The steel tank heads are formed for welded installation on vertical or horizontal industrial tanks. Depending on the vessel design, the head may be elliptical, torispherical, hemispherical, conical, or another specified profile. Carbon steel, stainless steel, alloy steel, and selected special materials can be processed after forming conditions are confirmed. Spinning is useful for large or non-standard diameters, while regular sizes may be hydraulic-pressed. Control focuses on diameter, depth, roundness, straight-flange geometry, and edge condition so the head fits the shell with less correction during assembly.

The EHA values are reference examples for a 2:1 elliptical option. Other tank-head geometries use different dimensions, so final sizes and edge allowances follow the approved drawing.
Main Applications
• Oil, water, chemical, and general storage tanks in vertical or horizontal layouts.
• Buffer vessels, fire-water tanks, pressure-stabilizing tanks, and process containers.
• Fabricated tanks for energy, environmental, municipal, and machinery projects requiring steel tank heads with drawing-based dimensions.
Our Factory
Changhui operates stamping and cold/hot spinning lines supported by cutting, shaping, grinding, beveling, welding, non-destructive testing, and material-analysis equipment. Its hydraulic presses include 1200T, 1000T, 500T, and 315T units, with separate spinning equipment for larger and irregular work. The production route can therefore be matched to the actual tank design.
FAQ
Q: What details are needed for a tank-head order?
A: Send the tank inside diameter, head shape, material grade, nominal thickness, straight-flange length, quantity, standard, and inspection requirements.
Q: Can steel tank heads be supplied for replacement work?
A: Yes. Existing dimensions or a verified drawing can be used, but the mating shell size and edge condition should be checked before production.
Q: Can edge preparation be included?
A: Trimming and beveling can be arranged when weld-joint details are defined on the drawing.
