Ukubaluleka kokunamathela kwinkcazo echanekileyo yombhobho we-carbon steel kwizicelo zoshishino ayikwazi ukugqithiswa. Ezi nkcukacha ziqinisekisa ukuba izinto ezisetyenziselwa ukwakhiwa kunye neenkqubo zokuvelisa zihlangabezana nemigangatho efunekayo yokhuseleko, ukuqina kunye nokusebenza. Phakathi kweentlobo ezahlukeneyo zemibhobho, imibhobho ye-carbon steel engenamthungo igqamile, ngokukodwa kwizicelo eziphezulu zokushisa.
Enye yenkcazo igubungela umbhobho we-carbon steel ongenamthungo ukusuka kwi-NPS 1 ukuya kwi-NPS 48 kunye nobukhulu bodonga oluqhelekileyo ngokuhambelana nomgangatho we-ASME B 36.10M. Le ngcaciso ibaluleke kakhulu kumashishini afuna imibhobho enokumelana neemeko ezinzima, ezifana neoli kunye negesi, ukuveliswa kwamandla, kunye nokulungiswa kweekhemikhali. Ikhono lale mibhobho ukumelana nokushisa okuphezulu ngelixa ukugcina ukunyaniseka kwesakhiwo kubalulekile kukhuseleko kunye nokusebenza kakuhle kwemisebenzi yoshishino.
Ubume obungenamthungo kweziumbhobho wentsimbi yekhabhoniinikeza inani leenzuzo. Ngokungafani nemibhobho edibeneyo, iipayipi ezingenamthungo zenziwe kwintsimbi enye, ukuphelisa umngcipheko wamanqaku abuthathaka anokuthi avele kwi-weld seam. Le propati ibenza bafaneleke ngokukodwa ukugoba, ukugoba kunye nokusebenza okufanayo kokubumba, kunye ne-welding. Imibhobho yentsimbi yekhabhoni engenamthungo iyaguquguquka kwaye ingasetyenziswa kwizicelo ezahlukeneyo, ukusuka ekugqithisweni kwamanzi ukuya kwinkxaso yesakhiwo koomatshini abanzima.
Embindini weshishini yinkampani eseCangzhou, kwiPhondo laseHebei, ebiyinkokeli yoshishino ukusukela ekusekweni kwayo ngo-1993. Le nkampani ithatha indawo ye-350,000 square metres, ine-asethi epheleleyo ye-RMB 680 yezigidi kwaye iqeshe malunga nabasebenzi abanobuchule abangama-680. Isiseko esomeleleyo kunye nabasebenzi abomeleleyo benza ukuba inkampani ivelise imibhobho yentsimbi yekhabhoni ekumgangatho ophezulu ekuchazeni ngokucacileyo, ukuqinisekisa ukuba abathengi bafumana iimveliso ezithembekileyo ezihlangabezana neemfuno zabo zoshishino.
Ukubaluleka kweishedyuli carbon steel umbhobhoidlula ngaphaya kokuthotyelwa kokuqinisekisa ukuphila ixesha elide kunye nokuthembeka kweenkqubo zoshishino. Xa amashishini enza utyalo-mali kwizinto ezikumgangatho ophezulu ezihlangabezana neenkcukacha ezimiselweyo, awagcini nje ngokukhusela ukusebenza kodwa aphucula imveliso iyonke. Iinkcazo ezifanelekileyo zinokunciphisa iindleko zokulondoloza, ukunciphisa ukuphazamiseka komsebenzi, kunye nokuphucula ukhuseleko lwabasebenzi.
Ngaphaya koko, njengoko amashishini eguquka kwaye kuvela imiceli mngeni emitsha, imfuno yezixhobo eziphambili iyakhula. Imibhobho ye-carbon steel engenamthungo eveliswa yinkampani yaseCangzhou-based yenzelwe ukuhlangabezana nezi mfuno eziguqukayo, ukubonelela ngezisombululo ezintsha nezithembekileyo. Ngokuthobela ngokungqongqo umgangatho we-ASME B 36.10M, inkampani iqinisekisa ukuba iimveliso zayo zifanelekile kuluhlu olubanzi lwezicelo, kubandakanywa nezo zifuna inkonzo yokushisa okuphezulu.
Isishwankathelo, ukubaluleka kwenkcazo yepayipi yensimbi ye-carbon kwizicelo zoshishino ayikwazi ukuhoywa. Akunjalo kuphela ezi nkcukacha ziqinisekisa umgangatho kunye nokusebenza kombhobho, kodwa zidlala indima ebalulekileyo ekukhuseleni nasekusebenzeni kakuhle kwemisebenzi yoshishino. Ngesiseko esomeleleyo sokuvelisa kunye nokuzibophelela kumgangatho, inkampani esekwe eCangzhou iya kuqhubeka nokukhokela ekuboneleleni ngemibhobho yentsimbi yekhabhoni engenamthungo ehlangabezana neemfuno ezingqongqo zeshishini. Njengoko ishishini liqhubeka likhula kwaye likhula, izixhobo ezikumgangatho ophezulu ziya kuqhubeka zidlala indima ebalulekileyo ekuqhubeni izinto ezintsha kunye nempumelelo.
