Indlela yokufunda iSatifikethi soVavanyo lweSitshingi seNsimbi esiNgenasici (i-MTC)

Intshayelelo

Ukuze bafunde isatifikethi sovavanyo lwe-stainless steel mill (MTC), abathengi kufuneka baqinisekise umgangatho wezinto, umgangatho we-stainless steel, inombolo yobushushu, ukwakheka kweekhemikhali, iimpawu zoomatshini, imeko yokuhanjiswa, iziphumo zovavanyo, uhlobo lwesatifikethi kunye nolwazi lokulandeleka. Kwimpahla yobunjineli, i-MTC ayiloxwebhu lomgangatho kuphela; bubungqina bobuchwephesha bokuba izinto ze-stainless steel ezibonelelweyo zihambelana ne-ASTM, ASME, EN, DIN, JIS okanye GB efunekayo kwaye zinokulandelelwa emva kobushushu bokuqala bokunyibilika.

Kwimivalo yentsimbi engagqwaliyo, iipayipi, iityhubhu, iipleyiti, amashiti, iingcingo, iintambo zocingo, iiflange kunye neemveliso ezenziwe ngesinyithi, i-MTC yenye yamaxwebhu abaluleke kakhulu ahlolwayo ngaphambi kokuthunyelwa, ukufakwa okanye ukwamkelwa kweprojekthi. I-EN 10204 3.1 MTC echanekileyo inceda abathengi ukuba baqinisekise ubunyani benqanaba, ukuthobela iikhemikhali, amandla oomatshini, ukumelana nokugqwala, umgangatho wobukhulu, ulawulo lwenombolo yobushushu kunye neerekhodi zokuhlola ezifana novavanyo lwe-PMI, uvavanyo lwe-UT okanye ukuhlolwa komntu wesithathu xa kufuneka.

KwaSaky Steel, uphononongo lweMTC luyinxalenye yenkqubo yethu yokulandelela izinto kunye nenkqubo yokulawula izinto ezingezizo zokwenyani. Nokuba umthengi uthenga umbhobho wentsimbi engagqwali engama-304, ibha ejikelezileyo yentsimbi engagqwali engama-316L, ipleyiti yentsimbi engagqwali engama-321, ityhubhu yentsimbi engagqwali engama-2205 okanye iimveliso zentsimbi engagqwali ezingama-904L, isatifikethi kufuneka sijongwe ngononophelo malunga nomyalelo wokuthenga, umgangatho ofanelekileyo kunye neenkcukacha zeprojekthi.

Yintoni iSatifikethi soVavanyo lweSigayo seNsimbi Engagqwaliyo?

Isatifikethi sovavanyo lwe-stainless steel mill, esikwabizwa ngokuba yi-MTC, MTR, isatifikethi se-mill okanye isitifiketi sezinto, luxwebhu olusemthethweni lomgangatho olukhutshwa ngumvelisi okanye ngumthengisi ogunyazisiweyo. Sirekhoda iziphumo zovavanyo zokwenyani zebhetshi ethile yezinto ze-stainless steel kwaye siqinisekisa ukuba izinto ziyahambelana nomgangatho ochaziweyo.

Isatifikethi esiceliweyo kakhulu sokuthengwa kwentsimbi engagqwaliyo yemizi-mveliso yi-EN 10204 3.1. Esi satifikethi sikhutshwa ngummeli wokuhlola ogunyazisiweyo womenzi kwaye siqinisekisa ukuba izinto ezibonelelweyo zivavanyiwe ngokweemfuno ze-odolo. Kwezinye iiprojekthi ezibalulekileyo, abathengi banokucela isatifikethi se-EN 10204 3.2 kwi-arhente yohlolo yomntu wesithathu ezimeleyo okanye umbutho wokwahlukanisa.

Iimpazamo zomthengi eziqhelekileyo xa ufunda i-MTC

Iingxabano ezininzi zomgangatho ekuthengweni kwentsimbi engagqwaliyo zibangelwa kukuhlolwa kwesatifikethi okungaphelelanga. Abathengi banokujonga igama lomgangatho kodwa bangawunaki umgangatho, uhlobo lwemveliso, inombolo yobushushu okanye amaxabiso angempela eekhemikhali. Uphononongo lobuchwephesha lwe-MTC kufuneka lube lucwangcisiweyo, ngakumbi kwii-odolo zokuthumela ngaphandle kunye neeprojekthi zobunjineli.

Impazamo 1: Ukujonga igama leBanga kuphela

Igama lebanga lodwa alanelanga. Isatifikethi esithi “316L” kufuneka siquke ulwazi lwebanga elilinganayo le-UNS S31603, umgangatho ofanelekileyo, inombolo yobushushu kunye nokwakheka kweekhemikhali zokwenyani. Abathengi kufuneka banikele ingqalelo ekhethekileyo kumxholo we-Mo kunye nomxholo wekhabhoni kwintsimbi engagqwaliyo ye-316L.

Impazamo yesi-2: Ukungayinaki iMigangatho yeFomu yeMveliso

Ibha yentsimbi engagqwaliyo, umbhobho, ipleyiti, ucingo kunye neflange zinokusebenzisa imigangatho eyahlukileyo nokuba umgangatho ufana. Umzekelo, i-ASTM A276 ayifani ne-ASTM A312. Abathengi kufuneka bajonge ukuba ingaba umda oqhelekileyo uyahambelana na nemveliso e-odolweyo.

Impazamo 3: Ayifanisi Inombolo yoBushushu kunye nokuMakisha kwezinto

Ukuba inombolo yobushushu kwi-MTC ayifani nezinto ezibonakalayo, ukulandeleka kuyaphuka. Oku kunokubangela ukwaliwa kweprojekthi nokuba izinto ngokwazo zibonakala zichanekile. Ulawulo lwenombolo yobushushu kufuneka luqinisekiswe ngaphambi kokuthunyelwa kwaye kwakhona ngexesha lokuhlolwa.

Impazamo 4: Ukwamkela Izatifikethi Ngaphandle KweeMpawu zoVavanyo zokwenyani

I-MTC efanelekileyo kufuneka ibonise iziphumo zovavanyo zokwenyani, kungekuphela nje iingxelo eziqhelekileyo. Ulwakhiwo lweekhemikhali kunye neempawu zoomatshini kufuneka zirekhodwe ngamanani. Kwiiprojekthi ezibalulekileyo, abathengi kufuneka bacele uvavanyo lwe-PMI, uvavanyo lwe-UT okanye iingxelo zokuhlolwa komntu wesithathu njengenkxaso eyongezelelweyo.

I-EN 10204 3.1 luhlobo lwesatifikethi sokuhlola esiqhelekileyo esisetyenziswa ekunikezelweni kwezinto zesinyithi. Iqinisekisa ukuba izinto ezihanjisiweyo zivavanyiwe ngokweemfuno ezithile kwaye isatifikethi sikhutshwa ngummeli wokuhlola ogunyazisiweyo womenzi.

Ndingajonga njani ukuba i-MTC yentsimbi engagqwaliyo ithembekile?

Jonga igama lomthengisi, ulwazi lomenzi, ibakala, umgangatho, inombolo yobushushu, ulwakhiwo lweekhemikhali, iimpawu zoomatshini, umhla wesatifikethi, utyikityo lokuhlolwa kunye nokuhambelana nophawu lwezinto ezibonakalayo. Kwizinto ezixabisekileyo okanye ezibalulekileyo, cela uvavanyo lwe-PMI okanye uhlolo lomntu wesithathu.

Kutheni uvavanyo lwe-PMI lubalulekile?

Uvavanyo lwe-PMI lunceda ukuqinisekisa izinto ze-alloy zokwenyani zezinto zentsimbi engagqwali. Iluncedo ngokukodwa ekuchongeni i-316L, 904L, intsimbi engagqwali ephindwe kabini kunye nezinye iiklasi ze-alloyed apho i-Cr, i-Ni, i-Mo okanye ezinye izinto zichaphazela ngqo ukusebenza.

Ngaba i-MTC kufuneka ihlolwe ngaphambi kokuba ithunyelwe?

Ewe. Abathengi kufuneka bahlole i-MTC ngaphambi kokuba ithunyelwe nanini na xa kunokwenzeka. Uhlolo lwakwangoko lunceda ekuphepheni ukuhanjiswa okungalunganga, ukungabikho kwezinto zokuhlolwa, iireferensi ezisemgangathweni ezingachanekanga okanye iingxaki zoxwebhu ngexesha lokususwa kwempahla kunye nokwamkelwa kweprojekthi.

Isiphelo

Ukufunda indlela yokufunda isatifikethi sovavanyo lwe-stainless steel mill kubalulekile kubathengi, iinjineli, abahloli kunye namaqela okuthenga iiprojekthi. Uphononongo lwe-MTC yobungcali kufuneka lugubungele ububanzi obuqhelekileyo, ukuchongwa kwamanqanaba, ukwakheka kweekhemikhali, iimpawu zoomatshini, ukulandeleka kwenani lobushushu, iirekhodi zokuhlola kunye nokunyaniseka kwesatifikethi.

Kwizinto zentsimbi engagqwaliyo ezisetyenziswa kwizixhobo zokucubungula iikhemikhali, iinkqubo zepetrochemical, izakhiwo zaselwandle, oomatshini bokutya, izixhobo zoxinzelelo, izinto zikaloliwe kunye nokwenziwa kwemizi-mveliso, i-MTC yinxalenye ebalulekileyo yokuqinisekisa umgangatho. Ngokujonga isatifikethi ngononophelo ngaphambi kokuthunyelwa, abathengi banokunciphisa iingozi zezinto eziphathekayo, baphephe ukulibaziseka kweprojekthi kwaye baphucule ukuthembeka kokunikezelwa kwexesha elide.
