Hermes-Ural manufactures top-quality spherical heads of various sizes from stainless steel. Products can also be manufactured on a custom basis, in accordance with the customer’s specifications.

Scope of application

Unlike an elliptical workpiece, a spherical head does not require flanging. This is why spherical heads can be used in the internal structures of pipelines. Besides that, they are widely used in pharmaceutics, power industry; and chemical and food processing industries.

Also, the spherical composition of products allows using them in architecture and design, improvement of household plots, and other areas. Non-flanged metal products are elements of cylindrical vessels and machines operating under low pressure or filling vessels (filter presses, fuel tanks, accumulators, tank trucks, etc.).

Features

These non-flanged products are manufactured by cold forming, and then thermally heated for greater strength. A non-flanged edge is attached to the tank by welding. The following materials are used in the manufacture:

The diameter of spherical products manufactured by our company can vary from 0.8 to 4.5 meters.
