Kamupani Tulaga

O loʻo i totonu o le fatu o Cangzhou City, Hebei Province, o le kamupani o se taʻitaʻi i le gaosiga o paipa uelo talu mai lona faavaeina i le 1993. O le fale e aofia ai se vaega o le 350,000 sikuea mita ma ua faʻapipiʻiina i masini ma tekonolosi e gaosia muamua- vasega oloa e ausia tulaga fa'avaomalo. Faatasi ai ma le aofaʻi o aseta o le RMB 680 miliona ma le 680 tagata faigaluega faʻapitoa, o loʻo tuʻuina atu le kamupani i le tulaga lelei i itu uma o ana galuega.

FAQ

Q1. O le a le Submerged Arc Welding (SAW)?

O le SAW o se faiga faʻapipiʻi e faʻaogaina ai le faʻaogaina o le eletise faʻaauau ma se vaega o le fusible flux granular e puipuia ai le uelo mai le faʻaleagaina. O lenei metotia e sili ona aoga i mea mafiafia ma e fetaui lelei mo paipa kesi masani.

Q2. Aisea e sili atu ai le SAW mo paipa ueloina?

O tekonolosi SAW e maua ai le loloto o le ulu ma le lamolemole, e taua tele i le faʻatulagaina o le faʻamaonipaipa fa'afefeteinafa'aaogaina i fa'aoga maualuga e pei o felauaiga kasa masani.

Q3. O le a le aoga o le faʻaaogaina o tekonolosi paipa faʻapolofesa?

O auala faʻapitoa faʻapipiʻi faʻapitoa e faʻamautinoa ai le lelei faifaipea, faʻaitiitia le lamatiaga o faʻaletonu ma faʻaleleia le faʻatinoga atoa o oloa faʻapipiʻi, lea e taua i totonu o se pisinisi saogalemu.

Q4. E fa'apefea ona fa'amautinoa e lau kamupani le lelei o le fa'agasologa o le uelo?

O la matou kamupani o loʻo tausisia faiga faʻapitoa e pulea lelei ma faʻafaigaluegaina tagata tomai faʻapitoa e aʻoaʻoina i auala fou uelo, e aofia ai le SAW, ina ia mautinoa o oloa taʻitasi e fetaui ma le saogalemu ma tulaga faʻatinoga.
