Kutheni Ukhetha Umthengisi Oqeqeshiweyo Endaweni Yexabiso Eliphantsi Kuphela?

Ixabiso eliphantsi lingabonakala linomtsalane, kodwa iibha ezingqukuva zentsimbi engagqwaliyo zizinto zobunjineli, azizo izinto eziqhelekileyo. Umthengisi oqeqeshiweyo unceda abathengi ukunciphisa umngcipheko weprojekthi ngokuqinisekisa izixhobo ezichanekileyo, umgangatho, umphezulu, ukunyamezela, ukuhlolwa kunye namaxwebhu ngaphambi kokuba athunyelwe.

Umzekelo, i-304 kunye ne-316L zinokubonakala zifana, kodwa umxholo wazo we-molybdenum kunye nokumelana nokugqwala kwe-chloride zahlukile. I-2205 duplex stainless steel ifuna unyango oluchanekileyo lwesisombululo kunye nokulinganisela kwesigaba. I-17-4PH ifuna iimeko ezicacileyo zonyango lobushushu ezifana ne-H900, H1025 okanye i-H1150. Ngaphandle kolawulo olufanelekileyo lwezinto, umthengi unokufumana iibha ezinzima ukuzisebenzisa ngomatshini, ezingaphumeleliyo ekuhlolweni okanye ezingahlangabezani neemfuno zeprojekthi.

Xa ukhetha umthengisi weebha ezijikelezileyo zentsimbi engagqwaliyo eTshayina, khangela iqabane elinokubonelela ngonxibelelwano lobuchwephesha, ukulandeleka kwezinto, ixesha elifanelekileyo lokukhokela, ukupakisha kwamanye amazwe kunye nenkxaso yamaxwebhu emva kokuthengisa. Oku kubaluleke kakhulu kubathengi kumashishini aselwandle, amakhemikhali, izixhobo zoxinzelelo, oomatshini, okwakha kunye namandla.

Imibuzo Ebuzwa Rhoqo: Ukukhetha Umthengisi weBhari yeNtsimbi Engagqwaliyo eTshayina

Loluphi ulwazi endifanele ndiluthumele xa ndicela ikowuteshini yebha ejikelezileyo yentsimbi engagqwaliyo?

Nceda unikezele ngebanga, umgangatho, ububanzi, ubude, ubungakanani, ukugqitywa komphezulu, ukunyamezela, iimfuno zovavanyo, iimfuno zesatifikethi, izibuko lendawo oya kuyo kunye nemigaqo yorhwebo oyithandayo. Ukuba unemifanekiso okanye iinkcukacha zeprojekthi, zithumele kunye ne-RFQ.

Ngaba umthengisi waseTshayina angabonelela nge-EN 10204 3.1 MTC?

Ewe. Umthengisi weebha ezijikelezileyo zentsimbi engagqwaliyo unokubonelela nge-EN 10204 3.1 MTC ebonisa inani lobushushu, ukwakheka kweekhemikhali, iimpawu zoomatshini kunye nomgangatho ofanelekileyo. Abathengi kufuneka bajonge ukuba inombolo yobushushu kwi-MTC iyahambelana nelebheli yezinto.

Ngaba uvavanyo lwe-PMI luyimfuneko kwiibha ezijikelezileyo zentsimbi engagqwaliyo?

Uvavanyo lwe-PMI luyacetyiswa kakhulu kwiindidi ezibalulekileyo ze-alloy kunye nee-odolo zeprojekthi, ingakumbi xa umthengi efuna ulawulo lwezinto ezichasene nobuxoki. I-PMI inokunceda ukuqinisekisa izinto eziphambili ze-alloy kunye nokunciphisa umngcipheko wokudibana kwendidi.

Yintoni umahluko phakathi kwebha egoqwe ngobushushu kunye nebha ekhanyayo?

Iibhari ezigoqiweyo ezishushu zihlala zinomphezulu omnyama okanye orhabaxa kwaye zingabizi kakhulu. Iibhari ezikhanyayo ziyatsalwa kubanda, zixotyulwe okanye zigaywe ukuze kugqitywe umphezulu ngcono, kunyamezelwe ubukhulu kunye nokuthe tye. Ukhetho oluchanekileyo luxhomekeke kwimvume yomatshini kunye nokusetyenziswa kokugqibela.

Kudla ngokuthatha ixesha elingakanani ukuhanjiswa?

Ubungakanani besitokhwe bunokulungiswa kwiintsuku ezisi-7 ukuya kwezili-15 emva kokuqinisekiswa kweodolo. Imveliso eyenzelwe wena, iibhari ezinkulu ezibunjiweyo, ukugqitywa komphezulu okhethekileyo okanye ukuhlolwa komntu wesithathu kunokufuna iintsuku ezingama-20 ukuya kwezingama-60 kuxhomekeke kwinkcazo kunye nobungakanani beodolo.

Isiphelo

Ukuze ukhethe umthengisi webha ejikelezileyo yentsimbi engagqwaliyo eTshayina, amaqela okuthenga kufuneka ahlole ixabiso elingaphezulu kweleyunithi. Umthengisi ochanekileyo kufuneka aqonde amanqanaba entsimbi engagqwaliyo, imigangatho yamazwe ngamazwe, iimfuno zomatshini, iindlela zokuvavanya, ukulandeleka kwenani lobushushu, i-EN 10204 3.1 MTC, uvavanyo lwe-PMI, uvavanyo lwe-UT, ukupakisha kwamanye amazwe kunye neeshedyuli zokuhambisa.

Kwiiprojekthi zoshishino, ukubonelela ngezinto ezithembekileyo kuthetha ukuba iingxaki zokuhlola azikho, umngcipheko wokuthunyelwa uncinci kwaye ukusebenza ngcono kwexesha elide kuya kuba ngcono. Nokuba ufuna ibha ejikelezileyo engama-304 yomatshini wokulungisa izinto, ibha ye-316L yokusetyenziswa elwandle, ibha ye-duplex engama-2205 yenkonzo ye-chloride okanye ibha ye-17-4PH yezixhobo ezinamandla aphezulu, ukukhetha umthengisi onamava linyathelo lokuqala lokufumana izinto ezizinzileyo.
