During butt fusion welding of large-diameter HDPE pipes, clamping stability directly affects welding quality.
In real working conditions, the larger the pipe diameter—and the lower the ambient temperature—the greater the risk of pipe slippage during positioning and alignment.
To address this issue, FusingX developed an anti-slip pad block design.
This design is currently applied to large FX series butt fusion machines, including models FX800 and above.
With greater contact area, friction is enhanced. As a result, pipes are less likely to slip during movement and alignment, leading to more stable operation.
This improvement is especially noticeable in low-temperature environments, where HDPE pipes tend to become stiffer.
The anti-slip pad blocks are designed to allow fine adjustment.
When small deviations in pipe diameter are present, the pad blocks can be repositioned to better match the pipe surface.
This helps reduce clamping issues caused by minor size variations and improves adaptability under real job-site conditions, where pipes are not always perfectly uniform.
The anti-slip pad block design is not intended for small-diameter machines.
It is developed specifically for large FX series butt fusion machines—primarily FX800 and above—where pipe size and load conditions place higher demands on clamping stability.
At present, this design is applied only to large FX models.
The anti-slip pad blocks do not alter the fundamental butt fusion welding process.
Instead, they enhance pipe stability by improving the clamping contact interface.
This is the first time FusingX has introduced such a design on large-diameter butt fusion machines, representing a practical improvement developed directly from real on-site experience.
