Dished Head Production

Dished Head Production: An Essential Component for Pressure and Non-Pressure Vessels

Dished heads are critical components used to close the bottoms and tops of pressure and non-pressure vessels in the industrial sector. They are preferred in many industrial applications such as LPG, LNG, fuel, food, autoclaves, and reactors to enhance durability and ensure safety.

Applications of Dished Heads

Dished heads are primarily used to improve the strength of cylindrical vessels and ensure uniform pressure distribution. The most common applications are:

✅ Pressure Vessels: LPG, LNG, chemical tanks, reactors, autoclaves
✅ Storage Tanks: Fuel, food, and industrial liquid tanks
✅ Industrial Applications: Steam boilers, heat exchangers, and other high-temperature applications

Advantages of Dished Head Usage

🔹 Durability and Pressure Distribution
Dished heads ensure better hydraulic pressure resistance on radial surfaces.
Homogeneous pressure distribution minimizes material fatigue and deformation.

🔹 Welding Safety and Leak Prevention
The design of the dished head moves the weld seams away from critical sections, enhancing sealing and safety.

🔹 Variety of Material Options
Dished heads can be manufactured from various materials such as carbon steel, stainless steel, and alloy steels.

🔹 Long Service Life and Low Maintenance Costs
The design’s resistance to wear and fatigue extends its lifespan and reduces maintenance requirements.

Dished Head Production Process

1️⃣ Material Selection and Cutting
Steel sheets suitable for the intended application are selected and cut to the required dimensions.

2️⃣ Shaping (Pressing or Forging)
The steel sheets are shaped into the dished form using hot or cold forming methods.

3️⃣ Heat Treatment and Stress Relief
Special heat treatment processes are applied to enhance material durability and reduce internal stresses.

4️⃣ Welding and Surface Finishing
The dished head is welded onto the vessel body, and surface finishing operations are completed.

Dished Head production is a critical process in ensuring the safety and longevity of pressure and non-pressure vessels in industrial sectors. With advantages such as uniform pressure distribution, high strength, and welding safety, dished heads are indispensable components used across industries.

High-quality dished heads, produced for each sector’s specific needs, form the foundation for safe transportation and storage processes.
