IPHAYIPHI LEBANGA B LE-API 5L

Incazelo emfushane:

Igama: Ipayipi le-API 5L lebanga B

I-API 5L iyindinganiso ethandwa kakhulu yamapayipi omugqa athuthukiswe yi-Amercian Petroleum Institute. Ngesikhathi esifanayo, i-ISO3183 kanye ne-GB/T 9711 ziyindinganiso yamazwe ngamazwe kanye nendinganiso yaseShayina yamapayipi omugqa ngokwehlukana. Singakhiqiza amapayipi omugqa ngokwezindinganiso ezintathu ezishiwo.
