As a dedicated Original Equipment Manufacturer (OEM), HS Metal Spinning supplies high-integrity OEM Stainless Steel Spun Tank Heads—the foundation of reliable pressure vessels and storage tanks. Tank heads (or vessel ends) must guarantee structural stability, resistance to internal pressure, and long-term corrosion resistance. We expertly form seamless, precise heads—including torispherical (dished), semi-ellipsoidal, and hemispherical designs—from certified stainless steel (304, 316). Our advanced CNC spinning process ensures uniform wall thickness and perfect geometry, providing a code-compliant, durable, and reliable solution for industrial and sanitary applications.
Partnering with us for your OEM Stainless Steel Spun Tank Heads provides assurance in structural performance and compliance.
Spinning forms the tank head from a single piece of stainless steel. This monolithic structure eliminates weld seams and heat-affected zones (HAZ) in the main body, significantly enhancing pressure rating reliability and longevity, essential for high-stress applications.
Our precision CNC process ensures a highly uniform wall thickness across the entire head, including the critical knuckle radius. This consistency is mandatory for calculating predictable stress distribution and achieving compliance with codes like ASME BPVC.
We utilize certified, traced stainless steel grades (e.g., 316L for corrosive media), ensuring maximum resistance to tank contents and external environments.
We deliver tank heads with precise edge preparation (beveling) on the straight flange, guaranteeing a perfect fit and high-quality, code-compliant weld joint to your vessel shell.
Manufacturing code-compliant tank heads requires a rigorous process emphasizing material control, precision forming, and critical documentation:
We confirm the necessary design code (e.g., ASME, PED) and verify the stainless steel grade (with mill certifications) and traceability of the material blank.
Heavy-duty, certified mandrels are fabricated. Our CNC programs precisely control the intense forming force and multi-pass path required to maintain wall thickness uniformity in the stainless steel.
The stainless steel blank is formed on our robust CNC lathes. This ensures perfect rotational symmetry and consistent wall thickness, which are non-negotiable for pressure vessel components.
We perform precise in-house secondary operations, including trimming the straight flange and applying the required bevel or weld preparation to the edge, readying the head for final vessel assembly.
Every finished head undergoes stringent dimensional inspection using advanced metrology. We provide full material traceability documentation and can perform Positive Material Identification (PMI) testing upon request to ensure final material integrity.
We commonly work with certified 304/304L and 316/316L stainless steel, offering material certifications (MTRs) and supporting your code requirements for these grades.
Yes. Our seamless spinning process and precise weld prep ensure the heads are manufactured to the highest quality standards, facilitating required NDT procedures, including UT and radiographic testing of the final weld joints.
Spinning requires custom tooling (mandrels) only, which is significantly less expensive and faster to fabricate than the custom die sets required for stamping, making spinning highly cost-effective for custom sizes and moderate production runs.
At HS Metal Spinning, we focus on providing specialized Original Equipment Manufacturing (OEM) solutions for Stainless Steel Spun Tank Heads. We are a technical partner that understands the stringency of the pressure vessel industry.
Our service includes expert guidance on selecting the optimal head profile (e.g., ASME F&D, 2:1 Elliptical) and grade of stainless steel. We provide comprehensive DFM (Design for Manufacture) analysis, managing material traceability and ensuring all key parameters—such as crown radius and straight flange depth—meet your exact blueprint specifications.
Spanning over 10,000 m² (over 107,000 sq ft), is designed specifically for large-scale, high-volume OEM production. This robust infrastructure ensures that HS Metal Spinning can deliver rapid turnaround and scalable manufacturing for projects ranging from low-volume prototypes to high-volume production runs, guaranteeing your supply chain remains uninterrupted. Our clean, well-lit, and highly organized environment is a testament to our commitment to a professional manufacturing process. Every piece of equipment is meticulously maintained and regularly calibrated to ensure the highest level of precision.
Our facility is equipped with a comprehensive suite of advanced machinery that represents a significant investment in technology and efficiency. These machines allow us to take on complex projects with confidence and precision. The equipment includes:
The core of our operations, these machines are at the forefront of metal forming technology. With a variety of different models and sizes, our machines can handle a wide range of part diameters and thicknesses. This versatility allows us to produce everything from small, intricate components for electronics to large-scale parts for aerospace and industrial applications. Our machines are capable of executing complex forming sequences with repeatable accuracy, minimizing human error and maximizing efficiency.
These machines provide us with integrated fabrication solutions. We can swiftly and precisely create multiple holes, slots, or other shapes in your spun parts, eliminating the need for a separate, time-consuming process. This capability is vital for components that require specific mounting points or ventilation features.
This further enhances our in-house capabilities, enabling us to perform precise cuts and create intricate patterns on pre-spun components. The laser cutter provides exceptional accuracy and clean edges, which is crucial for high-quality finished products. HS Metal Spinning also has a full range of essential CNC machines, ensuring we are a turnkey manufacturing solution for all your OEM needs.
As a leading OEM partner, HS Metal Spinning is more than just a manufacturer; we are a dedicated partner committed to precision and reliability.
