Qhov saum npoo ntawm lub nplhaib kauv yog welded nrog ob peb lub cones, thiab cov kev taw qhia ntawm lub taub ntawm lub semi cones yog downward extension kev taw qhia ntawm lub hauv paus axis ntawm lub nplhaib kauv. Lub semicones taw qhia downwards tuaj yeem muab lub zog ntau dua thaum ntsia hlau rau hauv, ua rau cov ntsia hlau zoo dua. Thaum rub tawm, qhov chaw hauv qab ntawm semi cones plays lub luag haujlwm thaiv thiab muaj zog tiv thaiv kom rub tawm.
Raws li hom tshiab ntawm lub hauv paus tshuab, nws muaj cov yam ntxwv ntawm kev yooj yim installation, yooj yim, siv sij hawm luv luv, tsis tshua muaj kev vam khom rau cov khoom siv dej, kev cuam tshuam me me los ntawm kev hloov ib puag ncig, tsis muaj kev puas tsuaj rau cov av ib puag ncig, yooj yim rov qab, thiab tsiv teb tsaws. Nws daim ntawv thov Scope yog maj expanding.
Yuav ua li cas muaj pes tsawg xyoo ib tug kauv pawg uas tau screwed nyob rau hauv? Nws puas yuav corrode sai? Qhov kev txhawj xeeb no yog qhov tsis tsim nyog kiag li. Ua ntej, cov kauv pawg yog screwed rau hauv av thiab nyob rau hauv kev sib cuag nrog cov av. Muaj huab cua tsawg heev nyob nruab nrab ntawm lawv, thiab tsis muaj oxygen, hlau yuav tsis oxidize, ua rau lub ntuj poob qis heev. Thib ob, cov kauv pawg tsim los ntawm Yichen Tuam Txhab siv cov tshuab kub-dip galvanizing, uas muaj kev tiv thaiv corrosion zoo heev. Txawm tias tom qab 75 xyoo ntawm kev siv hauv av, lawv tseem muaj kev ua tau zoo.
