The FX series hydraulic unit offers two pressure gauge options: a digital gauge for clear numerical readings and a mechanical pointer gauge that remains readable without power. This flexible configuration allows reliable pressure monitoring under different job-site conditions, ensuring stable pressure control for butt fusion welding operations.

Recently, our customized 1600mm butt fusion welding machine, tailored to the specific needs of an overseas client, has successfully rolled off the production line and is ready for delivery. This large-scale welding equipment integrates advanced data recording function and emergency stop system, perfectly balancing construction efficiency and operational safety, which has been highly recognized by the client during the pre-delivery inspection.

Welping’s gear-driven facer tools provide stable torque, consistent cutting, and long-term reliability in butt fusion welding. By replacing chain-driven systems with precision gears and a reinforced facer plate, Welping reduces vibration, minimizes maintenance, and improves pipe end flatness and weld quality.

These photos show roll grooving machines at the final assembly stage inside the Gruvmaster factory. Each machine is assembled by hand, with technicians performing alignment, pressure adjustment, and inspection to ensure consistent performance. Standardized assembly procedures help maintain stable quality across batch production before every machine is shipped.

The updated H402 Pipe Chain Vise is an upgraded version of our classic model, built with heavier-duty materials and a smooth, dense body produced through a RCS casting process. A newly added chain wear plate extends tool life, and makes clamping safer and more reliable - especially in tough jobsite conditions. With a wide working range from 1/8" to 6", it securely holds galvanized steel, stainless steel, copper, and aluminum pipes, delivering strong grip, smooth operation, and reliability.

Welping's 1200-1600mm HDPE Pipe Butt Fusion Welding Machine delivered outstanding performance in an Egyptian construction project, winning high recognition for its quality and stability, with the client praising Welping as "truly one of the best companies in China."

This article presents a photo update of the FX800 butt fusion machine from the FusingX series. Designed for 450–800 mm pipe diameters, FX800 is positioned for large-diameter applications. The update highlights the machine’s complete configuration and visible design details, with further technical topics to be covered in follow-up articles.

The FX800 butt fusion machine is designed for large-scale pipeline welding projects involving heavy loads and complex site conditions. Supporting pipe diameters from 450 to 800 mm, it features a dedicated hydraulic unit, safety-focused structural details, and clear operating logic. The FX800 provides stable, controlled, and reliable performance for systematic large-diameter welding applications.

This article explains the differences between plated rollers and stainless steel rollers used on Gruvmaster roll grooving machines. It focuses on thin-wall steel and stainless steel pipe applications, addressing deformation control, durability, and cost considerations. By matching roller selection to pipe wall thickness and operating conditions, users can achieve more consistent groove quality and stable roll grooving performance.

Welping Machinery successfully delivered one set of a butt fusion welding machine to a customer in Egypt.

This article records a factory photo session of the FX1000 butt fusion machine conducted on December 30, 2025. The FX1000 follows the same design and material system as other FX series models, with differences mainly in overall size. The photos highlight structural details such as the single-piece side frame, clamp design, and adjustable anti-slip pads.

This article looks at the evolution of the FusingX hydraulic unit, comparing the first- and second-generation designs and explaining how the latest version developed through long-term job-site use.Based on continuous field feedback, the second-generation unit introduces improvements in mobility, protection, operating flexibility, and overall usability, making it more suitable for HDPE butt fusion welding and extended on-site operation.

This article outlines the structural updates of the Gruvmaster RG-4X Pro compared with the RG-4X. The changes focus on practical improvements, including an integrated storage frame, a larger grooving assembly, reinforced pipe support, and upgraded positioning rollers. These refinements enhance stability, durability, and control during long-term roll grooving operations without altering the machine’s fundamental working principle.

This article documents the current hydraulic system configuration of the CM-20 pipe cutting machine. Based on a new set of on-site photos, it shows the transition from an integrated hydraulic design to a split structure with separate pump and cylinder. The update reflects structural considerations and real working conditions across the product line.

The FX450 butt fusion welding machine is designed for HDPE pipe welding in the 180–450 mm range, commonly used in municipal and general pipeline projects. It combines a stable welded frame, enclosed hydraulic unit, controlled heating, and a gear-driven facer to support reliable, repeatable welding during long and continuous on-site construction work.
