ASTM A193 Qib B7 Kev Tshawb Nrhiav Bolts
ASTM A193 Qib B7 Statch Bolts yog high-zog, cov zog ruaj khov fasteners tsim raws li cov neeg Asmeskas haiv neeg rau kev sim thiab cov ntaub ntawv (ASTM) A193 tus qauv.
ASTM A193 Qib B7 Statch Bolts yog high-zog, cov zog ruaj khov fasteners tsim raws li cov neeg Asmeskas haiv neeg rau kev sim thiab cov ntaub ntawv (ASTM) A193 tus qauv. Lawv tau ua los ntawm alloy steel, quenched thiab tempered, thiab muaj cov kws kho tshuab zoo nkauj. Lawv tau siv dav hauv ntau cov cuab yeej siv thiab cov txheej txheem sib txuas uas yuav tsum tau ua kom muaj cov khoom siv siab thiab kub, xws li cov roj av roj av, hluav taws xob siab, pipeline flange sib txuas, thiab lwm yam.

Qhov tsawg kawg nkaus elongation ntawm astm A193 Qib B7 Stud Bolts yog 16%. Ib qho kev sib tw elongation uas tau muaj qee cov yeeb yaj kiab muaj qee qhov muaj peev xwm ua kom muaj peev xwm ua tau zoo nkauj, uas tseem ceeb heev thaum raug cov khoom thauj khoom lossis cov khoom siv tsis sib xws. Nws tuaj yeem hloov kho cov kev ntxhov siab los ntawm cov yas deformation thiab tiv thaiv cov ntsia liaj qhov rooj los ntawm kev rhuav tshem tam sim ntawd.
Daim Ntawv Thov Kev Pab Cuam
Roj thiab Roj Kev Lag Luam
Hauv kev ua kom huv, muaj ntau cov cuab yeej xws li distillation yees, thiab lwm yam kev hloov pauv cua sov, thiab lwm yam. ASTM A193 Qib B7 Statch Bolts tuaj yeem tiv thaiv cov xwm txheej no thiab xyuas kom meej tias cov khoom siv hauv ntau yam khoom siv tau sib txuas nrog tiv thaiv kom tsis txhob muaj qhov xau.
Kev lag luam fais fab
Thermal fais fab nroj tsuag: thaum lub zog hluav taws xob cov txheej txheem, cov khoom siv xws li cov roj, tshuab, thiab cov tshuab hluav taws xob yuav tsum tau ua haujlwm hauv qab qhov kub thiab siab siab. Kev siv cov pob tw feem ntau yog siv nyob rau hauv cov khoom tseem ceeb ntawm cov khoom siv boiler, cov khoom siv boiler thiab kho kom zoo dua li lub hauv paus, ntxiv rau lub hauv paus txhim kho lub tshuab luam yeeb thiab cov tshuab hluav taws xob.
Tshuaj Kev Lag Luam
Hauv kev tsim cov tshuaj lom neeg, cov tshuaj uas muaj tshuaj lom li yog ib qho ntawm cov khoom tseem ceeb, thiab tshuaj lom neeg feem ntau yuav tsum muaj nyob rau hauv kub siab, kev tawm siab thiab muaj kev tawm siab. ASTM A193 Qib B7 Statch Bolts tuaj yeem siv cov kev ua haujlwm ntawm lub tog raj kheej, cov yeeb nkab thiab lwm yam kev nyab xeeb kev nyab xeeb tshwm sim los ntawm cov kev sib txuas ntawm cov khoom sib txuas lossis dej xau.
