Ityhubhu yentsimbi engenamthungo ye-13CrMo4-5: EN 10216-2, Izicelo, Uvavanyo kunye neSikhokelo sokuThenga

Xa iprojekthi ifuna iityhubhu zentsimbi ezingenamthungoinkonzo yobushushu obuphezulu kunye noxinzelelo oluphezuluUkukhetha izinto akuyonto nje yokukhetha uhlobo lwe-alloy. Abathengi kufuneka baqwalasele umgangatho ofanelekileyo, unyango lobushushu, iimfuno zovavanyo, ubukhulu, amaxwebhu kunye neshedyuli yokuhanjiswa.

Kwizixhobo zoxinzelelo zaseYurophu kunye neeprojekthi zamandla obushushu,Ityhubhu yentsimbi engenamthungo ye-EN 10216-2 13CrMo4-5yenye yeendidi abathengi abanokudibana nazo xa besebenzisa ubushushu obuphezulu. Ngokudibanisa i-chromium kunye ne-molybdenum, olu hlobo lwenzelwe usetyenziso lwenkonzo yoxinzelelo apho ukusebenza koomatshini kubushushu obuphezulu kubalulekile.

Nangona kunjalo, kumaqela okuthenga, umbuzo ophambili awupheleli nje ekubeni"Yintoni i-13CrMo4-5?"kodwa kwakhona"Ingaba ifanelekile kwisicelo sam, yintoni endifanele ndiyichaze, kwaye ndingazifumana njani izinto ezihambelana nemithetho ngexesha elifanelekileyo?"

Yintoni ityhubhu yentsimbi engenamthungo ye-13CrMo4-5?

13CrMo4-5ludidi lwentsimbi ye-chromium-molybdenum alloy oluchazwe kwiEN 10216-2kwiityhubhu ezingenamthungo ezisetyenziselwa iinjongo zoxinzelelo ezineempawu ezithile zobushushu obuphezulu. Inani lazo lezinto ezibonakalayo yi1.7335.

Indibaniselwano ye-chromium kunye ne-molybdenum inika le nto iimpawu ezifanelekileyo kuxinzelelo kunye nenkonzo yobushushu obuphezulu. Ngenxa yoko,Ityhubhu yentsimbi engenamthungo ye-13CrMo4-5ingaqwalaselwa kwizicelo ezifana nezixhobo zamandla obushushu, iibhoyila, iinkqubo zomphunga, izitshintshi zobushushu kunye nezixhobo zoxinzelelo ezikhethiweyo.

Ukufaneleka kwangempela kwezinto kufuneka kuqinisekiswe rhoqo ngokuchasene nobushushu boyilo lweprojekthi, uxinzelelo, ikhowudi yezixhobo kunye neenkcukacha zezinto ezifanelekileyo.

EN 10216-2 13CrMo4-5: Kutheni iMigangatho ibalulekile

Kubathengi,EN 10216-2ingaphezulu nje kokuba yinto ebonakalayo. Ichaza iimfuno zobuchwephesha zokuhambisa izinto ezigubungela iindawo ezifana nokwakheka kweekhemikhali, iimpawu zoomatshini, ubukhulu, uvavanyo kunye nokuhlolwa.

Oku kubaluleke kakhulu xa uthenga iityhubhu zezixhobo zoxinzelelo kuba ikowuteshini ethi "13CrMo4-5" kuphela isenokungabi nolwazi olwaneleyo lokuvelisa nokuhlola.

Inkcazelo efanelekileyo yokuthenga kufuneka ichaze:

● Udidi lwezinto:13CrMo4-5 / 1.7335

● Umgangatho wemveliso:EN 10216-2

● Ububanzi bangaphandle kunye nobukhulu bodonga

● Ubude betyhubhu kunye nobungakanani

● Imeko yokuhanjiswa kunye neemfuno zonyango lobushushu

● Iimfuneko zovavanyo kunye novavanyo olungatshabalalisiyo

● Inqanaba lokuhlola kunye namaxwebhu

● Iimfuno zesatifikethi sezinto ze-EN 10204

● Iimfuneko zokupakisha nokuphawula

Kwiiprojekthi ze-EU, ukuthobela i-PED kufuneka kuhlolwe kwinqanaba lezixhobo kunye novavanyo lokuhambelana endaweni yokuthathwa kuphela kwizinga lentsimbi. IKhomishini yaseYurophu igcina uluhlu lwangoku lwemigangatho ehambelanayo kunye nolwazi oluhambelanayo lwe-PED.

Isetyenziswa phi i-13CrMo4-5?

Ixabiso elisebenzisekayo leItyhubhu yentsimbi ye-alloy ye-13CrMo4-5ivela kuluhlu lwesicelo sayo.

Umgangatho ochanekileyo uxhomekeke kwiimeko zokusebenza ezipheleleyo.I-13CrMo4-5 akufuneki iphathwe njengenokutshintshwa ngokuzenzekelayo nolunye uhlobo lwe-alloy kuba nje ukwakheka kweekhemikhali kubonakala kufana.

13CrMo4-5 ngokuchaseneyoI-ASTM A335 P12 kwayeI-ASTM A213 T12

Iiprojekthi zamazwe ngamazwe ngamanye amaxesha zifuna abathengi ukuba bathelekise iinkcukacha zezinto zaseYurophu neze-ASTM/ASME.

Amanqaku adla ngokuxoxwa ngawo aqukaI-ASTM A335 P12kwipayipi yentsimbi ye-ferritic alloy-steel engenamthungo ephezulu kunyeI-ASTM A213 T12kwiityhubhu zebhoyila, i-superheater kunye ne-heat-exchanger.

Ezi ntlobo ziyinxalenye yosapho olufanayo lwezinto ze-chromium-molybdenum, kodwa zinjaloayiqondisi ngokuzenzekelayo izinto ezifanayo of I-EN 10216-2 13CrMo4-5.

Ukuze kuthengwe ezinye izinto ezintsha okanye ezisemgangathweni, abathengi kufuneka bathelekise oku kulandelayo:

● Ukwakheka kweekhemikhali

● Iipropati zoomatshini zobushushu begumbi

● Iipropati zobushushu obuphezulu

● Iimfuneko zonyango lobushushu

● Iimfuneko zempembelelo

● Ukunyamezelana kobukhulu

● Iimfuneko ze-NDE

● Ifomu yemveliso kunye nesicelo esicetywayo

● Ikhowudi yoyilo esebenzayo kunye nokuvunywa kweprojekthi

Olu thelekiso lubaluleke kakhulu xa umntu osebenza kwi-EPC ezama ukuhlanganisa ukuthengwa kwempahla ngokwemigangatho yaseYurophu, yaseMelika neyaseAsia.

Ukuveliswa kweetyhubhu zentsimbi ezingenamthungo ze-13CrMo4-5

Kwiityhubhu zenkonzo yoxinzelelo, umgangatho wokuvelisa unxulumene kakhulu nokuzinza kwemveliso yokugqibela.

Indlela eqhelekileyo yemveliso ingabandakanya:

Ukwenza ngentsimbi → Ukulungiselela iibhilethi → Ukufudumeza → Ukubhoboza → Ukuqengqeleka okushushu okanye ukuzoba okubandayo → Unyango lobushushu → Ukulula → Ukusika → Ukuhlola → Ukumakisha nokupakisha

Ngexesha lemveliso, ulawulo oluphambili luquka ukwakheka kweekhemikhali, umgangatho we-billet, ukuchaneka kobukhulu, unyango lobushushu kunye nokuhlolwa kokugqibela.

Ngokuxhomekeke kubungakanani obufunekayo kunye neenkcukacha,iityhubhu ezingenamthungo ezigqityiweyo okanye ezigqityiweyo ezibandayoingaqwalaselwa. Umzobo obandayo unokubonelela ngolawulo oluqinileyo lobukhulu, ngelixa iityhubhu ezigqityiweyo zisetyenziswa kakhulu kwiimilinganiselo ezinkulu.

Indlela yokugqibela yokuvelisa kufuneka ikhethwe ngokwedayamitha efunekayo, ubukhulu bodonga, ukunyamezela kunye neenkcukacha zeprojekthi endaweni yokukhetha nje indlela yokuvelisa enexabiso eliphantsi.

Iimfuno zovavanyo kunye nokuhlolwa

Kubathengi beUmbhobho wentsimbi engenamthungo we-13CrMo4-5, amaxwebhu kunye nokuhlolwa kudla ngokubaluleka njengezinto ezisetyenzisiweyo.

Ngokuxhomekeke kwi-odolo yokuthenga kunye nomgangatho ofanelekileyo, ukuhlolwa kungabandakanya:

● Uhlalutyo lokwakheka kweekhemikhali

● Uvavanyo lokuxinana

● Uvavanyo lwempembelelo apho kuchaziwe khona

● Uvavanyo lokuqina apho kuyimfuneko

● Uvavanyo lokuqina kwamanzi okanye ukuvuza

● Uvavanyo lwe-ultrasonic okanye olunye uvavanyo olungatshabalalisiyo

● Ukuhlolwa kobukhulu

● Ukuhlolwa okubonakalayo nokuphezulu

● Iirekhodi zonyango lobushushu

● Ukuchongwa kunye nokulandeleka kwezinto

● Uxwebhu lokuhlola lwe-EN 10204

Kwiiprojekthi ezibalulekileyo, abathengi banokufuna uhlolo lomntu wesithathu, i-NDE eyongezelelweyo, i-PMI, uvavanyo olukhethekileyo okanye izicwangciso zovavanyo ezithile.

Ke ngoko, abathengi kufuneka bachaze umda wokuhlolwangaphambi kwemveliso, endaweni yokongeza iimfuno ezikhethekileyo emva kokuba iityhubhu zenziwe.

Yintoni Abathengi Abafanele Bayihlole Ngaphambi Kokuba Bayi-odole?

Ingxaki eqhelekileyo yokuthenga kukuba isicelo siquka kuphela:

"Ipayipi engenamthungo ye-13CrMo4-5, nceda ucaphule."

Oku akwanele ukuba kubekho isicatshulwa esichanekileyo.

Ukuze ufumane ulwazi olukhawulezayo noluthembekileyo, bonelela:

1. Umgangatho kunye nomgangatho — EN 10216-2 / 13CrMo4-5

2. Ubukhulu — OD × WT okanye DN/NPS × ishedyuli apho kufanelekileyo

3. Ubude — ubude obuzinzileyo, ubude obungacwangciswanga okanye imfuneko ethile yeprojekthi

4. Ubungakanani — iziqwenga, iimitha okanye iitoni

5. Isicelo — ibhoyila, umgca womphunga, isixhobo sokutshintsha ubushushu, izixhobo zoxinzelelo, njl.

9. Iimfuneko zokupakisha kunye nokumakisha

10.Naluphi na ulwazi lobuchwephesha oluhambelana neprojekthi ethile

Ukubonelela ngolu lwazi kuvumela umthengisi ukuba ajonge kungekuphela nje ixabiso, kodwa kunyeukufumaneka kwezinto, ukuba kunokwenzeka ukuvelisa, iimfuno zokuhlolwa kunye nomngcipheko wokuhanjiswa.

Imveliso yesitokhwe okanye entsha: Yeyiphi engcono?

Kwiisayizi eziqhelekileyo, isitokhwe esikhoyo sinokunciphisa kakhulu umjikelo wokuthengwa.

Nangona kunjalo,Ityhubhu yentsimbi engenamthungo ye-13CrMo4-5Iiprojekthi zihlala ziquka ubukhulu obungaqhelekanga, ubukhulu bodonga oluthile, uvavanyo olukhethekileyo okanye amaxwebhu eprojekthi. Kwezi meko, imveliso entsha inokuba yeyona ifanelekileyo.

I-SANONPIPE inokuvavanya zombini ezi ndlela:

Isitokhwe esifumanekayo
Ifanelekile xa umgangatho kunye nobukhulu obufunekayo sele bukhona kwaye ishedyuli yeprojekthi incinci.

Imveliso entsha
Ifanelekile kwiindleko ezinkulu, ubukhulu obukhethekileyo, ukunyamezelana okuthile okanye iimfuno ezongezelelweyo zokuhlolwa.

Le ndlela yokuvelisa isitokhwe kunye nemveliso ivumela abathengi ukuba balinganiseleixabiso, ukuthobela imithetho kunye nexesha lokuhambisaendaweni yokugxila kwixabiso leyunithi kuphela.
