Stainless Steel Wall Cap is an indispensable and important part of pressure vessel equipment in petrochemical, atomic energy to food and pharmaceutical industries. The cylinder is connected by welding. It can be divided into spherical, elliptical, dish-shaped, spherical cap, conical shell and flat cover, among which spherical, elliptical, dish-shaped and spherical cap heads are collectively called convex heads. In welding, it is divided into butt welding head and socket welding head. Used in various container equipment such as storage tanks, heat exchangers, towers, boilers and separation equipment. The quality of the head is directly related to the long-term safe and reliable operation of the pressure vessel.
