Izinzuzo Zokusebenzisa Ipayipi Elilayini Le-Polyurethane Ku-Double Submerged Arc Welded (DSAW) EN10219 Pipeline Applications

Okokuqala,ipayipi elifakwe nge-polyurethaneyaziwa ngokumelana kwayo okuhle kakhulu nokugqoka nokugqwala.I-polyurethane lining isebenza njengesithiyo esivikelayo, esivimbela indawo yangaphakathi yepayipi ukuthi ingagqwali ngenxa ye-abrasives egeleza epayipini.Lokhu kubaluleke kakhulu ezinhlelweni zamapayipi ze-DSAW EN10219 njengoba amapayipi avamise ukuchayeka kuketshezi lwesivinini esikhulu kanye nezinhlayiya eziqinile.Ngokusebenzisa amapayipi anemigqa ye-polyurethane, izinkampani zinganciphisa kakhulu imvamisa yokugcinwa nokulungiswa okubizayo, okuholela ekongeni kwezindleko ezibalulekile ngokuhamba kwesikhathi.

Ukwengeza, ipayipi elifakwe nge-polyurethane linikeza ukuguquguquka okuphakeme nokuqina uma kuqhathaniswa nezinye izinto zamapayipi.Inqubo yokushisela i-arc engaphansi kwamanzi ephindwe kabili esetshenziselwa ukwakha amapayipi e-EN10219 iphumela esakhiweni sepayipi esingenamthungo nesinamandla aphezulu.Kuhlanganiswe nezinto eziguquguqukayo nezinwebekayo ze-polyurethane, uhlelo lwamapayipi oluvelayo luyakwazi ukumelana namazinga okushisa aphakeme kanye nemithwalo esindayo, okwenza kube kuhle ekufuneni izicelo zezimboni.Le nhlanganisela yamandla nokuguquguquka yisizathu esibalulekile sokuthi kungani ipayipi elifakwe i-polyurethane libe yisinqumo sokuqala sezinhlelo zokusebenza zamapayipi e-DSAW EN10219.

Ngaphandle kwezakhiwo zabo ezibonakalayo, amapayipi ane-polyurethane-lined nawo anconywa ngezinzuzo zawo zemvelo.I-polyurethane lining ayisebenzi ngamakhemikhali, okusho ukuthi ngeke isabele ngezinto ezithuthwa ngamapayipi.Lokhu akusizi nje ukugcina ubumsulwa bokuqukethwe, futhi kuvimbela izinto eziyingozi ukuthi zingakhishelwa endaweni ezungezile.Njengoba imithetho yezemvelo iba ngokuqina, ukusebenzisa amapayipi ane-polyurethane-lined kungasiza izinkampani ziqinisekise ukuthobela futhi zinciphise indawo yazo yemvelo.

Okokugcina, amapayipi anemigqa ye-polyurethane ayaziwa ngokulula kwawo ukufakwa nokugcinwa kwawo.Ukwakhiwa okungenamthungo kwamapayipi e-DSAW EN10219 kuhlanganiswe nezakhiwo ezingasindi ze-polyurethane kuvumela ukufakwa okusheshayo nokulula.Ukwengeza, indawo engaphakathi ye-polyurethane liner ebushelelezi inciphisa ukunqwabelana kwenhlabathi futhi inciphise ukungqubuzana, okuholela ekugelezeni okuphumelelayo nokusebenzisa amandla okuphansi.Lokhu kusho izindleko eziphansi zokusebenza kanye nokukhiqiza okuphezulu kwemisebenzi yezimboni encike kumapayipi e-DSAW EN10219.

Kafushane, izinzuzo zepayipi elifakwe ulayini we-polyurethane zenza kube ukukhetha okuhle kakhulu kumapayipi afakwe ngaphansi kwe-arc ashiselwe izicelo ze-EN10219.Ukumelana nokuguga nokugqwala, ukuguquguquka nokuqina, ubungane bemvelo, kanye nokufakwa kalula nokugcinwa kokunakekelwa kubenza babe yimpahla yamapayipi ekhethwayo ezindaweni ezibucayi zezimboni.Njengoba ubuchwepheshe buqhubeka nokuthuthuka namazinga emboni ayashintsha, silindele ukubona ukwethembela okwengeziwe emapayipini ane-polyurethane-lined eminyakeni ezayo.
