Stainless Steel Structural Bolts

Stainless steel structural bolts plays lub luag hauj lwm irreplaceable nyob rau hauv txuas hniav, yees thiab hnyav machinery sib txuas. Lawv cov ntaub ntawv feem ntau yog ua los ntawm austenitic stainless hlau xws li A4 lossis A2 qib. Raws li ISO 3506-1 tus qauv, qhov tsawg kawg nkaus tensile lub zog ntawm A4- 80 qib bolts ncav cuag 800 MPa, thiab qhov tsis yog - lub zog txuas ntxiv tsis pub tsawg dua 600 MPa. Qhov kev ntsuas lub zog no ua kom ntseeg tau tias cov bolts tuaj yeem tswj tau qhov elastic deformation ntau yam thaum raug hloov pauv thiab tsis txhob hnav cov hnab yas. Nyob rau tib lub sijhawm, nws zoo heev corrosion kuj yog vim chromium{15}}nickel{19}} molybdenum alloy muaj pes tsawg leeg. Nyob rau hauv lub sij hawm siv ntsev tsuag simulating ib puag ncig marine, raws li ASTM B117 specification, hom ntsia liaj qhov rooj no tuaj yeem nyob tsis muaj xeb liab ntawm qhov chaw tom qab tsib puas teev raug, yog li ua kom muaj kev ntseeg siab ntawm kev pabcuam sab nraum zoov mus ntev. Hauv cov haujlwm tiag tiag, txoj kab uas hla ntawm cov bolts ntau ntawm M12 txog M36. Thaum sib txuam nrog cov txiv ntseej thiab cov ntxhua khaub ncaws, lawv cov kev sib txhuam-hom kev sib txuas tuaj yeem xa cov quab yuam shear thiab txo qhov kev pheej hmoo ntawm kev xoob.

Txawm li cas los xij, kev txhim kho torque thiab pretightening quab yuam ntawm stainless hlau structural bolts yuav tsum tau tswj nrog ceev faj heev vim hais tias cov xov txhuam coefficient feem ntau yog siab dua li cov carbon steel bolts. Raws li VDI 2230 cov txheej txheem kev suav cov txheej txheem, thaum kev sib txhuam coefficient hloov pauv hauv thaj tsam ntawm 0.15 txog 0.30, lub zog sib txawv ntawm pretightening tsim los ntawm tib lub zog nruj tuaj yeem ncav cuag 40%. Yog li ntawd, txoj kev torque ntxiv rau lub kaum ntse ntse feem ntau yog siv rau ntawm qhov chaw kom nruj nruj. Piv txwv li, rau A4-80 bolts nrog M20 specifications, qhov pom zoo torque tus nqi yog hais txog 450 Nm, thiab pretightening quab yuam tuaj yeem ncav cuag 125,000 N. Tus nqi no yog raws li tus qauv kev ua haujlwm uas cov xov paj txoj kab uas hla thiab kev sib txhuam coefficient ntawm cov kabmob nto yog xoom.2. Yog hais tias lub lubrication tej yam kev mob hloov, lub torque yuav tsum tau recalibrated, txwv tsis pub dhau pretightening quab yuam yuav ua rau lub stainless hlau xov mus txeeb, thaum tsis txaus pretightening quab yuam yuav ua rau qaug zog puas. Yog li ntawd, torque wrenches thiab ultrasonic axial quab yuam saib feem ntau yog siv thaum lub sij hawm tsim kho los xyuas kom meej tias kev ruaj ntseg redundancy ntawm cov kev twb kev txuas khub ua tau raws li qhov yuav tsum tau tsim.

Tau txais cov duab kos los ntawm cov neeg siv khoom lossis tsim cov duab kos raws li lawv cov kev qhia tshwj xeeb lossis cov qauv.

Cov duab kos, cov khoom siv raw, kev kho deg, thiab lwm yam ntsiab lus tau lees paub los ntawm ob tog.

Muab cov lus tsocai, xyuas kom meej tias qhov kev txiav txim kom muaj nuj nqis yog qhov tseeb, thiab suav nrog tag nrho cov ntsiab lus tseem ceeb,

xws li cov nqe lus ntawm kev them nyiaj, cov nqe lus ntawm kev lag luam, hom ntim, thiab lwm yam.

Ua raws li cov duab kos thiab cov qauv raws nraim thaum tsim cov khoom.

Nws tau ua tib zoo ntim thiab xa mus rau cov neeg siv khoom tom qab kev tshuaj xyuas zaum kawg.
