A516 Gr70 Flat Dish Head

Henan Bebon Iron & Steel Co., Ltd. is a professional head manufacturer. We can produce and design various heads according to customer requirements.
Classification by shape and application:
Standard Type
Elliptical Heads (EHA/EHB): Most commonly used, suitable for medium and low-pressure vessels, cost-effective.
Dish Heads (THA/THB): The transition area has a radius, and the compressive strength is slightly weaker than elliptical heads.
Hemispherical Heads: High pressure/extreme conditions (such as nuclear power), but the cost is higher.
Flat Heads (Flange Heads): Atmospheric or low-pressure vessels, easy to clean (food industry).
Special Type
Conical Heads: Used for tapered/diffuser sections (such as sedimentation equipment).
Flanged Heads: Facilitates pipe connection and reduces welding.
Customized Special-Shaped Heads: Non-standard design (drawings or 3D models need to be provided).
Material Selection Recommendations
Carbon Steel (Q235B, Q345R): General-purpose, low cost, requires anti-corrosion treatment.
Stainless Steel (304, 316L): Corrosion-resistant, the first choice for the food/pharmaceutical industry.
Duplex Steel (2205): High strength and resistance to chloride corrosion (seawater environment).
Nickel-based Alloy (Hastelloy): Strong acid/high-temperature environment (chemical extreme conditions).
Composite Materials: Lined heads (such as titanium lining) are used for strong corrosive media.
