Cov lus qhia rau kev siv cov kav dej steel

Cov lus qhia rau kev siv cov kav hlau siv hlau tsuas yog suav nrog cov hauv qab no:

Cov lus qhia rau dabtsi yog khoov cov kav hlau: steel yeeb nkab khoov yog ib qho txheej txheem hlau ua kom tiav cov haujlwm uas yuav tsum tau ua kom tau txais lub kaum sab xis. Kev siv cov txheej txheem no suav nrog phau ntawv dabtsi yog los ntawm phau ntawv dabtsi yog khoov, kev siv tshuab los khoov, nplaim taws txiav dabtsi yog khoov thiab txias dabtsi yog khoov. Select appropriate bending methods and tools to ensure that the steel pipe has good plasticity and toughness, and conduct quality inspections on the bent steel pipes to ensure that they meet the use requirements.

Cov lus qhia rau ntsug vuam: views vuam yog hais txog kev sib koom ua ke los ntawm sab saum toj mus rau sab saum toj, nrog ib txoj hauj lwm vuam nrog lub weld kaum ntawm 90 degree lossis 270 degree. Thaum lub sij hawm vuam ntsug, molten cov tee dej hlau thiab molten tee muaj qhov poob vim muaj tshwm sim, thiab muaj zog tsis tshua muaj tshwm sim, thiab tsis muaj zog rau slag suav nrog. Thaum vuam, kev saib xyuas yuav tsum tau them rau electrode lub kaum thiab kev ua hauj lwm thaum lub sij hawm vuam kiv kom ntseeg tau tias vuam muag.

Kev teeb tsa thiab siv cov epoxy coated steel kav hlau: Zam thaum txhim kho cov roj sib tsoo hlau txiav kom tsis txhob muaj cov txheej txheem yas lossis ntau dua extrusion. Thaum kev ua xov threase, lathes lossis los kho tshuab, yeeb nkab dabtsi yog ua kom tsis txhob muaj kev puas tsuaj rau cov yas txheej. Hais txog txoj kev sib txuas, kav dej nrog txoj kab uas hla ntawm 15 hli {mm tuaj yeem txuas nrog lub cheeb ntawm 100 hli lossis ntau dua yuav tsum txuas los ntawm grooves lossis flanges. Cov ntsiab lus tseem ceeb ntawm cov xa hluav taws xob tsim qauv: thaum tsim qauv hluav taws xob, nws yog qhov tsim nyog rau kev xaiv, nrog rau cov khoom siv tsim nyog, suav nrog cov phiaj xwm loj, teeb meem nrog cov raj xa hluav taws xob. Lub raj xa dej installation ntawm lub tshuab cua txias yuav tsum ua raws cov ntsiab lus tseem ceeb, kev txhawb nqa thiab kev ua haujlwm ruaj khov thiab muaj txiaj ntsig ntawm cov kab ke.
