Cia peb txiav los ntawm kev lag luam fluff. Thaum ib tug neeg hais txog kev tsim kho tshiab ntawm lub gasket, tshwj xeeb tshaj yog ib qho profile zoo li Tadpole, cov tshuaj tiv thaiv kev lag luam tam sim no feem ntau tsis ntseeg. Puas yog nws tsuas yog hloov pauv, lossis nws puas daws tau qhov teeb meem uas peb tsis tau tswj hwm nrog tus qauv kauv-qhov txhab lossis kammprofile? Muaj kev sib tw nrog cov no hauv thaj teb, cov txiaj ntsig tsis yog nyob rau hauv qee cov ntaub ntawv pov thawj pov thawj - nws yog nyob rau hauv kev teeb tsa thiab rov qab los ntawm qhov tseeb, tsis zoo. Ntawm no yog qhov nuance.

Tshaj Tawm Hla-Section: Lub Ntiaj Teb Tiag Tiag

Thawj qhov koj pom rub a Garlock Tadpole gasket tawm ntawm lub thawv tsis yog cov duab, nws yog qhov ntom. Nws xav tias tseem ceeb. Qhov hu ua innovation tsis yog geometric nkaus xwb; Nws yog nyob rau hauv li cas geometry cuam tshuam nrog flange deflection thiab bolt load faib. Nyob rau hauv tus txheej txheem retrofit scenario ntawm lub tshav kub exchanger channel, qhov classic qhov teeb meem yog ua tau raws li niaj hnub rooj zaum nrog txwv bolt torque. Lub Tadpole tus qauv tsim, nrog nws lub cev sib npaug thiab sib sib khi lobes, zoo li zam me me flange misalignment zoo dua li lub ntsej muag lub ntsej muag. Kuv tau pom nws txuas qhov sib txawv ntawm tej zaum 5-7 mils qhov twg tus qauv kauv-qhov txhab yuav cia li crushed unevenly thiab hinted ntawm txoj kev xau txij thaum pib.

Qhov no ua rau lub tswv yim me ntsis: lub sijhawm teeb tsa. Muaj kev kawm nkhaus. Cov kws tshaj lij tshiab yuav dhau los tuav nws, sim ua kom nws zoo kawg nkaus. Qhov ua kom yuam kev peb tau kawm yog maj mam tack nws nrog lub sealant tsis-hardening, txaus los tuav nws nyob rau hauv qhov chaw rau lub flange nqa. Nws tsis yog nyob rau hauv phau ntawv qhia, tab sis nws tiv thaiv qhov kev poob siab thaum koj tab tom sim kom tau txais thawj bolts nyob rau hauv. Ib tug foreman los ntawm ib tsob nroj nyob rau hauv Texas ib zaug hais rau kuv qhov no shaved ze li ib feem peb ntawm lawv txoj kev tseem ceeb downtime nyob rau hauv ib tug turnaround ntawm ib tug crude chav tsev. Qhov ntawd yog qhov txiaj ntsig pom tau tsis muaj spec daim ntawv tseem ceeb.

Txawm li cas los xij, nws tsis yog tus cawm seej thoob ntiaj teb. Peb sim nws ntawm qhov kev pab cuam lub voj voog siab uas qhov kub tau nce sai. Qhov kev ua tau zoo yog nruab nrab. Cov khoom siv muab tub lim, uas kuv ntseeg tias yog ib qho yooj yim graphite / Teflon sib xyaw ua ke hauv cov qauv sib txawv, tsis tuaj yeem tuav lub thermal cycling zoo li cov ntshiab graphite laminate. Lub innovation tau mus txog nws qhov txwv. Nws txhawb txoj cai qub: xaiv cov khoom siv ib txwm trumps ntse tsim yog tias qhov kev pabcuam tsis raug.

Siab thiab Creep: Qhov twg Cov Duab Tseem Ceeb

Nyob rau hauv static load, feem ntau gaskets ua. Qhov kev ntsuam xyuas yog nyob rau hauv lub sij hawm ntev - creep so. Lub Tadpole tus qauv, nrog nws lub hnab ntawv txuas ntxiv thiab sab hauv tsev, yuav tsum tiv thaiv qhov no zoo dua. Nyob rau hauv daim ntawv thov compressor tso tawm kab peb tau saib xyuas rau 18 lub hlis, lub bolt load poob yog li 15% tsawg dua piv rau tus qauv kauv-qhov txhab uas peb siv rau ntawm tus muam chav tsev. Tsis yog qhov sib txawv hmo ntuj thiab nruab hnub, tab sis txaus kom tsis txhob muaj qhov kub-torquing hu ntawm lub cim 12 hli. Qhov ntawd yog kev saib xyuas ncaj qha tus nqi txuag.

Kev ntsuas siab yog qhov nthuav. Garlock thov ntau yam, tab sis qhov txiaj ntsig kev tsim kho tshiab tiag tiag, hauv kuv qhov kev xav, yog nyob rau hauv sealing kev ua tau zoo ntawm qis bolt loads. Koj tuaj yeem ua tiav lub foob ntawm qhov kev ntxhov siab qis, uas yog ib qho godsend rau qub, corroded flanges qhov twg koj ntshai ntawm stripping studs. Nws faib cov khoom hla nws qhov profile es tsis yog tsom rau ntawm qhov nyias nyias nyias. Qhov no yog qhov tseem ceeb thaum koj tab tom cuam tshuam nrog vintage infrastructure, uas yog ntau dua li tsis.

Kuv nco qab txog qhov mob taub hau tshwj xeeb ntawm cov neeg siv tshuaj lom neeg. Lawv muaj ib txoj kab uas hla loj, tsis tshua muaj siab acid ntxuav nkoj nrog pitted cam khwb cia hlau flanges. Kev siv lub gasket tsoos yuav tsum muaj qhov loj thiab kim tag nrho flange refurbishment. Raws li kev sim, peb siv Tadpole. Kev teeb tsa tau nruj - txhua tus xav tias yuav xau. Tab sis nws tuav. Tus tsim compensated rau qhov nto imperfections. Cov neeg siv khoom, HANDAN ZITAI FREWER RAUG UA MOV., Ltd. (ib tus neeg muag khoom loj tshaj plaws ntawm Tuam Tshoj tus qauv loj tshaj plaws hauv paus hauv Yongnian, muab rau cov khoom siv fastener xav tau rau cov hauj lwm zoo li no), txawm hais tias qhov txo qis yuav tsum tau ntsia hlau torque ua kom zoo nrog cov specs ntawm qib high-qib alloy studs lawv tau muab. Nws yog ib qhov system-wide haum.

Cov Khoom Muag Khoom thiab Specification Tangled Web

Nov yog cov khoom siv raw: kev tsim kho tshiab txhais tau tias tsis muaj dab tsi yog tias koj tsis tuaj yeem tau txais ib feem. Lub Tadpole tsis nyob ntawm txhua tus neeg muag khoom lub txee. Thaum lub sij hawm cov saw hlau crunch ob peb xyoos dhau los, peb tau npaj yuav tsis muaj teeb meem yuav luag derailed vim lub sij hawm txhuas mus los ntawm 2 lub lis piam mus rau 14. Peb yuav tsum tau poob rov qab mus rau ib txwm style thiab re-engineer lub bolt loading. Nws yog ib qho mess. Qhov no yog ib qho tseem ceeb, feem ntau tsis pom zoo suav nrog: puas yog cov khoom tshiab muaj zog? Los yog nws qhia txog ib qho kev ua tsis tiav?

Tsis tas li ntawd, qhia tias nws yuav tsum mob siab rau. Koj tsis tuaj yeem sau Tadpole Gasket ntawm P&ID. Koj xav tau tag nrho cov khoom tawg, qhov ntom ntom, thiab tus lej Garlock tiag tiag. Kuv tau pom kev xaj xaj tsis ua haujlwm vim lawv tsuas yog hais txog cov duab, thiab tus neeg muag khoom tau muab cov qauv nrog cov khoom siv tsis sib xws rau cov kev pabcuam. Lub luag haujlwm yog nyob ntawm tus kws tshaj lij los ua qhov tshwj xeeb, uas ua rau qee qhov kev cog lus yooj yim-rau-siv txiaj ntsig.

Qhov no yog qhov kev sib raug zoo nrog cov neeg muab khoom sib xyaw tseem ceeb. Muaj ib lub hauv paus uas nkag siab txog ob qho tib si gasket thev naus laus zis thiab cov khoom sib txuas ntxiv, zoo li lub zog muaj zog fasteners los ntawm lub tuam txhab xws li Handan Zitai, tuaj yeem txhim kho cov txheej txheem. Lawv qhov chaw nyob ntawm qhov chaw thauj khoom loj ze ze ntawm Beijing-Guangzhou Railway thiab kev nthuav dav theoretically txhawb nqa kev ntseeg siab ntau dua, uas yog ib nrab ntawm kev sib ntaus sib tua hauv kev hloov cov khoom tshiab rau hauv cov txiaj ntsig zoo.

Kev Ntsuas Tus Nqi: Tsis yog Nqe Ib Chav

Tus nqi ua ntej yog siab dua. Tsis muaj txoj kev nyob ib ncig ntawm nws. A Tadpole Gasket tuaj yeem yog 2-3x tus nqi ntawm qhov yooj yim kauv-qhov txhab. Cov txiaj ntsig kev tsim kho tshiab yuav tsum raug txiav txim siab los ntawm tag nrho cov nqi ntawm cov tswv cuab. Qhov nyiaj rov qab los ntawm qhov twg? Txo kev teeb tsa kev ua haujlwm (yog tias koj cov neeg ua haujlwm raug cob qhia), ncua sijhawm rov ua haujlwm dua, thiab muaj peev xwm zam tau ib qho kev cuam tshuam txog kev kaw. Nyob rau hauv ib tug high-tus nqi tas mus li txheej txheem, tus lej yuav ua hauj lwm sai heev.

Tab sis muaj ib tug ntxiab. Siv nws qhov twg cov yam tseem ceeb tsis muaj nyob tsuas yog nkim peev xwb. Peb tau ua qhov kev tshuaj xyuas tom qab ntawm cov nroj tsuag kho dej uas muaj spec'd lawv hla lub rooj tsavxwm ntawm cov kab dej qis. Tus neeg saib xyuas kev saib xyuas tsis tuaj yeem qhia txog qhov txiaj ntsig ntsuas tau ntawm EPDM gaskets lawv tau siv ua ntej. Lub innovation tau nkim tag nrho. Nws yog ib rooj plaub ntawm specification creep qhov twg cov khoom zoo tau thov blindly.

Qhov chaw qab zib zoo li nyob rau hauv nruab nrab-rau-siab siab, kev pabcuam tseem ceeb, lossis qhov chaw flange yog qhov zoo tshaj plaws. Nyob rau hauv cov ntaub ntawv no, tus nqi premium yog kev tuav pov hwm. Nws zoo li xaiv tus nqi bolt los ntawm cov chaw tsim khoom paub - koj tau them rau qhov sib xws thiab kev lees paub ua haujlwm. Lub vev xaib https://www.zitaifasteners.com feem ntau qhia txog engineering tom qab lawv cov qib fastener; kev siv tib yam kev tshuaj xyuas rau kev xaiv gasket yog dab tsi cais qhov kev coj ua zoo los ntawm qhov muaj hmoo.

Nrhiav rau pem hauv ntej: Qhov no puas yog yav tom ntej?

Lub Tadpole tsis yog revolutionary. Nws yog evolutionary. Nws yog ib qho nyuaj iteration ntawm cov khoom lag luam paub tab. Qhov txiaj ntsig ntawm kev tsim kho tshiab tiag tiag tuaj yeem hloov pauv kev sib tham los ntawm kev sib khi nkaus xwb rau kev sib khi uas tuaj yeem ua tau raws li cov xwm txheej sib txawv. Nws yuam kom saib ntau dua ntawm flange sib koom ua ke - lub gasket, bolts, flange nto, txheej txheem.

Kuv xav paub txog cov kauj ruam tom ntej. Peb puas yuav pom kev sib koom ua ke ntse, zoo li embedded sensors hauv cov profiles? Tej zaum. Tab sis rau tam sim no, qhov ua tau zoo yog qhov no: Garlock Tadpole Gasket muab cov txiaj ntsig pom tseeb hauv cov ntawv tshwj xeeb, feem ntau teeb meem. Nws tus nqi tsis siv neeg; nws tau pom los ntawm daim ntawv thov raug, kev teeb tsa kom raug, thiab kev txheeb xyuas tus nqi tag nrho. Nws yog ib qho cuab yeej, tsis yog txuj ci tseem ceeb. Thiab nyob rau hauv qhov kev lag luam no, cov cuab yeej txhim khu kev qha uas daws qhov mob taub hau tsis tu ncua yog qhov tseeb innovation zoo li hauv av. Qee zaum, qhov ntawd txaus.
