Yuav ua li cas laij cov kev tso siab hauv 316 ss seamless hlab?

316 Stainless hlau seamless hlab yog dav siv nyob rau hauv high {1} {} Lub zog cua sov, thiab cov tshuaj tua hluav taws xob, thiab cov roj ntsha ua kom tiav li cov kua dej ntws los ntawm lub raj.
Kab lus no qhia txog yuav ua li cas los suav kev ua tiav cov tub sab, muab cov ntaub ntawv hnyav, muab cov ntaub ntawv hnyav hs, thiab cov lus teb rau cov lus nug yuav khoom.

1. Dab tsi yog lub siab poob thiab vim li cas nws tseem ceeb?
Lub siab poob rau kev poob kua dej siab vim kev sib txhuam ntawm cov kua thiab sab hauv ntawm lub raj, ntxiv rau qhov poob qis los ntawm cov fittings, khoov, thiab qub.
Siab dhau lub siab poob txhais tau tias lub system yuav tsum tau tso cov hluav taws xob ntau dua thiab muaj peev xwm txo cov txheej txheem txuag.
316 Stainless hlau txoj kev ua kom zoo sab hauv thiab zoo nkauj corrosion ua rau nws zoo tagnrho rau kev txo cov txheej txheem ua kom tawg, tshwj xeeb yog thaum sib piv nrog cov hlau lossis yas tubing.

 

Dab tsi yog yam cuam tshuam kev ntxhov siab poob feem ntau?
Flow nrawm, raj ntawm txoj kab uas duav, ntev, thiab kua dej viscosity. Nce cov raj uas hla lossis cov chaw ua kom tiav qhov ua tiav kom txo qis poob.

 

Dab tsi yog qhov siab tshaj plaws siab ntsuam xyuas rau 316 ss seamless hlab?
Nyob ntawm phab ntsa tuab - rau 1 "od × 3 ua tau ntawm qhov kub thiab txias (ASME B31.3 siv).

 

2. Cov Qauv Los xam cov kev tso siab siab hauv 316 SS Seamless Tubes

Lub siab poob rau ib qho ntev (Δp / l) rau tag nrho tsim kev ntws hauv lub raj ncaj feem ntau tau xam los ntawmDarcy-WeisBach Kab sib npaug:
