Bedding requirements for PE pipe

May 31, 2018PE pipes having a protective outer sheath (multi-layer) may be laid in heterogeneous ground without sand bedding thus allowing a wide range of excavated materials to be re-used. Where the pipe is to be laid through rock or ground of variable consistency, customers normally advise that the trench should be excavated approx. 75mm below its normal depth, and a bedding material placed before the pipe to provide a bed Can PE pipe be laid in heterogeneous ground?Can PE pipe be laid in heterogeneous ground?PE pipes having a protective outer sheath (multi-layer) may be laid in heterogeneous ground without sand bedding thus allowing a wide range of excavated materials to be re-used.Bedding requirements for PE pipe What is pipe bedding factor?What is pipe bedding factor?The pipe bedding factor is very important as this adds a great deal of strength to the pipe when it is in service.
