Flange bolts yog tshem tau fasteners tsim los rau siab - kev sib txuas muaj zog, yuav tsum tau siv cov txiv ntseej. Lawv feem ntau yog siv nyob rau hauv automotive engines, hnyav machinery, thiab instrumentation. Lawv cov qauv muaj xws li ib tug integraly tsim hex taub hau, flange phaj, thiab externally threaded ncej. Raws li lub taub hau zoo, lawv tau muab faib ua tiaj tus - taub hau thiab countersunk - hom taub hau. Lub flange phaj tsim ua rau kom muaj kev sib cuag los txhim kho kev tiv thaiv -loosing kev ua tau zoo. Qee cov qauv muaj cov serrations los yog nplua - xov shafts kom haum rau kev vibration{10}} cov ntawv siv yooj yim.

Stainless hlau flange bolts VS siab zog Flange bolts

Stainless hlau flange bolts feem ntau lub hom phiaj tiv thaiv corrosion, thaum lub zog siab flange bolts tsom rau txhua yam muaj zog thiab kub tsis kam.

cov khoom
Khoom npe	Stainless hlau Flange Bolts	Siab zog Flange Bolts
Yam khoom siv	Austenitic stainless hlau: 304 (A2), 316 (A4) Martensitic stainless hlau: 410	Nruab nrab- carbon alloy steel: xws li chromium-molybdenum steel (Cr-Mo)
Qib Siab	Lub zog nruab nrab (Tensile zog kwv yees li 700-900 MPa)	Siab rau Ultra-High Strength (Tensile zog mus txog 860 MPa thiab siab dua; B7 yam tsawg kawg nkaus yog 860 MPa)
Corrosion Resistance	Zoo heev, tshwj xeeb tshaj yog 316 (A4) rau acid, alkali, thiab chloride kuj	Tsis zoo, nquag oxidation thiab xeb, yuav tsum tau tiv thaiv los ntawm coatings los yog plating
Siab -Tub kub Resistance	Feem ntau, austenitic stainless hlau tau txais carbide nag lossis daus saum 400 degree, ua rau rhiab heev thiab txo lub zog.	Qhov zoo tshaj plaws, chromium-molybdenum steel (B7) nthuav tawm lub zog siab tshaj plaws ntawm qhov kub siab, tsim nyog siv txog li 540 degree
Tsawg-Tsub Resistance	Zoo heev. Austenitic stainless hlau (piv txwv li, B8) yog tus qauv xaiv rau kev siv cryogenic (txog -196 degree)	Yuav tsum tau kev kho mob tshwj xeeb. Standard B7 tuaj yeem ua nkig ntawm qhov kub thiab txias; cryogenic alloy steels xws li L7 qib (A320 txuj) yuav tsum tau siv
Nqi	Kev sib piv siab (feem ntau yog vim nickel thiab molybdenum alloying ntsiab)	Tsawg heev
Magnetic Properties	Austenitic stainless hlau feem ntau tsis yog -magnetic (tej zaum yuav pom cov hlau nplaum tsis muaj zog tom qab ua tiav)	Sib nqus

Kev txiav txim siab tseem ceeb rau xaiv Flange Bolts

Load thiab kev ua haujlwm

Siab-siab/siab-kub/cyclic loads: High-lub zog flange bolts yog nyiam, nrog zoo- suab threads yog qhov kev xaiv.
Corrosive ib puag ncig: Stainless hlau flange bolts yog qhov kev xaiv.
Rau qhov tsis tshua muaj -siab, ambient- kev siv kub: Qib 8.8 hex taub hau bolts tuaj yeem raug xaiv.

Sealing Requirements

Thaum yuav tsum tau muaj kev sib khi siab siab, cov txheej txheem fastening uas muaj peev xwm xa cov khoom sib xws thiab cov khoom ua ntej yuav tsum tau ua haujlwm. Qhov kev coj ua zoo tshaj plaws rau kev ua tiav qhov no yog siv cov studs ua ke nrog hydraulic wrenches lossis torque wrenches. Hex taub hau bolts yog ib qho nyuaj rau zawm nrog kiag li niaj hnub preload.

Kev txhim kho thiab tu

Nyob rau hauv daim ntawv thov uas yuav tsum tau nquag disassembly, studs los yog tag nrho threaded studs muaj qhov zoo sib xws los ntawm kev tiv thaiv lub hauv paus threads.
Thaum qhov chaw txwv, hom bolt yuav tsum raug xaiv raws li cov qauv tshwj xeeb.

Standards thiab Specifications

Kev lag luam cuam tshuam thiab tsim cov lej yuav tsum ua raws. Cov lej no qhia meej meej txog hom ntsia liaj qhov rooj, qib khoom siv, thiab cov txheej txheem nruj kom siv rau cov kev ntsuas tshwj xeeb thiab lub ntsej muag flange.
