Germes-Ural manufactures spherical heads in specified materials and sizes to the customer technical requirements.

Applications

Spherical unflanged heads have no straight flange and are used in specified piping, vessel and tank constructions. Applications include pharmaceutical, energy, chemical and food equipment, filters, thermal storage and fuel tanks, as well as architectural structures. Loads and suitability follow each project.

Features

Spherical head requirements are reviewed with reference to GOST 34233.2-2017 and 34347-2017. Cold forming establishes the profile; heat treatment is included where required by the material and project. The unflanged edge joins the shell through the specified weld. Materials include:

stainless steel;
clad steel;
carbon and other specified steels.

The spherical head diameter range is 100–4700 mm.

Our services

Germes-Ural reviews catalogue configurations and customer drawings to confirm manufacturing requirements.

Our equipment supports individual and batch forming in different sizes. We manufacture spherical heads, elliptical heads, torispherical heads and other head types for the specified installation, material and service conditions.

Components undergo the agreed quality checks before delivery. For an enquiry, call +7 (343) 264-81-23 or email info@germes-ural.ru
