Ipayipi elijwayelekile le-ERWzimi kanje:
I-API 5L, ASTM A53 B, ASTM A178, ASTM A500/501, ASTM A691, ASTM A252, ASTM A672

I-API 5L Standard ihlose ukufaka igesi namanzi embonini kawoyela negesi ukuze kubhekiselwe kuyo, esetshenziselwa ipayipi lensimbi elingenamthungo kanye nepayipi lensimbi elishiselwe, okuhlanganisa ichweba elivamile kanye nechweba, imbobo yesokhethi yamapayipi kanye neshubhu lomfudlana oqondile (TFL) kanye nechweba elinendawo ethile. ukucutshungulwa kweshubhu lokuxhuma.

Ipayipi le-ASTM A53 lenzelwe ukusetshenziswa kwemishini nengcindezi futhi liyamukeleka ekusetshenzisweni okuvamile emigqeni yesitimu, amanzi, igesi nomoya.

Izindinganiso ze-ASTM A178 zamashubhu ashiselwe ukumelana nogesi anobukhulu obuncane bodonga enziwe ngensimbi ye-carbon steel kanye ne-carbon-manganese steel azosetshenziswa kumashubhu obhayela, amaflue abhayela, amaflue e-superheater, neziphetho eziphephile.

I-ASTM A500 ihlanganisa ishubhu lensimbi elakhiwe ngendlela ebandayo elishiselwe futhi elingenamthungo eliyindilinga, isikwele, unxande, noma umumo okhethekile wamashubhu okwakhiwa kwamabhuloho namabhilidi ashiselwe, acijile noma abhawudiwe, nangezinhloso zesakhiwo esijwayelekile.

I-ASTM A691 imboza ipayipi lensimbi ye-carbon ne-alloy, i-electric-fusion-welded ene-filler metal eyengeziwe, eyenziwe ngepuleti lekhwalithi yomkhumbi-umshini wokuhlaziya okuningana namazinga wamandla futhi ifanele isevisi yokucindezela okuphezulu emazingeni okushisa aphezulu.

I-ASTM A252 imboza izinqwaba zamapayipi ensimbi ayi-cylindrical lapho isilinda sensimbi sisebenza njengelungu eliphethe umthwalo unomphela noma njengegobolondo ukwenza izinqwaba zikakhonkolo ezifakwe endaweni.

I-ASTM A672 ifaka ipayipi lensimbi likagesi-fusion-welded lesevisi yokucindezela okuphezulu emazingeni okushisa aphakathi nendawo.
