I-PSL1, i-PSL2 kunye ne-Acidic Media Types.
Ngokuqhelekileyo kusetyenziswa i-PSL1, elingana ne-ASTM A106 B kunye ne-A53 B.
I-PSL2 ngumbhobho wodidi oluchaziweyo oluphezulu oneemfuno ezingqongqo zokomelela kweekhemikhali kunye noomatshini.I-PSL2 ifuna iindlela ezininzi zovavanyo ezifana novavanyo olungonakalisi, uvavanyo lwempembelelo ye-CVN, i-DWT, njl.
I-API 5L B PSL2 imelwe yi-API 5L BN/Q/R/M.
Umbindi weAcidic: Kwimibhobho yeasidi efana nokusingqongileyo kwe-H2S, imathiriyeli yombhobho ineemfuno eziqhelekileyo zezinto zekhemikhali ezifana nekhabhoni, iphosphorus kunye nesalfure.Umgangatho weReference NACE MR0175.
Oonobumba abasisimamva baxela iimeko zokuhanjiswa kombhobho:
R: Xa uqengqeleka.
N: ukulungelelanisa ukuqengqeleka, ukubunjwa kwesiqhelo, ukulungelelanisa.
Umbuzo: Ukunciphisa kunye nokunciphisa.
M: Ukuqengqeleka kwe-Thermomechanical okanye ukwenza i-thermomechanical.
