Xa uthengaUmbhobho wentsimbi yekhabhoni engenamthungo we-ASTM A106, omnye wemibuzo eqhelekileyo ngulo:Yintoni umahluko phakathi kwe-ASTM A106 Grade B kunye neGrade C?Zombini ezi zigaba zenzelwe inkonzo yobushushu obuphezulu, kodwa zahlukile ngamandla amancinci oomatshini kunye nomxholo ophezulu wekhabhoni. Ukukhetha umgangatho ochanekileyo kubalulekile ekuthobeleni iprojekthi, ukwenziwa, ukuwelda kunye nokuthembeka kwemibhobho ixesha elide.
Kubathengi abasebenza ngokuvelisa umbane, ioyile negesi, iindawo zokucoca kunye nemibhobho yemizi-mveliso, ukuqonda la mahluko kunceda ukuthintela ukungalingani kwezinto, iindleko ezingeyomfuneko kunye nokulibaziseka kokuhanjiswa.
1. Yintoni i-ASTM A106 Grade B kunye neGrade C?
I-ASTM A106/A106Mizigqubutheloumbhobho wentsimbi yekhabhoni ongenamthungo wenkonzo yobushushu obuphezulu. Le nkcazelo ibandakanya amaBakala A, B kunye no-C. IBakala B lisetyenziswa kakhulu kwiipayipi zemizi-mveliso, ngelixa iBakala C libonelela ngamandla aphezulu okutsalwa kunye nokukhupha.
ZombiniUmbhobho ongenamthungo we-ASTM A106 Gr BkwayeUmbhobho ongenamthungo we-ASTM A106 Gr Cingaqwalaselwa kwizicelo ezifanelekileyo zokufaka imibhobho enobushushu obuphezulu. Nangona kunjalo, umgangatho kufuneka uhlangabezane nekhowudi yoyilo, iimeko zokusebenza kunye neenkcukacha zezinto zeprojekthi.
2. I-ASTM A106 Ibanga B vs Ibanga C: Umahluko oPhambili
Le theyibhile ilandelayo ishwankathela umahluko ophambili oqhele ukucaciswa kwi-ASTM A106 Grade B kunye neGrade C. Soloko uqinisekisa uhlelo olufanelekileyo lomgangatho kunye neenkcukacha zokuthenga ngaphambi kokuba u-odole.
| Ipropati | I-ASTM A106 Ibanga B | I-ASTM A106 Ibanga C |
|---|---|---|
| Uhlobo lwemveliso | Umbhobho wentsimbi yekhabhoni ongenamthungo | Umbhobho wentsimbi yekhabhoni ongenamthungo |
| Amandla amancinci okuxinana | I-415 MPa (60,000 psi) | I-485 MPa (70,000 psi) |
| Amandla amancinci okuvelisa | 240 MPa (35,000 psi) | 275 MPa (40,000 psi) |
| Umxholo ophezulu wekhabhoni | 0.30% | 0.35% |
| Ingqwalasela eqhelekileyo yokuthenga | Ibanga eliqhelekileyo lokubhobhoza kwemizi-mveliso | Amandla aphantsi aphezulu achazwe phezulu |
| Into yokukhetha isitshixo | Iimfuno zoyilo kunye nenkonzo | Iimfuno zoyilo kunye nenkonzo |
Umahluko ophambili ucacile:I-ASTM A106 Grade C inamandla aphezulu okutsalwa kunye nokukhupha amandla kuneGrade BUmxholo wayo ophezulu wekhabhoni ovumelekileyo nawo uphezulu. Olu mahluko lunokuchaphazela iinkqubo zokwenza kunye nokuwelda, ngoko ke iBakala C akufuneki lithathwe njengento elula yokutshintsha iBakala B.
3. Ngaba i-ASTM A106 Grade C ingcono kuneGrade B?
Akunjalo ngokuyimfuneko. Ukufuna amandla aphezulu akuthethi ukuba ngokuzenzekelayo kuza kubakho ukhetho olungcono kuyo yonke iprojekthi.
I-ASTM A106 Ibanga BIqhele ukumiselwa kwiintambo zomphunga, iipayipi zokucoca, iipayipi zezityalo zamandla kunye nezinye iinkonzo zoshishino apho umgangatho uhlangabezana neemfuno zoyilo ezifanelekileyo. Abathengi badla ngokuyijonga ngenxa yokusetyenziswa kwayo okuqhelekileyo kunye nokwaziwa kwayo ngokubanzi kwimarike.
I-ASTM A106 Ibanga Cinokuba yinto efanelekileyo xa iinkcukacha zobunjineli zifuna amandla ayo aphezulu. Nangona kunjalo, abathengi kufuneka baqinisekise uxinzelelo oluvumelekileyo kubushushu boyilo, ubukhulu bodonga, iimfuno zokwenza kunye nekhowudi yemibhobho efanelekileyo ngaphambi kokutshintsha.
Umbuzo ochanekileyo awungowokuba “Leliphi ibakala elinamandla?” kodwa ngulowo uthi “Leliphi ibakala elinamandla?”"Ngowuphi umgangatho ohambelana neemfuno zoyilo kunye nokuthengwa kweprojekthi?"
4. Izinto ekufuneka ziqwalaselwe malunga nokwakheka kweekhemikhali kunye nokuwelda
Umxholo wekhabhoni ophezulu ngumahluko obalulekileyo phakathi kwala manqanaba mabini:
- Ibanga B:umxholo ophezulu wekhabhoni we-0.30%.
- Ibanga C:umxholo ophezulu wekhabhoni we-0.35%.
Umxholo wekhabhoni unokuphembelela amandla, ukuqina kunye nokudityaniswa. Ngokwenyani, ukwakheka kweekhemikhali zokwenyani, ubungakanani bemibhobho, inkqubo yokudityaniswa kunye neemeko zenkonzo zonke zibalulekile.
Kwiiprojekthi ezibandakanyaUmbhobho wentsimbi engenamthungo we-ASTM A106 Grade C, abathengi kufuneka baqinisekise ukuba inkqubo yokuwelda kunye nolawulo lokwenziwa zifanelekile kwizixhobo ezibonelelweyo. Musa ukucinga ukuba inkqubo yokuwelda ekhoyo yeBanga B isebenza ngokuzenzekelayo kwiBanga C ngaphandle kophononongo lobunjineli olufunekayo.
Ukukhethwa kwezinto kufuneka kuqwalaselwe neemfuno zonyango lobushushu lweprojekthi, ububanzi bokuhlolwa kunye nemigangatho yokwamkelwa efanelekileyo.
5. Izicelo: Zisetyenziswa phi iiBanga B kunye neBanga C?
Zombini ezi ntlobo zinxulunyaniswa nemibhobho yentsimbi yekhabhoni engenamthungo eshushu kakhulu, kodwa ukufaneleka kwayo kuxhomekeke kuyilo lobunjineli.
Umbhobho we-ASTM A106 weBanga Biqhele ukuqwalaselwa ngenxa yezi:
- Ukucoca ioyile kunye nemibhobho yenkqubo ye-petrochemical
- Isikhululo samandla kunye nemibhobho yomphunga
- Ukuthuthwa kolwelo lwemizi-mveliso kumaqondo obushushu aphezulu
- Iipayipi zoxinzelelo oluphezulu apho uyilo luvumela iBanga B
Umbhobho we-ASTM A106 Grade Cingaqwalaselwa apho iinkcukacha zeprojekthi zifuna amandla ayo aphantsi oomatshini kwaye uvavanyo olupheleleyo loyilo luqinisekisa ukufaneleka.
Akukho nqanaba lifanele likhethwe ngokusekelwe kuxinzelelo okanye kubushushu bodwa. Ububanzi bombhobho ongaphandle, ubukhulu bodonga, uxinzelelo loyilo, imvume yokugqwala, iimeko zokusebenza kunye nekhowudi efanelekileyo kufuneka zivavanywe kunye.
6. Yintoni ekufuneka abathengi bayijonge phambi kokuba ba-odole i-ASTM A106 Pipe?
Ixabiso lokhuphiswano libalulekile, kodwa ukuthobela izinto eziphathekayo kunye nokuthembeka kokuhanjiswa kwempahla kubaluleke ngokulinganayo. Ngaphambi kokuba ufake iodolo, qinisekisa oku kulandelayo:
1. Umgangatho kunye nomgangatho
Cacisa i-ASTM A106/A106M kunye nomgangatho ofunekayo ngokucacileyo. Ukuba iprojekthi ifuna i-ASME SA-106, qinisekisa iinkcukacha ezichanekileyo ezilawulayo kunye nohlelo.
2. Ubukhulu kunye nobungakanani
Nika ububanzi bangaphandle okanye i-NPS, ubukhulu bodonga okanye ishedyuli, ubude, ubungakanani kunye nokulungiselela ukuphela.
3. Isatifikethi sovavanyo lwezinto (i-MTC)
Qinisekisa ukuba isatifikethi sichaza umgangatho ochanekileyo kunye nomgangatho, kwaye ukuba ulwakhiwo lweekhemikhali oluchaziweyo kunye neziphumo zovavanyo loomatshini ziyahambelana neemfuno ezifanelekileyo. Qinisekisa ukuba inani lobushushu liyalandeleka.
4. Ukuhlolwa novavanyo
Qinisekisa amalungiselelo ovavanyo olungenakonakala okanye olungenakuguqulwa olufunekayo, iimvavanyo ezongezelelweyo kunye neemfuno zokuhlolwa ngumntu wesithathu kwi-odolo yokuthenga.
5. Ukuhanjiswa kunye namaxwebhu
Qinisekisa ukuba isitokhwe sikhona okanye ixesha lokuhanjiswa kwemveliso, ukumakishwa, ukupakisha, ukuthumela amaxwebhu kunye nendawo yokuhanjiswa ngaphambi kokuba ugqibezele iodolo.
Olu vavanyo lunceda ekunciphiseni umngcipheko wokufumana amanqaku angalunganga, ukufumanisa izikhewu kumaxwebhu ngexesha lokuhlolwa okanye ukulibaziseka ngaphambi kokuthunyelwa.
7. Umthombo we-ASTM A106 Grade B kunye neGrade C yeSteel engenamthungo evela kwi-SANONPIPE
