3PE anti-corrosion steel yeeb nkab cov ntaub ntawv muaj xws li seamless steel kav, kauv steel kav thiab ncaj seam steel kav. Peb-txheej polyethylene (3PE) anti-corrosion txheej tau dav siv nyob rau hauv cov roj pipeline kev lag luam vim nws zoo corrosion kuj, dej vapor permeability kuj thiab txhua yam khoom.
Cov txheej txheem tiv thaiv corrosion ntawm 3PE tiv thaiv corrosion steel kav yog qhov tseem ceeb rau lub neej ntawm cov kav dej faus. Qee cov kav dej ntawm cov khoom siv tib yam yuav tsis corrode tom qab faus rau hauv av tau ntau xyoo lawm, thaum lwm tus yuav tawm hauv ob peb xyoos. Nws yog vim tias lawv siv cov txheej txheem sib txawv los tiv thaiv corrosion.
Hlau yeeb nkab sab nrauv phab ntsa tiv thaiv corrosion
3PE anti-corrosion feem ntau muaj 3 txheej ntawm cov qauv:
The first layer of epoxy powder (FBE>100 hli)
Qhov thib ob txheej ntawm cov nplaum (AD) 170 ~ 250um
Peb txheej ntawm polyethylene (PE) 1.8 ~ 3.7mm
Hauv kev ua haujlwm tiag tiag, peb cov ntaub ntawv sib xyaw thiab sib xyaw ua ke rau hauv ib qho, thiab tom qab ua tiav, lawv tau ruaj khov ua ke nrog cov yeeb nkab steel los tsim cov txheej txheem tiv thaiv corrosion zoo heev. Nws txoj kev ua haujlwm feem ntau muab faib ua ob hom: hom winding thiab round tuag npog hom.
Cov txheej txheej ntawm 3PE tiv thaiv corrosion steel yeeb nkab yog cov txheej hauv qab yog nyob rau hauv kev sib cuag nrog cov yeeb nkab steel nto thiab yog epoxy hmoov txheej txheej, thiab cov txheej txheem nruab nrab yog cov nplaum copolymer nrog cov ceg ua haujlwm ua haujlwm. Cov txheej txheej saum npoo yog high-density polyethylene anti-corrosion txheej.
Triple PE anti-corrosion txheej ua ke nrog lub siab impermeability thiab siab mechanical zog ntawm epoxy resin thiab polyethylene cov ntaub ntawv. Txog tam sim no, nws tau lees paub thoob ntiaj teb tias yog qhov zoo tshaj plaws thiab ua haujlwm zoo tshaj plaws ntawm cov kav dej los tiv thaiv corrosion txheej, thiab tau siv ntau yam haujlwm.
