Izindinganiso ze-ASTM zepayipi lensimbi yekhabhoni
I-American Society for Testing and Materials (ASTM) ithuthukise amazinga ahlukahlukene amapayipi ensimbi yekhabhoni, achaza ngokuningiliziwe usayizi, ukuma, ukwakheka kwamakhemikhali, izakhiwo zemishini kanye nezinye izidingo zobuchwepheshe zamapayipi ensimbi. Okulandelayo yizindinganiso eziningana ezivamile ze-ASTM zamapayipi ensimbi yekhabhoni:
1. Amapayipi Ensimbi Yekhabhoni Angenamthungo
I-ASTM A53: Isebenza ku-welded futhi ingenamthungo emnyama kanyeamapayipi ensimbi acwebezelayo ashisayo, esetshenziswa kabanzi ngezinjongo zesakhiwo, izinhlelo zamapayipi, njll. Le nqubo ihlukaniswe ngamagreyidi amathathu: A, B, kanye no-C ngokuya ngobukhulu bodonga.
I-ASTM A106: Amapayipi ensimbi yekhabhoni angenamthungo afanelekela isevisi yokushisa okuphezulu, ahlukaniswe ngamaBanga A, B, kanye no-C, asetshenziswa kakhulu kumapayipi kawoyela, okudlulisa igesi yemvelo kanye nezimboni zamakhemikhali.
I-ASTM A519: Isebenza kuma-bar namapayipi ensimbi yekhabhoni angenamthungo ngokunemba ukuze kusetshenziswe imishini, enezidingo eziqinile zokubekezelela ubukhulu.
2. Amapayipi Ensimbi Yekhabhoni Ahlanganisiwe
I-ASTM A500: Isebenza esikweleni esihlanganisiwe esibandayo nesingenamthungo,unxandekanye namanye amapayipi ensimbi anesimo sokwakheka, avame ukusetshenziswa ezakhiweni zokwakha.
I-ASTM A501: Isebenza kumapayipi ensimbi ahlanganisiwe ashisiwe futhi angenamthungo ayisikwele, angunxande kanye namanye anomumo ofana nawo.
I-ASTM A513: Isebenza kugesiamapayipi ensimbi ayindilinga ahlanganisiwe, evame ukusetshenziswa ekusetshenzisweni kwemishini kanye nezakhiwo.
3. Amapayipi ensimbi yekhabhoni ama-boiler nama-superheater
I-ASTM A179: Isebenza kumapayipi ebhoyila ensimbi edonswa ngekhabhoni ephansi, afanele ukusetshenziswa komusi ocindezela kakhulu.
I-ASTM A210: Isebenza kumapayipi ebhoyila ensimbi yekhabhoni angenamthungo, ahlukaniswe ngamabanga amane: A1, A1P, A2, kanye ne-A2P, asetshenziswa kakhulu kumabhoyila anomfutho ophakathi nophansi.
I-ASTM A335: Isebenza kumapayipi ensizakalo yokushisa okuphezulu ensimbi ye-ferritic alloy engenamthungo, ahlukaniswe ngama-grade amaningi, njenge-P1, i-P5, njll., afanele amapayipi okushisa okuphezulu embonini ye-petrochemical kanye neyamandla.
4. Amapayipi ensimbi yekhabhoni emithombo kawoyela negesi
I-ASTM A252: Isebenza ku-spiral seam submerged arcamapayipi ensimbi ahlanganisiwengezinqwaba, ezivame ukusetshenziswa ekwakheni amapulatifomu asogwini lolwandle.
I-ASTM A506: Isebenza kumapayipi ensimbi aqinile ane-alloy ephansi, afanelekela ukukhiqizwa kwemishini yasensimini kawoyela negesi.
I-ASTM A672: Isebenza kumapayipi ensimbi e-silicon e-carbon manganese enamandla amakhulu, afanele ukusetshenziswa adinga amandla aphezulu.
I-API Spec 5LNakuba kungeyona indinganiso ye-ASTM, iyindinganiso eyamukelwa emhlabeni wonke yamapayipi ensimbi yamapayipi kawoyela negesi, ehlanganisa izinhlobo eziningi zamapayipi ensimbi yekhabhoni.
5. Amapayipi ensimbi yekhabhoni ngezinjongo ezikhethekile
I-ASTM A312: Isebenza kumapayipi ensimbi engagqwali angenamthungo futhi ahlanganisiwe. Nakuba ikakhulukazi ingeyensimbi engagqwali, ihlanganisa nezinye izici zensimbi yekhabhoni.
I-ASTM A795: Isebenza kuma-billet ensimbi yekhabhoni kanye ne-alloy steel, ama-billet ayindilinga kanye nemikhiqizo yawo eyenziwe ngokuphotha okuqhubekayo kanye nokwakha, afanelekela izinkambu ezithile zezimboni.
Indlela yokukhetha indinganiso efanele ye-ASTM
Ukukhetha indinganiso efanele ye-ASTM kuncike ezidingweni ezithile zesicelo:
Indawo yokusebenzisa: Cabangela izici ezifana nokushisa kokusebenza, izimo zokucindezela, kanye nokuba khona kwezinto ezigqwalisayo.
Izakhiwo zemishini: Nquma amandla amancane okukhiqiza adingekayo, amandla okudonsa kanye nezinye izinkomba ezibalulekile.
Ukunemba kobukhulu: Kwezinye izinhlelo zokusebenza zomshini noma zokuhlanganisa ngokunemba, kungadingeka ukubekezelela ububanzi bangaphandle kanye nokujiya kodonga okulawulwa ngokuqinile.
Ukwelashwa kwendawo: Kungakhathaliseki ukuthi kudingeka i-hot-dip galvanizing, ukupenda noma ezinye izindlela zokwelapha ezilwa nokugqwala.
