Mwachidule
Ndi luso lathu lotsogola komanso mzimu wathu waluso, mgwirizano, maubwino ndi kukula, tikhala ndi tsogolo labwino limodzi ndi chitoliro chanu chachitsulo chomwe mumachilemekeza, timasunga nthawi yake yobweretsera, mapangidwe apamwamba, apamwamba kwambiri komanso kuwonekera kwa makasitomala athu. ogula. Moto wathu uyenera kukhala wopereka zinthu zabwino munthawi yake.
Takulandilani kudzayendera kampani yathu, fakitale ndi nyumba yathu yosungiramo zinthu zomwe zimawonetsa masheya athu omwe angakwaniritse zomwe mukuyembekezera. Pakadali pano, ndikosavuta kuchezera tsamba lathu, ndipo ogulitsa athu ayesetsa kukupatsani ntchito yabwino kwambiri. Onetsetsani kuti mutilumikizane ngati mukufuna zambiri. Cholinga chathu ndi kuthandiza makasitomala kuzindikira zolinga zawo. Tikuchita khama kwambiri kuti tikwaniritse izi.
Za mpweya zitsulo welded chitoliro, pali mtundu poeple wotchedwa MS chitoliro, kutanthauza mapaipi opangidwa kuchokera wofatsa zitsulo/otsika mpweya zitsulo (mpweya zitsulo kuti mpweya zili m'munsi kuposa 0.25%). Chitoliro chamtunduwu ndichofala kwambiri, chimagwiritsidwa ntchito kwambiri pomanga, scaffold ndi zina zotero. Chitoliro chamtunduwu ndi chofewa, sichingathe kupirira mphamvu zambiri ndi kukakamizidwa, kotero chingagwiritsidwe ntchito poyendetsa madzi otsika. Chifukwa chitsulo chamtunduwu chili ndi katundu wochepa wamakina, sichidzagwiritsidwa ntchitokugwiritsa ntchito zochitika zomwe zimafunikira kwambiri, kotero anthu akatchula chitoliro cha MS, nthawi zonse amatanthauza chitoliro chowotcherera.
Kugwiritsa ntchito
Amagwiritsidwa ntchito makamaka pazigawo zamphamvu ndi zokakamiza, komanso pazolinga zonse za nthunzi, madzi, gasi ndi mapaipi amlengalenga.
