Umbhobho owenziwe kwi-ASTM106 iBanga A okanye B awutshintshiswano nge-API 5L. Iimfuno kwi-API 5L X amabakala angqongqo kakhulu; amabakala aqengqelekayo awamkelekanga kwaye ukusetyenzwa kwakhona akuvumelekanga. Ngaphezu koko, ingqalelo ekhethekileyo inikwa ukuqina kunye novavanyo lokuqina kwiinkonzo ezimuncu kunye noxinzelelo oluphezulu kunye neeklasi zobushushu.
Amanqanaba okuqina kunye ne-DesulphurizationI-Manganese sulphides zizinto eziqhelekileyo zokufakwa kuzo zonke iintsimbi ezenziwe nge-manganese. Ngenxa yokuba zikholisa ukwahlula okukhokelela ekunciphiseni amandla empembelelo, umxholo wesalfure kufuneka uncitshiswe. Sichaza ubuninzi be-0.007%.
Izibonelelo ze-API 5L kunye nezicelo Igesi, amanzi kunye ne-oyile yokuhamba-ikhethwa kwimibhobho emide ngenxa yokungabizi.I-American Petroleum Institute specication API 5L idilesi umbhobho womgca wentsimbi ongenamthungo kunye ne-welded kwiinkqubo zokuthutha iipayipi kwi-petroleum kunye negesi yendalo. I-API 5L ilungele ukuhambisa igesi, amanzi kunye ne-oyile.
Iinkcukacha ze-API 5L zihambelana ne-International Organisation for Standardization ISO 3183, ukulinganisa iinkqubo zothutho lwemibhobho ngaphakathi kwemathiriyeli, izixhobo kunye nezakhiwo ezikude nonxweme zegesi yendalo, i-petroleum, kunye ne-petrochemical industry. Xa ugunyazisa imigangatho, ikomiti yezobugcisa yaqaphela ukuba kukho amaNqanaba eNkalo yeMveliso esisiseko (PSL) yeemfuno zobugcisa kwaye ngoko iphuhliswe i-PSL 1 kunye ne-PSL 2. I-PSL 1 ngumgangatho oqhelekileyo wombhobho womgca apho i-PSL 2 iqulethe iikhemikhali ezongezelelweyo, iipropati zomatshini. , kunye neemfuno zovavanyo.
Amabakala afundiswayo ngala maBakala A25, A, B no-"X" X42, X46, X52, X56, X60, X65, X70, and X80. Inani leedijithi ezimbini ezilandela u-"X" libonisa aManinzi aManinzi eSivuno sokuGcina (ngo-000's psi) wombhobho oveliswe kweli bakala.
