1. Khoom Core
Lub hauv paus ntawm cov kauv-cov qauv ntawm "hlau moj khaum + kev ua haujlwm muab tub lim", qhov Flexible Spiral Wound Gasket optimizes winding density (kev lag luam nruab nrab: 8-12 tig ib centimeter) thiab interlayer adhesion los ntawm cov ntaub ntawv loj.Qhov no nyob rau hauv siab - cov ntsiab lus tsis ua hauj lwm xws li qhov kub thiab txias static sealing scenarios, ua rau nws yog ib qho ntawm 3 feem ntau adaptable gasket hom nyob rau hauv industrial sealing teb (raws li 2024 Ntiaj teb no Seals Market Report).

3. Cov yam ntxwv tseem ceeb
Dav -Range Environ mental Resistance: Raws li cov ntaub ntawv los ntawm ntau tshaj 1,200 qhov kev ua haujlwm, Lub Taub Hau Taub Hau Taub Hau Gasket siv kev sib xyaw ua ke (graphite / PTFE / asbestos- tsis pub lwm txoj hauv kev) thiab hlau strips (304/316L / Monel alloy), uas npog qhov kub ntawm -200℃txog 1,000℃filling (rau graphite filling)) thiab lub siab ntau ntawm 0 txog 40MPa, nrog rau cov tshuaj tiv thaiv corrosion txog li 98% (zoo rau cov kua qaub, alkalis, cov kuab tshuaj organic, thiab lwm yam).
Ntev -Lusing Sealing Reliability: Cov kauv- cov qauv qhov txhab tuav qhov ruaj khov compression rebound tus nqi ntawm 15%-25% (tus qauv kev lag luam Ntau dua lossis sib npaug li 12%). Cov ntaub ntawv loj qhia tau hais tias nws lub neej kev sib khi nruab nrab yog 3-5 zaug ntev dua li cov pav ca zoo tib yam, nrog tus nqi xau tsawg dua lossis sib npaug li 1 × 10⁻⁷Pa·m³ / s (ua raws li ISO 15848-1 Class BH).
High Adaptability: Tau tshaj thoob ntiaj teb cov qauv flange (ANSI, DIN, JIS) thiab sealing nto (RF - Raised Face, MFM - Txiv neej- Poj Niam ntsej muag, TG - Tus nplaig thiab Groove ntsej muag). Nws muaj qhov ua siab ntev ntawm ± 0.2mm (zoo rau siab -frequency scenarios nrog flange parallelism deviations).
Qhov sib npaug sib sib zog nqus tsim thiab muaj zog: Hlau strips (0.15-0.25mm tuab, cov ntaub ntawv loj-xav tshwj xeeb) txo qhov hnyav tag nrho los ntawm 40% piv rau cov hlau-clad gaskets. Lub nplhaib txhawb zog (carbon steel / stainless hlau) txhim khu kua muag tiv thaiv thiab tiv thaiv deformation thaum lub sij hawm installation.
Environmental Compliance: Tshaj li 95% ntawm cov khoom ua tau raws li RoHS, REACH, thiab FDA (khoom noj- qib scenarios), nrog 100% kev siv asbestos- pub dawb (ua raws li kev tswj hwm ib puag ncig thoob ntiaj teb).
4. Daim ntawv thov Scenarios
Kev lag luam Petrochemical: Flange sealing rau atmospheric thiab lub tshuab nqus tsev distillation units, catalytic cracking khoom (tsim rau cov roj crude, roj av, thiab lwm yam., nrog kub thiab siab tsis kam).
Lub Zog Zog: Kev sib khi rau cov khoom siv hluav taws xob sib txuas thiab cov kav dej hauv cov kav dej hauv thermal/nuclear fais fab (graphite-cov qauv ua kom haum rau cov cua kub siab tshaj 300℃).
Tshuaj & Pharmaceutical Industry: Flange sealing rau reactors thiab cia tso tsheb hlau luam (PTFE-cov qauv ua kom haum rau cov xov xwm corrosive heev, ua tau raws li GMP kev huv huv).
Khoom noj khoom haus & dej haus kev lag luam: Sanitary flange sealing rau brewing thiab khoom siv mis nyuj (deburred txheej txheem kom tsis txhob kis nruab nrab).
Marine Heavy Kev Lag Luam: Sealing rau marine power systems thiab ballast tank pipelines (seawater corrosion resistance, adaptable to vibration condition).
