TUBE BENDING
Your specialist in bending work of complex types of bendable materials
Bending
Your specialist in bending complex shapes of bendable materials. Tebunus is located in Ursem in North Holland and has proven its qualities in the field of bending technology that the name has become known at home and abroad.
We bow coldly. This keeps the consistency of the material intact. We can process carbon and stainless (stainless steel), (ground/polished) steels, copper, aluminum and exotic types. Tebunus Tube Bending bends the most difficult shapes with the greatest accuracy in tubes from Ø2.5 – Ø114.3 mm and in aluminum up to and including Ø168.3 mm. We continuously invest in our own machinery and tool shop. Our enormous capacity to bend to all sizes imaginable can reduce complicated welding tasks in complex projects. In addition to bending, we also assist you in: sawing, deburring, applying welding edges, machining techniques, hydrostatic testing and other quality controls.
Cutting
Tebunus Tube Bending meets the latest standards when it comes to the cutting/sawing to the required length. With our advanced, full automatic saws, we can cut lengths up to 10,000 mm with a diameter of 10 to 88.9 mm. The deburring process is integrated in the cutting. This decreases the cutting time significantly, which saves time and costs.
Deburring
We can deburr products fully automatically and manually. Sharp, upright edge created on a workpiece by cold metal working, such as punching, punching or sawing, we remove. The elimination is called ‘deburring’. The method of deburring is determined by the shape of the workpiece and the nature of the material.
Remarking
We are authorized to re-mark materials at our own location (re-stamping or re-marking). With the re-marking of materials with a 3.1 or 3.2 certificate (EN 10204: 2004) we offer you the optimal identification. We can trace individual products from which materials they consist. We also systematically provide and manage associated documentation and certificates with over-stamping. A brand is a set of numbers and letters or images on a product or material that indicates where it comes from. If this mark has disappeared or faded, we can re-apply it so that traceability is guaranteed.
Our Certificate.
Machining
Within Tebunus we have a separately equipped machining department. Here we manufacture our bending tools in-house. We have an answer to almost all production technical questions. The bending tools are made on one of the two CNC milling machines and on the CNC lathe.
Welding edges
Tebunus Tube Bending carries out bevel cutting according to standard ASME B16.25 (Weld Preparation).
Pressure / hydrostatic testing
With an extruder unit we bring a liquid under high pressure in the tube. If a product shows leakage, we see it as droplet or fountain formation.
dye penetrant
We have certified employees for dye penetrant research. The penetrant is applied to the cleaned surface. Penetrant research is a non-destructive test, usually used to detect cracks. It can also be used when magnetic research is too difficult to apply. Method:
- Cleaning the surface of dirt, paint, oil, grease and rust. This can be mechanical (sanding) and chemical;
- Apply penetrant. The penetrant needs 10 to 30 minutes to penetrate the cracks.
- Too much to remove Penetrant;
- Applying a developer that pulls out the Penetrant that had penetrated into the cracks.
- Colored spots indicate the position and shape of the cracks
- Inspection of the test surface. Immediately after applying the developer, and a second time after 15 minutes;
- Cleaning the sample.
Annealing
We can easily remove stresses or irregularities in a piece of metal by means of annealing in an oven. The metal is heated in a special gas oven. Due to the high temperature, the metal becomes less brittle and can be processed better.
Degreasing/cleaning
Tebunus Tube Bending removes contaminants consisting of oils, grease and loose dirt of products and materials. Amongst others we have a special industrial washing machine available.
Our customers and partners
We only supply products that meet all requirements and customer expectations. Our rejection rate is extremely low. We always test our end products.
