Thaum lub sij hawm kev thauj mus los, vuam, thiab siv hluav taws xob fusion fittings, nws yog ib qho tsim nyog yuav tsum tau ntsib teeb meem me me. Nws yog ib qho kev txaj muag ncaj qha rau cov hluav taws xob fusion yeeb nkab fittings thaum muaj teeb meem tshwm sim. Puas muaj lwm txoj hauv kev los daws qhov teeb meem?
1. Cov dej ntws tawm ntawm qhov sib txuas ntawm cov hluav taws xob fusion yeeb nkab fittings yog ib qho teeb meem tshwm sim, thiab muaj ntau yam uas tuaj yeem ua rau muaj teeb meem no. Ib zaug xau tshwm sim. Peb tuaj yeem thaiv yooj yim thiab raws li kev tsim kho, pib los ntawm thawj kauj ruam dua nrog hluav taws xob fusion thiab kub yaj vuam, tsis tas yuav khawb cov khoom.
Thaum muaj kev puas tsuaj loj rau cov tsos, cov yeeb nkab puas tuaj yeem raug txiav tawm. Thaum txiav, lawv yuav tsum tiaj tus thiab hloov nrog cov khoom ntawm tib txoj cai thiab hom. Cov khoom lag luam tuaj yeem txuas nrog hluav taws xob fusion, kub fusion, lossis flange. Lub tes tsho kawg yuav tsum tau txuas nrog flange thiab hluav taws xob fusion lub tes tsho, thiab kev sib txuas kub fusion tsis raug tso cai.
3. Yog tias qhov kev sib haum xeeb ntawm lub hauv paus thiab cov khoom puas tsuaj tshwm sim los ntawm kev hloov ntawm ib puag ncig qhov kub thiab txias tau kuaj pom thiab cov phab ntsa sab hauv tsis zoo thiab cov deformation tuaj yeem kho, tom qab kho, nws tuaj yeem siv txuas ntxiv mus. Txawm li cas los xij, qee qhov kev ntsuam xyuas kev nyab xeeb yuav tsum tau ua kom muaj kev nyab xeeb.
4. Yog hais tias qhov hluav taws xob fusion ib feem ntawm qhov kev sib txuas yooj yim ntawm lub qhov (socket) hom roj hmab nplhaib puas, ncaj qha txiav tawm qhov puas ntawm cov kav dej, hloov nws nrog cov khoom tshiab, thiab txuas nrog ob lub qhov (socket) thiab lub tes tsho hloov tau siv.
5. Lub deformation tshwm sim los ntawm qhov muaj zog rub thiab khoov thaum lub sij hawm kev thauj mus los ntawm hluav taws xob fusion raj yuav tsum tau soj ntsuam los txiav txim seb lawv puas tuaj yeem siv tau. Cov uas muaj deformation tseem ceeb yuav tsum tsis txhob siv.
Thaum lub sij hawm kev thauj mus los thiab kev teeb tsa ntawm cov hluav taws xob fusion tubes, nws yog ib qho inevitable uas tej zaum yuav muaj teeb meem. Kev kawm cov kev kho mob tuaj yeem pab peb rov qab poob.
