Reactor made from chrome molybdenum steel for
the Republic of Trinidad and Tobago

Hitachi Zosen is a of the leading manufacturer of pressure vessels and heat exchangers for refineries, petrochemical plants, fertilizer plants, and industrial plants such as seawater desalination plants and pulp plants. We contribute to meeting the ever-increasing demand for world energy by supplying reactors to the Refinery Upgrading Project, which produces gasoline and diesel oil from heavy crude oil sand projects and gas-to-liquid projects and among others. In addition, we contribute to securing food and water for growing populations in developing countries by supplying equipment to fertilizer plants and desalination plants.
On March 21, 2012, Hitachi Zosen has started ISGEC Hitachi Zosen Limited through joint funding with ISGEC Heavy Engineering Limited (ISGEC Ltd.), a major Indian manufacturer of process equipment.
With transferring the expertise of our Ariake Works in Japan to this joint venture and accelerating our sales promotion through the sales-network of ISGEC Ltd. for valuable customers in India, we believe firmly to expand the business field in the Indian market and to satisfy our customers.
Moreover, we are confident of supplying high quality process equipment from this joint venture with competitive price to world market as well.

Non-destructive testing (NDT) Services

We supply the phased array ultrasonic testing (PAUT) system to
tube-to-tubesheet welds of heat exchangers, and it is performed by the fully automatic scanning. Furthermore, we consider to customize our equipment to focus on the clients’ need to find defects (e.g. cracks and/or corrosion).
