O le fa'afeso'ota'i o paipa ma mea fa'apipi'i (300-999 psi) e mana'omia ai le Vasega 300 auvai filo.O filo o lo'o i totonu o le flange o lo'o fa'apipi'i i filo i luga o se paipa e aunoa ma se uelo.E masani lava, o foliga o nei flanges e sii i luga, mafolafola, poʻo le RTJ (tulaga mama).NPT (National Pipe Thread) ma le BSPT (British Standard Pipe Taper) o ni fa'ata'ita'iga se lua o feso'ota'iga filo.O le chromium-nickel alloy type 304 stainless steel e tete'e i le pala e mafua mai i le susu, vevela, salinity, acids, minerale, ma eleele peaty.I le faaopoopo atu i le tele o nickel nai lo le ituaiga 304 stainless steel, ituaiga 316 stainless steel o loʻo iai foʻi le molybdenum mo le sili atu ona lelei le faʻafefe.
O le atinaʻeina ma le gaosiga o faʻauʻu filo filo uamea o se faʻapitoa a le JLPV.Austenitic stainless steel, duplex steel, ma super duplex steel o mea muamua ia e faʻaaogaina e le kamupani e fai ai flanges fale gaosi oloa.I le taimi nei, o oloa a le kamupani o loʻo faʻatau atu ma le manuia i le sili atu ma le sefulu itumalo Saina ma itulagi, e aofia ai Hong Kong ma Taiwan, ma i le Iunaite Setete, Kanata, Pasila, Siamani, Peretania, Farani, ma Sasaʻe Tutotonu mo oloa e pipii i ai. Tulaga Amerika ma Europa.O tagata fa'atau i totonu ma fa'ava-o-malo e tu'ufa'atasia lo latou fa'amemelo i le lelei o oloa.
