1. Thaum lub sij hawm tsim cov txheej txheem ntawm cov yeeb nkab steel, steel phaj deforms tusyees, cov residual kev nyuaj siab yog me me, thiab nto tsis tsim khawb. Cov txheej txheem steel yeeb nkab tau yooj yim dua nyob rau hauv qhov loj ntawm cov yeeb nkab steel nrog txoj kab uas hla thiab phab ntsa tuab, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov hlau qib siab tuab-walled steel kav, tshwj xeeb tshaj yog loj-inch tuab-walled kav. Nws muaj qhov zoo uas lwm cov txheej txheem tsis sib xws. Cov neeg siv muaj ntau qhov yuav tsum tau ua nyob rau hauv cov nqe lus ntawm steel yeeb nkab specifications;

2. Kev siv cov txheej txheem ua ntej vuam thiab tom qab ntawd vuam sab hauv thiab sab nraud (precision vuam), vuam tuaj yeem ua tiav ntawm txoj haujlwm, thiab nws tsis yooj yim kom muaj qhov tsis zoo xws li cov npoo tsis raug, vuam sib txawv, thiab tsis tiav kev nkag mus, thiab nws yog ib qho yooj yim los tswj cov vuam zoo;

3. Lub zuag qhia tag nrho cov neeg kho tshuab nthuav dav tuaj yeem txhim kho qhov tseeb qhov tseeb ntawm cov yeeb nkab steel, thiab txhim kho qhov kev faib tawm ntawm qhov kev ntxhov siab sab hauv ntawm cov yeeb nkab steel, kom tsis txhob muaj kev puas tsuaj vim kev ntxhov siab corrosion thiab tib lub sij hawm txhawb kev siv vuam ntawm qhov chaw;

4. Ua 9 100% kev soj ntsuam zoo ntawm cov kav dej steel, kom tag nrho cov txheej txheem ntawm cov yeeb nkab steel yog nyob rau hauv kev tshuaj xyuas thiab kev saib xyuas zoo, thiab lav tau qhov zoo ntawm submerged arc welded steel kav;

5. Tag nrho cov khoom siv ntawm tag nrho cov kab ntau lawm muaj kev ua haujlwm ntawm kev sib txuas nrog lub khoos phis tawj cov ntaub ntawv nrhiav tau kom paub txog cov ntaub ntawv xa mus rau lub sijhawm. Lub hauv paus tswj chav sau cov kev ntsuas tsis zoo thiab cov ntsuas zoo hauv cov txheej txheem tsim khoom.
