S235 J0 Spiral Simbi Pipe - Kuita Kwakanakisa KweDimita Yakakura Yakasungwa Pipe
Isu tinodada kuunza yedu yepamusoro-ye-iyo-mutsara chigadzirwa,S235 J0 Spiral Steel Pipe, yakagadzirirwa kusangana nezvinodiwa zvinokura zvemaindasitiri akasiyana.Semugadziri anotungamira mumunda, tinoshandisa tekinoroji yepamusoro uye hunyanzvi kugadzira zvemhando yepamusoromutsara pombi nekusimba kwakasarudzika uye kuita.
Yedu spiral simbi mapaipi anogadzirwa kubva strip simbi coils kuburikidza otomatiki mbiri-waya mbiri-mativi akanyudzwa arc welding process.Kuburikidza neanogara tembiricha extrusion molding tekinoroji, isu tinova nechokwadi chekuti chubhu yega yega inogadzirwa nehupamhi hwepamusoro uye kuenderana.Iyi inyanzvi yekugadzira maitiro inovimbisa kuti zvigadzirwa zvedu zvinosangana nemhando yepamusoro miyero, zvichiita kuti ive yakakodzera kune akasiyana maapplication.

Yedu spiral simbi mapaipi anogadzirwa kubva strip simbi coils kuburikidza otomatiki mbiri-waya mbiri-mativi akanyudzwa arc welding process.Kuburikidza neanogara tembiricha extrusion molding tekinoroji, isu tinova nechokwadi chekuti chubhu yega yega inogadzirwa nehupamhi hwepamusoro uye kuenderana.Iyi inyanzvi yekugadzira maitiro inovimbisa kuti zvigadzirwa zvedu zvinosangana nemhando yepamusoro miyero, zvichiita kuti ive yakakodzera kune akasiyana maapplication.
Kuenzaniswa nemapombi echinyakare akasungwa,S235 J0 spiral simbi pombi ine zvinotevera zvakakosha zvinhu:
A. Panguva yekugadzira, ndiro yesimbi inoshandura zvakaenzana uye ine zvishoma zvakasara zvinonetsa.Izvi hazvisi izvo chete zvinowedzera hupenyu hwepombi, zvakare inovimbisa kuti iyo pombi yepamusoro inotsvedza uye isina mavanga kana kukanganisa.
b.Yedu yepamberi mbiri-mativi yakanyura arc welding process inogonesa chaiyo welding munzvimbo yakanaka.Izvi zvinoderedza zvakanyanya kuitika kwehurema senge misaligned edges, welding deviations, uye isina kukwana welding.Nekuda kweizvozvo, mapaipi edu ane yakanakisa welding mhando, ari nyore kudzora uye chengetedza kuita kwakanakisa.
C. Hunhu ndiyo inonyanya kukosha kwatiri.Nokudaro, tinoita zvakakwana 100% yehutano hwekuongorora pane imwe neimwe pombi yesimbi yatinogadzira.Kuongorora kwakazara uku kunovimbisa kuti mapaipi edu anosangana neakanyanya indasitiri zviyero, achikupa rugare rwepfungwa mukati mekugadzira uye kushandisa maitiro.
PaCangzhou Spiral Steel Pipe Group Co., Ltd., tinodada nekugadziraS235 J0 Spiral Steel Pipe.Isu tiri muCangzhou City, Hebei Province uye tanga tichishandira indasitiri iyi kubvira 1993. Kuvhara nzvimbo inosvika 350,000 square metres uye hupfumi hwese hwe680 miriyoni yuan, yakateya nheyo yakasimba yekugona kugadzira.Chikwata chedu chakazvitsaurira chevashandi vane hunyanzvi makumi matanhatu vanoshanda nesimba kuti vaone kugadzirwa kusina musono uye nekuuya nenguva kwe400,000 matani emapombi esimbi espiral pagore.
