Torispherical Head

Overview

Torispherical Heads are high-performance pressure vessel components designed to close tanks, boilers, and industrial storage vessels. Their spherical crown with a knuckle radius allows efficient distribution of internal pressure, making them a cost-effective solution for medium-pressure vessels.

Manufactured with precision and in compliance with international standards, our Torispherical Heads deliver reliability, durability, and operational safety for demanding industrial environments worldwide.

Product Features

  • Optimized Stress Distribution: Spherical crown and knuckle radius provide excellent resistance to internal pressure.

  • Material Excellence: Available in Carbon Steel, Stainless Steel, and Alloy Steel, ensuring corrosion resistance and mechanical strength.

  • Wide Size Range: DN15 – DN4000 (custom sizes available).

  • Forming Methods: Cold forming or hot forming to achieve required thickness and dimensional accuracy.

  • Custom Fabrication: Can be manufactured to client drawings or project specifications.

Standards Compliance

Our Torispherical Heads are produced according to global standards:

  • ASME Section VIII – Pressure vessel heads

  • EN 13445 – European unfired pressure vessel standard

  • DIN / JIS – Optional for European & Japanese projects

  • GOST 14249 / GOST 15150 – Russian standards for pressure vessel heads

  • Custom Standards – Available upon request

Compliance ensures safe operation under medium to high pressure in industrial applications.

Materials & Grades

  • Carbon Steel: ASTM A516 Gr.70 / Gr.60

  • Stainless Steel: ASTM A240 WP304 / WP316

  • Alloy Steel: ASTM A387 / other high-temperature/pressure grades

Carefully selected materials provide mechanical strength, ductility, and long-term reliability.
