Ipayipi yensimbi ye-LSAWisikhathi somsebenzi we-Longitudinally Submerged Arc Welding.Inezici ezilandelayo.Okokuqala, ukucaciswa komkhiqizo kuhlanganisa uhla olukhulu.Ayikwazi nje ukukhiqiza amapayipi anobubanzi obuncane nobukhulu bodonga olukhulu kodwa futhi nemikhiqizo enobubanzi obukhulu nogqinsi olukhulu lwezindonga.Okwesibili, inamandla aqinile okuvimbela ukugqwala nokuqhekeka.Iphethe ubukhulu obunembile obuphakeme futhi ilungele ukwakhiwa kwe-welding esizeni.Okwesithathu, ngenxa yenqubo yokushisela emihle, ingaba nenqubo yokushisela ezinzile kanye nekhwalithi ephezulu yokushisela.Okokugcina, kulula ukubona ukutholakala kwamaphutha angonakalisi enqubweni yokushisela.Ngenxa yalezi zinzuzo kanye nezici zayo ezikhethekile, ipayipi lensimbi le-LSAW linethemba eliqhakazile futhi abathengi abaningi bayafisa ukulisebenzisa ukuze benze imisebenzi yansuku zonke.Ngokwezinga le-API, emapayipini amakhulu okulethwa kukawoyela negesi, ipayipi lensimbi elishiselwe iwukuphela kweshubhu elikhethiwe lapho ishubhu lidlula endaweni ye-alpine, ulwandle nezindawo ezihlala abantu basemadolobheni.

Selokhu kwethulwa okulula kwepayipi lensimbi le-LSAW, lesi sihloko sizonikeza ireferensi ephathekayo mayelana nethemba lezimakethe zamapayipi ensimbi ye-LSAW ekhaya nakwamanye amazwe.Kuze kube manje, imakethe yamapayipi ensimbi ye-LSAW ikhula kakhulu ngenxa yokwanda komthamo we-LSAW yaseChina.Phakathi kwalabo bakhiqizi be-LSAW, abanye babo bazimisele ukuthenga amapayipi omthombo avela entshonalanga kuyilapho abanye abakhiqizi abahamba phambili bekhetha ukuthola ipayipi lomthombo kubakhiqizi basekhaya bezitshalo.Ngaphandle kwe-China, i-India kanye ne-Middle East nazo zinokwenyuka okusobala komthamo we-LSAW.I-China isibe yizifunda ezinkulu kakhulu zokukhiqiza ipayipi lensimbi le-LSAW.Ngokungena ku-2014, ezinye izidingo zepayipi lensimbi ye-LSAW zilindeleke.Ake sithathe iShayina njengesibonelo.Ngaphezu kwezidingo zangaphandle, i-China inesidingo esiqinile sangaphakathi kulesi sici sokwandisa ubude bepayipi legesi.

Noma kunjalo, isidingo sepayipi lensimbi ye-LSAW sibikezelwa ukuthi sizokhuphuka ngokuqhubekayo.Naphezu kweqiniso, imakethe yamapayipi ensimbi ashiselwe ingase ihlupheke ngenxa yokuqhuma okukhulu.Ngaphambilini, imakethe yamapayipi ensimbi ye-LSAW iphethwe abakhiqizi baseYurophu nabaseJapane kodwa ngokuzayo, izobhekana nokuncintisana okuqinile okuvela eNdiya naseChina.Nokho, nakuba iChina ingase ibe isifunda esikhulu kunazo zonke sokukhiqiza ipayipi lensimbi le-LSAW, izimfuno ngeke zihambisane namandla.

Ukufingqa, nakuba ipayipi lensimbi le-LSAW lingase lihlupheke ngezinkinga ezithile ezincane enqubweni yokuthuthukiswa, lisajabulela ithemba elikhanyayo nelinempilo kusukela esikhathini eside.Bobabili abathengi nabakhiqizi kufanele baqiniseke ngethemba lepayipi lensimbi ye-LSAW.
