Tank Heads Spinning OEM Overview


As your strategic Original Equipment Manufacturing (OEM) partner, HS Metal Spinning delivers high-performance Tank Heads Spinning OEM solutions designed for the rigorous demands of the storage and process industries. Tank ends—whether torispherical, semi-ellipsoidal, or hemispherical—are the foundational closures for horizontal and vertical vessels. We expertly form these monolithic components from materials including Stainless Steel (304/316) and Carbon Steel, guaranteeing perfect rotational symmetry, uniform wall thickness, and a seamless structure that eliminates high-stress weld seams and potential leak paths for liquid and gas containment.


Advantages of Our Tank Heads Spinning OEM Products


Partnering with an OEM specialist for spun tank ends provides critical technical and structural benefits over fabricated or multi-part alternatives:

Monolithic Structural Form

Spinning forms the tank head from a single blank, resulting in a jointless structure. By removing the vertical weld lines found in segmented heads, we provide a superior strength profile that is safer for high-volume storage and pressurized vessels.


Predictable Geometric Consistency

Our multi-axis CNC lathes ensure that the knuckle radius, crown radius, and straight flange meet exact blueprint constraints. This high geometric fidelity ensures a perfect fit-up to your tank shell, minimizing assembly downtime and welding issues.


Work-Hardened Durability

The high-force cold-forming process work-hardens the metal, increasing yield strength and resistance to mechanical impact. This ensure the head maintains its integrity throughout the lifespan of the tank, from transit to terminal operations.


Custom Tooling Efficiency

Spinning offers a faster, more flexible route for producing non-standard diameters and depths compared to the multi-million dollar die sets required for stamping, providing a highly cost-effective OEM stream for custom projects.


Our Tank Heads Spinning OEM Technological Process


Operating as a premier Tank Heads Spinning OEM requires massive industrial power paired with micron-level digital control:

1. Code & MTR Verification

We analyze material blanks to ensure certified ductility and source traceable materials specifically for industrial and pressurized service.


2. Hardened Tooling & Mandatory Radii

We utilize mandrels machined to match specific 2:1, F&D, or spherical geometries, providing the rigid foundation for precise forming.


3. Controlled High-Force CNC Spinning

The blank is drawn incrementally using digitally monitored tool paths on robust lathes, ensuring uniform wall thickness and perfect rotational balance.


4. Integrated Trimming & Fabricating Features

We perform in-house secondary operations, including coordinate trimming of the straight flange and beading if required for stiffening.


5. Rigorous Dimensional Validation

Every head undergoes visual and metrology verification (CMM/Laser) to confirm that mounting diameters and profile radii meet purchase order specifications within sub-millimeter tolerances.

FAQs about Tank Heads Spinning OEM


Can you provide a J-bevel or V-bevel for certified welding?

Yes. Our service includes applying the exact weld prep bevel your design requires, ensuring the head is ready for immediate fusion welding to the vessel shell.


What is the standard straight flange length you can spin?

Standard flanges range from 25 mm to 100 mm, but we can spin custom longer flanges during the initial forming process if your tank assembly requires extra joint distance.


Do you supply the mill test reports (MTR) with every order?

Yes. For all OEM tank head contracts, full mill traceability and dimensional verification reports are provided to ensure compliance with your internal quality control and customer audit requirements.
