Paipa API 5Lo se paipa u'amea kaponi e masani ona fa'aaogaina i pisinisi suau'u ma kesi. E avea fo'i o se auala e feavea'i ai isi vai e pei o le ausa, vai ma le palapala.

Ituaiga o Gaosiga

E fa'aoga le API 5L i paipa uelo ma paipa e leai ni so'oga

Ituaiga Fa'apipi'i: Paipa ERW, SAW, DSAW, LSAW, SSAW, HSAW

O ituaiga masani o paipa API 5L ua fa'apipi'iina e pei ona taua i lalo:

ERWO le fa'avevela tete'e eletise e fa'aaogaina mo paipa e itiiti ifo i le 24 inisi le lautele.

DSAW/ SAWO le fa'avelaina o le arc i lalo o le vai e lua itu/fa'avelaina o le arc i lalo o le vai o se isi metotia o le fa'avelaina e mafai ona fa'aaoga e sui ai le ERW mo paipa tetele.

LSAWO le Longitudinal Submerged Arc Welding e fa'aaogaina mo paipa e o'o atu i le 48 inisi le lautele. Ua lauiloa o le faiga o le JCOE forming.

SSAW/HSAW: Fa'avelaina o le arc i lalo o le vai fa'asolo/fa'avelaina o le arc i lalo o le vai fa'asolo e o'o atu i le 100 inisi le lautele o le paipa.

Fa'afeso'ota'i matou e iloa ai eseesega i le va o paipa ERW, LSAW, ma le SSAW.

Ituaiga Paipa e leai se Su'i: Paipa e leai se Su'i e vili vevela ma Paipa e leai se Su'i e vili malulu

O paipa e leai ni so'oga e masani ona fa'aaogaina mo paipa laiti le lautele (e masani lava e itiiti ifo i le 24 inisi).

(E masani ona fa'aaogaina paipa u'amea e leai ni so'oga nai lo paipa uelo mo paipa e la'ititi ifo i le 150 mm (6 inisi).

Matou te fa'atauina fo'i paipa e leai ni so'oga tetele. Fa'aaogaina le metotia fa'avevela e mafai ona matou gaosia se paipa e leai ni so'oga e o'o atu i le 20" (508 mm) le lautele. Afai e te mana'omia se paipa e leai ni so'oga e sili atu i le 20" le lautele, e mafai ona matou gaosia e o'o atu i le 40" (1016 mm) le lautele e ala i le metotia fa'avevela.

Vasega Paipa API 5L

O lo'o fa'amaoti mai e le API 5L vaega nei: Vasega B, X42, X46, X52, X56, X60, X65, X70, ma le X80.

E tele ituaiga eseese o u'amea mo paipa u'amea API 5L e pei o le Vasega B, X42, X46, X52, X56, X60, X65, X70, ma le X80. Faatasi ai ma le faateleina o le vasega u'amea, ua sili atu ona matua pulea le tutusa o le kaponi, ma ua maualuga atu foi le malosi fa'amekanika.

E le gata i lea, o le tuufaatasiga vailaʻau o paipa API 5L e leai ni soʻoga ma paipa faʻapipiʻi mo se vasega faapitoa e le tutusa, o le paipa faʻapipiʻi e sili atu ona maualuga le manaʻoga ma itiiti le aofaʻi o le kaponi ma le sulfur.
