A dished head, also known as a dish-shaped head, is a common type of pressure vessel head consisting of three sections: a spherical crown, a transition section, and a straight flange. Carbon steel and stainless steel dished heads typically range in price from tens to hundreds of yuan, depending on the diameter, thickness, and material.
Dished heads are essential components used to close pressure vessels, storage tanks, boilers, and industrial equipment. Jinhang Pipeline supplies dished heads in carbon steel, stainless steel, and alloy steel, with various shapes, diameters, and wall thicknesses to meet different project requirements.
Manufactured according to applicable standards and customer specifications, our dished heads can be customized by material grade, dimensions, and head geometry. Material selection and dimensional requirements can be confirmed according to the intended application, design code, and operating conditions.
