Ekusetshenzisweni kwezimboni, amapayipi ensimbi adlala indima ebalulekile ekuqinisekiseni ukuthuthwa okuphumelelayo koketshezi namagesi.Izimboni ezahlukene zidinga izinhlobo ezithile zamapayipi ensimbi, kuye ngezidingo nezimo zabo eziyingqayizivele.Namuhla, sibhekisisa ukuguquguquka okumangalisayo namandla anikezwa izinto ezintathu ezibalulekile zamapayipi ensimbi: I-ASTM A53 Gr.Ipayipi lensimbi elibhayela, ipayipi le-ASTM A192, ne-API 5L Gr.B ipayipi lensimbi elingenamthungo.
I-ASTM A53 GR.Bipayipi yensimbi ye-boiler:
I-ASTM A53 GR.B ipayipi lensimbi likabhoyela liyibanga lepayipi lensimbi elakhelwe izinga lokushisa eliphezulu kanye nezicelo zengcindezi ephezulu kuma-boilers nezishintshisi zokushisa.Ikhiqizwa kusetshenziswa i-carbon ne-alloying elements ukuze iqine futhi imelane nokucindezeleka kokuqhekeka kokugqwala.Ukwengeza, i-ASTM A53 Gr.Amapayipi ensimbi ka-boiler anokuqukethwe kwekhabhoni ephezulu kunamapayipi ajwayelekile, anikeza amandla amakhulu nokuqina.
Ipayipi le-ASTM A192:
Enye into enhle kakhulu yamapayipi ensimbi yipayipi le-ASTM A192, elisetshenziswa ngokuyinhloko ezinhlelweni zamabhoyela anengcindezi ephezulu kanye nezishintshisi zokushisa.Ipayipi le-ASTM A192 lakhiwe ngensimbi yekhabhoni yekhwalithi ephezulu enezakhiwo ezinhle kakhulu zemishini nokumelana okuhle nezingcindezi zangaphakathi nezangaphandle.
I-API 5L GR.B ipayipi lensimbi engenamthungo:
I-API 5L GR.B yakhelwe ukuthuthwa kwegesi yemvelo, uwoyela nolunye uketshezi.Amapayipi ensimbi angenamthungo ayinketho ethandwayo embonini kawoyela negesi.Le nto yepayipi yensimbi inokumelana okuhle kakhulu nokucindezeleka kwemishini kanye nokugqwala, okwenza kube ekahle ezimweni ezinzima.
Ukusuka kuma-boilers kuya kulayini wokuhambisa uwoyela negesi, i-ASTM A53 Gr.Bipayipi yensimbi ye-boiler, ipayipi le-ASTM A192 ne-API 5L Gr.Ipayipi lensimbi elingenamthungo linokusetshenziswa okuhlukile ezimbonini ezahlukahlukene.Lezi zinto ezikhethekile zamapayipi ensimbi zinezakhiwo ezihlaba umxhwele ezifana nokumelana nokushisa okuphezulu, ukumelana nokugqwala kanye namandla amahle kakhulu emishini.
