O le fa'amatalaina sa'o o le lapo'a o se fa'aau u'amea e mana'omia le aofia ai o ni fa'auiga autu:
Tatami i fafo (OD)
Le lautele pito i fafo o le paipa uʻamea, e masani ona faʻaalia e pei o le numera numera (DN) poʻo le tele o paipa (NPS).
Lapo'a Fa'aigoa Paipa (NPS) vs. Ta'amilosaga Fa'aigoa (DN)
O le NPS o le lapo'a fa'atatau i inisi, a'o le DN o le fa'ameamea i millimita.O le sootaga o le liua e fai si faigofie: o le tau o le DN e tutusa ma le tau NPS faʻateleina i le 25.4 (mm / inisi) e faʻataʻamilo ai le taunuuga.
I le faʻatinoga, o fesoʻotaʻiga i le va o le NPS ma le DN faʻavae e faʻavae atili i luga o laulau faʻavasegaina ua faʻatuina.
Mafiafia o le Pa (WT)
Le mafiafia o le puipui paipa.Mo paipa lapopoa masani, o le mafiafia o puipui e masani ona fesootai ma le Faamatalaga o le paipa, e pei o le Faamatalaga 40 po o le Faamatalaga 80, lea o tau tetele e faailoa ai puipui mafiafia.
Umi
Le umi o se paipa uʻamea, lea e mafai ona faʻamautu pe faʻafuaseʻi, faʻalagolago i le gaosiga ma manaʻoga faʻaoga.Ole umi masani ole 6 mita ma le 12 mita.
Mea
Tulaga o meafaitino ma togi mo paipa uamea, e pei ole ASTM A106 Grade B, API 5L Grade B, ma isi.
Tulaga
Ole fua fa'atatau mo le kaponi ma le paipa uamea e masani ona mulimulita'i ile ASME B36.10M (carbon and alloy steel) ma le B36.19M (paipa uamea).
Laupapa Lapopo'a Paipa ma Laupapa Fua Mamafa (WGT)
tuʻuina atu se auala faʻapitoa e faʻamatala ai le mafiafia o le paipa i lalo o Faʻamatalaga eseese, faʻapea foʻi ma le faʻavasegaina o togi mamafa e pei o STD, XS, XXS, ma isi.
O le mafiafia o le puipui o se paipa e aafia saʻo ai le tele o totonu ma le mamafa o le paipa.E taua le mafiafia o le puipui aua e iloa ai le tele o le mamafa o totonu e mafai e le paipa ona tatalia.
Numera fa'asologa
O se auala e faʻaalia ai le mafiafia o le puipui o se paipa, e masani lava e pei o le Faʻamatalaga 40 ma le 80, e faʻatatau i le tulaga masani ma le faʻamalosia o le mafiafia o le paipa mo le lautele o fafo.
Ole fa'atatauga ole numera ole fa'asologa e fa'apea:
Ona o lo latou gafatia e tetee atu i mamafa masani, Faʻamatalaga 40 ma le Faʻasologa 80 paipa uʻamea e masani ona manaʻomia i le tele o alamanuia.Talu ai o nei paipa ua mamanuina e tetee atu i le maualuga o le mamafa, e masani ona manaʻomia i le tele o mea e faʻafetaui ai manaʻoga o pisinisi eseese.
