Ssaw Pipe API SCICE 5L (PSL2) ya chibadwa cha gasi

Kufotokozera kwaifupi:

Tsatanetsatane wazogulitsa

Matamba a malonda

Ku Cangzhou Studel Steel Mapaipes Guation Co., Ltd., ndife onyada kwambiri kufotokozerana za kuwonongeka kwathu kwaposachedwa mu malonda achitsulo -Chitoliro cha SSAW. Chojambula chatsopanochi chikuphatikiza ukadaulo wodulira wodulidwa ndi ukadaulo wosayerekezeka kuti upatse njira zosasangalatsa zothetsera zinthu zosiyanasiyana.

Chitoliro cha SSAW ndichitoliro chowalazopangidwa kuchokera ku ma strip matrip chitsulo choyipa. Timagwiritsa ntchito ukadaulo wapamwamba kuti tiwonetsetse kutentha kosalekeza kosintha konse kopanga, kenako ndikuwotcha kaya. Tekinoloje yodziwika bwino iyi imatsimikizira cholumikizira komanso cholimba, chomwe chimapangitsa chitoliro cholimba komanso chodalirika.

Imodzi mwa zabwino zambirichubu chowalaMphamvu zake zazikulu, zomwe zimaposa chitoliro chowongoka. Izi zimapangitsa kukhala koyenera kwa ntchito zomwe zimafuna kukulitsa umphumphu. Kuphatikiza apo, chifukwa cha kupanga kwake kosiyana, chitoliro chowoneka bwino chimatha kupangidwa pogwiritsa ntchito ma billets achitsulo, kulola kupanga mapaipi akuluakulu kwambiri. Kuphatikiza apo, pogwiritsa ntchito zakumapeto kwa zaka zomwezi, titha kupanga machubu osiyanasiyana, kukulitsanso zinthu zosiyanasiyana.

Ndi kudzipereka kwamphamvu kwa mtundu, kampani yathu yakhazikitsa zida zazikulu pakukhazikitsa malo opangira ndege. Kampaniyo imakwirira malo a mita 350,000 ndipo ili ndi zinthu zonse za yun 680 miliyoni. Koma zomwe zimatisiyanitsitsa ndi gulu lathu lodzipereka. Ogwira ntchito azaka 680 ogwira ntchito bwino kwambiri ndi omwe amayendetsa zomwe tikuchita bwino.

Timanyadira kuti tikhala ndi mwayi wa matani 400,000 a machubu a spil, oposa akatswiri opambana. Kutulutsa kosayerekezereka kumeneku kwapanga mtengo wokwera kwambiri wa 1.8 biliyoni Yuan. Gulu lathu lakhali limawonetsetsa kuti chida chilichonse chomwe chimasiya ntchito yathu chimatsatira njira zowongolera kwambiri, ndikutsimikizira makasitomala athu kukhala apamwamba kwambiri.

Chidule Ndi mphamvu zake zazikulu kwambiri, kutanthauzira kosinthana kwakukulu komanso kudalirika kosayerekezeka, ndiye yankho lalikulu kwambiri pazofunikira zanu zonse. Gwionana ndi Cangzhou stal steel mapaipes Guation Co., Ltd. Lero kuti mumve zamtsogolo mwa malonda achitsulo.
