Torispherical heads close tanks and vessels, including equipment designed for pressure service. Cold forming and flanging establish the profile. Material, size, radii and thickness are selected through the equipment design and manufacturing review.
Torispherical head forming
Manufacturing requirements consider GOST 34347-2017 and GOST 34233.2-2017.
Design review covers vessel volume, contents and operating conditions. Cold forming is used to manufacture Torispherical heads for oil and gas, chemical, process and fire water equipment. Catalogue diameters span 600–4200 mm. Heat treatment and weld inspection methods are included where specified by the material, project and agreed inspection plan.
Types
Torispherical heads are listed in three configurations:
- Type A. For Type A, crown radius equals internal diameter. The catalogue straight flange guide is at least 3,5 times thickness; the final dimension follows the drawing. The overall source range lists thickness 3–22 mm, with actual combinations confirmed in the size cards.
- Type B. Straight flange height follows the agreed drawing. The crown radius is 0,9 of the internal diameter, within the listed range 1000–3600 mm;
- Type C. This profile uses a crown-radius-to-internal-diameter ratio of 0,8.
