Iyini i-ASTM A252?

I-ASTM A252 iyindinganiso eyenzelwe ngokukhethekile ukusetshenziswa namashubhu ensimbi enqwaba yamapayipi.

I-ASTM A252 isebenza ezingqungqutheleni zamapayipi lapho isilinda sensimbi sisebenza njengelungu eliphethe umthwalo unomphela, noma njengegobolondo ukwenza izinqwaba zikakhonkolo ezifakwe endaweni.

Ibanga lesi-2 kanye nebanga lesi-3 ngamabili ala mabanga.

I-ASTM A252/A252M -2019

Ibanga le-ASTM A252

I-A252 ihlukaniswe yaba amamaki amathathu anezici zemishini ezithuthukisiwe ngokulandelana.

Kwakuyizi: Grade 1, Grade 2, kanyeIbanga lesi-3.

IBanga lesi-2 kanye neBanga lesi-3 amamaki asetshenziswa kakhulu ku-ASTM A252, futhi sichaza izici zawo womabili amabanga ngokuningiliziwe ngokulandelayo.

Izinqubo Zokukhiqiza

I-ASTM A252ingenziwa nge-seamless, i-resistance welding, i-flash welding, noma izinqubo ze-fusion welding.

Ekusetshenzisweni kwenqwaba yamapayipi, amashubhu ensimbi angenamthungo ahlinzeka ngokusekela okuhle kakhulu ngenxa yamandla awo aphezulu kanye nezici zamandla afanayo.

Ngaphezu kwalokho, amashubhu ensimbi angenamthungo angenziwa ngogqinsi oluwugqinsi kakhulu lwezindonga, oluwavumela ukuba amelane nokucindezeleka okukhulu, athuthukise ngokwengeziwe ukwethembeka kwawo ezakhiweni zokusekela.

Kodwa-ke, amapayipi ensimbi angenamthungo angakhiqizwa aze afike kububanzi obungu-660 mm, okunciphisa ukusetshenziswa kwawo ezinhlelweni ezidinga izinqwaba ezinkulu zobubanzi.Esimweni esinjalo,I-LSAW(Longitudinal Submerged Arc Welded) kanyeI-SSAW(Spiral Submerged Arc Welded) amapayipi ensimbi anenzuzo enkulu.

I-Chemical Composition ye-ASTM A252 Ibanga lesi-2 neBanga lesi-3

Okuqukethwe kwe-phosphorus akufanele kudlule u-0.050%.

Azikho ezinye izici ezidingekayo.

Amandla Aqinile kanye Namandla Okukhiqiza noma Iphuzu Lokukhipha

	Ibanga lesi-2	Ibanga lesi-3
Amandla aqinile, imiz	60000 psi[415 MPa]	60000 psi[415 MPa]
Iphoyinti lesivuno noma Amandla Okukhiqiza, imiz	35000 psi[240 MPa]	45000 psi[310 MPa]
