Cov yam ntxwv thiab cov ntawv thov ntawm PTFE pob qij txha hauv kev lag luam petrochemical

I. Cov khoom siv tseem ceeb ntawm PTFE fittings

Polytetrafluoroethylene (PTFE) yog cov khoom siv hluavtaws nrog cov tshuaj fluorine atoms ntawm nws cov tub ntxhais. Nws cov qauv molecular uas cuam tshuam plaub lub pob zeb tseem ceeb:

Corrosion Kuj: PTFE yog impervious rau yuav luag txhua yam tshuaj lom neeg, nrog rau cov suliguric acid), xws li sodium hydroxide), thiab organic kuab (xws li acetone thiab toluene).

Qhov ntsuas kub hloov tau: PTFE tuaj yeem ua haujlwm stably thiab ntev {}}}}}} standing extreme້ອງ}-extreme້ອງ ntawm cov dej txias kub.

Kev sib txhuam qis qis: Nrog rau kev sib txhuam sab sib txhuam ntawm tsuas yog 0.02, nws tau nplua dua li cov dej khov, txo lub zog thaum lub sijhawm thauj tau hauv cov dej.

Sealing: Special structural designs (such as tee connectors and elastic gaskets) enable leak-free connections, with a pressure tolerance range covering low to medium- and high-pressure systems.

Cov ntawv thov raug ntawm PTFE fittings hauv kev lag luam petrochemical

1. Corrosive Thauj Systems

Hauv kev ua kom zoo thiab tshuaj chemical, cov nroj tsuag tshuaj, PTFE fittings yog siv rau:

Acid thiab Alkali Pipeline txuas: piv txwv, Luj Tshib Cov Khoom Sib Txuas Rau Hauv Hydrothines Tiv Thaiv Corrosion thiab Perforation Ntawm Cov Pob Qij Hlau.

Organic cov kuab tshuaj tiv thaiv: hauv cov pipelines nqa cov volvile cov kuab tshuaj xws li benzene thiab toluene fitts thiab deformation los tiv thaiv kev tawm tsam thiab deformation tshwm sim los ntawm cov kuab tshuaj.

Siab - kub chav dej pipelines: rau cov roj av floog hauv qab 260 degree, lawv muaj kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm kev kub siab.

2. Kev sib khi hauv qhov siab -} kev pheej hmoo thaj chaw

Reactor Inlets thiab Outlets: Hauv siab {0} PTFE Sealing, Dankai Ptfey Rittings, Dankai Ptfe Rettinging tuaj yeem tiv thaiv kev ntsuas ntawm 35 MPa, tiv thaiv cov kuab toxic.

TANKE BREYARER VALSARITS VARTIONS: Siv Hauv Kev Tso Tsheb Rau Hluav Taws Xob Los Tiv Thaiv Kev Tsim Nyog Roj Muag Los Ntawm Cov Roj Hlau Hlau Los Ntawm Cov Roj Roj Corrosive xws li Hydrogen Sulfide.

3. Kev yoog tau rau kev ua haujlwm tshwj xeeb

Cryogenic liquefied roj tshuab: thaum lub sijhawm liquefied paj (lng) cia thiab tsheb thauj mus los, ptfe} 80 degree, tiv thaiv qis qis tawg.

Siab {{0} Taug Kev Tsheb Thauj Mus Los: Pipeline Kev Sib Txuas Kev Lag Luam (}-} {1} {1}- {1} Nplooj Siab Los Ntawm Kev Ua Phem Thiab cuam tshuam cov khoom siv tsis huv.

III. Zoo ntawm PTFE fittings hauv cov ntawv thov siv

Ntev - lub neej txij nkawm: hauv kev xeb ib puag ncig muaj peev xwm kav ntev txog 3-5 zaug ntev dua li hlau fittings thiab kho zaus.

Txhim kho cov txheej txheem ruaj khov: Lub tshuab ua kom pom tseeb tias kev siv tus lej PTFE txo qis hauv nws cov kab ke piping los ntawm qhov nruab nrab ntawm 12 txi ib xyoos rau 0.5.

Zuag qhia txog kev ua kom zoo dua qub: txawm hais tias chav ntsuas tus nqi yog 30% siab dua li hlau fittings, tag nrho lub neej nyob (suav nrog kev caij tsheb thiab downtimes poob) tuaj yeem txo los ntawm 40%.

IV. Cov ntawv thov kev txwv ntawm PTFE fittings

Neeg kho tshuab muaj zog txwv: PTFE lub zog compressive (kwv yees li ntawm 13 MPa) qis dua li 500 MPA), ua rau nws tsis zoo rau cov khoom lag luam hnyav- dej piping tshuab.

Cov Khoom Siv: Hauv qab ntev - tsis muaj siab, qeeb deformation ntawm 0.1-0.5mm yuav tshwm sim, xav tau siv nrog cov hlau lub zog ib ncig.

Tus nqi -} Cov ntawv thov rhiab: Hauv cov ntawv thov corrosion xws li tsawg} Lub siab Stainless hlau tsis muaj yig ntau.

V. hom thiab specifications ntawm PTFE fittings

Hom PTFE fittings muaj xws li: flared, pagoda, xov ntawm Ferrule, thiab Flange.

PTFE phim specifications (imperial): 1/16 ", 1/1", 1/4 ", 1/4", thiab 2 "
