ABSTRACT:
A method and means for connection of crosswisely extending pipe connections at a longitudinally extending transport pipe for fluid, gas or similar media. The method and the means involves the attachment of two separate parts in an embracing relationship to the transport pipe, thus forming a body for the connection means, said body including a guiding channel directed towards the transport pipe and in which a hole piercing member is movably arranged, the hole piercing member being arranged to take up a hole under the influence of an applied force. The guiding channel communicates with one or more flow channels leading to pipe connection members at the outside surface of the body, the hole piercing member serving as a valve seat and the edge of the hole serving as a valve face, the hole piercing member being arranged with an adjusting member for movement in direction to and from the hole in the wall of the transport pipe, thus acting as a flow restricting valve for flow from the transport pipe to pipes connected to the pipe connection members.
