An irrigation pipe (10) with a plurality of connector elements (14) adapted for attachment of lateral branches thereto, where the connector elements (14) are integrally fitted to the pipe's wall during the manufacture. Connector elements (14) may be fitted open and be adapted for closing after manufacture if not intended for use, or may be fitted closed and be adapted for opening after manufacture to enable the attachment.A method of production of such irrigation pipe (10) from a strip of flexible weldable or bondable material includes fitting integrally the connector elements (14) to predetermined locations on the strip, with or without punching the strip； bending or twisting the strip so as to juxtapose or overlap lateral edges thereof； and welding or bonding integrally the edges so as to obtain a closed pipe section.
