Nhanganyaya yeShandong Kungang Spiral Pipe
Pombi inotenderera inogadzirwa nekukungurutsa simbi yakaderera-kabhoni kabhoni kana yakaderera-alloy structural simbi mutsetse muchubhu isina chinhu zvinoenderana neimwe helical angle (inonzi fomu yekona), uyezve welding seam sepombi. Inogona kugadzirwa neyakamanikana strip Simbi inoburitsa hombe dhayamita simbi mapaipi. Zvinotsanangurwa zvaro zvinoratidzwa nekunze dhayamita * madziro ukobvu. Iyo welded pombi inofanirwa kuve nechokwadi chekuti iyo hydraulic bvunzo, kusimba kwesimba re weld uye kutonhora kwekukotama kuita kunofanirwa kusangana nemirairo.
Panyaya yewelding process, nzira yewelding ye spiral welded pombi uye yakatwasuka musono seam simbi pombi yakafanana, asi iyo yakatwasuka musono welded pombi ichava neakawanda maT-shaped welds, saka mukana wehurema hwekushongedza unowedzerawo zvakanyanya. uye kusungirirwa kwakasara paT-shaped welds Kushungurudzika kwakakura, uye weld metal inowanzoita katatu-dimensional stress state, iyo inowedzera mukana wekutsemuka. Uyezve, maererano nemirairo yehunyanzvi yekunyudzwa kwearc welding, weld yega yega inofanirwa kunge iine arc yekutangira uye arc yekudzimisa pombi, asi imwe neimwe yakatwasuka seam welded pombi haigone kusangana nemamiriro ezvinhu aya kana welding denderedzwa seam, saka panogona kunge paine More welding defects.
use
Spiral pombi dzinonyanya kushandiswa muinjiniya yekugovera mvura, indasitiri yepetrochemical, indasitiri yemakemikari, indasitiri yemagetsi emagetsi, kudiridza kwekurima, uye kuvaka maguta. Icho chimwe chemakumi maviri ezvigadzirwa zvakakosha zvakagadziriswa nenyika yedu. Yekufambisa kwemvura: kugovera mvura, dhizaini, injiniya yekurapa tsvina, kutakura madhaka, kufambisa kwemvura yegungwa. Zvekutakura gasi: gasi, chiutsi, liquefied petroleum gasi. Nekuda kwezvinangwa: semapombi ekuputira nemabhiriji; pombi dzema wharves, migwagwa, zvivakwa zvekuvaka, marine piling pombi, nezvimwe.
Product Standards
Spiral musono wakanyura arc welded simbi pombi SY5036-83 for pressuredized fluid transportation inonyanya kushandiswa kuoiri uye gasi chaiwo mapaipi; spiral seam yakakwirira frequency welded simbi pombi SY5038-83 yekumanikidza fluid yekufambisa inoiswa welded nepamusoro frequency lap welding. Spiral seam yakakwira-frequency welded simbi mapaipi ekumanikidzwa kwemvura yekufambisa. Iyo pombi yesimbi ine simba rakasimba rinotakura simba, plastiki yakanaka, uye yakanakira welding nekugadzirisa; iyo spiral seam yakanyura arc welded simbi pombi SY5037-83 kune yakajairika-yakadzika-kudzvanywa kwemvura yekufambisa inogadzirwa nekaviri-mativi otomatiki yakanyudzwa arc welding kana imwe-sided welding yemvura, gasi, Akanyura arc welded simbi pombi dzekufambisa mvura yakaderera-yakaderera. zvakadai semhepo nemhepo.
Zviyero zvinowanzo shandiswa zvespiral simbi mapaipi anowanzo kupatsanurwa kuita: SY/T5037-2000 (ministry chiyero, inozivikanwawo se spiral seam yakanyura arc welded simbi mapaipi emapaipi ekufambisa emvura akajairwa), GB/T9711.1-1997 (yenyika chiyero, zvakare inozivikanwa semafuta uye gasi indasitiri yekufambisa simbi mapaipi) Chikamu chekutanga chekutakura tekinoroji mamiriro: A-giredhi simbi pombi (GB/T9711.2 B-giredhi simbi pombi ine zvinodiwa zvakasimba), API-5L (American Petroleum Institute, inonziwo pipeline pombi yesimbi; iyo yakakamurwa kuita nhanho mbiri: PSL1 uye PSL2), SY/T5040-92 (spiral yakanyura arc welded simbi pombi kuti mirwi).
