<p>The method involves providing a cylindrical or conical tube body, and forming an aperture (12) and a nut. The nut is disconnected in a process by the aperture in a lateral surface of the tube body. A profile material is inserted in the nut, and is fixed in the tube body. The aperture is formed with an elongated contour, particularly in an axial direction (A) of the tube body. An independent claim is included for a steam filter with a cylindrical or conical tube body with an aperture.</p> |
