Izinto eziluncedo zokusebenzisa iPolyurethane Lined Pipe kwi-Double Submerged Arc Welded (DSAW) EN10219 Izicelo zePipeline

Ekuqaleni,umbhobho owenziwe nge-polyurethaneyaziwa ngokugqwesa kwayo ukumelana nokunxiba kunye nokudleka.I-polyurethane lining isebenza njengesithintelo sokukhusela, ukuthintela indawo yangaphakathi yombhobho ukuba ingagqwaliswa ngama-abrasives ahamba ngombhobho.Oku kubaluleke ngakumbi kwizicelo zemibhobho ye-DSAW EN10219 njengoko imibhobho ihlala ivezwa kulwelo lwesantya esiphezulu kunye namasuntswana aqinileyo.Ngokusebenzisa imibhobho ene-polyurethane, iinkampani zinokunciphisa kakhulu ukuphindaphinda kokugcinwa kunye nokulungiswa kweendleko, okukhokelela ekugcinweni kweendleko ezibalulekileyo kwixesha elide.

Ukongezelela, umbhobho owenziwe nge-polyurethane unikezela ukuguquguquka okuphezulu kunye nokuqina xa kuthelekiswa nezinye izinto zombhobho.Inkqubo ye-arc welding ephindwe kabini esetyenziselwa ukwenza imibhobho ye-EN10219 iphumela kwisakhiwo sombhobho ongenamthungo kunye namandla aphezulu.Idityaniswe neempawu eziguquguqukayo kunye ne-elastic ze-polyurethane, inkqubo yemibhobho ebangelwayo iyakwazi ukumelana nobushushu obugqithisileyo kunye nomthwalo onzima, okwenza kube yinto efanelekileyo yokufuna izicelo zoshishino.Oku kudityaniswa kwamandla kunye nokuguquguquka sizathu esibalulekileyo sokuba kutheni umbhobho owenziwe nge-polyurethane lukhetho lokuqala lwe-DSAW EN10219 izicelo zemibhobho.

Ukongeza kwiimpawu zabo ezibonakalayo, iipayipi ezenziwe nge-polyurethane nazo zinconywa ngenxa yeenzuzo zazo zokusingqongileyo.I-Polyurethane lining i-inert yekhemikhali, oku kuthetha ukuba ayiyi kusabela ngezinto ezihanjiswa ngemibhobho.Oku akuncedi kuphela ukugcina ukucoceka kwezinto eziqulethweyo, kwakhona kuthintela izinto eziyingozi ukuba zikhutshwe kwindawo.Njengoko imimiselo yokusingqongileyo iya isiba ngqongqo ngakumbi, ukusebenzisa imibhobho ene-polyurethane-lined kunokunceda iinkampani ziqinisekise ukuthotyelwa kunye nokunciphisa indawo yazo yendalo.

Ekugqibeleni, iipayipi ezifakwe kwi-polyurethane ziyaziwa ngokukhululeka kwazo kokufakela kunye nokugcinwa.Ulwakhiwo olungenamthungo lwemibhobho ye-DSAW EN10219 edityaniswe neempawu ezikhaphukhaphu ze-polyurethane ivumela ukufakwa ngokukhawuleza nokulula.Ukongeza, umphezulu we-polyurethane liner ogudileyo wangaphakathi unciphisa ukwakheka kwentlenga kwaye unciphise ukukhuhlane, okukhokelela ekuhambeni okusebenzayo kunye nokusetyenziswa kancinci kwamandla.Oku kuthetha iindleko eziphantsi zokusebenza kunye nemveliso ephezulu yemisebenzi yoshishino exhomekeke kwimibhobho ye-DSAW EN10219.

Isishwankathelo, iingenelo zombhobho owenziwe nge-polyurethane zenza kube lolona khetho lubalaseleyo kwizicelo zemibhobho ye-EN10219 entywiliselwe ngaphantsi kwe-arc edibeneyo.Ukunxiba kwabo kunye nokunganyangeki kwe-corrosion, ukuguquguquka kunye nokuqina, ukulungelelana kokusingqongileyo, kunye nokulula kokufakela kunye nokugcinwa kubenza babe yimathiriyeli yombhobho yokuzikhethela kwiindawo ezinzima zoshishino.Njengoko itekhnoloji iqhubeka nokuhambela phambili kunye nemigangatho yoshishino iyaguquka, silindele ukubona ukuthembela okwandisiweyo kwimibhobho ene-polyurethane-lined kwiminyaka ezayo.
