Request a Brochure

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 - 63 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.

HWT 160 CS

HÜRNER's HWT 160 CS servo-operated workshop system is the end-to-end transformation of worksite technology into workshop systems. The system has been developed in compliance with the so-called machinery directive 2006/42/EC as amended and allow making pipes, segmented bends and fittings in workable dimensions from O.D. 32 (20) through 160 mm | 1" (½") - 6". The welding system is set on a welded or a screwed-fast, heavy-duty, no-warp support frame and the bearings on which move both the horizontally traveling carriage and the heating element and facing tool assembly, are designed as precision-engineered and heavy load-bearing trapeze-shaped guides with precision-matched runner blocks. It goes without saying that all parameters that are critical for a high-quality and reproducible welded joint are monitored throughout the process and saved to the memory of the system, which can hold up to 10,000 reports. Furthermore, all CNC systems are equipped with a USB interface to enable downloading the welding reports in the PDF format to a USB stick or sending them to the management database in the HÜRNER DataWork Professional format. It is also possible to label a joint immediately for its quality by printing on plastic foil an indelible label tag with the available tag printer that will identify the fitting.

The machine is used to socket-weld PP, PVDF, PE pipes and fittings of O.D. 20 - 125 mm. Diamond-shaped clamps allow effortless positioning and securing of the fittings and pipes of all sizes. A specially designed fastening system is at the heart of the easy changing of the clamps depending on the job at hand.

The HWT 125 SW 2.0 features a unique reference setpoint pushbutton that enables convenient and professional adjustment of the component butt position. It goes without saying that fusion depth selectors and the corresponding spigots and sockets are available for common component types (DVS type A, DVS type B, ASTM in inches)

The system ships in a rugged, wooden transport and set‑up box (optional).

HÜRNER WhiteLine WeldControl 2.0

The handling of a WeldControl machine is simply unique and it enables an approach to welding no other system is able to offer. Either the operator makes use of the assistance of the interactively responding hydraulic and control unit. Or the manual mode is selected to make the joint “by hand”. In the WeldControl mode the system walks the operator through the process after the pipe parameters were entered or confirmed. This includes monitoring the operator’s inputs and recording the entire process. WeldControl machines do not only provide presets, though; they facilitate the work, e. g., by reducing the pressure automatically when the automode was enabled. Welding reports have all data required by ISO traceability. In the Manual mode the display screen works as a digital gauge. It displays the welding pressures and heating element temperatures and is a one-stop provider of all data. Industry version: Optionally, the machine chassis (250, 315, 355, 500, 630) are also available in an industry set-up with a modified 3^rd clamp for clamping fittings with a short connecting stub.*⁾ *⁾Retrofit kit for converting existing systems to industry version available upon request!

HÜRNER WhiteLine SPG 2.0

HÜRNER’s welding data logger SPG 2.0 is made for easy and safe welding process control and report logging pursuant to the ISO 12176 standard.

The report generation system is specifically matched to HÜRNER butt-welding machines of the Manual Hydraulic series, but can of course be used with other systems effortlessly. The SPG 2.0 control software ships ex works with configurations for many third-party systems already installed. Therefore, the logger constitutes an upgrade for manually operated welding machines to achieve ISO-compliant recording, error handling, and welding process control. At every step in the welding process, the SPG 2.0 indicates the nominal and the actual values of the welding pressures and times, to walk the welder operating the hydraulic unit easily and correctly through the process. The unit thereby achieves the optimum welding process, in line with nationally applicable standards, as affecting both heating element temperatures and welding pressures and times.

Filter Units with Fan

This filter with fan provides positive extraction and monitoring of chemical storage cabinets, in the form of almost 100% decontamination of the extracted air by molecular adsorption filtering of harmful solvent vapors (hydrocarbons). The filter operation means optimum protection for the user. As a consequence, no additional air extraction outlet is needed, which, in turn, allows the filter unit to be operated immediately next to, or on top of, the storage cabinet. The decontaminated air is released into the ambient air, thereby not consuming any heated or air-conditioned air from the room. A sensor monitors the extraction airflow and triggers a visual and audible alarm when no airflow above the set threshold is detected. The enclosure is made of silver pearl glimmer, powder-coated sheet steel. As an air extraction system, it as of today complies with “green lab” requirements, while offering you full flexibility of position. The multi-stage, grounded filtering system offers dual safety, being composed of: Activated carbon filter with twice as much activated carbon — for up to 100% decontamination Additionally a DIN EN 779-compliant particulate filter The filter alert appliance can be set at the differential pressure meter/switch. The filter elements themselves and the filter enclosure lid are monitored by ATEX-compliant micro-switches. The three-month check and replace interval of the activated carbon filter is verified by a check report the user has to confirm which is paired to a scheduler. The product ships ready for plug-in.
