Umbhobho odityaniswe ngobude obude obubanzi obukhulu ligama eliqhelekileyo. Iveliswa ngentsimbi yentsimbi. Imibhobho edityanisiweyo ngezixhobo ze-welding ze-high-frequency zibizwa ngokuba yi-longitudinally welded pipes. (Igama linikwe ngenxa yokuba iiweldi zombhobho wentsimbi zikumgca othe tye). Phakathi kwabo, ngokweenjongo ezahlukeneyo, kukho iinkqubo ezahlukeneyo zokuvelisa umva. (Izahlulwe ngokuqikelelwa kumbhobho wesikafula, umbhobho wolwelo, isingxobo socingo, umbhobho wesibiyeli, umbhobho wesitrayile, njl.njl.)

Ngokubanzi,imibhobho yentsimbi yomthungo ethe tyekunye nobubanzi obungaphezulu kwe-325 kuthiwa yimibhobho yentsimbi enobubanzi obukhulu. Inkqubo yokudibanisa i-welding ye-arc ye-welding ye-arc ene-arc ene-arc ene-diameter enkulu-engqindilili-ngodonga lombhobho wentsimbi, iteknoloji ye-welding ye-arc, kunye ne-welding manual nayo inokuqhutywa emva kokuba umbhobho wentsimbi usenziwe. Indlela yokuhlola ngokubanzi kukubona iziphene. Emva kokuba isiphene sifunyenwe, sinokuhanjiswa. Iimveliso ezikumgangatho ophantsi kufuneka zidityaniswe kwakhona. Imibhobho yentsimbi yomthungo etyebileyo enobubanzi obukhulu, ilungele ukuthuthwa kolwelo, ukuxhasa izakhiwo zentsimbi, kunye nemfumba. Zisetyenziswa kakhulu kwi-petrochemical, ukwakhiwa, ubunjineli bamanzi, ishishini lamandla, ukunkcenkceshela kwezolimo, ukwakhiwa kwedolophu, njl. Umbhobho wentsimbi kufuneka ukwazi ukumelana noxinzelelo lwangaphakathi, kwaye uqhube uvavanyo loxinzelelo lwe-2.5Mpa, kwaye uyigcine ngaphandle kokuvuza. umzuzu omnye. Indlela yokufumanisa impazamo yangoku ye-eddy ivumelekile ukuba ithathe indawo yovavanyo lwe-hydraulic. Iindlela zokubumba ikakhulu ziquka i-UOE, i-RBE, i-JCOE, njl., phakathi kwayo i-JCOE inezinga eliphezulu lokusetyenziswa. Isiphelo sombhobho sinokudityaniswa ngokweemfuno zabathengi, ebizwa ngokuba yi-threaded and unthreaded.

Inkqubo yemveliso yombhobho wentsimbi womthungo omkhulu onqamlezileyo:

Inkqubo yokuvelisa imibhobho yentsimbi yomthungo emikhulu enobubanzi obucacileyo ibandakanya iindlela zokuvelisa ezifana nokuqengqeleka okushushu, ukujijwa okushushu, nokuphosa. Imibhobho yentsimbi enobude obutyebileyo enodonga ngokubanzi isebenzisa iinkqubo zokuvelisa i-arc entywiliselweyo. Iimveliso zigobile, zidibene, zifakwe ngaphakathi, kwaye zicutshungulwa ngaphandle. I-Welding, ukulungiswa, i-flat heading, kunye nezinye iinkqubo zihlangabezana neemfuno zemigangatho yepetrochemical.

Ukusetyenziswa kwemibhobho yentsimbi yomthungo ebanzi enobubanzi obukhulu isetyenziswa ikakhulu kumalungu axhasa umzimba, njengokufumba kwebhulorho, ukufunxa imfumba ye-subsea, kunye nemfumba yesakhiwo esiphakamileyo.

Izinto ezisetyenziselwa imibhobho yentsimbi yomthungo ebanzi yobubanzi obukhulu ngokuqhelekileyo iQ345B kunye neQ345C. I-Q345D ikwasetyenziswa kwiindawo ezinobushushu obuphantsi. I-Q345E imibhobho yentsimbi yomthungo emikhulu enobubanzi obukhulu isetyenziswa ikakhulu kulwakhiwo lwesakhiwo sentsimbi.
