Kodi ASTM A252 ndi chiyani?

ASTM A252 ndi muyezo womwe wapangidwa makamaka kuti ugwiritsidwe ntchito ndi mapaipi achitsulo chozungulira.

ASTM A252 imagwira ntchito pa mapaipi omwe silinda yachitsulo imagwira ntchito ngati chiwalo chonyamula katundu chokhazikika, kapena ngati chipolopolo chopangira milu ya konkire yopangidwa m'malo mwake.

Giredi 2 ndi giredi 3 ndi awiri mwa ma giredi awa.

ASTM A252/A252M -2019

Giredi ya ASTM A252

A252 yagawidwa m'magulu atatu okhala ndi mawonekedwe owonjezera a makina motsatizana.

Iwo anali: Giredi 1, Giredi 2, ndiGiredi 3.

Giredi 2 ndi Giredi 3 ndi magiredi omwe amagwiritsidwa ntchito kwambiri mu ASTM A252, ndipo tikufotokoza mwatsatanetsatane za magiredi onsewa.

Njira Zopangira

ASTM A252Zingapangidwe pogwiritsa ntchito njira zolumikizirana zosasokonekera, zopinga, zowunikira modutsa, kapena zolumikizirana.

Mu ntchito zoyika mulu wa mapaipi, machubu achitsulo opanda msoko amapereka chithandizo chabwino kwambiri chifukwa cha mphamvu zawo zambiri komanso mphamvu zawo zofanana.

Kuphatikiza apo, machubu achitsulo osapindika amatha kupangidwa ndi makulidwe a khoma okhuthala kwambiri, zomwe zimawathandiza kupirira kupsinjika kwakukulu, zomwe zimawonjezera kudalirika kwawo m'mapangidwe othandizira.

Komabe, mapaipi achitsulo osapindika amatha kupangidwa mpaka mainchesi 660, zomwe zimapangitsa kuti asamagwiritsidwe ntchito kwambiri pakufunika milu yayikulu ya mainchesi.LSAW(Longitudinal Submerged Arc Welded) ndiSSAWMapaipi achitsulo (Spiral Submerged Arc Welded) ndi abwino kwambiri.

Kuphatikizika kwa Mankhwala a ASTM A252 Giredi 2 ndi Giredi 3

Kuchuluka kwa phosphorous kusapitirire 0.050%.

Palibe zinthu zina zofunika.
