摘要： A method to establish flow communication with a tubular pipe (3), and a device for utilization of the method, whereby two housing members (6, 7) are joined in a sealing contact position embracing the tubular pipe (3), whereafter a piston member (1), movably arranged in one housing member (6), having a towards the center of the pipe (3) directed chisel-shaped part (2) extending in a parallel relationship to the length axis of the tubular pipe (3), is brought to move towards the pipe (3) by application of a force and to penetrate through its wall, thereby creating a through slot extending in longitudinal direction of the pipe (3), the edge portions of said slot extending in longitudinal direction of the pipe (3) and being bent into a position directed towards the inside surface of the pipe (3), an adjustment member (5) also being arranged, whereby the piston member (1) can be moved in direction to and from the slot taken up in the pipe (3), thereby faciliating desired adjustment of the flow communicating area with the pipe (3), a channel (9) being arranged in the housing member (6) adjacent to the movable piston member (1), arranged to faciliate flow communication with said pipe (3) from existing opening in the slot taken up in the pipe (3).
