Insimbi ye-Womicingumkhiqizi ohamba phambili kanye nomthekelisi womhlaba wonke weISO 3183 L360NE amapayipi ensimbi angenamthungo, ukuhlinzeka ngamapayipi olayini wensimbi ekhabhoni asebenza kahle kakhulu egesi yemvelo nezinhlelo zamapayipi e-petroleum. Imikhiqizo yethu ikhiqizwa ngokuhambisana ngokugcwele nohlelo lwakamuva lweISO 3183(Izimboni zePetroleum negesi yemvelo - Ipayipi lensimbi lezinhlelo zokuthutha amapayipi), ikakhulukazi ngaphansi kweI-L360NEgrade — ipayipi lomugqa elijwayelekile, eliqinile.
1. Uhlolojikelele Olujwayelekile Nomkhiqizo
Igama LomkhiqizoI-ISO 3183 L360NE Ipayipi Lensimbi Elingenamthungo (SMLS)
Okujwayelekile: ISO 3183:2019
IbangaIngxenye #:L360NE
I-“L360” ikhombisa amandla amancane esivuno angama-360 MPa
“N” ishoKwenziwa ngokwejwayelekileisimo sokulethwa
“E” idinga ukuqina okuthuthukisiwe nokuhambisana ngokugcwele nezinga le-PSL2
ISO 3183 L360NE SMLS amapayipiasetshenziswa kakhulu kumapayipi egesi yemvelo amabanga amade, ezokuthutha zikawoyela negesi, amapayipi okuhluza, kanye nezinhlelo zokudlulisa umfutho ophezulu, ikakhulukazi ezindaweni ezinezinga lokushisa eliphansi ezidinga ukumelana nomthelela omkhulu.
