摘要： The present invention concerns a method to monitor the cooling process in a welded joint during the welding of pipes (1) of a weldable polymer material, where the welding process comprises that a muff (7) of a weldable polymer material is placed with overlap over the end of the pipe, and that an electrically conducting tape (9) is placed between the pipe and the muff, that the muff is held in place by welding equipment (19) that makes contact with the muff, and that the muff is welded to the pipe through an electrical current being supplied in order to heat the tape and the surrounding polymer material in order to form a welded joint, where a measurement process is carried out after the welding process has ended comprising that a current pulse Ip is supplied to the tape from an indicator unit (40), a resulting temperature-dependent parameter Sp in the tape is determined by the indicator unit, the value of Sp is stored in the indicator unit, that a further current pulse Ip is supplied to the tape from the indicator unit after a predetermined time interval, and that the parameter Sp in the tape is determined and the value of Sp is stored in the indicator unit, the indicator unit monitors and evaluates the value of the parameter Sp or the relative change in the value of the parameter Sp, the measurement process is repeated until Sp reaches a plateau value or the relative change in Sp reaches a predetermined level, a signal arrangement signals that the welding equipment can be removed from the area of the weld when the indicator unit (40) indicates that the cooling process has ended. The invention concerns also an arrangement for monitoring the cooling process during the welding of pipes of a weldable polymer material.

摘要： A method for installation and repair of insulated piping includes placing a sleeve coupling, made of a weldable polymer material incorporating a slit that runs lengthwise along the piping, and whose length exceeds the distance between the outer pipes' ends, over the exposed section of the inner pipe so as to overlap the ends of the outer pipes, and welding the sleeve coupling to the outer pipe at the ends of the outer pipes, by placing an electrically conductive band between the outer pipe and the sleeve coupling, ensuring that free ends of the band project upward through the slit. A power converter which has a quasi-resonant converter is employed to produce the electric current that is to be connected to the band.

摘要： Pipes of a weldable polymer material are welded with a muff of a weldable polymer material. The method includes placing the muff with an overlap over the ends of the pipes, welding the muff to the ends of the pipes through placement of an electrically conducting band that is permeable to molten plastic between the pipe and the muff, connecting a power supply to the band through feed cables, and supplying an electrical current in order to heat the band and the surrounding polymer material such that they melt together around the band in order to form a weld. The temperature of the weld is calculated through adding the initial ambient temperature of the weld and the increase in temperature of the band.
