Cov yeeb nkab hlau muaj zog, yooj yim rau kev ua haujlwm nrog thiab pheej yig, tab sis txawm tias cov kua dej me me tuaj yeem noj sai sai ntawm nws, los ntawm sab hauv tawm, ua rau nws lub neej ntev.Nonmetallic piping, fiberglass thiab thermoplastics, tsis muaj lub cev lub zog ntawm cov kav dej hlau, tab sis muaj tshuaj tiv thaiv zoo heev.Yas lined piping muab qhov zoo tshaj plaws ntawm ob qho tib si cov kav dej hauv ib qho.
Yas lined piping systems muab cov tshuaj tiv thaiv ntawm cov yas thiab lub cev muaj zog ntawm cov hlau, los yog hlau alloy metallic piping systems.Qhov no yog qhov zoo tshaj plaws rau kev tuav cov kua qaub, corrosives thiab cov khoom siv phom sij.Yas lined yeeb nkab yuav fabricated nrog ib tug xoob los yog kaw nyob rau hauv liner, txawm li cas los, ib tug xauv nyob rau hauv liner txo cov nyhuv ntawm qhov sib txawv ntawm expansion coefficient ntawm cov hlau thiab cov liner.
Muaj ntau cov ntaub ntawv tsis raug hauv khw muag khoom hais txogPTFE lined yeeb nkab.Txoj kev uas qee cov neeg tsim khoom siv cov yeeb nkab yas ua rau koj tau coj los ntseeg tias nws yog qhov kev daws teeb meem rau tag nrho koj cov kab yeeb nkab uas yuav tsum tau ua thiab yuav ua txhua yam kev pabcuam los ntawm me me mus rau kev phom sij.Qhov ntawd tsuas yog tsis muaj tseeb.PTFE lined piping systems muaj kev cuam tshuam rau ntau yam teeb meem tseem ceeb:
1. PTFE lined yeeb nkab thiab PTFE lined fittings yuav tsum tau vented raws li ASTM specification rau yas lined yeeb nkab thiab yas lined fittings, F-1545.PTFE yog cov fluoropolymer permeable tshaj plaws peb kab nrog thiab vim nws yog vented, txhua yam uas permeates lub liner yog tso tawm rau hauv qhov chaw.
2. PTFE muaj cov khoom siv tsis zoo tshaj plaws ntawm cov fluoropolymer peb kab nrog.Cov pob qij txha hauv PTFE lined piping system tau raug cuam tshuam los ntawm kev sib koom ua ke thiab cov dej txias raws li tau piav qhia hauv cov xov xwm kub kub hauv qab no.Cov pob qij txha nruj yog qhov tseem ceeb rau kev ncaj ncees ntawm cov kav dej yas.Qhov tsuas yog qhov phem tshaj qhov tso koj cov khoom rau hauv qhov chaw yog muab pov tseg ntawm cov neeg ua haujlwm, hauv av, lossis cov khoom siv los ntawm kev sib koom ua ke.
3. PTFE yog qhov kim tshaj plaws fluoropolymer resin siv nyob rau hauv cov yas lined yeeb nkab thiab yas lined fittings.Nws yog 15 mus rau 20% ntawm tus nqi ntawm lwm cov fluoropolymer resins.Kev lag luam tawm yog tias koj tso cov permeation zoo heev thiab cov khoom siv kho tshuab kom txuag tau nyiaj.Cov txheej txheem ntawm cov kav dej yas feem ntau yog siv los nqa cov tshuaj uas muaj kev phom sij thiab muaj kev phom sij rau kev noj qab haus huv.
