Kev tsim thiab kev siv cov yeeb nkab yas hauv Suav teb muaj keeb kwm ntau dua 40 xyoo, tshwj xeeb tshaj yog txij li xyoo 1980s, kev siv cov yeeb nkab yas hauv nroog engineering thiab kev tsim kho engineering tau ua rau muaj kev vam meej, tsis yog tsuas yog muaj ntau, tab sis kuj nyob rau hauv ntau yam thiab specifications. tau tsim kho zoo heev. Tshwj xeeb tshaj yog muaj kev nyab xeeb thiab tsis muaj tshuaj lom PE cov kav dej. PE yeeb nkab yog ib hom yeeb nkab uas muaj zog heev, nws txoj kev loj hlob ntawm pob txha yog ntau tshaj 500 feem pua. Qhov yooj yim ntawm cov yeeb nkab PE ua rau nws zoo heev rau kev khoov, thiab kev tsim vaj tse tuaj yeem hla ntau yam teeb meem los ntawm kev hloov cov kev taw qhia ntawm cov kav dej. Feem ntau, qhov toughness ntawm lub raj xa dej tuaj yeem txo cov yeeb nkab fittings thiab txo tus nqi installation. PE yeeb nkab muaj kev cuam tshuam zoo heev thiab av qeeg ua haujlwm.
PE cov yeeb nkab dej muaj qhov zoo nkauj sab hauv, du sab hauv thiab cov yam ntxwv uas tsis yog adhesion los xyuas kom meej tias PE yeeb nkab muaj peev xwm kis tau tus mob ntau dua li cov yeeb nkab ib txwm siv, tab sis kuj txo cov raj xa dej siab thiab cov dej xa hluav taws xob, kom ua tiav. kev siv dej zoo dua thiab cov dej ntws tawm. PE yeeb nkab fittings thiab cov kav dej feem ntau yog txuas nrog kub yaj lossis hluav taws xob yaj, qhov tseem ceeb ntawm kev tswj xyuas kev sib koom ua ke ntawm cov khoom siv sib txuas, cov qauv thiab cov yeeb nkab nws tus kheej, paub txog kev sib koom ua ke ntawm kev sib koom ua ke thiab cov yeeb nkab, uas tuaj yeem tiv thaiv kev ntxhov siab los ntawm sab hauv, thiab tsis muaj kev txhawj xeeb txog cov dej xau thiab huab cua.
