O loʻo tatala le paipa faʻalava i pito uma e lua ma o loʻo i ai se vaega gaogao, o le umi ma le siʻosiʻomaga o le uʻamea tele, e tusa ai ma le gaosiga o auala e mafai ona vaevaeina i paipa uʻamea seamless ma paipa uʻamea, faʻamatalaga paipa uʻamea ma fua lautele (e pei o le diameter po o le umi) ma le mafiafia o le puipui, fai mai lona tele tele lautele lautele, mai le capillary laʻititi laʻititi seia oʻo i le tele o mita le lautele, paipa lapoa lapoa.

E mafai ona faʻaaogaina paipa uʻamea mo paipa, mea vevela, masini masini, suʻesuʻega faʻafanua suauʻu, pusa, vailaʻau kemisi ma faʻamoemoega faʻapitoa.

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

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

E lua vaega e lua o le paipa vai:GB/T3087-2018vaeluaga ma le maualalo o le faagaau faumea,GB/T5310-2018faagaau fauvela maualuga. O a matou oloa autu e aofia ai:
