Yuav ua li cas cuam tshuam rau sab nraud txoj kab uas hla ntawm square thiab rectangular raj?

• Txoj kev qhib pwm rau cov kab loj-ntev thiab cov kab plaub hau yog ib qho tseem ceeb hauv kev tswj cov txheej txheem tolerances ntawm lawv cov diameters. Rau longitudinally dov loj-inch square thiab rectangular raj, lub sab nraud txoj kab uas hla yuav ncav cuag li ntawm 1%, thaum rau oblique dov loj-inch square thiab rectangular raj, lub siab sab nraud txoj kab uas hla yog xyuas kom meej nyob rau hauv 0.5 %.
• Kev tswj cov txheej txheem ntau lawm cuam tshuam rau txoj kab uas hla qhov tseeb ntawm cov kab loj-inch square thiab cov kab plaub. Kev tswj xyuas kev txiav txim siab ntawm txoj kab uas hla ntawm qhov loj-inch square thiab rectangular tube sizing machine nyob ntawm qhov ruaj khov ntawm cov kub dov kub thiab kub. Nrog rau qhov nce ntawm qhov kub dov kub ntawm qhov loj-inch square thiab rectangular raj, muaj ntau dua shrinkage tom qab dov, uas tuaj yeem yooj yim tshaj li txoj kab uas hla, ua rau muaj qhov tsis zoo sib txawv.
• Hloov pauv, qhov kub tsis kub dov yuav ua rau ntau tshaj qhov zoo sib txawv, ua rau muaj qhov tsis xws luag. Yog li ntawd, kev hloov pauv mus rau qhov txuas txuas ntxiv ntawm cov kab loj-inch square thiab cov kab plaub hau yuav tsum tau ua tas li raws li cov lus qhia ntawm cov pwm qhib, qhov loj ntawm qhov loj-inch square thiab rectangular raj, qhov kub thiab txias, thiab qhov tshwm sim ntawm kev puas tsuaj ntawm cov cuab yeej.
