Kev soj ntsuam ntawm National Standard Parameters ntawm U-bolt
Oct 12, 2022
Thaum nws los txog rau U-bolts, feem ntau cov neeg yuav tsum paub zoo txog lawv.U-bolt, tseem hu ua U-clamp. Ib lub bolt feem ntau siv hauv cov yeeb nkab installation los kho cov yeeb nkab. Lub bolt yog U-puab. Siv los txuas ob lub firmware. Tsis hais ntau, Xiaorui yuav qhia U bolt qauv rau koj ua tib zoo.
Basic Introduction ntawm U-bolt:
1. Cov yam ntxwv tsis zoo, khoov rau lub zog, kev cuam tshuam nyuaj, lub zog tensile, qhov kub ua haujlwm thiab cov xim muaj kev txiav txim siab raws li kev siv ib puag ncig.
2. Cov khoom siv feem ntau yog carbon steel, galvanized steel thiab stainless hlau. Cov khoom siv stainless hlau muaj xws li 304, 321, 304L, 316, 316L, 317, 317L thiab 310S.
3. National standard rauU-bolts: JB/ZQ4321-1998.
Khoom siv: U-bolts muab faib ua hlau bolts, uas yog, carbon steel bolts thiab stainless hlau bolts. Stainless hlau muaj xws li stainless hlau SUS201 thiab stainless hlau SUS304.
Specification ntawm U-bolt
Ua ntej, cov xov tshwj xeeb yuav tsum raug cim, thiab tom qab ntawd sab nraud ntawm cov yeeb nkab yuav tsum tau clamped.
Piv txwv ntawm tus qauv cim rau U-bolts
Cov cim ntawm U-bolts rau kho cov kav dej nrog OD D0=25mm;
U-bolt 25 JB/ZQ 4321-97
Cov cim ntawm U-shaped bolts nrog galvanized nto rau kho cov kav dej nrog cov kab sab nraud D0=25mm;
U-bolt 25 Zn JB/ZQ 4321-97
Qee cov qauv kev qhia tshwj xeeb ntawm stainless hlau U-bolts:
M6*22 27 34 42 48 60 76 90 114
M8*22 27 34 42 48 60 76 90 114 135 161

M16*60 76 90 114 135 161 220 275 328
Lwm cov qauv txheej txheem ntawm U-bolt:
1. Xauv lub hauv paus ntsiab lus ntawm stainless hlau U-bolt: tshem tawm (los yog txwv) cov txheeb ze txav ntawm cov xov khub, los yog ua rau kom qhov nyuaj ntawm cov txheeb ze txav.
2. Khoom siv ntawm stainless hlau U-bolt: 304 302 321 304L 201 667 668 316 316L
3. Kev kos npe ntawm stainless hlau U-bolt: xov specification yog 20mm, cov khoom yog 20 # steel, thiab A-hom lug bolt yog cim raws li GB825M20
4. Daim ntawv thov ntawm stainless hlau U-bolt: stainless hlau U-bolt feem ntau yog siv rau installation thiab fixation. Nws feem ntau yog siv rau hauv cov yeeb nkab kho, hlua hlua kho thiab lwm lub sijhawm.
5. Kev kho deg ntawm stainless hlau U-bolt: liab qab lub cev lossis galvanization yuav tsum tau ua raws li cov duab kos kom zoo.
Yuav ua li cas xaiv lub bolt qib
1. [Los ntawm qhov kev xav ntawm cov khoom siv raw]: cov bolts muaj zog yog ua los ntawm cov ntaub ntawv muaj zog. Cov ntsia hlau, txiv ntseej thiab ntxhua khaub ncaws ntawm lub zog siab bolts yog ua los ntawm cov hlau muaj zog, feem ntau siv raws li No. 45 steel, 40 boron steel thiab 20 manganese titanium boron steel. Ordinary bolts feem ntau yog ua los ntawm Q235 steel.
2. [Los ntawm qib zog]: cov bolts muaj zog tau siv ntau dua. Ob qib zog, 8.8s thiab 10.9s, feem ntau yog siv, feem ntau yog 10.9. Lub zog ntawm cov bolts zoo tib yam yuav tsum tsawg, feem ntau 4.4, 4.8, 5.6 thiab 8.8.
3. [Los ntawm cov yam ntxwv kev ntxhov siab]: lub zog muaj zog bolts exert pretension thiab xa sab nraud quab yuam los ntawm kev sib txhuam. Ordinary bolt kev twb kev txuas kis shear quab yuam los ntawm bolt pas nrig shear kuj thiab lub qhov phab ntsa siab bearing. Lub pretension generated thaum zawm cov txiv ntoo yog heev me me, thiab nws tej yam yuav raug ignored. Ntxiv nrog rau cov khoom siv siab zog, cov bolts muaj zog kuj tseem ua rau lub zog loj ua ntej ntawm lub ntsia liaj qhov rooj, uas ua rau cov tswv cuab sib txuas ua kom muaj zog extrusion, kom muaj kev sib txhuam loj loj perpendicular rau cov ntsia hlau kev taw qhia. Tsis tas li ntawd, qhov ua ntej nro, tiv thaiv plam coefficient thiab steel hom ncaj qha cuam tshuam rau cov kabmob muaj peev xwm ntawm cov bolts muaj zog.
4. [Los ntawm qhov kev xav ntawm kev siv]: Lub zog muaj zog bolts feem ntau yog siv los txuas cov khoom tseem ceeb ntawm cov qauv hauv tsev. Ordinary bolts tuaj yeem rov qab siv tau, thaum lub zog muaj zog bolts tsis tuaj yeem rov qab siv dua. Lub zog muaj zog bolts feem ntau yog siv rau kev sib txuas mus tas li.
Rau Jinrui, txawm hais tias koj yog tus neeg siv khoom nrawm / tus neeg muag khoom / tus muag khoom, koj tuaj yeem mus saib lub vev xaib ntawm Jinrui: www.jinruibolt.com
Ib feem ntawm Jinrui cov khoom tso tawm Jiangsu Jinrui Hlau Khoom Co., Ltd. yog lub hauv paus tsim ntawm Shanghai Jinrui txheem qhov chaw. Lub Hoobkas npog thaj tsam ntawm ntau tshaj 20000 square metres, nrog rau kev sau npe peev ntawm 50 lab yuan, tag nrho cov peev ntawm ntau tshaj 100 lab yuan, thiab txhua xyoo tso zis ntau tshaj 20000 tons.

Fastener ntsig txog cov khoom tsis yog tus qauv Cov hlau kos duab cog nyob rau hauv Jinrui Tuam Txhab kuj muab cov kev pabcuam xws li kev kos duab zoo, kos duab ntxhib thiab spheroidizing ntawm cov hlua hlau, thiab cov khoom siv tiav hlau rods ntawm ntau lub tsev nto moo steel mills. Ua raws li kev lag luam lub tswv yim ntawm "pioneering thiab innovating, nrhiav kev ua tau zoo", Jinrui tau ua tiav ntau hom kev siv lub taub hau thiab tsim cov cav tov, xov dov cav tov, txiv ntseej tshuab, kub taub hau thiab dov tshuab, lathes, loj kub taub hau tshuab thiab lawv cov kev ntsuam xyuas. cov khoom siv, xws li magnetic particle flaw detectors, metallographic analyzers, ntsev tsuag tshuaj ntsuam cov cav tov, ncaj qha nyeem spectrometers thiab kho qhov muag tshuaj ntsuam tshuab, tensile machines, Vickers hardness meters, Rockwell hardness meters, thiab lwm yam., thiab tau teem ib tug ywj siab tshawb fawb thiab kev loj hlob departments, Nws tuaj yeem tsim txhua yam ntawm cov khoom siv zoo xws li GB, DIN, ANSI, JIS thiab ISO thoob ntiaj teb cov qauv. Cov khoom siv dav siv hauv roj av, tshuaj lom neeg kev lag luam, boiler, cua zog tsim, kev loj guardrail board, elevator qhia rail, machinery manufacturing, tsim kho qhov chaw, nws pib qhov chaw, khoom kho mob thiab lwm yam kev lag luam. Jinrui tau tsim muaj zog txij li thaum nws tsim. Nws koom ua ke qhov zoo ntawm txhua lub tuam txhab, ua tib zoo tsim thiab nruj me ntsis xaiv cov ntaub ntawv los ua kom cov khoom ruaj khov, thiab tau txais kev qhuas los ntawm feem coob ntawm cov neeg siv. Jinrui yeej lub ISO9001: 2000 thoob ntiaj teb zoo system ntawv pov thawj nyob rau hauv 2001, tshwj xeeb cov cuab yeej tsim daim ntawv tso cai nyob rau hauv 2010, thiab TS16949 automobile zoo tswj system ntawv pov thawj nyob rau hauv 2012. Cov neeg Insurance tuam txhab ntawm Tuam Tshoj underwrites lub "Tag nrho cov khoom Liability Insurance" rau nws cov khoom. kom ntseeg tau tias txhua tus ntsia hlau tuaj yeem siv nrog kev ntseeg siab, kev txiav txim siab, thiab kev thaj yeeb ntawm lub siab! Txawm tias tam sim no lossis yav tom ntej, Jinrui yuav ib txwm ua raws li cov kev pabcuam tseem ceeb ntawm "kev ua haujlwm zoo ua ntej, kev tshawb fawb thiab thev naus laus zis los txhawb kev lag luam, cov neeg siv ua ntej, thiab xav txog kev pabcuam", ua tsaug rau koj nrog cov kev pabcuam zoo thiab cov khoom zoo, thiab Jinrui kuj tseem yuav dhau los ua koj tus khub ua haujlwm ntev tshaj plaws.
