Qhov kub-kub telescopic cua duct siv steel hlau raws li lub cev pob txha thiab yas (nylon) ntaub ua cov yeeb nkab lub cev. Nws yog yoog raws hauv telescopic dabtsi yog khoov thiab kev sib txuas, lub teeb hauv qhov loj thiab yooj yim nqa. Nrog rau cov khoom siv cua, nws yog siv rau kev siv cov pa khib nyiab hauv kev tsim kho ntawm qhov chaw kaw thiab ntev thiab lwm qhov chaw huab cua hnyav.
Qhov kub-resistant telescopic cua duct yog ua los ntawm steel hlau qhwv nrog yas roj hmab pob txha raws li cov pob txha, thiab cov txiv kab ntxwv yas mesh daim ntaub yog siv los ua cov yeeb nkab lub cev. Muaj cov hlua khi ntawm ob qhov kawg ntawm cov yeeb nkab qhov ncauj kom yooj yim rau lub qhov (socketing) ntawm lub qhov hluav taws xob cua. Muaj ib lub nplhaib hlau dai txhua ib 'meter' ntawm lub cev yeeb nkab. Nws yog ib qho yooj yim los txhim kho cov pa duct, cov khoom yog hloov tau thiab khoov, pub dawb rau kev sib txuas, lub teeb loj, yooj yim nqa, kub resistant, acid thiab alkali resistant, nplaim retardant thiab insulating.
Kev kub siab telescopic cua ducts thiab cov khoom siv cua tshuab tau dav siv hauv huab cua, tso pa tawm, thiab tshem tawm plua plav hauv qhov chaw ua haujlwm hnyav xws li chav tshuab, hauv qab daus, tunnels, cov kav dej hauv nroog, kev saib xyuas hauv av hauv av, kev tsim khoom siv nkoj nkoj, kev tua hluav taws thiab pa taws. tso pa tawm. Nws kuj yog ib qho tseem ceeb xaiv rau portable suction kiv cua.
