1. Nquag xyuas cov anti - Corrosion txheej: ua ntej phab ntsa xim hlau rau cov hlau sib xyaw ua ke rau xeb. Rov thov rov qab {- Cov xim corrosion solosion kom sai yog tias muaj teeb meem pom.
2 Tshawb xyuas lub ru tsev xim hlau phaj rau deformation thiab txi (piv txwv li, kev sib hais plaub ntawm lub ru tsev pob qij txha).
3. Tswj cov tshuab ntsuas AUXiliae: Kos kem txhawb nqa thiab Purlin BRACes rau looseness. Yog tias xoob, ua kom nruj cov bolts tam sim ntawd. Tsis tu ncua cov ntaub ntub dej thiab cua cov khoom siv kom paub tseeb tias du qhib thiab kaw.
4. Zam kev tshaj tawm: khw muag khoom nruj raws li qhov tsim muaj peev xwm thauj khoom muaj peev xwm. Tsis txhob muab cov khoom siv hnyav sib cais (xws li cov khoom siv tsim kho) ntawm lub ru tsev kom tiv thaiv ntev- lub sij hawm overloading thiab deformation ntawm cov hlau sib txuas.
