Chitoliro chachitsulo cha LSAWndi nthawi yaukadaulo ya Longitudinally Submerged Arc Welding.Lili ndi zotsatirazi.Choyamba, tsatanetsatane wa mankhwala amakwirira osiyanasiyana.Sizingangopanga mapaipi okhala ndi mainchesi ochepa komanso makulidwe akulu akulu komanso zinthu zokhala ndi mainchesi akulu komanso makulidwe akulu akulu.Chachiwiri, ili ndi mphamvu zoletsa dzimbiri komanso kusweka.Ili ndi miyeso yolondola kwambiri ndipo ndiyosavuta kumanga pamasamba.Chachitatu, chifukwa cha njira yabwino yowotcherera, imatha kukhala ndi njira yowotcherera yokhazikika komanso kuwotcherera kwapamwamba.Pomaliza, ndikosavuta kuzindikira zolakwika zomwe sizingawononge pakuwotcherera.Chifukwa cha zabwino izi komanso mawonekedwe ake apadera, chitoliro chachitsulo cha LSAW chili ndi chiyembekezo chowala ndipo ogula ambiri akufuna kutengera ntchito zatsiku ndi tsiku.Malinga ndi muyezo wa API, m'mapaipi akulu operekera mafuta ndi gasi, chitoliro chachitsulo chowotcherera ndicho chokhacho chosankhidwa chubu pamene chubu chimadutsa kudera lamapiri, nyanja ndi madera okhala ndi mzinda.

Kuyambira kuyambika kosavuta kwa chitoliro chachitsulo cha LSAW, nkhaniyi idzapereka chidziwitso cha konkire ponena za chiyembekezo cha misika ya LSAW yachitsulo kunyumba ndi kunja.Mpaka pano, msika wa chitoliro chachitsulo cha LSAW ukuchulukirachulukira chifukwa chakukula kwa mphamvu yaku China LSAW.Pakati pa opanga LSAW, ena mwa iwo ndi okonzeka kugula mapaipi opangira kuchokera kumadzulo pomwe opanga ena otsogola amakonda kupeza chitoliro kuchokera kwa opanga mbewu zakumaloko.Kupatula China, India ndi Middle East alinso ndi kukwera kowonekera kwa LSAW.China wakhala zigawo zazikulu zopangira LSAW zitsulo chitoliro.Kulowa 2014, zofunika zina mu LSAW zitsulo chitoliro akuyembekezeredwa.Tiyeni titenge China monga chitsanzo.Kuphatikiza pa zofuna zakunja, China ili ndi kufunikira kwamphamvu mkati mwa gawo ili pakukulitsa kutalika kwa payipi ya gasi.

Lang'anani, kufunikira kwa chitoliro chachitsulo cha LSAW kukuyembekezeka kukwera mosalekeza.Ngakhale zili choncho, msika wamapaipi wachitsulo wowotcherera ukhoza kuvutika ndi kugunda kwakukulu.Poyamba, LSAW zitsulo msika chitoliro likulamulidwa ndi opanga European ndi Japanese koma m'tsogolo, izo kukumana mpikisano wamphamvu ku India ndi China.Komabe, ngakhale kuti China ikuyenera kukhala dera lalikulu kwambiri lopangira chitoliro chachitsulo cha LSAW, zofuna sizingagwirizane ndi mphamvu.

Pomaliza, ngakhale chitoliro chachitsulo cha LSAW chikhoza kuvutika ndi mavuto ang'onoang'ono pakupanga chitukuko, chimakhalabe ndi chiyembekezo chowala komanso chathanzi kuyambira nthawi yayitali.Onse ogula ndi opanga ayenera kukhala otsimikiza ndi chiyembekezo cha LSAW chitoliro chachitsulo.
