Raws li ib tug neeg siv, yuav ua li cas thiaj li tau txais kev soj ntsuam ntawm PE yeeb nkab thiab cov yeeb nkab fittings

Polyethylene (PE) cov kav dej muaj cov khoom zoo xws li qis- qhov kub thiab txias tsis kam tiv thaiv, yoog raws, thiab corrosion kuj, thiab tau dav siv hauv cov dej, cov chaw hauv nroog, cov chaw tsim khoom, thiab kev ua liaj ua teb. Txhawm rau kom ua tiav kev tsim kho kom zoo thiab siv sijhawm ntev -kev nyab xeeb siv cov kav dej polyethylene (PE) cov kav dej, kev lees txais cov khoom siv yeeb nkab los ntawm cov neeg siv yog qhov tseem ceeb tshwj xeeb. Cov khoom soj ntsuam tseem ceeb thaum txais cov ntaub ntawv tau sau tseg raws li hauv qab no, thov xa mus rau lawv:
1. Lub Hoobkas daim ntawv pov thawj ntawm kev ua raws / kev xeem daim ntawv qhia: Nws yuav tsum muaj cov ncauj lus kom ntxaws xws li cov chaw tsim khoom lub npe, cov qauv siv tau, thiab cov ntsuas ntsuas cuam tshuam.
2. Qib thiab hom khoom ntawm polyethylene raw khoom (PE80 los yog PE100): Cov ntaub ntawv cov ntaub ntawv thiab npe yuav tsum tau qhia nyob rau hauv cov yeeb nkab cim cov ntaub ntawv.
3. Cov tsos mob: Kev kuaj pom pom. Sab hauv thiab sab nrauv ntawm cov yeeb nkab yuav tsum huv thiab du. Tsis muaj npuas, pom tseeb khawb, kev nyuaj siab, impurities, xim tsis sib xws, lossis lwm yam tsis xws luag raug tso cai. Qhov kawg ntawm cov yeeb nkab yuav tsum tau txiav smoothly thiab perpendicular mus rau cov yeeb nkab axis.
4. Ntev: Feem ntau ntsuas nrog ib daim kab xev ntsuas. Yuav tsum tsis muaj qhov tsis zoo sib txawv ntawm chav tsev kub.
5. Xim: Cov yeeb nkab yuav tsum yog xim dub lossis xiav. Yam tsawg kawg peb daim kab txaij xiav yuav tsum tau extruded rau ntawm cov yeeb nkab dub, thiab cov kab txaij xim yuav tsum tau muab sib npaug sib npaug ntawm qhov ncig ntawm cov yeeb nkab. Cov kav dej xiav tsuas yog siv rau kev zais zais.
6. Roundness: Feem ntau ntsuas nrog vernier caliper. Rau cov coils lossis cov kav dej ncaj nraim nrog lub nominal txheej kab uas hla ntau dua 710mm, qhov siab tshaj plaws uas tsis yog - roundness tus nqi yog txiav txim los ntawm tus neeg muag khoom thiab tus neeg yuav khoom. Qhov siab tshaj plaws uas tsis yog - roundness tus nqi rau lwm yam specifications yuav tsum tsis txhob tshaj tus qauv yuav tsum tau.
7. Txoj kab uas hla sab nraud thiab phab ntsa tuab: Cov kab uas hla sab nraud feem ntau ntsuas nrog ib txoj kab uas hla π tus kav. Qhov nruab nrab sab nraud ntawm cov yeeb nkab kawg yuav tsum tsis pub tsawg dua 98.5% ntawm qhov ntsuas tus nqi ntawm qhov deb ntawm 1.5dn lossis 300mm ntawm cov yeeb nkab kawg. Lub thickness feem ntau ntsuas nrog phab ntsa thickness micrometer. Yuav tsum tsis muaj qhov tsis zoo sib txawv hauv qhov tuab.
8. Hnub tsim khoom: Hnub tsim cov ncauj lus kom ntxaws yuav tsum tau qhia ntawm cov ntaub ntawv qhia txog cov yeeb nkab.

Zhejiang Qingfa Yeeb Nkab Kev Lag Luam Technology Co., Ltd. tau mob siab rau PE pipeline accessories kev lag luam rau ntau tshaj 20 xyoo. Lub tuam txhab tsuas yog tsim cov PE hluav taws xob fusion yeeb nkab fittings, kub- cov yeeb nkab yaj fittings, pob li qub, steel- cov pob qij txha hloov pauv yas, thiab lwm yam, rau PE roj thiab cov kav dej, npog DN20 rau DN1600, nrog ntau tshaj 3,000 ntau yam thiab specifications.
