Abstract: A tube structure for attachment to an irrigation pipe for non-erosively distributing water from the pipe to the ground, the tube comprising a shapeable, deformable tubular first end portion, a plurality of retainer hooks secured to said first end portion and a second tubular end portion. A pair of spaced diffuser screens are positioned in, and extend transversely across, the second end portion of the tube.

Abstract: Apparatus for removing anomalies from pipe comprising an elongated framework, an elongated carriage reciprocally mounted on said framework, means for supporting an elongated pipe section spaced over said carriage for reciprocating movement with said carriage and rotational movement about the longitudinal axis of the pipe section, means for exerting force in a radially outward direction against the internal walls of a pipe section reciprocated by said carriage into a position surrounding said force exerting means, and extensible means connected to said force exerting means facilitating reciprocal movement of said force exerting means within a pipe section positioned therearound.
