen, Denmark, the city from where Holck-Larsen and Soren Toubro set off on their journey to the east.

L&T's world-class fabrication capabilities have been achieved through perfect integration of efficient material handling & preparation, precision machining and welding processes for a range of material in varying thicknesses, backed by technological excellence in design & engineering and responsive quality systems.

Fabrication : World Class

Material Handling & Preparation

The plate material on receipt and inspection is stamped with specific codes and is kept in assigned enclosures ensuring that there is no intermixing of materials or any inter-material storage contamination.

The plates are cut on CNC flame/plasma cutting machines; edges are prepared on an edge planer and rolled on heavy duty bending rolls capable of rolling 125mm and 250mm thick plates in cold and hot conditions respectively.

A ring frame type 1000-tonne hydraulic press with a movable ram and table is used for plate forming.

CNC Flame / Plasma Cutting MachinePlate Size : 21m x 5.3mPlate Thk : C.S. - 300mm : S.S. - 150mm

Plate Rolling MachinePlate Size : 4500mm wide Plate Thk : Hot - 250mm : Cold - 125mm

Multi-wall Vessels

To combine the corrosion resistance properties of certain materials with mechanical strength of others, multi-wall vessel fabrication technology is used.

Heating facilities are extensively used to manufacture multi-wall vessels through shrink-fitting.

The Company

The evolution of Larsen & Toubro Limited is one of the most remarkable success stories in industry. The Company owes its name, origin and history of achievements to two Danish engineers, Henning Holck-Larsen and Soren Toubro. They came to India and in 1938 set up a small partnership firm in south Mumbai. Adopting international standards in its operations and value systems, the Company grew rapidly to become a leading engineering and construction organization. Today, L&T has offices around the world, including Copenhagen, Denmark, the city from where Holck-Larsen and Soren Toubro set off on their journey to the east.
