One of GT7 factory directions is manufacturing of flat dish ends (bottoms) on the customer's specifications.

Our company produces flat dish ends from stainless and alloy steel as well as from aluminum. Flat bottoms are less common than spherical or elliptical. However flat bottoms are used in  manufacturing of tanks, vessels and devices with low operating pressure not exceeding 0.4 bar. The working medium in such equipment is a neutral or aggressive liquid, explosive or toxic mixture. Additionally, flat bottoms are used in boilers, working under pressure.

Flat bottoms can also be used as baffles in tanks . They are also used as the heat exchanger tube sheets for oil refineries, power capacitors, boilers.

High quality and reliability of our flat bottoms is achieved through years of experience, modern equipment, highly skilled staff and compliance with all the European regulations in machinery manufacturing.
