See the Welping A Max Series hydraulic butt fusion machine in a workshop demonstration featuring HDPE pipe clamping, carriage movement, dual-knob pressure adjustment, and remote operation. Explore its reinforced frame and practical operating features.

Welping HDPE stub end holders feature adjustable clamping positions and hand knobs for securing stub ends during butt fusion welding. Models from 160 to 2250 are available, with custom sizes and mounting configurations to suit specific requirements.

This brand-new, fully automatic stainless steel pipe roll grooving machine (covering sizes from 2 to 12 inches) delivers precise grooving across the full range of stainless steel pipe specifications. It overcomes the drawbacks associated with traditional processing methods—such as pipe deformation, poor precision, limited compatibility, and low manual efficiency—by offering stable performance and standardized forming quality. It is widely used in a variety of engineering projects.

Welping’s new Tracker 7 and Tracker 10 data loggers support HDPE butt fusion with welding parameter calculation, step-by-step guidance, and real-time pressure and temperature monitoring. They save joint records for review and traceability, with on-site printing and USB export for easier record management.

WELPING’s new HydraFlex™ HPU hydraulic station for butt fusion welder. With a unique dual-knob pressure control design different from conventional hydraulic units, it allows operators to pre-set pressure once and quickly switch pressure values for facing, bead-up, heat soak, fusion and cooling phases, without repeated pressure resetting. Matched with wired remote control, it brings simpler operation, stable pressure output and higher efficiency for HDPE/PE pipe site welding projects.

Welping will exhibit at the 140th Canton Fair in Guangzhou from October 15–19, 2026, showcasing newly updated 2026–2027 product catalogues along with the new A Max butt fusion series, Tracker wired and wireless data loggers, Gruv-Max and Gruv-One roll groovers, and the upgraded AG-8Z.

Customers recently visited the WELPING factory to explore our production facilities, pipe fusion equipment, and manufacturing process. The visit included an on-site factory tour, product discussions, and face-to-face communication about equipment applications and future cooperation.

*Simple & robust** — relies on a heavy line-frequency copper transformer, with fewer electronic components to fail.
*Bulky & heavy** — typically 30 kg or more, difficult to move around job sites.
*Basic control** — output is usually regulated by taps or timers, with limited precision.
*Lower efficiency** — higher no-load losses and greater energy consumption.
*Best for** — basic, low-volume PE pipe joining where portability and precision are not critical.

Meet Gruv-One RG-4M, the ultra-compact manual roll groover built for tight spaces. With a 1 1/4"–6" grooving range, a lightweight 10 kg design, and just 90 mm of required clearance, it can go where many conventional groovers simply can’t. Designed for pipes already installed in the air, Gruv-One makes In-The-Air grooving easier, lighter, and a lot less frustrating.
