Thermal expansion yeeb nkab yog steel yeeb nkab ua tshwj xeeb txoj kev yog ib tug kub expanding kev siv ntawm hydraulic los yog txhua yam txhais tau tias hais kom cov hlau yeeb nkab los ntawm cov hlau phab ntsa raws lub radially sab nraud dilatation molding siab ua technology. Mechanical txhais tau tias tshaj li hydraulic txoj kev, pab kiag li lawm, yooj yim thiab ntau lub hwj chim nyob rau hauv lub ntiaj teb no tus ua nws tus kheej ob peb loj-caliber seam welded yeeb nkab expanding txheej txheem tswj yog xaiv.

Ib txoj kev ua ntawm thermal expansion yeeb nkab, yog cov yeeb nkab me me uas ua cov yeeb nkab loj. Thermal expansion yeeb nkab kub-kuav los tiag steel mechanical zog tshaj qhov me ntsis. Txwv rau tus qauv steel seamless steel raj yog txwv, raws li qhov kawg-cov neeg siv khoom xav tau thermal expansion yeeb nkab yog li nws tau yug los, thermal expansion yeeb nkab arbitrary qauv qauv kuj loj, feem ntau raws li cov neeg siv khoom xav tau thiab tsim, thermal expansion yeeb nkab yog, peb Feem ntau hais tias thermal expansion ntawm cov yeeb nkab, qhov ceev yog qhov tsawg, tab sis luv luv steel yeeb nkab muaj zog, (seamless steel yeeb nkab) tuaj yeem hu ua thermal expansion.
