Xaiv qhov tawg-Cov pov thawj Hoses rau Metering Skids

Xaiv qhov tawg-Cov pov thawj Hoses rau Metering Skids
Kev xaiv ntawm tawg-cov pov thawj hoses (explosion-cov ntaub ntawv pov thawj saj zawg zog conduits) rau metering skids tsom rau kev ua raws li kev tawg- cov ntaub ntawv pov thawj, cov khoom siv sib xws, siab / kub sib txuam, qhov ntev thiab kev teeb tsa, nrog rau kev tiv thaiv tsim nyog thiab kev tiv thaiv corrosion, uas yuav tsum ua raws li cov qauv GB5 30 8.
I. Cov Txheej Txheem Xaiv Qhov Tseem Ceeb (Ua Raws Li Ua Ntej)
1. Kev tawg -Qhov pov thawj thiab ntawv pov thawj (tseem ceeb)
Explosion-pov thawj cim: Yuav tsum phim qhov chaw muaj kev puas tsuaj (Zone 0/1/2, gas/plua plav) qhov twg lub metering skid raug ntsia.
Gas cua: Ex d IIB T4 Gb, Ex d IIC T6 Gb (common)
Plua plav huab cua: Ex tD A21 IP65 T125℃Db
Daim ntawv pov thawj yuav tsum tau: Lub hose thiab fittings los ua ke yuav tsum tau ntawv pov thawj los ntawm lub teb chaws tawg - pov thawj txoj cai nrog ib tug siv tau explosion - ntawv pov thawj.
Qauv: GB 3836.1/2, GB 50058-2014, AQ 3009.
2. Kev xaiv cov khoom siv (raws li qhov nruab nrab thiab ib puag ncig)
Cov khoom siv lub cev tseem ceeb
304/316 stainless hlau: corrosion{2}}resistant, kub ntau yam -40℃~ 300 degree, haum rau natural gas, roj thiab roj, tshuaj media.
Cov pa roj carbon steel nrog galvanizing / chrome plating: tus nqi qis, rau qhuav, tsis yog - corrosive ib puag ncig.
Inner sealing: NBR, FKM (Viton), PTFE, tau tshaj tawm (roj, roj, dej, corrosive kua).
Kev tiv thaiv sab nraud: Stainless hlau braided mesh (siab thiab tensile kuj, nas{0}} pov thawj), PVC / roj hmab sheath (waterproof, hnav-resistant).
3. Kev sib txuam ntawm qhov kub thiab txias
Rated ua hauj lwm siab: Ntau tshaj los yog sib npaug rau siab tshaj plaws ua hauj lwm siab ntawm lub metering skid system (feem ntau 1.6/2.5/4.0/6.4 MPa).
Lub siab tawg: Ntau dua lossis sib npaug li 3 npaug ntawm qhov ntsuas kev ua haujlwm siab.
Qhov kub thiab txias: Npog rau ntawm - qhov chaw yam tsawg kawg nkaus thiab siab tshaj plaws (piv txwv li, -40℃~+150℃).
4. Dimensions thiab Installation Parameters
Nominal txoj kab uas hla (DN): Match khoom sib txuas (DN15/20/25/32/40/50).
Ntev: Raws li qhov tseeb ntawm - qhov chaw nyob deb, nrog kev tso cai txaus kom tsis txhob ncab.
Khoov vojvoog: Ntau dua lossis sib npaug li 5 npaug ntawm txoj kab uas hla sab nraud (yuav tsum tau los ntawm GB 50257, AQ 3009).
Kev sib txuas hom: Txiv neej / poj niam threads (G, NPT, M), flanges, ceev couplings, raws li cov khoom siv ports.
5. Qib Kev Tiv Thaiv thiab Corrosion Resistance
Ingress tiv thaiv (IP ntsuam xyuas): Ntau dua lossis sib npaug ntawm IP65 (plua plav- nruj, txaws- pov thawj).
Corrosion resistance qib: WF1 rau thaj chaw dav dav, WF2 rau cov ntug dej hiav txwv / tshuaj lom neeg.
Anti- zoo li qub: Rau cov khoom siv hluav taws xob thiab cov khoom tawg, lub hose yuav tsum ua kom muaj kev ua haujlwm siab nrog qhov chaw tiv thaiv tsawg dua lossis sib npaug li 10⁶ Ω.
II. Cov txheej txheem xaiv (tseem siv tau ncaj qha)
Txiav txim siab thaj chaw muaj kev phom sij: roj / plua plav, kev faib tawm tsam (Zone 1/2), pab pawg nruab nrab (IIA / IIB / IIC), chav kawm kub (T4 / T5 / T6).
Qhia meej qhov nruab nrab: hom nruab nrab, siab, kub, corrosiveness.
Kev sib tsoo tawg- pov thawj cim: xaiv cov hoses nrog cov cim Ex cim thiab ntawv pov thawj.
Paub meej cov qauv thiab cov khoom siv: stainless hlau nrog kev sib khi thiab kev tiv thaiv braided.
Txiav qhov ntev: DN, ntev, sib txuas, khoov vojvoog.
Tshawb xyuas kev tiv thaiv / corrosion kuj / anti- kev ua haujlwm zoo li qub: IP ntsuas, WF qib, conductivity.
Tshawb xyuas cov qauv thiab daim ntawv pov thawj: GB 3836, GB 50058, siv tau tawg- daim ntawv pov thawj.
III. Hom Kev Xaiv Piv Txwv (Natural Gas Metering Skid)
Explosion-proof marking: Ex d IIB T4 Gb
Khoom siv: 304 stainless hlau bellows + 304 braided mesh + FKM foob
Siab: Rated 2.5 MPa, tawg 7.5 MPa
Kub: -20℃~ +80 degree
Nominal txoj kab uas hla: DN20
Ntev: 500 mm
Kev sib txuas: G3/4" poj niam xov ntawm ob qho kawg
Kev tiv thaiv: IP65, WF2
IV. Xaiv Taboos
Tsuas yog siv lub hose yam tsis muaj ntawv pov thawj tag nrho (lub hose thiab fittings yuav tsum tawg- pov thawj tag nrho).
Khoov vojvoog tsawg dua 5 npaug ntawm txoj kab uas hla sab nraud (kev puas tsuaj tawg-cov qauv pov thawj).
Cov khoom tsis sib haum nrog qhov nruab nrab (corrosion, o, to).
Kev ntsuas siab / ntsuas kub qis dua qhov kev ua haujlwm ntawm lub cev.
Tsis muaj tawg- ntawv pov thawj los yog daim ntawv pov thawj tas sij hawm.
