Frequently Asked Questions

Metal spinning also known as spin forming is a cost-effective process used to form conical, hemispherical, and cylindrical shapes. A starting blank (flat disk) is spun over a tool in a series of sweeps by a forming roller, the metal is progressively shaped onto the tooling to produce the desired shape, producing the finished part.

In general, Metal spinning offers flexibility with low tooling costs and is widely used for either low or high-volume production. Depending on the application, spinning can offer major benefits which often makes it an ideal choice.

Tanfield Metal spinners will quote for work up to a radius of 2.4 meters 10mm thick. We also partner with an international spinning company for anything above Tanfield current capabilities.

Our technical engineering department will supply a drawing on your request for a quote, at no additional cost, which can be signed off before order.

All parts manufactured from Tanfield will have full traceability, all materials that require certification will be automatically sent to our customers on completion of the order.

The following materials can all be spun. If your project requires a different metal, we can work with many more specialist materials, however these will typically require heat (annealing) to meet your specifications.

Aluminium
Brass
Carbon Steel
Copper
Corten
Duplex
Hastelloy Alloys
Inconel
Mu-metal
Nimonic
Nirosta
Silver
Stainless Steel
Titanium
Zintec

Tanfield prides itself on maintaining a 3–4-week lead time where possible, if tooling is required this can extend the lead times.

Tanfield’s standard tooling stock is the largest in the country and we invest in it on a yearly basis.

If your project requires new tooling Tanfield will look at the most cost-effective way to service our customer’s needs.

Delivery is always a next day service; this can be upgraded to before 12 at an extra cost.

At Tanfield Metal Spinners, we use our expertise in metal forming to create a variety of metal spun parts. This includes dished ends, pressure vessels, spun metal cones, tank heads, and more. We can quote work up to a radius of 2.4 meters and a thickness of 10mm for spun parts.  

Tanfield’s metal spun parts can have applications in products with drastically different uses, across many sectors. As a result, there is a large scope as to the businesses that can make use of Tanfield’s metal spinning services. All parts spun by Tanfield Metal Spinners have full traceability too.

Bespoke metal spinning is the custom manufacturing of metal parts by spinning sheet metal into specific shapes tailored to client needs. We adapt to meet your project’s exact specifications. When you work with our team, you have access to metal spinning services that are entirely unique to your organisation and purpose. We use our expertise to consider which materials and processes will produce the best results for your project. 

Dished ends are the end caps welded to the main body of a pressure vessel, providing pressure containment, strength, and stability. The curved shape distributes pressure evenly, reducing stress concentrations and preventing deformation. Dished ends are effective in increasing the internal volume of a pressure vessel, allowing more space for liquids, gases, or any other materials.

They can be created in different ways depending on the type of end that is needed for the project and also will need the properties that make it suitable for its application once completed. Types such as flat flanged ends, ellipsoidal, hemispherical, and torispherical dished ends offer varying levels of strength and fabrication ease, making them essential for durable and efficient pressure systems.  

A pressure vessel is a secure container that is designed to hold a range of vapours, liquids, and gases. Pressure vessels can come in different shapes and sizes depending on their specific applications. A typical model of a pressure vessel is a long cylinder combined with two heads.

Pressure vessel parts may be used for heat exchangers, reactors, flash drums, distillation towers, and separators and are expertly spun for the safety, chemical, petrochemical and food production sectors.
