HDPE yeeb nkab fittings ua haujlwm li cas ntawm qhov kub thiab txias?

Taw qhia:

HDPE Compression Fittings tau tshwm sim los ua ib qho tseem ceeb hauv kev thauj mus los ntawm cov kua dej, hloov cov toj roob hauv pes ntawm cov yeeb nkab txuas thiab kev ruaj ntseg. Qhov kev daws teeb meem siab tshaj no khav theeb ntau cov txiaj ntsig, muab tso rau nws raws li qhov kev xaiv zoo tshaj plaws ntawm ntau hom kev lag luam thiab kev siv.

HDPE yeeb nkab fittings ua tau zoo heev ntawm qhov kub thiab txias. Ntawm no yog ib qho kev sib cais:

Kev kub siab ua haujlwm

Hydrostatic zog

HDPE raj muaj lub zog zoo heev nyob rau hauv qhov kub thiab txias. Piv txwv li, nyob rau hauv qhov kev ntsuam xyuas hydrostatic zog ntawm 80 degree C, HDPE yeeb nkab tuaj yeem kav ntev li 165 teev ntawm qhov kev ntxhov siab ntawm 3.5MPa, lossis 1000 teev ntawm 3.2MPa, thiab tuaj yeem nyob twj ywm tsis tawg thiab tsis tawm.

Thaum tshav kub kub tsis kam thiab oxidation tsis kam

Lub sijhawm oxidation induction ntawm HDPE yeeb nkab ntawm 200 degree ncav cuag tsawg kawg 20 feeb, uas qhia tau hais tias nws zoo heev tshav kub tsis kam thiab oxidation tsis kam, ua kom lub sij hawm ntev kev nyab xeeb ntawm cov yeeb nkab ntawm kub kub.

Txawm li cas los xij, nws tsim nyog sau cia tias qhov kub thiab txias ib puag ncig tuaj yeem ua rau muaj kev laus zuj zus thiab kev ua haujlwm ntawm HDPE cov ntaub ntawv, tshwj xeeb tshaj yog thaum raug kub hnyiab tau ntev. Tsis tas li ntawd, qhov kub thiab txias kuj tseem tuaj yeem ua kom cov evaporation ntawm cov dej hauv cov yeeb nkab, ua rau cov phab ntsa sab hauv ntawm cov yeeb nkab ntxhib, ua kom cov dej tsis kam, thiab txo cov dej ntws.

Tsawg kub ua haujlwm

Tsawg kub cuam tshuam tsis kam

Qhov kub thiab txias embrittlement kub ntawm HDPE yeeb nkab yog tsawg heev, thiab nws yuav siv tau yam xyuam xim nyob rau hauv qhov kub ntawm -60 ~ 60 ° C. Txawm nyob rau hauv lub caij ntuj no kev tsim kho, vim muaj kev cuam tshuam zoo ntawm nws cov ntaub ntawv raw, nws tsis yooj yim los tsim cov yeeb nkab tawg.

Hydrostatic zog

Hauv kev sim hydrostatic zog ntawm 20 degree, HDPE yeeb nkab tuaj yeem kav ntev li 100 teev nyob rau hauv qhov kev ntxhov siab ntawm 8.0MPa, thiab cov yeeb nkab lub cev tsis muaj rupture thiab tsis to.

Txawm hais tias HDPE raj ua tau zoo ntawm qhov kub thiab txias, polyethylene tseem tuaj yeem ua rau muaj kev pheej hmoo ntawm kev tawg ntawm qhov kub qis. Txawm li cas los xij, qhov kev ua tau zoo ntawm qhov kub thiab txias ntawm polyethylene tuaj yeem txhim kho tau zoo los ntawm kev ntxiv qee yam ntawm cov tshuaj tiv thaiv kev cuam tshuam thiab tus neeg sawv cev crosslinking.

Hauv SUMMARY:

HDPE yeeb nkab fittings qhia kev ua tau zoo ntawm ob qho tib si siab thiab qis kub, nrog kev ruaj ntseg zoo thiab ua haujlwm ntev. Txawm li cas los xij, thaum siv nyob rau hauv qhov kub thiab txias ib puag ncig, yuav tsum tau them nyiaj rau cov kev pheej hmoo uas tshwm sim los ntawm kev laus zuj zus thiab kev ua haujlwm tsis zoo ntawm cov yeeb nkab; Ntawm qhov kub thiab txias, txawm hais tias HDPE cov raj muaj qhov cuam tshuam zoo, kev ntsuas yuav tsum tau coj los tiv thaiv kev tawg tuaj yeem tawg.
