4. Faiaoga galuega

Siaki valve e otometi lava ona tatala ma tapuni le tisiketi e taofia ai le tafe i tua e ala i le tafe.

5. Fa'atatau valve talafeagai ae le gata i:

(1)API 6D-2002(2)ASME B16.5-2003

(3)ASME B16.10-2000 (4)API 598-2004

(5)GB/T 12235-1989 (6)GB/T 12236-1989

(7)GB/T 9113.1-2000 (8)GB/T 12221-2005 (9)GB/T 13927-1992

6. Teuina & Tausiga & Fa'apipi'i & Fa'agaioiga

6.1 E tatau ona teuina le valve i totonu o le potu mago ma lelei le ea .o pito o le ala e tatau ona faʻapipiʻi i ufiufi.

6.2 Valve o loʻo i lalo o se taimi umi e teu ai e tatau ona suʻesuʻeina ma faʻamamāina e le aunoa, aemaise lava foliga nofoa e puipuia ai le faaleagaina, ma o le nofoa nofoa e tatau ona ufiufi i le suauʻu e faʻafefe ai le ele.

6.3 E tatau ona siaki le makaina o alavai ina ia tausisia le fa'aoga.

6.4 E tatau ona siaki le avanoa o le valve ma le faʻamaufaʻailoga aʻo leʻi faʻapipiʻi ma aveese le palapala pe a iai.

6.5Arrow itu e tatau ona tutusa ma le itu tafe.

6.6 E tatau ona fa'apipi'i sa'o i luga o le paipa le si'i i luga o le va'a siaki tisiketi. E tatau ona fa'apipi'i fa'alava i le paipa le si'iina o le alavai siaki tisiketi faalava.

6.7 E tatau ona siaki le vibration ma e tatau ona maitauina le suiga o le mamafa o paipa e puipuia ai le aʻafiaga o le vai.

  1. E le fufusi fo'i
  2. Fa'aleagaina luga ole fa'amaufa'ailoga flange
  3. Fa'aleagaina kesi
  4. Fufusi tutusa
  5. Toe faaleleia
  6. Sui kesi fou
 

Pisa ma Tetete

  1. Valve e latalata tele ile pamu
  2. E le mautu le mamafa mamafa
  3. Toe sii i luga alatoto
  4. Aveese le fesuiaiga o le mamafa
 

8. Fa'amaonia

A maeʻa ona faʻaoga le valve, o le taimi faʻamaonia o le valve e 12 masina, ae le sili atu i le 18 masina talu ona tuʻuina atu. I le vaitaimi o le fa'amaonia, o le a tu'uina atu e le kamupani gaosi le auaunaga toe fa'aleleia po'o vaega fa'aagaga e aunoa ma se totogi mo le fa'aleagaina ona o meafaitino, gaosiga po'o le fa'aleagaina pe a sa'o le fa'agaioiga.
