I se tulaga lautele, API 5L e faasino i le API 5L laina paipa, lea e i fafo o le eleele le suauu, kesi, vai, felauaiga i paipa i paipa suauu ma kamupani alamanuia kasa.

e tusa ai ma le faagasologa o le gaosiga ma le fuga paipa faʻaaogaina foliga eseese, e mafai ona vaevaeina api 5l i le api 5l paipa uʻamea seamless ma api uʻamea paipa uamea, i totonu o le aofaʻi faʻaaogaina o paipa uamea e sili atu nai lo paipa uamea.

Vasega paipa laina ma vaega vailaʻau

API 5L e mafai ona vaevaeina i API 5L PSL 1 ma API 5L PSL 2, e aofia ai API 5L PSL 1 tulaga ma vaega o: A, B, x42, x46, x52, x56, x60, x65, x70, API 5L PSL 2 tulaga. ma o le vaega o le B, x42, x46, x52, x56, x60, x65, xx70, x80.o le maualuga o le maualuga o le malosi o mea faʻainisinia.

Talosaga: faʻaaogaina mo le suauʻu ma le kesi alamanuia, kesi, vai, felauaiga suauu.
