Abstract: A method for expanding an end of a pipe made of plastics having shape memory with the aid of an expander tool having a tool head having an expansion member arranged to be insertable inside the end of the pipe. The method includes steps of measuring the temperature of the pipe to be expanded, adjusting at least one of the expansion control parameters of the tool head on the basis the measured temperature of the pipe, and expanding the end of the pipe utilizing the adjusted expansion control parameter of the tool head. The expander tool includes a temperature sensor for measuring temperature of the pipe to be expanded and/or ambient temperature, and an electronic control unit for adjusting at least one of the expansion control parameters of the tool head on the basis the measured temperature value.

Abstract: A tool device for expanding the end of a tube (T) includes an expansion sleeve element made of elastomeric material, the expansion sleeve element being arranged concentrically around a pull rod. A calibration sleeve is arranged concentrically around the expansion sleeve element. The inner die surface of the calibration sleeve comprises a mouth portion which has a fourth diameter (d4) which corresponds with a play to the outer diameter of the tube (T), at least one expansion die portion having a fifth diameter (d5, d6) which is larger than the fourth diameter (d4), and a shoulder between the mouth portion and the expansion die portion. The shoulder keeps the end of the tube (T), while being expanded, stationary in place inside the calibration sleeve.

Abstract: A bend fixture for bending a medium pipe comprises a body part comprising a tubular support to receive a section of a medium pipe therein, an inner bend support to allow the medium pipe to be bent about the inner bend support, and an outer bend support to support the medium pipe from an outer side of the bend to keep the medium pipe bent. The outer bend support is coupled to the body part via a hinge and is turnable between an open position to allow the section of the medium pipe in substantially straight state to be inserted into the tubular support, and a closed position to keep the medium pipe bent about the inner bend support. The bend fixture comprises a pipe coupling arrangement for coupling together the outer bend support, in its open position, and the medium pipe outside the section in the tubular support.
