Stainless Hlau Phaj Washers

Kev tsim cov txheej txheem ntawm Stainless Hlau Phaj Washers muaj qhov cuam tshuam tseem ceeb rau kev faib tawm hauv kev ntxhov siab. Loj-size washers feem ntau yog tsim los ntawm stamping thiab blanking ua raws li kev ua tiav. Lawv flatness yog ze ze rau qhov pib lub xeev ntawm lub phaj thiab pwm qhov sib txawv. Raws li ASTM E18 Rockwell hardness test, lub hardness ntawm ntug ntawm lub stamped phaj gasket tuaj yeem nce li ntawm 12% piv rau thaj tsam hauv nruab nrab vim kev ua haujlwm txias. Noj 304 stainless hlau ua piv txwv, lub hardness ntawm lub hauv paus cheeb tsam yog hais txog HRB 85, ​​thiab ntug yuav nce mus rau HRB 95. Txawm hais tias qhov hardness gradient no txhim khu lub ntug compressive kuj, nws kuj yuav ua rau lub zos kev nyuaj siab concentration nyob rau hauv lub tom ntej siv. Yog li ntawd, cov txheej txheem kev ntxhov siab feem ntau yog ntxiv tom qab stamping kom homogenize tag nrho hardness rau HRB. 80 rau 88 ntau yam. Nyob rau tib lub sijhawm, raws li ASTM E8 tensile xeem, qhov elongation ntawm lub gasket tom qab annealing yog nce los ntawm 20% mus rau 45%, uas ua kom muaj kev tiv thaiv rau nkig tawg, ua rau nws haum rau flange kev sib txuas ntawm cov khoom siv mining uas cuam tshuam cov loads.

Nyob rau hauv ib puag ncig rhiab rau electrochemical corrosion, tshwj xeeb yuav tsum tau them rau cov khoom ua ke thiab installation torque ntawm stainless hlau phaj washers. Thaum siv nrog carbon steel bolts, muaj peev xwm sib txawv ntawm cov ntxhua khaub ncaws thiab bolts. Raws li ASTM G71 galvanic corrosion test method, tom qab 316L stainless steel washers thiab carbon steel bolts yog ua ke nyob rau hauv simulated seawater, tus nqi corrosion ntawm carbon steel bolts accelerates ntawm 0.1 hli ib xyoos twg thaum raug ib leeg mus rau 0.5 hli ib xyoo. Qhov no txhais tau hais tias cov txheej txheej insulating yuav tsum tau ntxiv ntawm cov ntxhua khaub ncaws thiab cov bolts lossis bolts ntawm tib cov khoom yuav tsum tau xaiv. Nyob rau tib lub sijhawm, raws li kev ntsuas kev sib txhuam coefficient ntawm VDI 2230, kev sib txhuam coefficient ntawm kev txhawb nqa nto ntawm lub tshuab ntxhua khaub ncaws thiab passivated stainless hlau ntxhua khaub ncaws thiab stainless hlau txiv ntoo yog li 0.15 txog 0.22, uas yog qhov siab dua li ntawm galvanized washer thiab carbon steel txiv ntoo, uas yog 0.018. Thaum lub hom phiaj preload quab yuam yog 100 kN, qhov yuav tsum tau nruj torque nce los ntawm 300 Nm rau galvanized ua ke mus rau 420 Nm, nce li ntawm 40%. Yog li ntawd, ntawm-qhov chaw teeb tsa yuav tsum rov ntsuas tus nqi torque raws li qhov ntsuas kev sib txhuam coefficient kom tsis txhob flange to lossis ntsia liaj qhov rooj loosening tshwm sim los ntawm tsis txaus ua ntej-tightening force. Qhov kev txiav txim siab no yog qhov tseem ceeb heev hauv kev ceev cov roj platform piping systems thiab tshuaj reactor taub hau.

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

Cov duab kos, cov khoom siv raw, kev kho saum npoo, thiab lwm cov 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 them nqi, cov nqe lus ntawm kev lag luam, hom ntim khoom, 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.
