Ipayipi Lensimbi Engenamthungo Ukufakwa, Amazinga kanye Nebanga.

Amapayipi ensimbi angenamthungo asetshenziswa kabanzi ezimbonini ezahlukahlukene zokuthutha uketshezi namagesi, kanye nezinhlelo zokusebenza zesakhiwo. Akhiqizwa ngaphandle kokushisela noma imithungo, okwenza aqine futhi athembeke kakhudlwana. Imininingwane, amazinga, kanye namazinga e-amapayipi ensimbi angenamthungokungahluka kuye ngezidingo ezithile zesicelo. Nazi ezinye izincazelo ezivame ukusetshenziswa, amazinga, kanye namazinga amapayipi ensimbi angenamthungo:

Imininingwane:I-ASTM A106-Incazelo Ejwayelekile Yepayipi Lensimbi Yekhabhoni Elingenamthungo Lensizakalo Yokushisa Okuphezulu

1. Le ncazelo ihlanganisa ipayipi lensimbi yekhabhoni elingenamthungo lokusetshenziswa kwezinga lokushisa eliphezulu. Ihlanganisa amazinga ahlukahlukene afana no-A, B, no-C.

Imininingwane:I-ASTM A53-Incazelo Ejwayelekile Yepayipi, Insimbi, Emnyama Neshisayo Ecwiliswe, Embozwe Ngezinki, Ehlanganisiwe Futhi Engenamthungo

1. Le ncazelo ihlanganisa ipayipi lensimbi elimnyama nelicwebezelisiwe elifakwe ngogesi elishisayo. Ihlanganisa amazinga ahlukahlukene afana no-A, B, no-C.

Imininingwane:I-API 5L- Imininingwane yepayipi yomugqa

1. Lokhu kuchazwa kuhlanganisa ipayipi lensimbi elingenamthungo nelihlanganisiwe lezinhlelo zokusebenza ezahlukahlukene. Kufaka phakathi amamaki ahlukene afana nalawaI-API 5L Ibanga B, X42, X52, X60, X65, njll.

ukucaciswa:I-ASTM A252-ichaza izidingo zamapayipi ensimbi ahlanganisiwe futhi angenamthungo ukuze asetshenziswe ekwakheni nasekusetshenzisweni kwesakhiwo.

1. Imininingwane ye-ASTM A252 ihlanganisa amazinga amathathu ezinqwaba zamapayipi ensimbi: Ibanga 1, Ibanga 2, kanye neBanga 3. Ibanga ngalinye linezakhiwo ezahlukene zemishini, kufaka phakathi amandla amancane okukhiqiza kanye namandla amancane okudonsa, ukuze kuhlangatshezwane nezidingo ezithile zephrojekthi.
