O paipa ua gaosia ile ASTM106 Vasega A po'o le B e le mafai ona fesuia'i ma le API 5L. Manaoga ile API 5L X togi e sili atu ona faʻamalosi; e le talia togi taai ma e le fa'atagaina le toe fai. E le gata i lea, e fa'apitoa le tu'uina atu i su'ega faigata ma faigata mo 'au'aunaga oona ma vasega maualuga o le mamafa ma le vevela.
Tulaga Malosi & DesulfurizationManganese sulphides o mea masani ia e aofia ai i uʻamea faʻafefiloi uma. Talu ai e matele ina fa'a'ese'ese ma fa'aitiitia ai le malosi o le a'afiaga, e mana'omia le fa'aitiitia o mea e maua mai i le sulphure. Matou te faʻamaonia le maualuga 0.007%.
API 5L Fa'amanuiaga & Talosaga Kesi, vai ma suau'u felauaiga - e sili i paipa umi ona o le taugofie.O le American Petroleum Institute specification API 5L o loʻo tuʻuina atu le faʻaogaina o le paipa laina uʻamea mo paipa auala felauaiga i totonu ole suauʻu ma kesi masani alamanuia. API 5L e talafeagai mo le felauaiga kesi, vai, ma suauu.
Fa'amatalaga mo le API 5L o lo'o mulimulita'i i le International Organization for Standardization ISO 3183, fa'avasegaina o faiga o felauaiga o paipa i totonu o meafaitino, masini ma fausaga i fafo mo kesi fa'alenatura, suau'u, ma alamanuia petrochemical. I le tu'uina atu o tulaga fa'ata'atia, na iloa e le komiti fa'apitoa e lua Laasaga Fa'amatalaga Fa'amatalaga (PSL) o mana'oga fa'apitoa ma o lea na atia'e ai le PSL 1 ma le PSL 2. O le PSL 1 o se tulaga fa'apitoa mo paipa laina lea o lo'o i ai i le PSL 2 isi vaila'au, mea fa'ainisinia. , ma mana'oga mo su'ega.
O togi o lo'o aofia i lenei fa'amatalaga o A25, A, B ma le "X" Vasega X42, X46, X52, X56, X60, X65, X70, ma le X80. O le numera numera lua o lo'o mulimuli mai i le "X" o lo'o fa'ailoa mai ai le Malosi Fa'asili maualalo (i le 000's psi) o paipa ua gaosia i lenei vasega.
