Supplying Products for Various Different Types of Plant

In addition to being Japan's leading constructor of thermal and nuclear power plants, Taihei Dengyo has also accumulated extensive experience in various types of plant including chemical plants and others. The Saitama Plant provides fundamental support for this work and the associated technology. Since it was established in 1976, the Saitama Plant has been a supplier of various different industrial products and has put those functions to full use as a site for staff training and for research and development of welding techniques.
Based on rigorous quality management that covers everything from design to manufacturing and final testing, the Saitama Plant delivers highly reliable products that accurately meet the needs of many different plants.
The motto of the Saitama Plant is "doing our best while aiming for perfection".

Verification Testing of New Techniques Developed In-House

Taihei Dengyo has made a significant contribution to safety and energy efficiency through the development of a steady stream of new techniques, including a world-first boiler furnace scaffolding system for use in boiler maintenance, and the Taihei Jack System and Ultra Heavy Lifter for the automatic raising and lowering of heavy loads. The Saitama Plant takes great care to perform various different verification tests on these systems before they are put into actual use, including installing test facilities for these systems within the plant.
