ASTM A501 / A501M- 14 kub} kub}}} tsim cov pa roj welded thiab seamless carbonCov Qauv Hlau Txav
ASTM A501Npog dub thiab kub - dipped galvanized kub {} Cov duab sib txawv, lossis cov tuam tsev, thiab rau cov qauv kev tsim qauv.
Lo lus hollow cov teeb tsa (HSS) yog hais txog siab siab- lub zog welding steel tubing siv thiab lwm cov qauv thiab ntau yam khoom tsim khoom. Nws yog tsim nyob rau hauv puag ncig, xwmfab thiab duab dhos thiab ntau yam ntawm cov ntau thiab tsawg rau ASTM A500, A501, A1085, A1065 specifications.
Qhov zoo ntawm hss tubings:
Lub zog siab - rau - qhov hnyav} qhov hnyav. Piv
HSS feem ntau yog cov tswv cuab kev lag luam tshaj plaws vim nws cov qauv kev teeb tsa. HSS muaj cov radii siab ntawm Gyration txog ob qho tib leeg muab cov kev ua tau zoo dua thiab tseem ceeb nqi.
Kev Thov Kom Zoo Nkauj
HSS yog feem ntau nyiam kev kos duab vim yog lawv cov tog kom huv, sib npaug, thiab kaw cov tshooj zoo tshaj plaws thaum ua rau cov qauv tsim nyog.
Tsawg thaj chaw rau txheej txheej
Shangular (suav nrog square) hss muaj kwv yees li ob - peb feem ntau ntawm thaj chaw qhib ntawm muaj peev xwm sib piv. Qhov no txhais tau tias tsawg dua qhov kev npaj, tsawg dua cov khoom siv xim, thiab ua haujlwm, thiab txo cov khoom qab zib uas tua hluav taws.
Ntu kaw
Cov ntu kaw tau zoo dua rau kev tiv thaiv torsional loads. Tsis tas li ntawd, qhov uas huv yog qhov yuav tsum tau ua rau kev ua zaub mov noj thiab lwm cov chaw huv, yog qhov kev xaiv zoo me me los sib sau cov hmoov av thiab cov khib nyiab.
