Yintoni i-ASTM A252?

I-ASTM A252 ngumgangatho ophuhliswe ngokukodwa ukusetyenziswa kunye netyhubhu yentsimbi yombhobho.

I-ASTM A252 isebenza kwiimfumba zemibhobho apho i-cylinder yensimbi isebenza njengelungu elisisigxina eliphethe umthwalo, okanye njengegobolondo ukwenza iimfumba zekhonkrithi ezifakwe kwindawo.

IBakala 2 neBakala 3 ngamabini kula mabakala.

I-ASTM A252/A252M -2019

IBanga le-ASTM A252

I-A252 yahlulwe yangamanqanaba amathathu aneempawu zoomatshini ezandisiweyo ngokulandelelanayo.

Ibiyi: Grade 1, Grade 2, kunyeIBanga lesi-3.

IBanga lesi-2 neBanga lesi-3 ngawona bakala asetyenziswa kakhulu kwi-ASTM A252, kwaye sichaza iimpawu zawo omabini amabanga ngokweenkcukacha ngokulandelayo.

Iinkqubo Zokuvelisa

I-ASTM A252inokuveliswa ngokungenamthungo, i-resistance welding, i-flash welding, okanye iinkqubo ze-fusion welding.

Kwizicelo zeemfumba zepayipi, iibhubhu zensimbi ezingenamthungo zibonelela ngenkxaso ebalaseleyo ngenxa yamandla abo aphezulu kunye neempawu zamandla afanayo.

Ukongeza, iityhubhu zentsimbi ezingenamthungo zinokuveliswa ezinobunzima obukhulu bodonga, ezivumela ukuba zimelane noxinzelelo olukhulu, ziphucule ngakumbi ukuthembeka kwazo kwizakhiwo zenkxaso.

ingenamthungo-yentsimbi-umbhobho-inkqubo

Nangona kunjalo, imibhobho yentsimbi engenamthungo inokuveliswa ukuya kuthi ga kububanzi obungama-660 mm, nto leyo ethintela ukusetyenziswa kwayo kwizicelo ezifuna iimfumba ezinkulu zedayamitha.Kule meko,LSAW(Longitudinal Submerged Arc Welded) kunyeSSAW(Spiral Submerged Arc Welded) imibhobho yentsimbi inenzuzo ngakumbi.

Ukwakhiwa kweMichiza ye-ASTM A252 iBanga lesi-2 kunye neBanga lesi-3

Umxholo wePhosphorus ungagqithi kwi-0.050%.

Akukho ezinye izinto ezifunekayo.
