Corresponds to the pull-out directional support strength of steel pipe piles! Construction time is about 1/3 of welding, with a simple process.
The "ECS-PJ" is a non-welded joint construction method that interlocks the lower and upper piles and fits the outer and inner rings using a hydraulic jack. It possesses strength equivalent to welding while allowing for construction under various conditions and reducing construction time. It can be used as a joint for general small-diameter steel pipe piles. 【Features】 ■ The points for construction management are clear and easy to manage, eliminating the need for skilled welders. ■ Usable in sites such as chemical plants where open flames are prohibited and underwater bridge piers. ■ Quality remains stable regardless of the skills of welders or site conditions. ■ Since welding is not required, construction can be carried out consistently regardless of weather conditions such as wind and rain. ■ Connections can be made close to the ground surface, reducing the number of joints in low pile head sites. ■ No welding fumes are generated, preventing pneumoconiosis and protecting the health of workers. *For more details, please refer to the PDF materials or feel free to contact us.
