Amathegi Omkhiqizo

Kuyini i-ASTM A252?

I-ASTM A252 iyindinganiso eyenzelwe ngqo ukusetshenziswa ngamapayipi ensimbi ahlanganisiwe.

I-ASTM A252 isebenza ezinqwabeni zamapayipi lapho isilinda sensimbi sisebenza njengelungu elihlala njalo elithwala umthwalo, noma njengegobolondo lokwenza izinqwabeni zekhonkrithi ezifakwe endaweni.

Ibanga lesi-2 nebanga lesi-3 yizo ezimbili zalezi zigaba.

I-ASTM A252/A252M -2019

Ibanga le-ASTM A252

I-A252 ihlukaniswe ngamagremu amathathu anezakhiwo zemishini ezithuthukisiwe ngokulandelana.

Kwakuyi: Ibanga 1, Ibanga 2, kanyeIbanga lesi-3.

Ibanga lesi-2 nebanga lesi-3 yizona ezisetshenziswa kakhulu ku-ASTM A252, futhi sizochaza izakhiwo zazo zombili lezi zigaba ngokuningiliziwe ngokulandelayo.

Izinqubo Zokukhiqiza

I-ASTM A252ingakhiqizwa ngezinqubo zokushisela ezingenamthungo, zokumelana, zokushisela nge-flash, noma zokushisela nge-fusion.

Ekusetshenzisweni kwenqwaba yamapayipi, amashubhu ensimbi angenamthungo anikeza ukwesekwa okuhle kakhulu ngenxa yamandla awo aphezulu kanye nezici zamandla ezifanayo.

Ngaphezu kwalokho, amashubhu ensimbi angenamthungo angenziwa ngobukhulu bodonga obukhulu kakhulu, okuwavumela ukuthi amelane nokucindezeleka okukhulu, okuthuthukisa ukuthembeka kwawo ezakhiweni zokusekela.

Kodwa-ke, amapayipi ensimbi angenamthungo angakhiqizwa afinyelela kububanzi obuphezulu obungu-660 mm, okunciphisa ukusetshenziswa kwawo ezicelweni ezidinga amanqwaba amakhulu obubanzi. Kulokhu,I-LSAW(I-Longitudinal Submerged Arc Welded) kanyeI-SSAWAmapayipi ensimbi (ahlanganiswe nge-Spiral Submerged Arc Welded) anenzuzo enkulu.

Ukwakheka Kwamakhemikhali kwe-ASTM A252 Ibanga 2 kanye neBanga 3

Okuqukethwe kwe-phosphorus akufanele kudlule u-0.050%.

Azikho ezinye izakhi ezidingekayo.
