HWT 250 MI / 315 MI
HÜRNER HWT 250 MI and HWT 315 MI for manufacturing PE, PE 100 RC, PP, and PVDF1) pipes, segmented bends, and fittings.
The design of the machines are such that pipes, segments O.D. 50 – 250 mm / 1½"– 8" and O.D. 90 – 315 mm / 3"– 12" with any SDR ratio up to SDR 11 can be processed.
The systems were developed under the machinery directive 2006/42/EC as amended, as far as applicable, and is set on a welded and bolted, totally heavy-duty support frame resistant to warping by design. Both the movable carriage of the system and the console carrying the heating element and the facing tool travel on precision-engineered, heavy load-bearing shafts and trapeze-shaped guides constructed with smoothly travelling runner blocks.
Inserting the PTFE-coated heating element and the facing tool manually is as convenient as it is effortless. The swiveling master clamps on both sides can be rotated by up to 2 x 15 deg. (∢30 deg.) and also feature horizontal adjustability, to allow for compensating any misalignments.
Heating element temperature control and facing tool operation are managed on the front panel.
For storing and transporting the HÜRNER HWT 250 MI and 315 MI, a high‑spec wooden transport box specifically designed for the welding system with drawerlike inlays for reductions and accessories is included.
