For years, we have been a proud part of the tubing industry, using our talents and knowledge to provide clients with modified tubes that meet their every requirement. Specialising in tube manipulation, our team has assisted those who belong to both the industrial and domestic sectors, producing tubes for railings, public transport fittings, furniture, and much more. Flexible in our approach and capable of working with a wide variety of materials, you can count on us to get the job done.

One of the most crucial elements in tube adjustment is the bend radius. Whenever people refer to this, they are speaking about this appraised to the tube’s centre line. Everyone has their own draw bend radius utensils, but the most regularly occurring shall likely be in line with the rule of thumb, which is that the benchmark draw bend is 2 x D.

For those who are unfamiliar with this calculation, it means that if your tube’s OD (outside diameter) is 20mm, then the radius you’ll want to go with is 40mm, if this is possible. You can have denser radii however, even ones that reach half x D. It should be noted that anything under 2 x D will probably need expensive tools, not to mention mandrel bending.

If you look at the other edge of the scale you shall discover that the total draw bend radius isn’t determined by the tube’s overall performance. Instead, it’s all down to the instruments you can fit into your bending apparatus. Depending on your diameter, the amount could be gigantic, but as we said earlier, deviating from the rule of thumb brings with it inflated tool costs.

At Multiform Tubes, customers always expect the absolute finest in tube manipulation. Luckily this is precisely what we present to them each and every time. With the aid of our advanced technology, we can generate accurate and coherent results whenever we’re called upon to perform manipulation work.
