Hom

Nws muaj ob qho kev cai lij choj ntawm Tebchaws Meskas los txiav txim siab txog qhov zoo ntawm cov kab ntawv PTFE. MIL-T-27730A (ib qho kev ua tub rog tsis tseem ceeb hauv feem ntau siv hauv kev lag luam hauv Teb Chaws Asmeskas) yuav tsum muaj qhov tsawg tuab ntawm 3.5 mils thiab purity PTFE yam tsawg kawg nkaus 99%. Qhov thib ob txuj ci, AA-58092, yog ib qib kev lag luam uas tswj cov thickness ntawm MIL-T-27730A thiab ntxiv qhov tsawg kawg ntawm qhov sib npaug ntawm 1.2 g / cm3.Relevant qauv yuav txawv ntawm cov lag luam; ntaub nplaum rau cov roj fittings (rau UK cov cai tswj roj) yuav tsum tau cia kom zoo dua li cov dej. Txawm hais tias PTFE nws tus kheej yog tsim rau siv cov tshuab muaj roj, cov qhab nia tseem yuav tsum paub tias tsis pub dawb los ntawm roj.

  Cov ntaub ntawv kaw lus siv rau hauv cov kav dej siv yog feem ntau yog xim dawb, tab sis nws kuj muaj nyob hauv ntau xim.

Dawb - siv rau NPT threads txog li 3/8 nti

Daj - siv rau NPT threads 1/2 nti rau 2 nti, feem ntau sau hais tias "roj tuav"

Paj yeeb - siv rau NPT threads 1/2 nti rau 2 nti, zoo rau propane thiab lwm yam roj av hlab ntses

Ntsuab - roj dawb PTFE siv rau cov pa kab thiab qee cov kev kho mob gasses

Grey - muaj xim nickel, anti-seizing, anti-galling thiab anti-corrosion, siv rau cov kav hlau tsis txhuam
