This article shows the RG-4X Pro grooving steel pipes under real working conditions. It explains how the machine’s integrated frame, upgraded rollers, reinforced pipe stand, and strengthened positioning wheel work together to improve stability, reduce vibration, and help produce consistent groove quality.

A customer visited our factory to review production conditions and butt fusion welding machines. The visit included workshop inspection, equipment checking, and discussions on practical applications, providing a more direct understanding beyond documents and photos.

Welping produces Butt Fusion Welding Machines with dedicated machining and assembly lines.

A test on 20Mn 16-inch steel pipe showed that while standard machines could complete grooving, efficiency dropped under load. The AG-4X significantly improved speed and stability, reducing processing time to about 2 minutes per joint. The case highlights the importance of matching equipment to high-strength materials and demanding working conditions.

At the 139th Canton Fair, a PE pipe scraper from Welping attracted strong interest and was purchased directly by a customer on-site. Available in two models (PPS24 and PPS32), the tool features a clamp-on structure, simple operation, and smooth performance. It serves as an efficient surface preparation tool for PE pipe electrofusion welding.

Both drive systems are capable of completing the facing process.
However, for long-term use and higher load applications, gear-driven facers provide more stable and predictable results, making them more suitable for large-diameter butt fusion work.

Welping is exhibiting at the 138th Canton Fair, with its booth located on the ground floor. A range of pipe equipment is on display, including butt fusion machines, electrofusion machines, and roll grooving systems. New products are also presented, offering visitors a closer look at recent developments in pipe welding and grooving solutions.

Pipe support is often overlooked in grooved piping systems, yet it plays a critical role in long-term performance. While cutting and grooving ensure proper installation, improper support can lead to sagging, uneven stress, and reduced system stability over time. Reliable pipe hangers help maintain alignment, distribute load, and prevent issues that only appear during long-term operation.

FX series large-diameter butt fusion machines use an anti-slip pad system to improve pipe stability during welding. By increasing contact area and enabling adjustable positioning, the pads help reduce slippage and adapt to non-standard pipes. With multi-point contact (e.g., 96 pads on FX1000), the system ensures more even load distribution, supporting stable and consistent performance in real jobsite conditions.

The FX Gen 2 HPU introduces a redesigned hydraulic system for butt fusion machines, focusing on process-based control, operator positioning, and structural integration. Instead of incremental changes, the system separates control logic for different stages and allows operation closer to the pipe. The result is a more direct, stable, and consistent workflow in real applications.

The Gruvmaster upgraded pipe cutting blade is designed to deliver stable and long-lasting cutting performance. Compared with conventional blades, it maintains sharpness over extended use, supporting up to 20 continuous cuts without noticeable dulling. Suitable for steel and galvanized pipes, it helps improve cutting consistency, reduce downtime, and lower overall tooling costs in both workshop and job-site applications.

This workshop session shows the FX500 butt fusion machine in real operation. From pipe clamping and alignment to handling the facer and heating plate with a lifting crane, the process reflects actual working conditions. By participating directly, the team gains practical understanding while documenting the workflow for a clearer and more realistic demonstration.

The PTC140 pipe cutter is designed for practical, on-site use where cutting is frequent and efficiency matters. Instead of focusing on complexity, it delivers a stable structure, clear operation, and smooth workflow. With an intuitive layout and consistent cutting rhythm, it helps operators work faster and more reliably in real construction environments.

WELPING introduces a new 355 butt fusion clamp design with die-cast structure, improved consistency, dual 355mm/14” compatibility, and enhanced mobility.

This article explains the role of a data logger in PE pipe butt fusion welding. By automatically recording key parameters such as temperature, pressure, heating time, and cooling time, the data logger helps create traceable welding records. Compatible with A, FX, and A Pro series machines, it supports ISO and DVS standards and improves quality control in pipeline construction projects.

Grooving large steel pipes from 8" to 24" introduces challenges that go beyond simple machine power. Structural rigidity, hydraulic stability, and controlled roller pressure play a critical role in achieving consistent groove quality. This article explains the key factors affecting large-diameter grooving and discusses how machines like the RG-4X are designed to address these operational demands.

WELPING’s upgraded FX500 Butt Fusion Welding Machine now features an integrated crane hoist for simpler, safer operation. Our sales team recently completed hands-on workshop training, directly operating the machine to master its design and performance.

This article explains why internal gear drive matters in a pipe fusion facer used for butt fusion welding. Compared with common chain-driven structures, a gear-driven system provides more stable transmission, smoother rotation, and easier maintenance. By driving the cutter plates evenly, it allows both pipe ends to be faced simultaneously, helping ensure consistent pipe preparation before welding.
