SSAW Pipe Spec 5L (PSL2) Yepaipi Yegasi Rakasikwa
KuCangzhou Spiral Steel Pipes Group Co., Ltd., tinodada zvikuru kuratidza budiriro yedu yazvino muindasitiri yepombi yesimbi -SSAW pombi.Ichi chigadzirwa chitsva chinosanganisa tekinoroji yekucheka nehunyanzvi husingaenzaniswi kuti ipe mhinduro dzisina musono kune dzakasiyana siyana dzekushandisa.
SSAW pombi ispiral welded pipeyakagadzirwa kubva kumhando yepamusoro simbi coils.Isu tinoshandisa advanced extrusion tekinoroji kuona tembiricha inowirirana mukati mese maitiro ekugadzira, uye tobva taita otomatiki kaviri-waya-yakapetwa-mativi akanyudzwa arc welding.Iyi tekinoroji yehunyanzvi inovimbisa chisungo chakasimba uye chakasimba, zvichikonzera pombi yakasimba uye yakavimbika.

Imwe yemabhenefiti akakosha espiral welded chubhuisimba rayo repamusoro, rinopfuura iro remusono wakatsetseka wepombi yakasungwa.Izvi zvinoita kuti ive yakanakira mapurojekiti anoda kuvandudzwa kwechimiro chekuvimbika.Uye zvakare, nekuda kweiyo yakasarudzika nzira yekugadzira, spiral welded pombi inogona kugadzirwa uchishandisa yakamanikana simbi mabheti, ichibvumira kugadzirwa kwemapaipi makuru dhayamita.Pamusoro pezvo, nekushandisa ma blanks ehupamhi hwakafanana, tinokwanisa kugadzira machubhu emadhayamita akasiyana, tichiwedzera kuwedzera kugona kwayo.
Nekuzvipira kwakasimba kune mhando, kambani yedu yakaisa zvakakosha zviwanikwa mukumisikidza-ye-iyo-art yekugadzira zvivakwa.Iyo kambani inovhara nzvimbo inosvika 350,000 square metres uye ine yakazara midziyo ye680 miriyoni yuan.Asi chinonyatsotisiyanisa ichikwata chedu chakazvipira.Vashandi vedu ve680 vane hunyanzvi hwepamusoro-soro ndivo vanotikurudzira kubudirira kwedu.
Isu tinodada nehuwandu hwedu hwegore hwekugadzira hwe400,000 matani espiral simbi chubhu, inodarika zviyero zveindasitiri.Izvi zvisingaenzaniswi zvakabuda zvakagadzira kukosha kwakanyanya kweiyo 1.8 bhiriyoni yeyuan.Chikwata chedu chakashinga chinoona kuti chishandiso chese chinobuda panzvimbo yedu chinoomerera kumatanho akasimba ekutonga, kuvimbisa vatengi vedu mhando yepamusoro.
Muchidimbu, spiral yakanyura arc welded mapaipi ishanduko yemutambo weindasitiri yesimbi pombi.Nesimba rayo repamusoro, kuita kwakasiyana-siyana uye kuvimbika kusingaenzaniswi, ndiyo yekupedzisira mhinduro kune ako ese welded pombi zvinodiwa.Batira pamwe neCangzhou Spiral Steel Pipes Group Co., Ltd. nhasi kuona ramangwana reindasitiri yesimbi pombi.
