HWT 160 SW–E
This professional socket welder for setting branch-off fittings into the pipe wall is designed for all-purpose welding applications in PP and PEHD pipeline grids, to make branch‑offs of O.D. 20 - 90 mm from straight pipelines of O.D. 40 - 160 mm. It is the ideal choice for making lines branching off from fittings set into the pipeline sidewall in tight corners, but also for workshop applications meant for the serial manufacture by a reliable process of distribution/manifold lines, e. g., in geothermal systems.
The standard delivery includes the all-purpose pipe aligners for straight pipelines sized O.D. 40 - 160 mm, a bracket compatible with various cordless drills/screwdrivers Ø 43 mm driving the drilling head, and clamps for branch-offs in the saddle position sized up to O.D. 63 mm allowing precision alignment of cylindrical and octagonal fittings.
With the HÜRNER quick mounting system, the clamps can be replaced easy as ABC. The chassis/carriage, without the RH and LH pipe‑aligning clamps, can be removed from its steel frame by simply loosening 4 mounting screws and can then be used in areas that are hard to reach or overhead.
Both the operation of the clamps for the straight pipe and the saddle fitting and the movement of the carriage for the latter are implemented as using ergonomically designed handwheels. Additionally, the motion handwheel can be removed easily, to move the clamping chassis/carriage with a common power tool (cordless drill/screwdriver) as its drive.
A special mention deserve the heating element seat next to the chassis for clamping the saddle fitting, on which to place the heating element, and the two freely adjustable depth setpoints. The easy insertion and safe and swift removal of the heating element, including centering and an auto‑detaching step in the change‑over stage, bring a use as convenient as to be considered unique.
The insertion depth setpoints provide, on the one hand, consistent fusion depth and welding position and, on the other, shorter length of movements, thus faster change-over.
