Ib tus kws tshaj lij cov lus qhia rau kev xaiv txoj cai steel raj

Tus engineer muaj ntau txoj kev xaiv thaum nws los xaiv lub zoo tagnrho steel raj rau txhua daim ntawv thov. Qib 304 thiab 316 stainless hlau tubing yog feem ntau siv. Txawm li cas los xij, ASTM kuj muab cov engineers nrog cov kev daws teeb meem zoo tshaj plaws rau lawv cov ntawv thov. Los ntawm kev ua raws li cov lus qhia tshwj xeeb, nws ua tau raws li cov hom phiaj nyiaj txiag thaum tseem muab qhov kev ua tau zoo tshaj plaws ntawm lub neej ntawm cov khoom.

Seb yuav xaiv seamless los yog welded
Thaum xaiv cov khoom siv raj, nws yog ib qho tseem ceeb kom paub seb nws yuav tsum seamless los yog welded. Seamless 304 stainless hlau tubing yog tsim los ntawm cov khoom siv zoo. Seamless raj yog tsim los ntawm extrusion, kub shearing txheej txheem, los yog rotational piercing, ib tug internal tearing txheej txheem. Seamless raj feem ntau muab rau cov phab ntsa tuab kom lawv tuaj yeem tiv taus qhov kub siab.
Lub welded raj yog tsim los ntawm dov ib tug ntev ntawm steel sawb rau hauv lub tog raj kheej, ces cua sov thiab forging cov npoo ua ke los tsim ib lub raj. Nws kuj tseem pheej yig dua thiab muaj sij hawm luv luv.

ECONOMIC CONSIDERATIONS
Cov nqi sib txawv heev nyob ntawm seb qhov ntau npaum li cas yuav, muaj thiab OD-rau-phab ntsa piv. Kev xa khoom thiab kev thov ntawm cov khoom siv txawv teb chaws tau thawb tus nqi thoob plaws qhov chaw. Nickel, tooj liab thiab molybdenum tus nqi tau nce thiab poob qis heev nyob rau xyoo tas los no, nrog rau kev cuam tshuam tseem ceeb ntawm cov nqi steel raj. Yog li ntawd, yuav tsum tau saib xyuas ntxiv thaum teeb tsa kev siv nyiaj mus sij hawm ntev rau cov alloyed siab dua xws li TP 304, TP 316, cupro-nickel thiab alloys uas muaj 6% molybdenum. Tsis tshua muaj npib tsib xee alloys xws li Admiralty Brass, TP 439 thiab super ferritics yog ruaj khov thiab kwv yees.
