Alloy seamless paipa uamea o se ituaiga o paipa uʻamea seamless, ma o lona faatinoga e sili atu le maualuga nai lo le masani paipa uʻamea seamless, ona o lenei paipa uamea o loʻo i ai le tele o Cr, ma o lona maualuga maualuga teteʻe, maualalo vevela tetee ma corrosion tetee faatinoga e sili atu nai lo. isi paipa u'amea lamolemole. E le mafaatusalia, o lea e masani ona faʻaaogaina faʻamau faʻapipiʻi i suauʻu, vailaʻau, eletise eletise, pusa ma isi pisinisi. Alloy seamless paipa uʻamea (Seamless Steel Tube) ei ai se vaega omo, o se fasi uamea umi e aunoa ma sooga faataamilo ai. O le paipa uʻamea o loʻo i ai se vaega gaogao ma e faʻaaogaina lautele e fai ma paipa mo le felauaiga o vai, e pei o paipa mo le felauaiga o suauʻu, kesi masani, kesi, vai ma nisi mea mautu. Pe a faatusatusa i le uamea malo e pei o le u'amea lapotopoto, o le paipa u'amea sologa lelei e tutusa le malosi fesui ma torsional ma mama mama. O se uʻamea vaega tau tamaoaiga ma faʻaaogaina lautele i le gaosiga o vaega faʻavae ma vaega faʻainisinia, e pei o le felauaiga o suauu. O le faia o vaega mama faʻatasi ai ma paipa uʻamea e le mafai ona faʻaleleia le faʻaogaina o meafaitino, faʻafaigofie le gaosiga o mea, faʻasaoina mea ma taimi faʻagaioiga, e pei o le taʻavale mama, seti jack, ma isi, lea na faʻaaogaina lautele i le gaosiga o paipa. Alloy seamless paipa uamea o se mea taua tele mo auupega masani eseese, ma le paelo, paelo, ma isi e tatau ona faia i le paipa uamea. E le gata i lea, pe a oʻo i le vaega o le mama i totonu poʻo fafo o le radial pressure, o le malosi e tutusa lelei. O le mea lea, o le tele o paipa u'amea lapotopoto e lapotopoto.
