Uyilo lombhobho wentsimbi yobunjineli bolwandle kunye nokukhethwa, ukucaciswa kuhambelana nokuhlelwa kolwakhiwo lwentsimbi yobunjineli bolwandle, kwaye ngokubhekisele kwi-API (iziko lepetroleum yaseMelika), i-AISC (uluntu lwaseMelika lwesakhiwo sentsimbi), i-ASTM (uluntu lwaseMelika lovavanyo kunye nezixhobo). ), i-ANSI (i-American standard standards Institute), i-ASTM (uluntu lwaseMelika lokuvavanya kunye nezinto eziphathekayo), i-AWS (i-American welding society), i-NACE (umbutho wesizwe weenjineli ze-corrosion) kunye nezikhokelo. Ukufuna izixhobo zombhobho wentsimbi yobunjineli bolwandle, ngokusisiseko yimfuneko yepleyiti yentsimbi ngokwayo, inentsimbi ephantsi yekhabhoni, intsimbi enamandla amakhulu, intsimbi eyomelele kakhulu, intsimbi engatyiwa ngamacandelo amane. Chaza amanqaku amabini apha:
(1) injineli yolwandle yezixhobo ezisuka kumazwe angaphandle kakhulu. Ngamanye amaxesha kwityhubhu yentsimbi yaseBritani kunye nokuveliswa kwetyhubhu yentsimbi kubaluleke kakhulu kwiimfuno zomgangatho ophezulu. Kubunjineli bolwandle buyindawo ekhethekileyo yetyhubhu yensimbi, i-100% yayo yonke imfuneko yovavanyo lwe-weld ultrasonic (UT - Ultrasonictesting) kunye nokuhlolwa kwamagnetic (MT - Magnetictesting). Kufakwe kwisakhiwo esiphambili sombhobho wensimbi, kuluhlu lwe-300 mm kuzo zombini iziphelo ze-longitudinal seam zifuna i-100% UT kunye ne-MT.
(2) ukuveliswa kwenode yombhobho kumxholo obalulekileyo kubunjineli bolwandle. Iifektri zombhobho ezikhethekileyo phesheya, kunye nezasekhaya zakhiwe iyunithi. Umthamo weetoni ze-52000, umzekelo, "ubuhlobo" bolwandle lwe-bohai, iyunithi yokugcina imveliso edadayo (FPSO, kunye nokuqeqesha enye yeenqanawa eziphezulu ezilishumi ezidumileyo zaseTshayina) zengalo ekhethekileyo ethambileyo nje (YOKE) inkqubo ye-YOKE kunye nesibiyeli senkxaso, itotshi, inkxaso yeqonga le-helicopter, njl. Kukho iindawo ze-221, ukuhlangabezana neemfuno ze-AISC, i-AWS. Umbhobho omde we-59 km (kubandakanywa ityhubhu yolawulo olude ye-hydraulic eyi-28 km, i-119 yevalve yokulawula ekude, idekhi yetanki engama-48). Indawo yeenqanawa ukuze kuqinisekiswe umgangatho wolwakhiwo, khetha kumawaka eewelder ezininzi zokuwelda okugqwesileyo, i-15 yokugqibela ifaneleka njenge-6 gr yoluntu lokuhlelwa. Kwinjineli yolwandle ukuze kuthintelwe ukuvuza kwe-oyile kunye negesi kwinkqubo, ayimkelwanga uqhagamshelo lwentsimbi yombhobho wentsimbi, kwaye yamkele i-argon arc welding. Amaqela amathathu e-TIG welder shipyard kwaye adinga uqeqesho olukhethekileyo.
