Our pipe products

Reliability is our strength
Nothing is more annoying than missing goods. After all, your pipeline is only complete when all the individual parts have arrived. That's why we store all pipe fittings, pipe elbows and flanges as a one-stop shop for quick complete shipping. This eliminates unnecessary waiting times and delays due to non-existent steel fittings or missing steel flanges.

Quickest supply
That's why we deliver all pipe products in the most common materials S235, P235GH, P265GH and P355NH directly from our warehouse in northern Germany via daily general cargo transport and parcel shipping. If you wish, you can also collect the goods from us yourself.

What do I have to do to receive the material certificates I ordered?
The material certificates are included by default in our presets. They will be sent to you by email as soon as the products are shipped and will therefore be with you before you receive the goods. If you do not need certificates, you can easily remove them from your shopping cart.

Can't my colleagues from the workshop make the deliveries themselves?
Yes, definitely! At protubo.biz, every requestor can create their own account and release the deliveries. But we also send orders directly to other branches, to the workshop with its own delivery address or to the construction site without any loss of time.

I didn't find the product in the steel grade I wanted, what now?
You can simply call us on +49 (0) 4202 9555 50 or send an inquiry by email to team@protubo.biz. If that doesn't fit right now, just check back later. We regularly supplement our product selection and material composition. New pipe fittings and steel flanges are specially marked in the selection list so that you can immediately recognize the innovation.

My project specifies a steel material that I cannot find on protubo.biz.
Just get to the bottom of the problem! Common alternatives can often be used. The most common steel materials for pipe bends, fittings and flanges are offered at protubo.biz. The material properties are shown on the data sheets. Here you will also find the data sheets for steel types with increased requirement profiles such as P265GH and P355NH in the detailed view of each item.

I only have a material number, but not the material name.
