Ipayipi lensimbi elingenamthungoI-ASTM A53, SCH40, Gr.B ipayipi lensimbi lekhwalithi ephezulu elisetshenziswa kabanzi emakethe, elisebenza kahle nezinkambu zohlelo lokusebenza ezihlukene. Okulandelayo yisingeniso sezinzuzo zaleli payipi lensimbi:

Material kanye Standard
I-ASTM A53okujwayelekile kuwukucaciswa okuqinile kwamapayipi ensimbi angenamthungo embonini yensimbi yase-US, asetshenziselwa ikakhulukazi uwoyela, igesi yemvelo, umusi namanye amapayipi. Leli payipi lensimbi lenziwe nge-carbon steel noma i-low alloy steel. IBanga B (Gr.B) libonisa ukuthi ipayipi inamandla aphezulu nokumelana nokucindezela futhi ifanele izindawo zokucindezela okuphakathi nendawo. I-SCH40 isho izinga lokushuba kodonga lwamapayipi, okuqinisekisa ukuthi ipayipi linokumelana nokugqwala okwanele kanye namandla okuthwala ingcindezi.

Inqubo yokukhiqiza kanye nekhwalithi
Leli payipi lensimbi lamukela ubuchwepheshe bokukhiqiza ipayipi lensimbi elingenamthungo ukuze kuqinisekiswe ikhwalithi yomkhiqizo ozinzile, indawo yepayipi ebushelelezi, akukho zinkinga zokushisela, kanye nokumelana nokucindezela okuhle kakhulu nokumelana nokugqwala. Ngokuhlola okuqinile kwekhwalithi, kuhlangabezana nezidingo zeI-ASTM A53izinga lokuqinisekisa ukuthi amandla, ubulukhuni, i-ductility kanye nokumelana nokugqwala kwepayipi ngalinye lensimbi lihlangabezana namazinga embonini.

Imininingwane kanye nobubanzi bohlelo lokusebenza
Ipayipi lensimbi elingenamthungo linokucaciswa okuhlukahlukene, kufaka phakathi ububanzi obujwayelekile bangaphandle obusuka ku-1/8 "kuya ku-30", futhi ukushuba kodonga kungenziwa ngokwezifiso ngokuya ngezidingo. Isetshenziswa kabanzi emkhakheni we-petroleum, amakhemikhali, amandla kagesi, ukwakhiwa kwemikhumbi, imishini, njll., ifaneleka kakhulu izinhlelo zamapayipi ezihambisa imidiya yoketshezi njengamanzi, uwoyela, negesi.

Isetshenziswa kabanzi
I-ASTM A53ipayipi lensimbi elingenamthungo lingasetshenziselwa amapayipi okudlulisela umfutho ophezulu, izakhiwo zokwakha, amapayipi okubhayela, amapayipi okuhambisa uwoyela negesi yemvelo, njll., ukuzivumelanisa nezimo ezihlukahlukene zokusebenza eziyinkimbinkimbi, ukuhlinzeka ngokusebenza okuthembekile kokuthutha kanye neziqinisekiso zokuphepha.
