Stamped covers are metal covers manufactured through a stamping process, widely used as sealing or head components in equipment such as boilers, pressure vessels, and tankless water tanks.
The manufacturing process typically includes steps such as blanking, stamping, trimming, and drilling. The material is mostly stainless steel or galvanized steel to ensure corrosion resistance and high-temperature resistance. The main types of stamped covers include convex, conical, and flat shapes, with various specifications, diameters ranging from 200mm to 9000mm, and wall thicknesses typically from 3mm to 14mm. Specific dimensions can be customized according to requirements. This product is highly favored in the industrial field due to its high structural strength, good sealing performance, and long service life. When selecting stamped covers, factors such as working pressure, temperature, and media corrosivity must be considered to ensure their applicability and safety. Furthermore, the production of stamped covers must comply with relevant industry standards, such as GB/T 25198-2010 "Pressure Vessel Heads," to guarantee product quality and performance.
