I-ASTM A252:Ucaciso oluQhelekileyo lweePipu zeNtsimbi eziWelded kunye nezingenamthungo.
Le ngcaciso ihlanganisa i-nominal (i-avareji) yodonga lwentsimbi yombhobho iimfumba zemilo ye-cylindrical kwaye isebenza kwiimfumba zemibhobho apho i-cylinder yentsimbi isebenza njengelungu elisisigxina eliphethe umthwalo, okanye njengeqokobhe ukwenza iimfumba zekhonkrithi ezifakwe kwindawo.Iimfumba zemibhobho ziveliswa njengeemveliso ezidityanisiweyo nezingenamthungo.

IBanga le-ASTM A252
Amabanga e-ASTM A252 ahlelwa njengeBakala 1 iBanga lesi-2 kunyeIBanga lesi-3.
Inkqubo yeMveliso yezinto ezikrwada
Insimbi iya kwenziwa yinye okanye ngaphezulu kwezi nkqubo zilandelayo: i-open-hearth, i-basic-oxygen, okanye isithando sombane.
Izixhobo kunye nokuVeliswa
Iimfumba ziya kwenziwa ngokungenamthungo, ukunganyangeki kombane okudityanisiweyo, okudityanisiweyo okudityanisiweyo, okanye inkqubo edityanisiweyo edityanisiweyo.
Imithungo yeemfumba zemibhobho edityanisiweyo iya kuba yi-longitudinal, i-helical-butt, okanye i-helical-lap.
I-ASTM A252 Ukuqulunqwa kwemichiza
Indlela yovavanyo: ASTM A751.
Intsimbi ayiyi kuba ngaphezu kwe-0.050 % ye-phosphorus.Oku kungenxa yokuba amanqanaba aphezulu e-phosphorus anokubangela ukuba intsimbi ibe brittle kumaqondo obushushu aphantsi, ukunciphisa ukuqina kwemathiriyeli.
Ukucaciswa kwe-ASTM A252 ineemfuno ezilinganiselweyo zokwakheka kweekhemikhali: oku kungenxa yokuba i-ASTM A252 isebenza ngokuyintloko kwizicelo zesakhiwo, ngakumbi njengezinto ezithwala umthwalo, apho iimpawu ezibonakalayo (njengamandla esivuno, amandla okuqina, kunye nobude) zibaluleke ngakumbi kunokwakheka kweekhemikhali. .Ezi zakhiwo zomzimba zinokufezekiswa ngokuvelisa okufanelekileyo kunye neenkqubo zokunyanga ukushisa ngaphandle kokulawulwa okungqongqo kokwakheka kweekhemikhali ngaphandle kwe-phosphorus.
Iimfuno ze-ASTM A252 ze-Tensile
Indlela yovavanyo: ASTM A370.
Uvavanyo loxinzelelo lweHydrostatic
Isizathu sokuba i-ASTM A52 ingacacisi uvavanyo lwe-hydraulic ngokuyinhloko ngenxa yeempawu zesicelo kunye neemfuno zoyilo lwale mibhobho.
Kwiimfumba zepayipi zensimbi kwinkcazo ye-ASTM A252, injongo yoyilo oluphambili kukumelana nemithwalo ye-axial, kungekhona uxinzelelo lwangaphakathi.Oku kuchasene nemibhobho yokuthutha ulwelo okanye iigesi, ezifana nezo ziphantsi kwe-API 5L yenkcazo, ekufuneka ibekwe phantsi kovavanyo oluthe ngqo loxinzelelo lwangaphakathi ukuqinisekisa ukuqina kunye namandla.

Iziphene zoMphezulu wePipe
1. Ukungafezeki komphezulu okunobunzulu obungekho ngaphezulu kwe-12.5 % yobukhulu bodonga obuxeliweyo kuya kwamkeleka.
Kuya kuvunyelwa ukuseka ubunzulu bokungafezeki okunjalo ngokusila okanye ukufayila.
2. Iziphene zomphezulu ezinobunzulu obungaphezulu kwe-12.5% yobukhulu bodonga obuxeliweyo buya kuthathwa njengeziphene.
Kuya kuvunyelwa ukuba iziphene zingekho ngaphantsi kwe-33.3% yobukhulu obuchaziweyo bodonga oluchaziweyo oluya kulungiswa nge-welding, ngaphandle kokuba i-defect isuswe ngokupheleleyo ngaphambi kokufakwa.
IsiXhobo
Izicelo ze-ASTM A252 zeBanga loku-1
Iiprojekthi ezilayishwe kancinci kwiimeko zomhlaba jikelele, ezifana neziseko zezakhiwo ezincinci okanye izakhiwo.
Iziseko zezakhiwo zexeshana ezifana nenkxaso yokwakha okanye iibhulorho zexeshana.
Iiprojekthi zokulungiswa kokusingqongileyo kwiimeko ezilungileyo zomhlaba apho kungafuneki uxinzelelo olugqithisileyo.
Izicelo ze-ASTM A252 zeBanga lesi-2:
Iiprojekthi zobunjineli ezineemfuno zokulayisha eziphakathi, kubandakanywa iziseko zezakhiwo ezinemigangatho emininzi okanye izibonelelo.
Iibhulorho, iintsika, kunye neeprojekthi eziselunxwemeni kwiimeko zomhlaba onzima ngokuphakathi.
Sebenzisa kwiimeko ezinomngcipheko othile wokonakala kweekhemikhali okanye ukhukuliseko.
Izicelo ze-ASTM A252 zeBanga lesi-3:
Iiprojekthi ezibalulekileyo phantsi kweemeko zomhlaba ezithwele kakhulu, ezinzima ezifana neebhulorho ezinkulu, izakhiwo eziphakamileyo, kunye neendawo ezinkulu zemizi-mveliso.
Iindawo ezinobungozi obuphezulu, ezifana nezakhiwo ezixhomekeke kukhukuliseko olumandla, ukonakala kweekhemikhali, okanye iimeko zemozulu ezimandundu.
Iiprojekthi ezinkulu ezingaselunxwemeni, ezinje ngeziseko zeejethi zamanzi anzulu, iindawo zokuqhawula amanzi, kunye namaqonga e-oyile negesi.
