Txheej txheem ciav hlau rau cov khoom siv rau cov hlau ciav hlau thiab cov yeeb nkab uas tsis txuas rau lub cav ntim ntawm cov hlau ciav hlau, -qhov-chaw-muab pob zeb.

Ntau lub tsev loj siv kauv vuam fais fab hauv lub hauv paus tob, qhov seem hauv qab. Yog tias SSAW welded steel yeeb nkab siv, ces nws tau tsav mus rau hauv av los ntawm lub cav loj thiab yuav ntim nrog cov pob zeb tom qab nws qhov khoom siv los txhawm rau tiv thaiv cov yeeb nkab thiab ua rau nws tseem sturdier. Hom kab yeeb nkab no feem ntau ruaj ruaj thiab tsis khoov ntawm kev ntxhov siab yooj yim, yog li nws yog qhov tsim nyog rau qhov tob tob.
