Heads – Pressure Vessel Components for Tanks & Boilers

Overview

Heads are engineered pressure vessel components designed to close tanks, boilers, storage vessels, and industrial containers, ensuring system integrity, safe operation, and compliance with international standards.

Our Heads are manufactured with precision, high-quality materials, and strict adherence to industrial standards to meet the needs of oil & gas, chemical, petrochemical, power generation, and water treatment industries worldwide.

1️⃣ Types of Heads

We supply a comprehensive range of heads, including:

  • Elliptical Head (2:1) – Optimal for high-pressure vessels, providing uniform stress distribution.

  • Torispherical Head – Cost-effective and widely used in medium-pressure tanks.

  • Hemispherical Head – Suitable for high-pressure applications due to uniform stress handling.

  • Flat Head – Commonly used in low-pressure tanks and storage vessels.

  • Conical Head – Ideal for gravity-fed systems and hopper tanks.

  • Custom-formed Heads – Designed and fabricated according to project drawings and specifications.

2️⃣ Standards Compliance

Our heads are manufactured in compliance with major international standards:

Standard Applicable Heads
ASME Section VIII Pressure vessel heads for tanks, boilers
EN 13445 European standard for unfired pressure vessels
DIN / JIS Optional European & Japanese projects
GOST 14249 / GOST 15150 Russian standard for pressure vessel heads
Custom Standards Available upon request to meet project requirements

Ensuring compliance with these standards guarantees reliable performance under various industrial pressure conditions.

3️⃣ Materials & Grades

Available materials for heads include:

  • Carbon Steel – ASTM A516 Gr.70, ASTM A516 Gr.60

  • Stainless Steel – ASTM A240 WP304 / WP316

  • Alloy Steel – ASTM A387 / ASTM A516, for higher temperature/pressure applications

Our material selection ensures mechanical strength, ductility, and long service life under challenging industrial conditions.

4️⃣ Sizes & Forming Methods
