Pipes may be supplied tocustomer requirements in either smalldiameter pipe in coil lengths up to9500m, or in straight lengths up to PE pipes are robust, flexible, andoffer the installer many cost savingadvantages.

4 Whilst they are resistant tosite damage, normal care and goodhousekeeping practices are necessary toensure trouble free of Vinidex PE pipes is madeeasier due to the light weights of bothcoiled and straight length pipe. Caremust be exercised however, to avoiddamage to the pipe walls, pre-assembledend fittings, or sub aspects need to be addressed, asthe nature of PE pipes is such that incold and wet weather the pipes becomeslippery and difficult to handle. In thesecircumstances, additional care should beexercised when handling coils or bundlesof pipe. In hot weather, especially withblack pipes, the pipe surface may reach70 C, when the ambient temperaturesreach 40 C. Handling PE pipes at thesetemperatures requires gloves, or otherprotection, to prevent the possibility ofskin slings are recommended for liftingand handling PE pipe in order to wire ropes or chains are used,then all of the contact points between theslings and the pipe must be protected bysuitable padding.

5 Where pipes are incoils, the slings must be placed evenlyaround the entire coil. Similarly, wherecoils or straight lengths are lifted by forklift the contact points must be lifting coils, the lifting must beperformed on the entire coil, and the forklift tynes not inserted into the coilwinding. When lifting packs of pipes, thetynes must be placed under the entirepack, and the tynes not pushed into thepack. Pipes must not be lifted by placingmetal hooks into the ends of conditions approaching freezing, theimpact resistance of PE reduces, andcare must be exercised to preventdamage during lengths greater than 6 metresshould be lifted using a spreader bar, andwide band slings. PE pipes will flexduring lifting, and care needs to beexercised to prevent damage to pipes orend fittings arising from contact with theground.

6 Care needs to be taken to centrethe pipe in the reduction in the pipe wall thickness ofup to 10% may be tolerated. However,sections with sharp notches should berejected, or the damaged area buffed outto remove the sharp pipes stacked for transport must beevenly supported in order to preventdistortion. All bearing surfaces must befree from contact with sharp objects. Anyprojecting sections such as stub flangesmust be supported to prevent straight lengths of pipe, suitablesupport beneath the pipes is provided bybeams of minimum width 75 mm,spaced horizontally at m centres. Forrectangular stacks, additional verticalsupports at 3 metre spacing should beused. For pyramid stacks, the bottompipe layers also need to be chocked toprevent stack large diameter pipes (DN 630 andabove) it may be necessary to tom, orinternally support the ends of the pipe inorder to prevent end treatments such as flangesare applied in the factory, thesetreatments must be protected coils are stacked vertically thestacks may need to be restrained inorder to prevent the bottom section ofthe coil being flattened or Warehouse Group Pty 1300 661 417PE Pipe Systems PE Pipe Systems PE Pipe Systems PE Pipe Systems PE Pipe Systems PE Pipe Systems PE Pipe Storage HeightStraight LengthsPE MaterialHeight (m)Height (m)up to SDR 21above SDR 21 MDPE (PE63, PE80B) (PE80C, PE100) diameter mmCoil stacks (number)up to 32550, 63490, 1102 Note.
