Kev xaiv cov hauv paus ntsiab lus ntawm kev tshawb nrhiav tsis muaj kev puas tsuaj rau ntawm qhov chaw ncaj seam steel kav: xaiv cov hmoov hlau nplaum sib nqus, thiab cov kav hlau tsis-hlau hlau nplaum raug xaiv rau kev ntsuas nkag.
Rau vuam cov pob qij txha nrog lub thermal tawg nyiam, qhov tseem ceeb ntawm qhov chaw uas tsis muaj kev puas tsuaj yuav tsum tau ua tom qab vuam thiab kev kho cua sov. Rau vuam cov pob qij txha nrog ncua kev tawg, kev tshawb nrhiav thiab kev tshawb nrhiav yuav tsum tau ua tom qab lub sijhawm ua haujlwm rau lub sijhawm txias rau ib lub sijhawm.
Daim ntawv thov kev tshawb nrhiav qhov chaw tsis muaj kev puas tsuaj yog ua raws li tus qauv yuav tsum tau ua. Cov khoom thiab kev siv ntawm kev tshawb nrhiav tsis muaj kev puas tsuaj rau saum npoo yog feem ntau raws li hauv qab no:
(1) Kev tshuaj xyuas zoo ntawm cov yeeb nkab sab nraud.
(2) Ua kom pom tseeb welded vuam seams ntawm kev kuaj xyuas qhov tsis xws luag.
(3) Kev tshawb pom ntawm qhov tsis xws luag ntawm qhov tseem ceeb ntawm cov ces kaum welds.
(4) Kev tshawb nrhiav qhov tseem ceeb ntawm cov cuab yeej cuab tam vuam thiab ntoo khaub lig-linked tri-teasing ceg tube vuam sib koom ua ke tsis xws luag.
(5) Kev sim tsis zoo ntawm qhov siab-hardening nyiam vuam sib koom ua ke.
(6) Tshawb xyuas cov grooves ntawm cov kav dej tsis muaj kev ncaws pob uas tsis muaj qhov kub ntawm 29 degrees Celsius hauv qab 29 degrees Celsius.
(7) Kuaj qhov kev xeem ntawm ob-sided vuam seams tom qab ntxuav.
