Kev ceev faj rau PE pipeline layout thiab installation

Kev ceev faj rau PE pipeline layout thiab installation

PE yeeb nkab yog cov thermoplastic resin nrog siab crystallinity thiab tsis polarity. Qhov saum npoo ntawm thawj HDPE yog milky dawb, nrog rau qee qhov kev hloov pauv hauv cov ntu nyias. PE muaj kev tiv thaiv zoo rau feem ntau ntawm cov tsev neeg thiab cov khoom siv tshuaj.

Cov yam ntxwv ntawm cov kav dej PE

1. Txhim khu kev sib txuas: Cov txheej txheem hluav taws xob cua sov fusion yog siv los txuas cov kav dej polyethylene, thiab lub zog ntawm cov pob qij txha yog siab dua lub zog ntawm lub raj xa dej.

2. Qhov zoo ntawm qhov kub thiab txias tsis kam: Polyethylene muaj qhov kub tsis tshua muaj siab embrittlement kub thiab tuaj yeem siv nyab xeeb hauv qhov kub ntawm -60 txog 60 ℃. Thaum lub caij ntuj no kev tsim kho, vim muaj kev cuam tshuam zoo ntawm cov ntaub ntawv, cov yeeb nkab tawg yuav tsis tshwm sim.

3. Zoo kev ntxhov siab tawg tsis kam: HDPE muaj qhov qis qis qis, siab shear zog, thiab zoo heev khawb kuj. Nws tseem muaj qhov ua tau zoo ib puag ncig kev ntxhov siab tawg ua haujlwm.

4. Cov tshuaj tiv thaiv corrosion zoo: HDPE kav dej tuaj yeem tiv taus corrosion ntawm ntau yam tshuaj lom neeg, thiab cov tshuaj lom neeg muaj nyob hauv cov av yuav tsis tsim kev puas tsuaj rau cov kav dej. Polyethylene yog ib qho hluav taws xob rwb thaiv tsev, yog li nws yuav tsis pom cov cim ntawm kev lwj, xeb, lossis electrochemical corrosion; Ntxiv mus, nws yuav tsis txhawb kev loj hlob ntawm algae, kab mob, los yog fungi.

5. Kev laus ua haujlwm thiab kev ua haujlwm ntev: cov kav dej polyethylene nplua nuj nyob rau hauv 2-2.5% uniformly faib cov pa roj carbon dub tuaj yeem khaws cia sab nraum zoov lossis siv rau 50 xyoo yam tsis raug mob los ntawm UV hluav taws xob.

Cov teeb meem yuav tsum tau muab sau tseg hauv kev teeb tsa ntawm cov kav dej thiab cov kav dej PE

1. PE faus cov kav dej yuav tsum tsis txhob hla lub tsev lossis cov hauv paus hauv paus. Thaum nws tsim nyog dhau los, lub tsho tiv thaiv lossis lwm yam kev tiv thaiv yuav tsum tau coj los tiv thaiv lub hauv paus;

2. Thaum tso cov kav dej PE hauv qab qhov siab qis ntawm lub hauv paus ntawm cov tuam tsev lossis cov qauv, lawv yuav tsum tsis txhob nyob hauv thaj tsam ntawm lub diffusion lub kaum sab xis raws li compression. Lub kaum sab xis yog feem ntau coj li 45 °;

3. Cov kav dej PE yuav tsum muab tso rau hauv qab ntawm txoj kab khov;

4. Cov neeg nyob hauv cov zej zog, cov chaw ua si, thiab kev lag luam thiab kev lag luam mining tuaj yeem muaj cov kav dej xa dej uas muaj lub npe sab nraud ntawm 200mm los yog tsawg dua nyob ib ncig ntawm lub tsev, thiab qhov kev ncua deb ntawm phab ntsa sab nrauv yuav tsum tsis pub tsawg tshaj 1.00m;

5. Cov kav dej PE raug txwv tsis pub hla dej nag thiab dej phwj tshuaj xyuas qhov dej thiab cov kav dej hauv dej;

Shandong Kungang Hlau Technology Co., Ltd. tshwj xeeb hauv PE cov kav dej thiab cov kav dej PE, ob qho tib si tau dhau los ntawm kev soj ntsuam zoo ntawm lub tuam tsev tswj hwm thiab muaj cov khoom zoo heev. Lub tuam txhab nruj me ntsis ua raws li IS09001: 2008 thoob ntiaj teb kev tswj hwm tus qauv zoo, coj nws cov khoom mus rau qib tshiab. Lub tuam txhab kuj muaj kev tsim thiab kev tsim muaj peev xwm, txuas ntxiv txhim kho cov khoom tshiab, txhim kho cov khoom zoo thiab cov ntsiab lus thev naus laus zis kom tau raws li kev xav tau ntawm kev lag luam. Peb cia siab tias yuav ua haujlwm ua ke thiab tsim kom muaj kev ci ntsa iab!
