PRODUCT NEWS

Nearly 200 RG-1M and RG-2M manual roll groovers have been assembled and are ready for shipment to the U.S. Each unit is tested for quality and designed for both manual and power-driven use, reflecting Gruvmaster’s reliable and versatile roll grooving solutions.

Customer Story from Brazil: A nighttime HDPE pipe fusion project using the Welping WP500A. The machine ran smoothly and reliably, helping the crew complete their work safely and efficiently.

Welping WP Q Series fully automatic hydraulic butt fusion machines deliver high-precision, data-recorded welding for HDPE gas and water pipelines. FX, A Pro, A, and B Series semi-automatic machines offer reliable manual control, cost efficiency, and flexibility — providing complete butt fusion welding solutions from intelligent automation to professional field applications.

The Gruvmaster RG-1 Series offers four compact hydraulic roll grooving machines — RG-1A, RG-1B, RG-1C, and RG-1X — covering 1"–8" pipe sizes. Each model combines precision, durability, and smart design for different job requirements. The new RG-1B, featuring a lift-assist chassis and integrated toolbox, highlights Gruvmaster’s innovation in portable and efficient pipe grooving solutions.

Harsh weather can challenge any fusion machine. Mud, rain, cold, and heat all impact performance if left unprotected. This guide explains how to safeguard your FX and WP Series butt fusion machines through proper setup, temperature control, and maintenance. With the right precautions, you’ll ensure lasting reliability, stable pressure, and strong weld quality in any environment.

Gruvmaster introduces its new TiAlN (Titanium Aluminum Nitride)-coated roll sets, offering rust-free, oil-free, and 2–3× higher wear resistance. Now standard on the flagship RG-8X, they deliver smoother, more precise, and longer-lasting professional grooving performance.

The RG-8X flagship hydraulic roll grooving machine is built for heavy-duty pipe work. Featuring a leak-free system, high-speed efficiency, and precision anti-flare design, it meets international standards while ensuring safety and ease of use.

In a Libya water pipeline project, the Welping WP1600 butt fusion machine efficiently welded large-diameter HDPE pipes, delivering strong joints and boosting construction efficiency with easy operation.

The foot pedal, also called a safety switch, is a key feature in roll grooving machines. It enables emergency stop, hands-free operation, better efficiency, less fatigue, and precise control. Gruvmaster equips multiple models with this feature for safer, more reliable work.

This successful practice reinforces our belief that by relying on reliable equipment like the WP315A PRO and WELPING's standardized environment—and, more importantly, through every operator's strict adherence to procedures—we can consistently deliver high-quality welding results. We are committed to applying the lessons from this experience to every job site.

In butt fusion welding, single-size clamp inserts are crucial. They are specialized fittings inside machine clamps that secure pipes of specific diameters, ensuring pipe centering and stability during welding. With advantages like accurate alignment, time-saving, quality improvement and durability, Welping also offers high-quality ones matching its fusion welding machines.

Gruvmaster’s top roll grooving machines—RG-5X, RG-2M, and RG-1X—deliver reliable solutions for contractors. From powerful hydraulic roll groovers to portable manual pipe roll groovers, they ensure efficiency, precision, and durability in every piping project.

Groove depth is key to pipe joint reliability. Too shallow or too deep weakens the system. Gruvmaster roll grooving machines with depth lock knobs ensure precise grooves, meeting AWWA C606, FM, and UL standards for long-term safety.

Urban gas pipelines require strict pressure testing, typically 0.6 MPa for 48 hours. HDPE pipes offer excellent strength, sealing, and corrosion resistance, ensuring long-term safety. Welping provides reliable welding equipment to support secure and durable urban infrastructure.
