Spiral Wound Gasket (SWG): Product Description & Core Advantages
I. Khoom Muag Khoom
Spiral Wound Gasket (SWG) yog lub siab -kev ua tau zoo ib nrab-metallic sealing Cheebtsam, precision-tsim los ntawm alternately winding V/W-zoo li tus hlau strips thiab tsis yog-metallic muab tub lim ntaub ntawv. Cov hlau strips (ua raws li cov khoom siv ntxiv) thiab cov ntaub ntawv muab tub lim (muab kev sib khi yooj yim) yog qhov chaw -welded ntawm ob qhov kawg kom ntseeg tau cov qauv kev ncaj ncees, sib txuas cov khoom siv dag zog ntawm cov hlau nrog elastic sealing muaj peev xwm ntawm cov hlau tsis yog -.
Dav dav lees paub tias yog ntau yam gasket rau kev lag luam sealing, nws yog tsim los ua kom tau raws li qhov xav tau ntawm qhov kub thiab txias, siab siab, thiab corrosive media ib puag ncig, ua rau nws yog ib qho kev xaiv tsis tseem ceeb rau kev sib txuas flange tseem ceeb hauv ntiaj teb kev lag luam.

II. Core Advantages (Vim li cas thiaj xaiv Peb Kauv Kab Mob Gaskets)
1. Superior Sealing Performance & Kev Tiv Thaiv Kev Tiv Thaiv
Cov txheej txheem sib txuas ua ke ua rau lub gasket txhawm rau txhawm rau sib npaug hauv qab lub zog torque, nrog rau cov khoom siv muab tso rau hauv micro- qhov khoob thiab qhov tsis zoo ntawm qhov chaw flange (txog li 0.1 hli irregularities) los tsim kom nruj, impermeable foob. Txawm tias nyob rau hauv cyclic kub / siab hloov pauv, nws tuav ruaj khov sealing, zoo tiv thaiv cov nplaim taws, tshuaj lom, los yog corrosive media- tseem ceeb rau kev nyab xeeb thiab kev ua raws li ib puag ncig.
2. Exceptional Kub & Siab Resistance
Tsim los tiv thaiv kev ua haujlwm hnyav: Kub ntau ntawm -250℃rau +1000℃(nyob ntawm kev muab tub lim / hlau ua ke) thiab siab txog li 450 bar (6527 psi). Haum rau ob qho tib si cryogenic systems (piv txwv li, LNG pipelines) thiab cov khoom siv kub (xws li, boiler chav kav), outperforming tsoos ca gaskets nyob rau hauv hnyav 工况.
3. High Elasticity & Rov qab muaj peev xwm
The V/W-shaped metal strips act as "spring-like" reinforcements, providing excellent compressibility (15-30%) and recovery rate (>80%). Qhov no tso cai rau lub gasket los them nyiaj rau flange deformation tshwm sim los ntawm thermal expansion, vibration, los yog bolt so, kom ntseeg tau ntev -lub sij hawm sealing kev cia siab tsis tu ncua.
4. Kev siv tshuaj dav dav
Nrog rau customizable muab tub lim thiab hlau cov ntaub ntawv, peb gaskets tau tshaj 95% ntawm industrial media, xws li hydrocarbons, acids, alkalis, chav, hnyav, thiab corrosive tshuaj. PTFE- puv versions muaj universal tshuaj tsis kam, thaum graphite - sau cov kev xaiv excel nyob rau hauv hydrocarbon thiab chav kev pab cuam - zoo tagnrho rau ntau haiv neeg kev xav tau kev pab.
5. Durability & Nqis -Kev ua tau zoo
High- zoo hlau strips (304/316 raws li tus qauv) thiab cov khoom ua tau zoo ua kom zoo heev hnav tsis kam thiab corrosion kuj, ncua kev pab cuam lub neej los ntawm 2-3 zaug piv rau cov tsis yog xim hlau gaskets. Reusable tom qab disassembly kom zoo (nrog cov qauv tsis zoo), txo qhov hloov zaus thiab tag nrho cov tswv cuab tus nqi.
6. Yooj yim Installation & Versatility
Precision- tsim cov nplhaib sab hauv / sab nrauv (rau SO / SOI hom) kom muaj qhov chaw nruab nrab thaum lub sijhawm teeb tsa, tiv thaiv kev hloov pauv gasket lossis "tshuab- tawm" nyob rau hauv siab. Tau tshaj txhua tus qauv flange loj (GB, ASME, DIN) thiab cov khoom siv sib txawv, tshem tawm cov kev xav tau ntawm cov cuab yeej kev cai- txuag lub sijhawm thiab nqi zog.
III. Hom Kev Thov Kev Lag Luam
Roj & Gas / Petrochemical: Pipelines, reactors, siab hlab ntsha, refineries (hydrocarbons, roj crude, corrosive intermediates)
Fais fab Generation / Nuclear: Boiler chav kav, tshav kub exchangers, turbine systems (high temp / pressure steam)
