Kev ua haujlwm Extrusion yuav tsum tau ua thaum tsim cov khoom siv PE

Thaum lub sij hawm tsim cov khoom siv PE yeeb nkab, kev ua haujlwm extrusion yuav tsum tau ua. Yog tias cov ntsiab lus dej hauv cov khoom muaj siab, uas txhais tau hais tias qhov ntub dej yog qhov siab, kuj tseem yuav muaj teeb meem nrog nws txoj haujlwm extrusion, yog li ntawd lub tshuab ziab khaub ncaws ua ntej siv tuaj yeem nqa tawm kom tshem tawm cov ntub dej ntawm cov khoom. Ntxuav cov yeeb nkab fittings thiab siv lub tshuab ob tog trimming los txiav lub ntsej muag kawg ntawm ob lub welded pob qij txha. Tom qab ntawd, muab cov yeeb nkab tso rau ntawm cov khoom siv fusion welding thiab siv lub thruster kom ob lub yeeb nkab kawg tuaj rau hauv kev sib cuag. Txheeb xyuas qhov sib xws ntawm ob qhov chaw thiab thawb cov yeeb nkab hauv qab lub siab uas tau teev tseg.
Thaum lub caij ntuj no kev tsim kho, vim muaj kev cuam tshuam zoo ntawm cov khoom siv thaum lub sij hawm tsim khoom, cov yeeb nkab tawg yuav tsis tshwm sim. Txawm li cas los xij, tsis txhob siv cov kav dej PE ua cov kav dej kub vim tias lawv tuaj yeem tiv taus qhov kub ntawm 60 degree, uas yog qhov tsis ncaj ncees lawm thiab ua haujlwm ntev ntev.
Gas muaj cov khoom nram qab no uas muaj txiaj ntsig zoo rau kev ntsuas siab ntawm cov kav dej PE: 1. Vim qhov tsis ruaj khov ntawm cov pa nruab nrab. Ntxiv mus, nws yooj yim rau compression thiab ncab, thiab qhov ntim ntawm cov roj sib txawv nyob ntawm qhov loj ntawm qhov chaw: thaum cov roj nkag mus rau hauv PE pipeline, nws yuav ua rau tag nrho qhov chaw. Vim tias tag nrho ntev ntawm PE kav tsis raug txiav tom qab tsim khoom, nws kuj yog qhov yooj yim rau kev tsim kho thiab siv yav tom ntej. Thiab thaum lub sij hawm tsim kho cov kav dej PE, cov txheej txheem docking tsim nyog yuav raug siv rau cov yeeb nkab tso thiab docking ua haujlwm.
High elastic PE yeeb nkab dej xa dej yog ib hom khoom siv yeeb nkab siab, nrog rau cov pob txha elongation ntawm ntau dua 500 feem pua ​​​​ntawm kev tsim khoom. Nws muaj lub zog yoog raws qhov tsis sib xws ntawm cov yeeb nkab hauv paus thiab yog lub raj xa dej nrog kev ua tau zoo ntawm seismic. Cov cua txias thiab sizing system nyob rau hauv cov yeeb nkab ntau lawm kab kuj yog ib qho tseem ceeb ntawm cov yeeb nkab extrusion ntau lawm kab. Nws qhov kev ua tau zoo cuam tshuam ncaj qha rau kev ua haujlwm ntawm tag nrho cov kab ntau lawm, cuam tshuam rau kev tsim khoom thiab qhov zoo ntawm cov kav dej sab hauv thiab sab nrauv.
