Twin Ferrule Fittings (ob chav ferrule fittings) Xaiv Qhia rau Gas & Liquid Media

Gases thiab kua muaj ntau yam sib txawv ntawm lub cev, uas ncaj qha ua rau sib txawv logics rau ferrule haum xaiv. Phau ntawv qhia no khaws tag nrho cov ntaub ntawv tseem ceeb tshaj lij tshaj lij thiab rhuav tshem cov ntsiab lus nyuaj hauv cov laj thawj yooj yim, ua kom nkag siab rau cov tsis yog - cov kws tshaj lij thiab siv ncaj qha rau cov neeg ua haujlwm engineering.

1. Qhov Tseem Ceeb Ntawm Cov Khoom Sib Txawv Ntawm Cov Roj & Cov Kua Dej: Lub hauv paus tseem ceeb rau kev xaiv

Gases thiab kua yog qhov tseem ceeb sib txawv ntawm qhov ntom, molecular loj thiab compressibility, uas tsim lub hauv paus ntawm kev xaiv haum rau sealing, siab tsis kam thiab cov khoom sib txuam. Tsis muaj universal ferrule haum tuaj yeem hloov kho rau ob hom xov xwm tib lub sijhawm.

Gas Media: Tsis tshua muaj siab compressibility, me me molecular txoj kab uas hla, yooj yim rau xau los ntawm micro gaps, thiab nws muaj kev kub siab hloov pauv thaum lub sij hawm ntws. Cov ntsiab lus tseem ceeb:Tsis muaj kev sib khi, kev kub siab ua haujlwm, tiv thaiv tawg, xoom xau

Kua Media: Incompressible, dav viscosity ntau, feem ntau muaj cov khoom siv los yog nrog kev co thiab kub hloov. Cov ntsiab lus tseem ceeb:hnav tsis kam, tiv thaiv -loosing, kub sib txawv kam rau ua

2. Ferrule Fitting xaiv rau Gas Media: nruj sealing & kev nyab xeeb hauv qab kab (Cov ntaub ntawv tseem ceeb)

Cov roj molecules khiav tau yooj yim, thiab txawm tias micro- nplai qhov khoob tuaj yeem ua rau cov pa tawm. Cov pa phem kuj tseem cuam tshuam txog kev tiv thaiv tawg, yog li txhua qhov kev ntsuas yuav tsum ua raws li cov qauv meej.

2.1 Siab -Purity Gas Scenarios (Semiconductor Special Gas Delivery)

Cov dej me me los yog cov kab mob sib kis yuav ncaj qha ua rau cov khoom seem.316L stainless hlau ferrule fittingsnrog nto roughnessRa Tsawg dua lossis sib npaug li 0.8μmthiab kev kho electropolishing yuav tsum tau siv los tshem tawm cov qhov khoob me me thiab ua tiav ze rau -zero to.

2.2 Siab-Cov Cuab Yeej Siv Hluav Taws Xob (Hydraulic Siab-Pressure Gas Circuits)

Gas compressibility tuaj yeem ua rau muaj kev kub ntxhov siab.63MPa ob chav ferrule fittingsyuav tsum tau, nrog rau kev txiav qhov tob ntawm ferrule npoo nruj me ntsis tswj ntawm0.25mm-0.5 hlilos xyuas kom meej sealing kev ncaj ncees nyob rau hauv siab siab.

2.3 Flammable & Explosive Gas Scenarios (Hydrogen, Methane)

Rau thaj tsam 1 tawg - thaj chaw pov thawj,tawg- pov thawj fittings nrog Ex d IIC T6 ntawv pov thawjyuav tsum tau txais kev pom zoo, thiab qhov sib txawv ntawm cov txiv ntseej thiab lub cev haum yog txwv kom tsawg dua lossis sib npaug li 0.1 hli txhawm rau tshem tawm cov phom sij txaus ntshai ntawm qhov chaw thiab tuav cov kab hauv qab rau kev tawg- pov thawj kev nyab xeeb.

3. Ferrule Fitting xaiv rau cov kua Media: Resisting Wear & Vibration (Core Data)

Cov kua dej tsis sib haum, thiab lawv cov dej ntws feem ntau yog nrog los ntawm kev yaig thiab cov raj xa dej vibration. Qhov tseem ceeb yog daws qhov hnav, xoob thiab qis -kub embrittlement lossis siab -kub deformation teeb meem.

3.1 Khoom-Khoom ua kua (Slurry, Coal-Dej Mixture)

Sab hauv phab ntsa ntawm fittings raug kev puas tsuaj tas mus li thiab hnav.stellite alloy hardfaced ob ferrule fittingsyuav tsum tau, nrog hardfacing thickness Ntau dua los yog sib npaug rau 3 hli thiab hardness Ntau dua los yog sib npaug rau HRC45, muab ultra-siab hnav tsis kam thiab ntev kev pab cuam lub neej.

3.2 Vibration Ua Haujlwm Liquids (Marine Diesel Cav Roj Pipelines)

Kua pulsation ua rau siab - zaus vibration, ua rau yooj yim loosening ntawm cov khoom siv zoo tib yam.Ferrule fittings nrog xauv ringsyog cov qauv kev teeb tsa, uas tuav lub raj xa dej kom nruj ntawm lub phaj caij nplooj ntoos hlav ua ntej-tightening quab yuam kom tiv thaiv cov txiv ntoo loosening thiab to hauv qab vibration.

3.3 Cov kua dej kub heev

Rau cryogenic kua nitrogen (-196 degree),304L cryogenic stainless hlaunrog qis- qhov kub thiab txias cuam tshuam lub zog Ntau dua lossis sib npaug ntawm 34J yog xaiv kom tsis txhob txias embrittlement thiab tawg; rau siab -kub kub hloov roj, tshwj xeeb tshav kub- resistant steel fittings yog siv los tiv taus kub tsis deformation.

4. Kev Ua Haujlwm Kev Ua Haujlwm Kev Kho Kom Zoo: Kev Ua Haujlwm Siab, Kub & Kev Xaiv Cov Qauv

4.1 Cov Cai Tseem Ceeb rau Kev Ruaj Ntseg & Kub

Siab redundancy: Haum nominal siab Ntau dua los yog sib npaug rau1.5 npaug ntawm kev ua haujlwm siab tshaj plaws for sufficient safety margin. For pressure difference >1.0MPa (siab-dej dav hlau txiav), ob -theem ferrule fittings yog siv los tso siab maj mam.

High - qhov kub thiab txias (siab dua 300 degree, nuclear fais fab nroj tsuag, thermal fais fab nroj tsuag): 6Mo super stainless hlau yog xaiv rau corrosion kuj, ua ke nrog bellows compensators thiab ferrule fittings nqus thermal expansion stress.

4.2 Kev xaiv cov qauv sib txuam

High-siab gas: Ua ntejob chav ferrule fittings thiab VCR hlau- kaw fittings; VCR fittings muaj tus nqi xau tsawg li 1 × 10⁻⁹ Pa·m³ / s, ua tau raws li ultra- kev sib khi nruj heev.

Cov pa qis- cov kua dej siab (dej siv dej): Ib qho ferrule fittings txaus; hydraulic systems ntawm mobile heavy khoom: serrated anti-loosing ferrule fittings, nrog kev co qaug zog lub neej Ntau tshaj los yog sib npaug rau 20,000 cycles.

5. Kev Xaiv Matrix: Kev sib tw nrawm rau kev ua haujlwm (Rau cov pib tshiab)

Foob Cov Lus Qhia: Cov ntsaws ruaj ruaj (PTFE / Fluororubber) muaj kev sib khi zoo heev tab sis qhov kub tsis kam (tsawg dua lossis sib npaug li 250 degree); hard seals (hlau / ceramic) tiv taus siab thiab kub nrog zoo hnav tsis kam, tab sis yog siv ceev faj nyob rau hauv ultra-siab purity to{2}} pov thawj scenarios; Composite seals (hlau pob txha pob txha + mos txheej) sib npaug ntawm ob lub zog thiab yog qhov kev xaiv thoob ntiaj teb.

6. Txoj Cai Txhim Kho: Tiv Thaiv Sab saum toj- Qib Fittings Los Ntawm Kev Ua Tsis Zoo Vim Kev Txhim Kho Tsis Zoo (Cov Ntaub Ntawv Tseem Ceeb)

Kev txhim kho tsis raug yog qhov tseem ceeb ntawm kev sib tsoo thiab tawg. Nco ntsoov peb qhov txwv tsis pub thiab cov kev teeb tsa tsis raug hauv qab no:

6.1 Peb Qhov Kev Txwv rau Ntawm -Qhov Chaw Nruab

Tsis txhob tsim txom sealant: Nws yooj yim thaiv cov raj xa dej kom yooj yim thiab ua rau muaj kab mob sib kis. Muaj ib rooj plaub uas hydraulic system tuag tes tuag taw los ntawm sealant misuse coj mus rau ib tug txij nkawm nqi txog li 500,000 RMB.

Tsis txhob quab yuam rub lossis khoov cov kav dej: Lub zog sab nraud ua rau qaug zog ntawm cov fittings, uas yog lub hauv paus ua rau kev puas tsuaj.

Tsis txhob rov disassembly thiab sib dhos blindly: Txhua disassembly thiab sib dhos khawb lub sealing nto irreversibly, ua rau maj mam to.

6.2 Precise Installation Parameters

Ua ntej- sib dhos torque rau stainless hlau fittings: 15N·m-20N·m

Ua ntej- sib dhos torque rau tooj liab alloy fittings: 8N·m-12N·m

Txiav qhov tob ntawm ferrule puab ntug: 0.1mm-0.2mm; Tshaj li 0.5 hli yuav txo qhov kev pab cuam lub neej ntawm 60% sharply.

7. Cov ntaub ntawv siv tau: Siv ceev ceev

Case 1: Ntev-Nyob deb ntawm Natural Gas Pipeline (4.0MPa, Trace Hydrogen Sulfide-muaj Gas)

Cov kav dej loj: ASTM A105N forged steel + npib tsib xee-plated ob chav ferrule fittings, ntsuas kub siab ua haujlwm thiab tiv thaiv corrosion; ntsuas kev sib txuas kawg: Hloov kho mus rau 316L VCR hlau- kaw fittings kom tshem tawm cov pa paug tawm.

Case 2: Polyethylene Polymerization Unit (220℃, Siab -Viscosity Solid- Muaj Kua)

Pub pipeline: Stellite alloy hardfaced fittings rau yaig kuj; Cov raj xa dej: Duplex steel 2205 V- hom ferrule fittings kom ruaj khov thiab tsis muaj zog; Tshem tawm kawg: Nruab nrog scraper- hom ferrule gate li qub kom tshem tawm cov ntaub nplaum.

Peb lub tuam txhab Depo valve thiab haum yog kua thiab roj kev lag luam kws tshaj lij, peb yuav pab koj xaiv thiab tsim txoj cai stainless hlau compression fittings, los yog tooj dag compression haum connector .Ntau cov ntaub ntawv, koj tuaj yeem tiv tauj peb .Peb ib txwm nyob ntawm no
