tank heads formed to perform
Commercial Metal Forming manufactures ASME and non-code tank heads to your print. We form across a wide range of sizes and materials, then deliver weld-ready parts with the edge prep and documentation you specify.
asme tank heads
Built for pressure-rated performance, our ASME tank heads are manufactured in a wide range of profiles, diameters and thicknesses. Each head is formed to specification and delivered ready for fabrication, inspection or code stamping.
Commercial Metal Forming is also the only tank head manufacturer with ASME joggle capabilities up to 72″ OD x 3/8″ thick, allowing us to deliver precise, weld-ready fits for even the most demanding applications.
ASME 2:1 Elliptical Tank Heads
Outside Diameter: 4″–300″
Nominal Thickness: 16 GA–2″
Overview: The pressure-vessel standard, balancing strength and volume. Ideal for a broad range of code applications.
ASME Flanged & Dished Tank Heads
Outside Diameter: 4″–268″
Nominal Thickness: 16 GA–2″
Overview: Workhorse torispherical profile for code service; clean weld-ready geometry.
ASME 80-10 Flanged & Dished Tank Heads
Outside Diameter: 4″–300″
Nominal Thickness: 16 GA–2″
Overview: 80% dish radius / 10% knuckle radius; an efficient alternative where geometry or process favors 80-10.
ASME High Crown Tank Heads
Outside Diameter: 4″–300″
Nominal Thickness: 16 GA–2″
Overview: Shallower overall height with tighter knuckle options when vessel height is constrained.
ASME Hemispherical Tank Heads
Diameters:
30″, 37″, 41″
Overview: Uniform stress distribution for high-pressure service.
Diameters:
30″, 37″, 41″
Overview: Uniform stress distribution for high-pressure service.
ASME Segmented Hemispherical Tank Heads
Outside Diameter: 24″–300″
Nominal Thickness: 10 GA–1.5″
Overview: Large-diameter hemispherical designs fabricated from welded segments to meet code and size requirements.
standard non-code tank heads
Designed for atmospheric and low-pressure service, our non-code tank heads offer the same forming precision and material quality as our ASME products—without the added code requirements. They’re a cost-effective, reliable choice for storage tanks and general-purpose applications.
Non-Code Flanged & Dished Tank Head
Outside Diameter: 6″–268″
Nominal Thickness: 14 GA–1.5″
Overview: Cost-effective choice for atmospheric or low-pressure service with the same forming precision as our code products.
Flanged-Only Tank Head
Outside Diameter: 12″–240″
Nominal Thickness: 14 GA–1.5″
Overview: Simplified geometry and fast lead times for general-purpose tanks.
Dished-Only Tank Head
Outside Diameter: 6″–282″
Nominal Thickness: 10 GA–1.5″
Overview: Crown-only profile for specialized assemblies or field modifications.
Flanged & Flued Tank Heads
Large Diameter (Max): 96″
Small Diameter (Max): 48″
Nominal Thickness: 10 GA–1.25″
Overview: Flued transitions for shell connections where flow or structural needs call for a necked opening.
