Ukubaluleka kokukhula kwe-mustitudinal seam engaphantsi kwe-arc yelokhwe

Okwangoku, imibhobho ikakhulu isetyenziselwa ukuhambisa umgama omde kunye negesi. Imibhobho yentsimbi yentsimbi esetyenziswe kwimibhobho yomgama omde ibandakanya ikakhuluI-SPIRAL i-arc ephantsi i-arc yensimbi yentsimbikunye ne-seam ethe tye-i-arc efakwe i-arc ye-welc yensimbi. Ngenxa yokuba i-Picmaral Arc i-Piped Peped Pipe yenziwe ngentsimbi yomthi kunye nobunzima bayo bunqongophele, ukuphuculwa kwebanga lensimbi kunomda wokunyanga ubushushu bezinto ezibonakalayo. Ukongeza, kukho ezinye zeentsilelo ezingenakuthelekiswa nanto ze-Picral Armmed Proped Peped Peped Peped Peped Peped Peper, enje nge-ILDE ende, uxinzelelo olukhulu lwentsalela kunye nokuthenjwa kakubi kwe-weld. Ngokwanda kweemfuno zemibhobho ye-oyile kunye negesi, azisasebenzi kwiindawo ezinabantu abaninzi kunye neendawo ezineemfuno eziphezulu zokuxhomekeka, kwayeImiphetho emikhulu ye-weldiedngokuthe ngcembe ithatha indawo yemibhobho ye-welf.

Kutshanje, i-China ikhawulezisa uphuhliso lweoyile kunye negesi kwi-East East chine. Ngokuphuhliswa kwe-oyile enzonzobileni yolwandle, umbhobho obekwe elunxwemeni uchatshazelwa yimikhosi edibeneyo yengcinezelo, kunye ne-pronomenon ye-themeding isavela, eli lithuba elibuthathaka le-SPILD umbhobho. Ukwenzela ukuphucula umbhobho wokuThuthwa kwePipeliel kwaye uqiniseke ukuba umbhobho we-submarmarine uphulukene nodonga oluqinileyo, umbhobho wenqanawa ongaphantsi komhlaba makabe nobuqhetseba. Ke ngoko, xa kuthelekiswa nombhobho we-spiral welding, umbhobho othe tye othe tye une-welding ephezulu yokuchaneka kunye nokulungisa i-welding ephezulu, kunjalo kule nkalo, umbhobho we-Weldied ngokuthe tye kukhetho lokuqala.

Oomatshini, ukwakhiwa, ishishini lekhemikhali kunye namanye amashishini kufuneka afune imibhobho ye-welded. Okwangoku, umngxunya ongaphakathi wesihlalo se-vave sifakwe kwishishini lomatshini, elisetyenziselwa ukusebenza ngokwasemsebenzini, ukutya okuthe gabalala kunye nokuchitha izinto. Ukuba kusetyenziswa umbhobho we-welding ye-Welding ye-Welding, kuya kuba noqoqosho ngakumbi. Ukongeza, ngenxa yeemfuno zepropathi yoomatshini yokuntywila, imibhobho ye-Weldied kuphela esetyenziselwa ukwakha imibhobho; Umbhobho othe tye othe nkqo kulindeleke ukuba isetyenziselwe imibhobho yekhemikhali.
