Product Introduction
Stainless steel heads can be classified into several types based on their geometric shapes, including spherical, elliptical, disc-shaped, spherical crown shaped, conical shell, and flat cap. Among them, spherical, elliptical, disc-shaped, and spherical crown shaped heads are collectively referred to as convex heads. These heads are connected to the cylinder by welding and are used for various container equipment such as storage tanks, heat exchangers, towers, reactors, boilers, and separation equipment.
In addition, the nominal diameter, also known as the average outer diameter, of stainless steel heads refers to the standardized standard diameter, expressed in DN and measured in millimeters. For example, the nominal diameter of a container with an inner diameter of 1200mm is marked as DN1200. The mold design of stainless steel head is also an important part of the production process. The mold should avoid small holes, narrow grooves, and angles, and the shape should be as symmetrical as possible to ensure the quality and performance of the head.

Material Selection
The materials of stainless steel heads include carbon steel (such as A3, 20 #, Q235, Q345B, 16Mn, etc.), stainless steel (such as 304, 321, 304L, 316, 316L, etc.), alloy steel (such as 15Mo3, 15CrMoV, 35CrMoV, 45CrMo, etc.), aluminum, titanium, copper, nickel, and nickel alloys. The selection of these materials depends on the specific usage environment and requirements.

Production Steps
When making stainless steel heads, a series of steps are required, including measuring the outer circumference of the head, dividing the outer circumference of the head into four equal parts, positioning welding, and welding after completing the positioning points. The maintenance of the head is also very important, including drying after hydrostatic testing, avoiding acid washing with reducing acid, complying with medium compatibility regulations, timely cleaning of welds and surface treatment, preventing surface scratches and bumps, avoiding direct contact with carbon steel, and not storing in the open air to prevent rain.
