1. Tus tsim kub thiab lub zog ntawm lub thawv;

2. Tus qauv sib txuas rau li qub, fittings, kub, thiab theem gauges txuas nrog nws;

3. Tus cawv ntawm thermal kev ntxhov siab ntawm flange ntawm kev sib txuas cov yeeb nkab hauv cov txheej txheem pipelines (siab-kub, thermal pipelines);

4. Cov txheej txheem thiab kev ua haujlwm nruab nrab cov yam ntxwv:

Rau cov ntim hauv qab cov chaw nqus dej, thaum lub tshuab nqus tsev yog tsawg dua 600mmHG, qhov siab ntsuas ntawm cov flange yuav tsum tsis pub tsawg tshaj 0.6mpa; Thaum lub tshuab nqus tsev yog (600mmHg ~ 759mmHG), theem siab ntawm kev sib txuas flange yuav tsum tsis tsawg tshaj li 1.0MPA;

Rau cov thawv muaj cov phom sij tawg thiab nruab nrab kev phom sij txaus ntshai, cov qib siab theem ntawm lub thawv sib txuas yuav tsum tsis pub tsawg tshaj 1.6mpa;

Rau cov thawv ntim muaj cov kev phom sij heev thiab zoo li muaj ntau tshaj tawm cov xov xwm txuas ntxiv, cov kev ntaus pob zeb heev ntawm lub thawv flange yuav tsum tsis qis dua 2.0mpa.

Nws yuav tsum raug sau tseg tias thaum cov khoom sib khi ntawm cov thawv flawe yog xaiv rau sab saum toj thiab Tenon cov thawv uas yuav tsum tau xaiv ua qhov sib dhos; Cov yeeb nkab txuas nyob rau hauv qab ntawm lub thawv yuav tsum siv ib tug tsa lossis Tenon ntsib Flange Flange.
