Bent pipes for fluid technology from hansa‑flex

HANSA‑FLEX designs and manufactures bent pipes and special fittings with the highest precision, using state-of-the-art technologies and in first class quality.

The high-tech pipe bending cell operatives are completely familiar with all the necessary manufacturing steps from feeding in the cut-to-length pipe to the correct storage of the bent pipe.

The experts in the HANSA‑FLEX pipe bending centre have the necessary skills and knowledge of pipe bending and fluid technology to master the most complex challenges. They work closely with the specialists from the HANSA‑FLEX branches. You can expect the best possible advice and an optimum path from conception to manufacture. On request, HANSA‑FLEX is happy to manufacture ready-to-install pipe sets and deliver them Just-In-Time directly to the customer’s installation site, so that the entire process after pipe bending runs smoothly.

The bending experts at HANSA‑FLEX determine all the data required for the bent pipe from the computer simulation. If the simulation shows that the degree of ovalisation in the bend area exceeds the 10 % limit applied in hydraulics, then an internal mandrel is used during bending to prevent the pipe cross section from narrowing.

Reducing the ovalisation reduces turbulence in the pipe system and increases efficiency.

To meet the diverse requirements for pipe geometry needs many more than one type of machine. The extensive range of machines in the pipe bending centre allows HANSA‑FLEX to perform a wide variety of bending tasks and produce the highest quality results.

HANSA‑FLEX continually acquires new machines to ensure not only the highest precision but also maximum flexibility on the production floor. Around 20 further CNC machines augment a fully automated bending cell.

All enquiries for bent pipes are first subjected to a HANSA‑FLEX feasibility check. This simulation is done with visualisation software. The software considers all parameters such as bend length, stretching and springback. From these values, it calculates the precise sawn length of pipe that will result in a ready-to-install bent pipe after bending. A suitable CNC bending machine makes the bent pipe using the data from the simulation. The manufactured prototype is then checked using a measuring arm and compared to the master data. If all the dimensions agree, the feasibility check is passed under the HANSA‑FLEX technician gives the green light for production.

Individually manufactured pipelines and fittings are often required in fluid technology. HANSA‑FLEX set up a special manufacturing centre for special pipes and fittings at Dresden-Weixdorf specifically to satisfy this demand. All components, whether one-off or series production, are manufactured here with computer-controlled precision. Left and right pipe bending machines can master even complex pipe geometries. Machines equipped with a turret can make bend pipes to different radii in one working operation. This allows HANSA‑FLEX greater flexibility when making customised connections and shortens delivery times.
