I-DIN 30670 ibhekisela embotsheni ye-polyethylene kumapayipi ensimbi nokufakwa-Izidingo kanye nokuhlolwa.

Leli zinga licacisa izimfuneko zezingubo zasefekthri ezinezingqimba ezintathu ezikhishwe nge-polyethylene, kanye ne-polyethylene enezingqimba eziningi ezinezingqimba ezisekelwe ku-sintered ukuze kuvikelwe ukugqwala kwamapayipi ensimbi nokufakwayo.I ezinengilazi zifaneleka ukuvikelwa amapayipi ensimbi angcwatshwe noma acwilisiwe emazingeni okushisa okuklama-40 °C kufika ku +80°C. Izinga lamanje licacisa izimfuneko zama-coatings asetshenziswa kuwoIpayipi yensimbi ye-LSAW or amapayipi ensimbi angenamthungo futhiokokufaka esetshenziselwa ukwakhiwa kwamapayipi okuthutha uketshezi noma amagesi.Ukusebenzisa leli zinga kuqinisekisa ukuthi i-PE coating inikeza ukuvikeleka okwanele ngokumelene nemithwalo yemishini, eshisayo neyamakhemikhali eyenzekayo ngesikhathi sokusebenza, ukuthutha, ukugcinwa nokufakwa.I-DIN EN ISO 21809-1 icacisa izidingo ezingeni lamazwe ngamazwe zezendlalelo ezintathu ze-polyethylene extruded- kanye ne-polypropylene-based yamapayipi ensimbi wezinhlelo zokuthutha ze-petroleum negesi yemvelo.Izinkambu ezilandelayo zesicelo azimboziwe yi-DIN EN ISO 21809-1:─zonke izigqoko ezisekelwe ku-polyethylene zamapayipi ensimbi nokufakwa okusetshenziselwa ukudlulisa nokusabalalisa amanzi namanzi angcolile,─zonke izigqoko ezisekelwe ku-polyethylene zamapayipi ensimbi nokufakwa kumapayipi okusabalalisa wemidiya yegesi neyoketshezi,─I-polyethylene-based-sintered-based-multi-layer-based coatings yamapayipi ensimbi nokufakwa okusetshenziselwa amapayipi okuthutha namapayipi okusabalalisa Izinga lamanje lihlala lisebenza kule mikhakha engenhla yokusetshenziswa.Izingubo ezinezingqimba ezimbili ze-polyethylene zisezingeni laseYurophu ku-DIN EN 10288 eyashicilelwa ngoDisemba 2003.

Izinto ezisetshenziswayo zizokhethwa ngokubona kwe-coater ngoba, kuye ngenqubo yokufaka nokugqoka, izinto ezihlukahlukene zingasetshenziswa ukuze zihambisane nezidingo ezincane ezichazwe kuleli zinga lokugqoka okuphelile.Noma yiziphi izidingo ezichezukayo zomthengi mayelana nezinto ezizosetshenziswa zizoba ngaphansi kwesivumelwano.Indawo engaphezulu izolungiswa ngokususa ukugqwala ngendlela yokuhlanza ukuqhuma.Ukuhlanza ukuqhuma kanye nanoma yimuphi umsebenzi olandelayo odingekayo ngeke kubangele ukuncishiswa kobukhulu obuncane bodonga oluchazwe kumazinga okulethwa kwezobuchwepheshe wepayipi yensimbi.Uthuli oluncibilikayo olusele luzosuswa ngaphambi kokumbozwa.
