Dab tsi yog ptfe lined hose |BESTEFLON

Nyob rau hauv xyoo tas los no, polytetrafluoroethylene (Teflon) yog ib hom tshuaj tiv thaiv fouling thiab anti fouling khoom rau hluav taws xob thiab petrochemical kev lag luam.Txawm li cas los xij, cov teeb meem hauv qab no yuav tsum tau them nyiaj tshwj xeeb rau thaum lubPTFE kabcevkab yog welded, txwv tsis pub lub neej kev pab cuam thiab kev nyab xeeb ntawm PTFE lined pipeline yuav raug cuam tshuam.

1. Thaum ntxuav lub rooj sib dhos, nws yog nruj me ntsis txwv tsis pub ua kom puas lub hauv paus hlau.Nws yog txwv tsis pub ntaus arc ntawm lub hauv paus hlau thaum vuam.

2. Nyob rau hauv lub fillet ib feem ntawm fillet weld, qhov siab ntawm fillet weld yuav tsum ntau tshaj 5 hli, lub kaum sab xis projection yuav tsum siab tshaj los yog sib npaug rau 3 hli, thiab lub puab lub kaum sab xis yuav tsum ntau tshaj los yog sib npaug zos rau 10 hli.

3. Thaum vuam lub plhaub ntawm PTFE kab yeeb nkab, nws yog qhov zoo dua los siv txoj kev vuam ntawm ob sab pob tw vuam.Qhov no yuav tsum muaj cov txheej txheem ntawm peb cov neeg ua haujlwm, lub vuam yuav tsum tiaj tus (txoj kev hloov pauv du), tsis muaj qhov hws, vuam seam thiab slag suav nrog qhov tshwm sim, thiab qhov siab ntawm qhov vuam yuav tsum tsis txhob siab tshaj 2 hli.Tom qab welding, lub spatter tshwm sim los ntawm vuam yuav tsum raug tshem tawm tag nrho.

4. Nruam vuam yuav tsum tau saws nyob rau hauv lub vuam ntawm PTFE kab yeeb nkab, thiab lub vuam seam yuav tsum tsis txhob muaj kab nrib pleb los yog tsis tu ncua undercut.Kev Tshawb Fawb:braided PTFE hose, PTFE convoluted hose

Polytetrafluoroethylene (PTFE) yog ib qho ntawm cov npe siv feem ntau ntawm polytetrafluoroethylene.PTFE hose yog siv nyob rau hauv stainless hlau hose, yog li cov kev pab cuam lub neej ntawm hose yog ntev npaum li cas ntawm cov roj hmab hose los yog roj hmab hose qhwv nyob rau hauv stainless hlau.Nws muaj ntau yam zoo dua li cov khoom siv roj hmab.

Class I: PTFE lined ncaj yeeb nkab thiab yeeb nkab fittings

Feem ntau hu ua xoob liner yeeb nkab.Hauv cov txheej txheem no, PTFE yog siv los tig lub bar.Nws yog qhov tsim nyog rau lub cev muaj zog thiab lub siab zoo thauj mus los (xws li peb txoj kev kho cov kav dej pov tseg, thiab lwm yam), thiab yuav tsum tsis txhob siv rau lub raj xa dej nrog cov khoom thauj (xws li lub qhov nkag thiab qhov hluav taws xob ntawm lub twj tso kua mis thiab cov kav dej uas tuaj yeem tsim qhov tsis zoo. los ntawm kev poob los yog txias txias).

Txoj kab uas hla: dn25-500mm

Kev pab kub: -40-180oc

Kev pabcuam siab: 1.6 Mpa

Chav Kawm II: PTFE nruj lined ncaj yeeb nkab thiab yeeb nkab fittings

Nws yog feem ntau hu ua nruj hauv ob sab phlu yeeb nkab qhwv nrog steel hlau.

Cov txheej txheem tsim khoom: ua ntej, ob peb txheej ntawm PTFE zaj duab xis raug mob ntawm pwm, tom qab ntawd cov hlau hlau (Ø 0.5-1mm) yog spirally mob ntawm PTFE zaj duab xis, thiab tom qab ntawd ob peb txheej ntawm PTFE nyias zaj duab xis yog qhov txhab ntawm sab nraud ntawm cov hlau. hlau, thiab thaum kawg qhwv nyob rau hauv lub cub tawg rau txoj kev.Sab hauv phab ntsa ntawm PTFE lined yeeb nkab ua los ntawm cov txheej txheem no yog du, thiab sab nrauv phab ntsa yog kauv corrugated vim lub ntim thiab elastic quab yuam ntawm steel hlau.

Qhov chaw nruab nrab ntawm cov phab ntsa sab nrauv ntawm PTFE lined yeeb nkab thiab sab hauv phab ntsa ntawm cov yeeb nkab steel yog ntim nrog cov resin (tsis muaj cua seem).Lub filling resin tuaj yeem nruj nreem khi rau cov yeeb nkab steel.Nyob rau tib lub sijhawm, nws tuaj yeem raug kaw nruj nreem rau ntawm phab ntsa sab nrauv ntawm kauv PTFE liner.Tom qab kev kho ntawm cov khoom ntim puv, cov kauv ripple yog tsim uas yog occluded nrog cov phab ntsa sab nrauv ripple ntawm hauv ob sab phlu.Cov qauv no zoo ib yam li kev sib xyaw ntawm cov txiv ntoo thiab ntsia liaj qhov rooj.Ntawm qhov tod tes, nws tuaj yeem txo qis thiab them nyiaj rau thermal expansion thiab txias contraction ntawm PTFE hauv ob sab phlu;Ntawm qhov tod tes, cov hlau hlau nruj tuaj yeem txhim kho qhov tsis zoo siab ntawm PTFE hauv ob sab phlu.

Txoj kab uas hla: dn25-200mm

Ua haujlwm kub: -50-180oc

Ua haujlwm siab: 0.5-1.6mpa

Qhov thib peb hom: PTFE thawb (squeeze) yeeb nkab nruj nreem kaw nrog cov yeeb nkab ncaj

Feem ntau hu ua laub (squeeze) lined ncaj yeeb nkab, nws yog dav siv nyob rau hauv cov teb chaws tsim nyob rau hauv 1990s.

Cov txheej txheem tsim khoom: ua ntej, cov hmoov PTFE ntshuam yog siv los thawb (extrude) cov yeeb nkab, thiab tom qab ntawd nws raug yuam mus rau hauv cov yeeb nkab steel seamless (txoj kab uas hla ntawm lub liner yog me ntsis loj dua lub puab txoj kab uas hla ntawm cov yeeb nkab steel los ntawm 1.5- 2mm) los tsim ib lub seamless nruj hauv ob sab phlu.Txhawm rau tshem tawm qhov siab, nws tau muab tso rau hauv qhov cub thiab ua kom sov rau 180oC rau kev kho qhov kub thiab txias, kom nws tuaj yeem siv rau qhov kub hauv qab 180oC.Nyob rau tib lub sijhawm, thawb (squeeze) cov ncej ntawm cov yeeb nkab

Lub zog tensile yog pom tseeb zoo dua li lub qhov txhab ntawm lub qhov txhab.Lub raj xa dej muaj qhov zoo tshaj plaws tiv thaiv qhov zoo thiab qhov tsis zoo.

Qhov sib txawv ntawm PTFE hauv ob sab phlu thiab roj hmab hauv ob sab phlu

Hauv ob sab phlu tetrafluoroethylene yog siv los ntawm fluorine tus corrosion kuj, kub tsis kam, muaj zog acid thiab alkali tsis kam, zoo heev adhesion, ntev kev pab cuam lub neej thiab muaj zog nkag mus.Tag nrho cov tshuaj tsuag tetrafluoroethylene yog kev ua haujlwm siab, nws cov txheej txheem ntws li cas?1. Ua ntej txau, qhov saum npoo yuav tsum tau sandblasted thiab roughened, thiab ib txheej ntawm primer tshwj xeeb yog txau.2. Tom qab ntawd cov fluoroplastic hmoov yog them los ntawm high-voltage electrostatic khoom, thiab tusyees adsorbed nyob rau saum npoo ntawm lub workpiece nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb.3. Tom qab kub kub ci, cov clinker hais yuav yaj mus rau hauv ib tug tuab tiv thaiv txheej, uas yog nrees txuas rau saum npoo ntawm lub workpiece.Piv txwv li, 1 hli tuab txheej zaj duab xis kuj yuav tsum tau txau thiab ci ntau zaus rau 5-6 zaug.Feem ntau, qhov siab tshaj plaws thickness tuaj yeem txau rau 2 hli.PTFE hauv ob sab phlu yog cov cuab yeej siv dav siv tam sim no.Nws ua rau tag nrho cov fluorine corrosion kuj, siab purity, huv si, tsis nplaum, tsis ntub, nws tus kheej lubrication, hnav tsis kam, siab thiab kub tsis kam, rwb thaiv tsev, thiab lwm yam. Lub xeev zoo tagnrho kom ua tiav cov nyhuv txheej.Roj hmab hauv ob sab phlu kuj hu ua roj hmab hauv ob sab phlu.Nws yog los lo cov txheej txheem roj hmab ntawm cov hlau nto nrog cov nplaum kom cais cov nruab nrab corrosive los ntawm cov hlau matrix rau lub hom phiaj ntawm kev tiv thaiv.Ntuj roj hmab thiab hluavtaws roj hmab yog siv rau hauv ob sab phlu.Feem ntau ntawm cov roj hmab siv hauv cov khoom siv tshuaj lom neeg yog cov roj hmab ntuj.Lub ntsiab ntawm cov roj hmab ntuj yog cis polymer ntawm isoprene, uas yog vulcanized los ntawm kev ntxiv sulfur.Cov roj hmab vulcanized muaj qee yam kub tsis kam thiab txhua yam muaj zog.Nws tuaj yeem muab faib ua cov roj hmab muag, cov roj hmab ib nrab thiab cov roj hmab tawv peb hom.Cov roj hmab tawv muaj qhov zoo corrosion tsis kam, kev laus ua haujlwm thiab muaj zog sib txuas nrog cov hlau.Cov roj hmab muag muaj qhov ua tau zoo txias, tiv thaiv tshav kub thiab cuam tshuam, thiab muaj qee yam elasticity;semi nyuaj roj hmab yog nruab nrab ntawm ob.Ntxiv nrog rau cov oxidants muaj zog thiab qee cov kuab tshuaj, cov roj hmab tawv tuaj yeem tiv thaiv corrosion ntawm feem ntau inorganic acids, organic acids, alkalis, ntsev thiab cawv.Yog li ntawd, cov roj hmab tawv hauv ob sab phlu yog siv los ua cov khoom tseem ceeb uas tsis yog xim hlau los tiv thaiv corrosion.Vulcanized roj hmab tuaj yeem muab faib ua cov roj hmab ua ntej vulcanized, lub siab kub dej vulcanized roj hmab thiab ntuj vulcanized roj hmab.Pre vulcanized roj hmab yog siv nyob rau hauv cov khoom loj pickling.
