6. Cov hnav zoo tsis kam rau ib puag ncig hnav: Hauv qee kis, cov coj tsis kam ntawm ASTM A350 ua rau nws zoo tagnrho rau kev tsim cov kav dej thiab cov fittings, tshwj xeeb tshaj yog hauv cov kua dej ntws.

7. Ntau yam ntawm cov ntawv thov ntau yam kev siv: cov khoom siv tau dav siv hauv cov roj, roj, cov khoom siv tshuaj lom, cov yeeb nkab fittings, li qub.

ASTM A350 Cov Chaw Thov Daim Ntawv Thov:

1. Cov roj thiab roj kev lag luam:

Lified nkev (lng) Cov Khoom Siv: rau cov kav dej tsis tshua muaj siab, thiab lwm yam, thiab lwm yam.}}}} C).

Roj thiab roj pipelines nyob rau hauv cov cheeb tsam txias: xws li arctic thauj cov tshuab, uas yuav tsum muaj cov ntaub ntawv yuav tsum nyob ntawm qhov chaw kub tsawg.

2. Siab rau lub nkoj thiab lub taub roj

Tsawg qhov kub kub cia: xws li kua nitrogen cia, oxygen thiab cov khoom siv tawv me, thiab ntsuas kub thiab kub kom muaj kev ntsuas.

Siv khoom siv tshuaj: Forgings rau kev tiv thaiv qhov kub tsawg lossis sib cais.

3. Flange, li qub thiab cov yeeb nkab fittings

Kev ntxhov siab siab txuas: xws li cov yeeb nkab flanges thiab li qub, siv lf 1 / lf 2 cov khoom siv los tiv thaiv kev pheej hmoo ntawm cov dej xau ib puag ncig tsawg.

4. Daim ntawv thov nyob hauv ib puag ncig tshwj xeeb

Cov nkoj thiab cov pa hluav taws xob tua hluav taws: qhov ntsuas kub uas tsawg hluav taws xob hauv cov tsheb nqaj hlau long.

Cov kab ke tub yees: siab qhov chaw ntawm cov khoom siv tub yees.
