Fa'aaliga/Uiga
• Fa'amau fa'amau o paipa fa'aoga e sui ai le ala o se paipa (tulima), fa'aitiitia/fa'ateleina le lapo'a o paipa (fa'aitiitiga), lala (tees, cross) po'o le tauaso o se paipa (butt weld cap)
• Fa'apipi'i Buttweld e maua i le tele o foliga (tulima, tees, reducers, crosses, caps, stub ends), meafaitino togi (carbon, high-yield carbon, low-alloy, stainless, duplex, ma nickel alloys),
ma fua (2 i le 24 inisi i le faʻaogaina e le faʻaogaina, ma faʻapipiʻiina mo le tele o paipa).
• O faʻamatalaga autu mo mea faʻapipiʻi buttweld o le ASME B16.9 (carbon and alloy fittings) ma le MSS SP 43 (lea e tuʻufaʻatasia ai le ASME B16.9 mo mea faʻapipiʻi uʻamea, duplex, ma nickel alloy BW fittings).
• E pei lava ona fa'atauina le paipa mai le Fa'amatalaga 10 i le Fa'amatalaga 160, e fa'atau atu fo'i mea fa'apipi'i paipa i le auala lava e tasi.
O mea faʻapipiʻi faʻapipiʻi faʻapipiʻi e sili atu ona taatele i uʻamea uʻamea ona o le faʻaogaina o tau. Sch 10S, SCH40SSS mea faʻapipiʻie sili atu ona taatele i uamea uamea uelo fa'apipi'i.
O mea masani mo mea faʻapipiʻi faʻapipiʻi o le A234 WPB (A & C o loʻo avanoa foi), High Yield Carbon Steel, Stainless Steel 304 ma le 316 ma Nickel Alloys.
• O mea fa'apipi'i fa'apipi'i i totonu o le uamea kaponi ma le uamea u'amea o vaega tu'ufa'atasia ia e mafai ai ona fa'apipi'iina alatoto,
paipa ma meafaigaluega i luga ole faiga paipa. O mea fa'apipi'i e fa'aigoaina e fa'amalo ai au paipa i so'o se faiga paipa ma fa'atagaina:
1. Suia le itu o le tafe i se faiga paipa
2. Feso'ota'i po'o paipa fa'atasi ma meafaigaluega
3. Tuuina atu lala, avanoa ma alu ese mo meafaigaluega fesoasoani

Fesili & Tali ( Q&A )
Q: Na fesili le tagata faʻatau mo mea faʻapipiʻi faʻapipiʻi i le A105:
A: Ole mea masani faʻapipiʻi faʻapipiʻi faʻapipiʻi carbon steel ole A234WPB. E tutusa ma le A105 flanges, peitaʻi e leai se mea e pei o le A105 poʻo le A106 faʻapipiʻi faʻapipiʻi.
A106 Gr.B e mo le tulaga paipa. O mea faʻapipiʻi A234WPB e faia mai paipa A106GR.B. O le A105 o se mea mai le Pa na fa'atauina e avea ma mea'ai maualuga po'o Flange
F: O lo'o mana'omia e tagata fa'atau mea fa'apipi'i fa'apipi'i fa'apipi'i:
A: O se manatu sese foi lea talu ai o loʻo maua flanges i le A105 ma le A105 N, lea o le N e tu mo le masani.
Ae ui i lea, e leai se mea e pei o A234WPBN. Fa'ato'aga fa'ameamea a latou mea fa'apipi'i fa'apipi'i na manatu e fa'aa'oa'oina le fa'agasologa o le vevela na faia, ae maise mo tulilima ma Tees.
Tagata fa'atau e mana'omia ni mea fa'apipi'i "fa'asa'o" e tatau ona talosagaina ni fa'apipi'i WPL6 e maualuga le fua ma fa'amautu e pei o se faiga masani.
F: Ua galo i le tagata fa'atau le ta'ua o le faasologa o paipa:
A: Buttweld fittings o loʻo faʻatau atu e tusa ai ma le tele o paipa ae tatau ona faʻamaonia le faasologa o paipa e fetaui ma le ID o le faʻapipiʻi i le ID o le paipa. Afai e leai se fa'asologa o lo'o ta'ua, o le a tatou fa'apea e mana'omia se puipui masani.
Q; Ua galo i le tagata fa'atau le ta'ua o le uelo fa'apipi'i po'o le fa'aogaina o le fa'aogaina:
O mea fa'apipi'i uelo o lo'o maua ile fa'a-uelo fa'apea fo'i le fa'aogaina. O se u'a fa'a'au fa'a'au'au u'u uamea kaponi po'o fa'apipi'i u'amea uamea e fai i paipa su'ega ma e masani lava e sili atu le taugata.
O mea fa'apipi'i paipa e LĒ masani i lapopo'a e sili atu i le 12". O mea fa'apipi'i paipa e fa'apipi'iina i le ERW u'umea kaponi uamea po'o le paipa uamea. E maua i lapopo'a ½" i le 72" ma e sili atu le taugofie nai lomea fa'apipi'i.
F: O le a le uiga o le Short Radius (SR) poʻo le Long Radius (LR)?
A: E masani ona e faʻalogo i le tulilima SR45 poʻo le tulilima LR45. O le 45 poʻo le 90 e faʻatatau i le tulimanu o le piʻo mo le faʻapipiʻiina o le buttweld e sui ai le itu o le tafe.
O le tulilima umi (LR 90 Elbow po'o le LR 45 elbow) o le ai ai se paipa pi'o e 1.5 taimi le tele o le paipa. O lea la, o le 6 inisi LR 90 o lo'o i ai le laina fa'apipi'i e 1.5 x le tele o paipa.
Ole tulilima pu'upu'u (SR45 po'o le SR90) o lo'o i ai se pi'o paipa e tutusa ma le tele o le fa'apipi'i, o lona uiga o le 6" SR 45 o lo'o i ai le laina fa'apipi'i e 6" le tele o paipa.
Q: O le a le 3R poʻo le 3D e fetaui lelei paipa?
A: Muamua, o faaupuga 3R poʻo le 3D e faʻaoga tutusa. O le tulilima uelo fa'a 3R o lo'o i ai lona laina pi'o e fa'atoluina le lapo'a o le paipa. O le tulilima 3R e tutusa ma le 3D Elbows
