Qhov sib txawv tseem ceeb ntawm cov raj thiab cov kav dej hauv cov qauv

Cov duab sib txawv

Covcevmuaj lub qhov ncauj square tube lub qhov ncauj, lub raj lub qhov ncauj, thiab ib puag ncig zoo li; cov kav dej yog tag nrho puag ncig;

txawvroughness

Cov raj yog nruj, nrog rau cov raj hloov tau ua los ntawm tooj liab thiab tooj dag; cov kav dej yog nruj thiab resistant rau dabtsi yog khoov;

Kev faib tawm txawv

Tubes raws lisab nraud txoj kab uas hla thiab phab ntsa thickness; yeeb nkab raws li phab ntsa thickness code yeeb nkab teem caij thiab nominal txoj kab uas hla (European Standard) = lub teb chaws yeeb nkab loj (American Standard)

Kev siv ib puag ncig txawv

Cov raj siv thaum xav tau cov raj me me. 10 nti raj yog tsawg. Cov kav dej yog siv thaum xav tau cov raj loj loj. 10 nti raj yog ntau, xws li ib nrab-inch mus rau ob peb ko taw.

Kev xav kom pom tseeb sib txawv

Lub raj ua tib zoo saib xyuas qhov tseeb ntawm txoj kab uas hla sab nraud, vim tias nws cuam tshuam nrog lub siab, uas yog siv rau lub raj cua txias, lub raj cua kub exchanger, thiab boiler raj; cov yeeb nkab them mloog mus rau phab ntsa thickness, vim hais tias cov yeeb nkab feem ntau thauj cov kua thiab yuav tsum tau muaj peev xwm sab hauv siab;

Phab ntsa thickness txawv

Phab ntsa thickness theem ntawm lub raj yog nce los ntawm 1 qib, thiab phab ntsa thickness yog nce los ntawm 1 hli los yog 2 hli, thiab qhov nce yog tsau. Phab ntsa thickness ntawm cov yeeb nkab yog qhia los ntawm lub sijhawm. Kev sib raug zoo ntawm qhov tseem ceeb ntawm ntau theem tsis paub meej. Kev sib txuas ntawm cov yeeb nkab yog siv zog ua haujlwm thiab tuaj yeem welded. Nws tseem tuaj yeem txuas nrog xov lossis flange.
