GB/T5310-2008faagaau uamea seamless o se ituaiga o paipa uamea maualuga. Ua vaevaeina le paipa fa'afu i totonu o le fa'afufu fa'aauala lautele ma le fa'alava fa'alava maualuga maualuga e tusa ai ma lona fa'atinoga maualuga o le vevela. O paipa fa'afuga maualuga e masani ona fa'aaogaina mo le gaosiga o le maualuga o le mamafa ma luga atu o le mamafa o le ausa, paipa ma isi mea e sili ona lelei o le carbon structural sila, u'amea faumea faumea ma le fa'avevela vevela fa'afefe u'amea paipa. [1] O nei paipa faʻafefe e faʻaogaina i le maualuga o le vevela ma le mamafa, e maua ai le vevela maualuga o le kasa ma le ausa vai, lea e faigofie i le faʻamaʻiina ma le pala.

O le vasega uamea

(1) High quality carbon structural steel steel 20G, 20MnG, 25MnG. 

(2) Alloy fausaga uamea 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, ma isi. 

(3) u'a vevela resistant u'amea masani fa'aaogaina 1Cr18Ni9, 1Cr18Ni11Nb faagaau fa'alava i le fa'aopoopoina ina ia mautinoa le tuufaatasiga o vaila'au ma mea fa'ainisinia, e faia ai le su'ega o le mamafa o le vai, e fai ai le fa'amumu, su'ega fa'amalosi. O paipa uamea o loʻo tuʻuina atu ile tulaga vevela. 

E le gata i lea, e manaʻomia foʻi le microstructure, le saito ma le decarburization layer o faʻamaʻi uamea.

I le faaopoopo atu i le faagaau u'amea seamless faagaau uʻamea maualugaGB/T5310-2008taʻua i luga, o oloa autu a le matou kamupani o:
