Yintoni i-ASTM A252?

I-ASTM A252 ngumgangatho olungiselelwe ngokukodwa ukusetyenziswa kwiityhubhu zentsimbi zepayipi.

I-ASTM A252 isebenza kwiinqwaba zemibhobho apho isilinda yentsimbi isebenza njengelungu elihlala lihleli lokuthwala umthwalo, okanye njengeqokobhe lokwenza iinqwaba zekhonkrithi ezifakwe endaweni yazo.

Ibanga lesi-2 nebanga lesi-3 zezinye zezi zigaba.

I-ASTM A252/A252M -2019

Ibanga le-ASTM A252

I-A252 yahlulwe yangamanqanaba amathathu aneempawu zoomatshini eziphuculweyo ngokulandelelana.

Yayizi: Ibanga loku-1, iBanga lesi-2, kunyeIbanga lesi-3.

Ibanga lesi-2 nebanga lesi-3 zezona zigaba zisetyenziswa kakhulu kwi-ASTM A252, kwaye siza kuchaza ngokweenkcukacha iimpawu zazo zombini ezi zigaba.

Iinkqubo zoMveliso

I-ASTM A252ingenziwa ngeenkqubo zokuwelda ezingenamthungo, ezichasene nokumelana, ezisebenzisa i-flash welding, okanye ezisebenzisa i-fusion welding.

Kwiinkqubo zokufaka iipayipu, iityhubhu zentsimbi ezingenamthungo zibonelela ngenkxaso egqwesileyo ngenxa yamandla azo aphezulu kunye neempawu zamandla ezifanayo.

Ukongeza, iityhubhu zentsimbi ezingenamthungo zinokwenziwa ngobukhulu bodonga obukhulu kakhulu, nto leyo evumela ukuba zimelane noxinzelelo olukhulu, nto leyo ephucula ngakumbi ukuthembeka kwazo kwizakhiwo ezixhasayo.

inkqubo yombhobho-wentsimbi engenamthungo

Nangona kunjalo, imibhobho yentsimbi engenamthungo inokwenziwa ukuya kuthi ga kububanzi obuphezulu obuyi-660 mm, nto leyo ethintela ukusetyenziswa kwayo kwiindawo ezifuna iinqwaba ezinkulu zobubanzi.I-LSAW(I-Longitudinal Submerged Arc Welded) kunyeI-SSAWImibhobho yentsimbi (efakwe kwi-Spiral Submerged Arc Welded) iluncedo ngakumbi.

Ukwakhiwa kweekhemikhali ze-ASTM A252 Ibanga lesi-2 kunye neBanga lesi-3

Umxholo we-phosphorus mawungadluli kwi-0.050%.

Akukho ezinye izinto ezifunekayo.
