Kwishishini leoli kunye negesi, ukubaluleka kwenkqubo yokubhobhoza ethembekileyo nesebenzayo ayinakunyanzeliswa.Izinto ezahlukeneyo kunye neenkqubo kufuneka zihanjiswe ngemibhobho, ukwenza ukhetho lwemibhobho lubaluleke kakhulu.Kukho iintlobo ezimbini eziphambili zemibhobho esetyenziswayo kweli shishini: imibhobho engenamthungo kunye nemibhobho edityanisiweyo.Kweli nqaku, siza kugxila kwinkqubo yokuvelisa kunye nokusetyenziswa kweAPI 5L PSL1&PSL2 GR.B X42 X46 X52 X60 X65 X70 imibhobho yentsimbi yekhabhoni edityanisiweyo yobude be-arc.
Inkqubo yokwenziwa kweimibhobho edityanisiweyokubandakanya ukudibanisa iziphelo ezibini zomcu wentsimbi okanye ipleyiti ukwenza isakhiwo esifana netyhubhu.Enye yeendlela ezisebenzayo ezisetyenziselwa le nkqubo yi-longitudinal submerged arc welding (LSAW) ubuchule.Imibhobho yentsimbi ye-LSAW ibonwa ngokomelela kwayo, ukuqina, kunye nokuchaneka komda.I-Botop Steel, umenzi ohamba phambili osekelwe e-China, ugxile ekunikezeniImibhobho yentsimbi ye-LSAW, ivelisa ngaphezu kweetoni ezingama-200,000 ngonyaka.Le mibhobho ifumaneka kumabakala ahlukeneyo afana ne-GR.B, X42, X46, X52, X60, X65, kunye ne-X70 – enika uluhlu olubanzi lokukhetha kwizicelo ezahlukeneyo.
IImibhobho yentsimbi ye-LSAWeyenziwe yiBotop Steel isetyenziswa kakhulu kwishishini leoli kunye negesi.Le mibhobho yenzelwe ngokukodwa ukumelana noxinzelelo oluphezulu, indawo ezonakalisayo, kunye nobushushu obugqithisileyo.Ngobukhulu obuvela kwi-355.6 OD ukuya kwi-1500 OD kunye nobukhulu ukusuka kwi-8mm ukuya kwi-80mm, banokuhlangabezana neemfuno ezahlukeneyo.Ukongezelela, i-Botop Steel iqinisekisa ukuthotyelwa ngokungqongqo kwimigangatho yamazwe ngamazwe njenge-ASTM, i-API, kunye ne-DIN ngexesha lenkqubo yokuvelisa.Oku kuqinisekisa umgangatho kunye nokuthembeka kweemveliso zabo, ukunika abathengi uxolo lwengqondo.
Ukuzibophelela kweBotop Steel kumgangatho kubonakaliswa ngakumbi ziziqinisekiso zovavanyo ezithile ezibonelelwe ngemveliso yazo nganye yombhobho wentsimbi ye-LSAW.Konkeimibhobho kunye ityhubhuiimveliso zibonelelwa nge-3.1 izatifikethi zovavanyo oluthile, ngokwe-EN 10204. Esi satifikethi siqinisekisa ukuba iimveliso zihlangabezana nemigangatho efunekayo kunye neenkcukacha, ukunika abathengi isiqinisekiso semveliso ethembekileyo nephezulu.
Ukuququmbela,API 5L PSL1&PSL2 GR.B X42 X46 X52 X60 X65 X70imibhobho yentsimbi ye-longitudinal efakwe kwi-arc edityanisiweyo eyenziwe kusetyenziswa ubuchule be-LSAW inikezela ngesisombululo esithembekileyo kunye nesigxina kwishishini leoli negesi.I-Botop Steel, njengomvelisi othembekileyo kunye nomgcini-mpahla, ibonelela ngeendlela ezininzi zokukhetha ngokwemigangatho, ubungakanani, kunye nobukhulu.Ukuzinikela kwabo kumgangatho kunye nokubambelela kwimigangatho yamazwe ngamazwe kubenza babe ngababoneleli abathandwayo kwiimarike.
