Kev txhawb nqa cov yeeb nkab niaj hnub no yog tsim los nrog kev tsom mus rau kev sib txuas ntawm kev tsim kho lub cev nrog lub zog siab. Piv txwv li, lawv siv cov qauv hollow lossis cov ntaub ntawv sib xyaw kom txo tau qhov hnyav thaum tswj kev thauj khoom -cov kabmob muaj peev xwm.
Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, precision casting lossis CNC machining technologies txhim kho qhov tseeb qhov tseeb ntawm cov yeeb nkab txhawb nqa, txo cov teeb meem kev teeb tsa. Hauv kev lag luam xws li tshuaj lom neeg thiab lub zog tsim hluav taws xob, kev tiv thaiv corrosion ntawm cov yeeb nkab txhawb nqa ncaj qha cuam tshuam rau kev nyab xeeb ntawm lub cev; Yog li ntawd, cov txheej txheem kho saum npoo (xws li galvanizing thiab hmoov txheej) yog qhov ntsuas tseem ceeb.
Hauv kev siv cov tswv yim, cov yeeb nkab txhawb nqa installation yuav tsum nruj me ntsis ua raws li cov lus qhia tshwj xeeb. Piv txwv li, kho bolts yuav tsum tau nruj symmetrically kom tsis txhob muaj kev nyuaj siab nyob rau hauv lub cheeb tsam; expansion gaps yuav tsum tau muab rau cov yeeb nkab txhawb nqa siv nyob rau hauv insulated pipelines los tiv thaiv kev puas tsuaj vim thermal expansion.
