1. Kev tshuaj xyuas tshuaj lom neeg
Cov tshuaj muaj pes tsawg leeg ntawm high-frequency welded steel hlab muaj qhov cuam tshuam loj rau lawv cov kev ua tau zoo, yog li ntawd, kev tshuaj xyuas tshuaj muaj pes tsawg leeg yog tsim nyog. Qhov no feem ntau yog ua los ntawm kev tshuaj ntsuam xyuas tshuaj lossis kev ntsuas kev ntsuas, xws li infrared CS analyzers thiab cov ntawv nyeem ncaj qha, txhawm rau txheeb xyuas cov ntsiab lus ntawm cov ntsiab lus xws li C, S, Si, Mn, P, Cr, Mo, Ni, thiab lwm yam. nyob rau hauv lub steel tube.
2. Geometric Dimension thiab Shape Inspection
Phab ntsa Thickness Inspection: Cov cuab yeej xws li micrometers thiab thickness gauges yog siv los ntsuas cov phab ntsa thickness ntawm cov hlau hlab, kom ntseeg tau tias lawv poob nyob rau hauv cov kev cai kam rau ua.
Kev Tshuaj Xyuas Sab Nraud thiab Ovality: Cov cuab yeej zoo li calipers, vernier calipers, thiab lub nplhaib ntsuas yog siv los ntsuas cov kab sab nraud thiab ovality ntawm cov raj hlau, ntsuas lawv qhov ntsuas qhov tseeb.
Length Inspection: steel tapes thiab lwm yam cuab yeej yog siv los ntsuas qhov ntev ntawm cov hlau raj, kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua kom ruaj khov lossis ntau qhov ntev.
Khoov Kev Ntsuam Xyuas: Cov cuab yeej xws li straightedges, theem, thiab feeler gauges yog siv los ntsuas qhov khoov ib 'meter' thiab tag nrho khoov ntawm cov hlab steel, guaranteeing lawv ncaj.
End Face Bevel Angle thiab Blunt Edge Inspection: Lub kaum ntse ntse ntsuas thiab caliper daim hlau yog siv los tshuaj xyuas lub kaum sab xis ntawm lub kaum sab xis thiab blunt ntug qhov ntev ntawm cov yeeb nkab steel kawg, kom ntseeg tau tias lawv ua tau raws li qhov xav tau ntawm vuam.
3. Kev kuaj xyuas lub cev
Mechanical Performance Tests: Cov no suav nrog kev sim flattening, flare tests, dabtsi yog khoov tests, thiab hardness tests, uas yog siv los soj ntsuam cov cuab yeej ua tau zoo xws li tensile zog, yield zog, thiab elongation ntawm steel hlab.
Hydraulic los yog Pneumatic Tests: Hydraulic los yog pneumatic xeem yog ua nyob rau hauv steel hlab los xyuas lawv airtightness thiab weld zog. Qhov no yog ib kauj ruam tseem ceeb hauv kev ua kom ntseeg tau tias cov raj steel tuaj yeem tiv taus qee qhov siab sab hauv thaum siv.
4. Kev sim tsis muaj kev puas tsuaj
Kev Ntsuas Ultrasonic: Kev kuaj ultrasonic yog ua rau ntawm cov welds sab hauv thiab sab nraud thiab lub hauv paus hlau ntawm ob sab ntawm cov welds ntawm cov hlau raj txhawm rau txheeb xyuas qhov tsis xws luag xws li tawg thiab slag suav nrog.
X-ray Inspection: X-ray industrial TV soj ntsuam yog ua nyob rau hauv thiab sab nraud welds ntawm cov hlau hlab, siv cov duab ua tshuab los xyuas kom meej rhiab heev nyob rau hauv qhov tsis pom kev thiab paub meej tias weld zoo.
Eddy Current Testing: Qee zaum, eddy kev ntsuam xyuas tam sim no yuav raug siv los ua lwm txoj hauv kev kuaj hydraulic txhawm rau txheeb xyuas qhov tsis xws luag ntawm thiab nyob ze ntawm cov hlab hlau.
5. Lwm yam kev xeem
Expanding Test: Ib qho kev sim nthuav dav yog ua los ntawm submerged arc welded ncaj seam steel hlab los txhim kho lawv qhov tseeb qhov tseeb thiab txhim kho kev faib tawm ntawm kev ntxhov siab hauv cov hlab.
Magnetic Particle Inspection of Tube Ends: Magnetic particle soj ntsuam yog ua nyob rau hauv lub raj kawg ntawm cov hlau raj kom paub qhov muaj peev xwm tsis xws luag xws li tawg.
