1. Kev tshuaj xyuas ntawm qhov ntev geometric thiab cov tsos ntawm cov yeeb nkab steel:
1. Steel yeeb nkab phab ntsa thickness tshuaj xyuas: micrometer, ultrasonic thickness gauge, tsis tsawg tshaj li 8 cov ntsiab lus ntawm ob qho tag nrho thiab kaw.
2. Txheeb xyuas cov kab thiab ovality ntawm cov yeeb nkab steel: caliper, vernier caliper, lub nplhaib ntsuas, ntsuas qhov siab tshaj plaws thiab qhov tsawg kawg nkaus.
3. steel yeeb nkab ntev soj ntsuam: steel daim kab xev ntsuas, phau ntawv qhia thiab ntsuas qhov ntev tsis siv neeg.
4. Steel yeeb nkab curvature soj ntsuam: kav, theem (1m), feeler gauge, nyias hlau los ntsuas qhov curvature ib meter thiab curvature ntawm tag nrho ntev.
5. Kev soj ntsuam ntawm seamless steel yeeb nkab kawg bevel kaum sab xis thiab blunt ntug: square kav thiab clamping phaj.
2. Hlau yeeb nkab nto zoo soj ntsuam:
1. Kev tshuaj xyuas qhov muag pom: teeb pom kev zoo, qauv, kev paub dhau los, cov cim, kev sib hloov steel yeeb nkab.
2. Kev sim tsis muaj kev puas tsuaj: kev kuaj ultrasonic UT, eddy tam sim no kuaj ET, sib nqus particle MT thiab sib nqus flux to testing, electromagnetic ultrasonic test, penetrant testing.
Seamless steel kav yog dav siv. General-purpose seamless steel kav yog dov los ntawm cov pa roj carbon zoo tib yam steel, uas tsis muaj hlau alloy steel los yog alloy structural steel. Lawv muaj cov zis ntau tshaj plaws thiab feem ntau yog siv los ua cov kav dej lossis cov khoom siv rau kev xa cov kua dej.
Nws tau muab rau hauv peb pawg raws li kev siv sib txawv:
a. Muab raws li tshuaj muaj pes tsawg leeg thiab txhua yam khoom;
b. Muab khoom raws li cov khoom siv kho tshuab;
c. Muab raws li hydraulic siab kuaj.
