Heavy-duty pulling heads for reliable pipe pulling

Thanks to the design of our pulling heads, the pulling forces are optimally trans­ferred to the pipe and ensure that the pipe is pulled in safely. As an option, we offer seal-welded versions and drawbar eyes for up to 500 kN axial force. For use with thermowells, the pulling head can be adapted to the diameter of the thermowell.

PE 100 drawing head General prelim­inary remark The molded parts to be offered must be made of PE 100 material and comply with DIN EN 12201 or DIN EN 1555 with regard to dimen­sions, toler­ances and quality require­ments. Proof of manufacture on the basis of a quality assurance system in accor­dance with DIN EN ISO 9001 must be provided. A certificate in accor­dance with DIN EN 10204 must be provided by the manufac­turer for all molded parts. The body of the molded part must be manufac­tured from a single piece of homoge­neous semi-finished product in order to ensure the required high stability of the molded part. Semi-finished products made from winding rod are not permitted. The design of the fitting must be such that the specified maximum axial force can be trans­mitted. Sharp edges at critical load points are not permitted. In the area of the drawing eye, steel plates must be fitted on both sides of the PE base to transfer the axial force to the PE body over a large area. Screw connec­tions must be designed to prevent loosening.

    The spigot end must be designed at least for a HE butt weld.
    Versions for higher axial forces and with a larger outside diameter for use with thermowells and sealed against the ingress of drilling emulsion are possible and should be noted accord­ingly. The maximum permis­sible tensile force of the pipe and the weldability to the protective jacket must be taken into account.
    The pulling head may only be used in conjunction with a swivel bearing.
