1. Thaum xaiv cov pipeline txhawb thiab khuam khawb ncaws, kev coj ua ntawm cov raj xa dej, seb qhov ntsuas kub ua haujlwm yog insulated thiab txias, thiab cov khoom siv ntawm cov raj dej:

2. Thaum tsim cov yeeb nkab txhawb nqa thiab cov yeeb nkab pob kws clamps, cov yeeb nkab txhawb nqa thiab cov tshuab yeeb nkab yuav tsum tau siv ntau li ntau tau;

3. Welded yeeb nkab txhawb nqa thiab cov yeeb nkab dai dai rau cov hlau dua clamp-hom yeeb nkab txhawb nqa thiab cov qauv siv hluav taws xob, thiab yooj yim rau kev tsim khoom thiab cov qauv tsim kho. Yog li ntawd, tsuas yog rau cov rooj plaub hauv qab no, Welded yeeb nkab Clamps thiab cov tshuab yeeb nkab yuav tsum tau siv ntau li ntau tau;

1) Cov kav dej ua los ntawm cov hlau hlau nrog cov ntsuas kub hauv cov yeeb nkab sib npaug lossis ntau dua 400 degrees;

2) cov raj ntsuas kub tsawg;

3) Alloy Steel Kav;

4) Cov kav dej uas yuav tsum tau ua kom tsis txhob muaj kev tshem tawm thiab kho kom nquag thaum lub sijhawm ntau lawm;
