Cov kav dej polyethylene kov yeej qhov tsis zoo ntawm cov kav dej galvanized thiab cov kav hlau cam, uas yooj yim rau xeb, nplai, yug kab mob, thiab muaj lub neej luv luv. Lawv muaj cov yam ntxwv ntawm kev txhim khu kev qha zoo, kev ua haujlwm zoo, kev saib xyuas yooj yim, thiab tus nqi qis. Cov txheej txheem yog tsim nyog rau kev ncaj-faus thiab zais-faus pipelines, zoo daws qhov teeb meem ntawm kev sib koom ua ke. Cov yeeb nkab diameters txawv ntawm dn25, dn63, dn100, dn160, dn200, dn315, dn400 txog dn500, dn630.
Kev tshuaj xyuas cov yam ntxwv ntawm PE yeeb nkab
1. Lub cev zoo heev. Cov kav dej polyethylene tuaj yeem tsis tsuas yog tuav lub rigidity thiab lub zog ntawm high-density polyethylene, tab sis kuj muaj kev yooj yim thiab nkag tau zoo, thiab ntau dua-density polyethylene muaj qhov kub-kua sib txuas kev ua tau zoo, uas yog qhov zoo rau kev txhim kho cov kav dej yas.
2. Anti-corrosion, tsis muaj scaling. Polyethylene dej xa dej yeeb nkab yog cov khoom siv polymer nrog cov qauv tsis muaj polar. Nws muaj qhov zoo ntawm kev tiv thaiv acid thiab alkali corrosion, tsis muaj xeb, tsis muaj scaling, tsis muaj kev laus, tsis muaj kev yug me nyuam ntawm cov kab mob, thiab tsis muaj ntxhiab tsw. Nws yog cov kav dej zoo tagnrho.
3. Zoo toughness, yooj. Polyethylene yeeb nkab yog ib hom high-tughness yeeb nkab, uas muaj zog adaptability rau tsis sib haum xeeb, misalignment thiab deformation ntawm cov yeeb nkab foundation. Kev xyaum hauv tsev thiab txawv teb chaws tau ua pov thawj tias cov kav dej PE yog cov kav dej uas muaj kev ua haujlwm zoo tshaj plaws.
4. Kev ncig yog loj thiab kev lag luam. Sab hauv phab ntsa ntawm cov yeeb nkab polyethylene yog du thiab tsis muaj av. Piv nrog cov kav hlau hlau, PE kav dej tuaj yeem txo cov peev txheej engineering los ntawm ib feem peb, thiab cov kav dej me me tuaj yeem coiled los txo cov nqi engineering ntxiv.
5. Kev sib txuas yog yooj yim, kev tsim kho yog yooj yim, thiab cov txheej txheem yog ntau yam. PE yeeb nkab lub cev yog lub teeb hauv qhov hnyav, nqa tau yooj yim, yooj yim rau vuam, thiab muaj qhov sib txuas tsawg dua. Thaum lub raj xa dej ntev, nws tuaj yeem muab tso rau hauv coil. Cov kev cai rau PE yeeb nkab trench yog qis dua li cov yeeb nkab steel yeeb nkab. Thiab nyob rau hauv cov ntaub ntawv ntawm kev tsim kho tsawg, hluav taws xob fusion vuam siv tau.
6. Lub teeb nyhav. Nws tsuas yog ib feem kaum ntawm cov yeeb nkab steel, uas txo qis kev tsim kho lub zog ntawm cov neeg ua haujlwm thiab txo tus nqi ntawm cov tshuab hoisting.
7. Lub neej ntev, yooj yim rau rov ua dua. Cov kav dej polyethylene muaj lub neej ua haujlwm txog li 50 xyoo, yooj yim rau kev rov ua dua tshiab, thiab tsis tsim cov tshuaj uas cuam tshuam rau ib puag ncig. Cov cuab yeej siv los ua kom paub tab thiab txhim kho tas li.
8. Nws muaj zog adaptability rau hauv av hloov. Polyethylene yeeb nkab yog ib hom high toughness yeeb nkab, nws elongation ntawm tawg yog feem ntau saum toj no 50 feem pua, nws muaj zog adaptability rau tsis sib haum ntawm cov yeeb nkab puag, thiab muaj zoo kuj rau lub hauv paus kev sib hais haum thiab kawg load.
9. Kev saib xyuas yooj yim, dej tsis nres, kev kho roj thiab kev teeb tsa. Nws yog ib qho yooj yim los tswj, thiab tuaj yeem tswj tau thiab nruab yam tsis muaj dej thiab roj.
10. Nws muaj kev tiv thaiv zoo rau kev ntxhov siab tawg. Lub incision rhiab heev ntawm polyethylene yeeb nkab yog tsawg, ib puag ncig kev nyuaj siab kuj yog heev zoo, thiab tej yam kuj nyob rau hauv qis kub yog zoo.
