API 5L PSL2LSAW paipa uamea
LSAW paipa uʻamea o loʻo gaosia i uʻamea i totonu o le fale gaosia ma faʻafefeteina i totonu o le ogaumu eletise, faʻafefeteina i slags synthetic ma lafo e casters faifai pea.O le faiga uamea fa'aogaina e fa'amautinoa ai le ausiaina o u'amea mama mama ma fa'asino i le sulfur ma le phosphor i totonu e maua ai le maualuga o le tensile, ductility ma le corrosion resistance properties o paipa e fa'agaioia i le maualalo o le vevela i ala fa'asalalau fa'aleaga.
O le taʻavale e faʻaaoga ai se masini faʻapipiʻi lolomi ma faʻaauau le vili faʻapipiʻiina i se mandrel tumau e mafai ai ona maua faʻapalepale fua ma faʻamautinoa le leai o se paipa tino ma faʻaletonu i luga.
Ina ia ausia le maualuga tensile ma ductility uamea faapea foi ma lona fausaga manaomia, tuuina atu o se tetee corrosion maualuga i ala o faasalalauga corrosion eseese, o paipa e vevela togafitia i totonu o se ogaumu uila savali komepiuta.70% o paipa laina suauʻu e noatia i le vevela.
O paipa e asiasia mo tafega i totonu ma fafo e ala i suʻega aunoa ma le faʻaleagaina o suʻesuʻega ultrasonic ma electromagnetic.Fa'ai'u le su'esu'ega o paipa pe a mae'a le fa'ata'amilosaga e ala ile su'esu'eina o mea sese fa'amaneta-fluoroscopic.
A'o gaosiga o paipa laina e fa'amautinoaina le su'eina o meatotino e tete'e i le pala e ala i le hydrogen e aofia ai auala ta'e i lalo ole NACE MR 02-84 ma le sulphide stress corrosion ta'e auala ile NACE MR 01-77.
Api 5l gr.bpaipa leai se su'ega
O le faʻamoemoega o le api 5l gr.b seamless paipa e talafeagai mo le faʻaaogaina i le felauaiga o le kesi, vai, ma le suauʻu i mea uma e lua suauʻu ma kesi masani.

API 5L X52 paipa uamea
API 5l X52 o le suauu paipa tulaga.
O le API SPEC 5L e aofia ai paipa laina laina ma paipa laina uelo.
Fa'aoga: mo le suau'u, alamanuia kasa masani, okesene, vai, paipa suauu;e mafai foi ona faʻaaogaina i le fausiaina o atinaʻe faʻainisinia, le faʻamatagofieina o auala o Linyuan, alavai alavai, fale matau uamea fale, olo malosi-voltage.
