S235 J0 Spiral Steel Pipe - Kuchita Kwabwino Kwambiri Kwa Chitoliro Chachikulu Chachikulu Chowotcherera

Kufotokozera Kwachidule:

Gawo ili la European Standard limatchula zaukadaulo woperekera magawo oziziritsa opangidwa ndi welds, magawo opanda dzenje a mawonekedwe ozungulira, masikweya kapena amakona anayi ndipo amagwira ntchito ku magawo amphako omwe amapangidwa ozizira popanda kutenthedwa pambuyo pake.

Cangzhou Spiral Steel Pipes Group Co., Ltd imapereka gawo lopanda kanthu la mipope yachitsulo yozungulira.

Ndife onyadira kuyambitsa mankhwala athu apamwamba kwambiri,S235 J0 Spiral Chitoliro chachitsulo, yopangidwa kuti ikwaniritse zosowa zamakampani osiyanasiyana.Monga opanga otsogola m'munda, timagwiritsa ntchito ukadaulo wapamwamba komanso ukatswiri kuti tipange zapamwamba kwambirichitoliro cha mzere ndi kulimba kwapadera ndi magwiridwe antchito.

Mapaipi athu ozungulira achitsulo amapangidwa kuchokera ku ma coil achitsulo opangidwa ndi ma waya awiri mbali ziwiri zowotcherera arc.Kudzera nthawi zonse kutentha extrusion akamaumba luso, timaonetsetsa kuti chubu aliyense amapangidwa ndi mwatsatanetsatane kwambiri ndi kugwirizana.Kupanga mwaluso kumeneku kumatsimikizira kuti zogulitsa zathu zimakwaniritsa miyezo yapamwamba kwambiri, zomwe zimawapangitsa kukhala abwino kwambiri pazogwiritsa ntchito zosiyanasiyana.

Poyerekeza ndi mapaipi achikale amawotcherera,S235 J0 chitoliro chachitsulo chozungulira ili ndi mbali zotsatirazi:

A. Panthawi yopanga, mbale yachitsulo imapunduka mofanana ndipo imakhala ndi zovuta zochepa zotsalira.Sikuti izi zimangowonjezera moyo wa chitoliro, zimatsimikiziranso kuti chitolirocho chimakhala chosalala komanso chopanda zingwe kapena zolakwika.

b.Njira yathu yowotcherera ya arc yokhala ndi mbali ziwiri yomwe ili pansi pamadzi imathandizira kuwotcherera bwino kwambiri.Izi zimachepetsa kwambiri kupezeka kwa zolakwika monga m'mphepete molakwika, kupatuka kwa kuwotcherera, komanso kuwotcherera kosakwanira.Chotsatira chake, mipope yathu ili ndi khalidwe labwino kwambiri la kuwotcherera, ndi losavuta kulamulira ndikuonetsetsa kuti ntchito yabwino kwambiri.

C. Ubwino ndiye chinthu chofunikira kwambiri.Choncho, timayendera bwino 100% pazitsulo zilizonse zomwe timapanga.Kuwunika kokwanira kumeneku kumatsimikizira kuti mapaipi athu amakwaniritsa miyezo yapamwamba kwambiri yamakampani, kukupatsani mtendere wamumtima nthawi yonse yopanga ndikugwiritsa ntchito.

Ku Cangzhou Spiral Steel Pipe Group Co., Ltd., timanyadira kwambiri kupangaS235 J0 Spiral Chitoliro chachitsulo.Tili mumzinda wa Cangzhou, m'chigawo cha Hebei ndipo takhala tikugwira ntchitoyi kuyambira 1993. Kuphimba dera la 350,000 lalikulu mamita ndi chuma chonse cha yuan 680 miliyoni, kwayala maziko olimba a luso lopanga.Gulu lathu lodzipatulira la antchito aluso 680 limagwira ntchito molimbika kuti awonetsetse kupanga kosasinthika komanso kutumiza munthawi yake matani 400,000 a mapaipi achitsulo ozungulira pachaka.
