Ring flexibilityAccording to the requirements of ÖNORM EN 13476-3, the ring flexibility is 30%.Test procedure according to ÖNORM EN 1446.Due to their flexibility the PP-MEGA-Pipes adapt slightly to the trench. Usingpolypropylene, a flexible thermoplastic raw material, slight curves can be made.Abrasion resistance of polypropylenePipes made of polypropylene have one of the highestabrasion resistances among all piping materials. Thisresults from the survey of Darmstadt-method.A piece of pipe with 1 m length is filled up to half with amixture of silica sand, gravel and water with a particle sizeof 0-30 mm and then shut with front plates on either side.Subsequently, the pipe is inclined by 45° alternating upand down. By the flow of the test material, the requiredabrasion effect is created.Assessment background for long-term deformation of the pipeThe assessment background is due to the following conditions:Placing depth: 0.8 – 6.0 mTraffic load: embeddedAggregation “Good”:The grainy underground has to be put into thelaying zone and compacted. Then thebase has to be put in, in layers ofmax. 30 cm and has to compacted carefully.The pipe has to be covered with a layer of min.15cm. The trench has to be filled with soil andhas to be compacted. The typical values of theProctor-standard density is over 94%.pipe deformation (%)ring stiffness (SN)Aggregation „none“,not recommendedAggregation „middle“Aggregation „good“Aggregation “middle”:The grainy underground has to be put into the laying zone, with max 50 cm thickness, and layer hasto be compacted carefully. The pipe has to be covered with a layer of min 15 cm. The trench has to befilled with soil and has to be compacted. The typical values of the Proctor-standard density isbetween 87% and 94%.Other placing depths on inquiry.
