SSAW Pipe API Spec 5L (PSL2) For Natural Gas Pipe
Ku Cangzhou Spiral Steel Pipes Group Co., Ltd., ndife onyadira kuwonetsa kupambana kwathu kwaposachedwa pamakampani azitsulo -Mtengo wa SSAW.Zopangira zatsopanozi zimaphatikiza ukadaulo wotsogola ndi ukatswiri wosayerekezeka kuti upereke mayankho osasunthika pamagwiritsidwe osiyanasiyana.
SSAW chitoliro ndiwozungulira welded chitolirozopangidwa kuchokera kuzitsulo zazitsulo zapamwamba kwambiri.Timagwiritsa ntchito ukadaulo wapamwamba wa extrusion kuonetsetsa kutentha kosasinthasintha panthawi yonse yopangira, kenako timawotcherera mawaya awiri mbali ziwiri.Ukadaulo wosamalawu umatsimikizira mgwirizano wolimba komanso wokhazikika, zomwe zimapangitsa chitoliro cholimba komanso chodalirika.

Chimodzi mwazabwino kwambiri zachubu chozungulira chozungulirandi mphamvu yake yapamwamba, yomwe imaposa chitoliro chowongoka cha msoko.Izi zimapangitsa kuti zikhale zabwino pama projekiti omwe amafunikira kukhazikika kwadongosolo.Kuphatikiza apo, chifukwa cha kupanga kwake kwapadera, chitoliro chowotcherera chozungulira chimatha kupangidwa pogwiritsa ntchito zitsulo zocheperako, zomwe zimalola kupanga mapaipi akulu akulu.Kuphatikiza apo, pogwiritsa ntchito zosasoweka za m'lifupi womwewo, titha kupanga machubu a mainchesi osiyanasiyana mosasamala, kukulitsa kusinthasintha kwake.
Podzipereka kwambiri pazabwino, kampani yathu yayika ndalama zambiri pakukhazikitsa malo opangira zinthu zamakono.Kampaniyi ili ndi malo okwana 350,000 square metres ndipo ili ndi chuma chonse cha yuan 680 miliyoni.Koma chomwe chimatisiyanitsa ndi gulu lathu lodzipereka.Ogwira ntchito athu a 680 aluso kwambiri ndi omwe amachititsa kuti tipambane.
Timanyadira mphamvu yathu yopanga pachaka ya matani 400,000 a machubu achitsulo ozungulira, kupitilira miyezo yamakampani.Kutulutsa kosayerekezeka kumeneku kwapanga mtengo wokwera kwambiri wa yuan biliyoni 1.8.Gulu lathu lakhama limawonetsetsa kuti chipangizo chilichonse chomwe chimachoka pamalo athu chimatsatira njira zoyendetsera bwino kwambiri, zomwe zimatsimikizira makasitomala athu kukhala abwino kwambiri.
Mwachidule, spiral submerged arc welded mapaipi ndi masewera kusintha makampani zitsulo chitoliro.Ndi mphamvu zake zapamwamba, kusinthasintha kwapadera komanso kudalirika kosayerekezeka, ndiye yankho lomaliza pazofunikira zanu zonse zamapaipi.Gwirizanani ndi Cangzhou Spiral Steel Pipes Group Co., Ltd. lero kuti mukumane ndi tsogolo la mafakitale achitsulo.
