Kev piav qhia ntau lawm
Bolts ua los ntawm high-strength steel los yog xav tau ib tug tseem ceeb ua ntej zawm quab yuam yuav raug xa mus rau raws li high-strength bolts. Lub zog muaj zog bolts feem ntau yog siv rau kev sib txuas txuas hniav, steel rails, high-voltage thiab ultra-high voltage khoom. Qhov tawg ntawm hom ntsia liaj qhov rooj no feem ntau yog cov pob txha tawg. Lub zog muaj zog bolts siv rau cov cuab yeej siv siab ultra-siab xav tau qhov tseem ceeb prestressing los xyuas kom meej lub ntim ntawm lub ntim.
Qee lub tswv yim hais txog lub zog muaj zog bolts
Raws li cov kev cai ntawm bolt kev ua tau zoo qib hauv 8.8 lossis siab dua, hu ua bolts muaj zog. Raws li lub Peb Hlis 2020, Tuam Tshoj tus qauv hauv tebchaws tsuas yog teev rau M68. Rau qhov loj me specifications, tshwj xeeb tshaj yog qhov ntev ntawm lub ntsia liaj qhov rooj nws tus kheej 10 ~ 15 lub sij hawm ntawm high-strength bolts, tiav lawm cov khoom yog tsis tshua muaj, ib tug me me ntawm domestic manufacturers nyob rau hauv Tuam Tshoj yuav customized. [1-2] [3] bolt siab zog thiab zoo tib yam ntsia liaj qhov rooj sib txawv: siab-lub zog ntsia liaj qhov rooj muaj peev xwm tiv taus lub load dua li cov ntsiab lus ntawm cov ntsia liaj qhov rooj zoo tib yam kom ntau dua. Cov khoom siv ntawm cov bolts zoo tib yam yog ua los ntawm Q235 (A3). Lub zog muaj zog bolt khoom 35 # steel lossis lwm yam khoom siv zoo, ua tom qab kev kho cua sov, txhim kho lub zog.
