Welding machines
This line includes the civil and industrial applications of the Hürner Italia S.r.l. program and is based on the following lines:
- Butt welding machine and accessories;
- Electrofusion welding and induction machine and accessories;
- Polyfusion socket welding machine and accessories;
- Hot-air welding machine and miscellaneous accessories for pipe laying;
- Sheet and segmented fittings welding machine;
Hürner Italia S.r.l.’s on-site welding machinery, based on the head-to-head procedure they are present in three different fields of application:
- for pressure lines;
- for high-purity lines with and without a welding bead;
- for drainage systems;
The materials that can be joined using these procedures are PE, PP, PVDF, ECTFE, PFA, and FEP.
In workshops, welders are normally automatic machines for segmented components starting from OD 315 mm up to OD 1600 mm. Larger diameters can be achieved and currently go up to OD 3000 mm. Welded plates machine of varying widths ranging from 2000 mm up to 4000 mm available for joining sheet thicknesses up to 50 mm are less for ducts, but more for the construction of equipment’s.
Hürner Italia S.r.l. electrofusion welding machines are based on the reading of bar codes type interleaved 2 of 5 using scanners that execute joins up to OD 1200 mm for PE 100, up to OD 400 mm for PP and for PVDF they can reach OD 63 mm . The machines currently on the market for PE and PP are, unfortunately, not suitable for the electrofusion welding of PVDF, for which there is a specific machine.
The induction welding machine that welds the OD 50, 90, and 160 mm sleeves has been inserted for the dual pipes.
This induction welding technology is to be ringed in this case, applies to PE100-PE100 and PPR-PPR monolithic dual pipework .
With regard to coatings using the ANTICOR PE AD liner, a new welding technology has been developed that is based on the induction process in order to fix the liner to concrete walls. A washer with a built-in electrical coil is stuck to the wall using half a dowel, the liner is placed on the washer and by pressing the electrical source on the wall and the washer beneath, a joint is made within a few seconds without the need to drill through the coating at any point.
