In large-diameter PE pipe butt fusion welding, maintaining pipe stability is essential.
As pipe size and weight increase, even minor movement during alignment, pushing, or pressure holding can affect the welding process—especially under real jobsite conditions.
To address this, large-diameter FX series butt fusion machines are equipped with an anti-slip pad system.
The objective is simple: improve pipe stability during welding operations.
The primary role of the anti-slip pads is to enhance friction between the clamp blocks and the pipe surface.
By increasing the effective contact area, the system reduces the likelihood of pipe movement during both the alignment stage and pressure holding phase.
This feature supports the welding process from a structural standpoint.
It does not alter welding procedures, but helps maintain pipe stability throughout standard operations.
In practical construction environments, pipes are not always perfectly round or dimensionally consistent.
Minor ovality or slight deviations are common in the field.
The FX series anti-slip pads incorporate an adjustable design.
Within an acceptable tolerance range, the pads can be fine-tuned to better fit the outer pipe surface.
This improves adaptability when working with certain non-standard pipes and reduces sensitivity to real-world installation conditions.
Using the FX1000 as an example, each machine is fitted with 96 anti-slip pads.
The intention is not to increase structural complexity, but to achieve more balanced force distribution during clamping.
With multiple contact points around the pipe circumference, clamping pressure is spread more evenly.
This helps minimize localized slipping or uneven loading—factors that become increasingly important with larger pipe diameters.
The anti-slip pad system is currently applied to large-diameter models within the FX series.
The images referenced here show the actual configuration on an FX1000 machine, where the pads are positioned closely together to create a near-continuous clamping surface.
This configuration is specifically designed for large-size welding applications and is not used across all machine sizes.
The anti-slip pad system is an original structural solution developed for the FUSINGX FX series and is presently used on large-diameter butt fusion machines.
Rather than serving as an added feature for marketing purposes, it reflects a practical response to field conditions where pipe stability becomes increasingly critical as pipe dimensions grow.
