Zvido zvehunyanzvi zvemapombi akatwasuka seam welded: Izvo zvehunyanzvi zvinodikanwa uye kuongororwa kwemapombi akatwasuka seam welded akavakirwa paGB3092 "Welded Simbi Mapaipi eLow-Pressure Fluid Transport" chiyero. Iyo yezita dhayamita yepombi yakashongedzwa ndeye 6 ~ 150mm, iyo yezita remadziro ukobvu ndeye 2.0 ~ 6.0mm, uye kureba kwepombi yakashongedzwa Kazhinji 4 ~ 10 metres, inogona kutumirwa kubva kufekitori muhurefu hwakatarwa kana kureba kwakawanda. Pamusoro pepombi yesimbi inofanira kunge yakatsetseka, uye kukanganisa kwakadai sekupeta, kuputika, delamination, uye lap welding hazvibvumirwi. Pamusoro pepombi yesimbi inobvumirwa kuve nezvikanganiso zvidiki senge scratches, scratches, weld dislocations, kutsva, uye mavanga asingapfuure kutsauka kwakashata kwemadziro emadziro. Iko kukora kwemadziro emadziro pane weld uye kuvapo kwemukati weld bars kunobvumidzwa. Mapombi esimbi akasungwa anofanirwa kuita bvunzo dzekuita zvemakanika, bvunzo dzekubata kumeso, uye bvunzo dzekuwedzera, uye dzinofanirwa kusangana nezvinodiwa zvakatemwa muyero. Iyo pombi yesimbi inofanirwa kukwanisa kumira mukati meiyo 2.5Mpa uye chengetedza pasina kuvuza kweminiti imwe. Inotenderwa kushandisa iyo eddy yazvino kukanganisa kukanganisa nzira panzvimbo yeiyo hydrostatic bvunzo. Eddy ikozvino kuona kukanganisa kunoitwa neyakajairwa GB7735 "Eddy Current Flaw Detection Inspection Method yeSimbi Pipes". Iyo eddy yezvino kukanganisa kukanganisa nzira ndeyekugadzirisa probe pafuremu, chengeta chinhambwe che 3 ~ 5mm pakati pekuona kukanganisa uye weld, uye kuvimba nekukurumidza kufamba kwepombi yesimbi kuti iite yakazara scan ye weld. Iyo chiratidzo chekukanganisa inogadziriswa otomatiki uye inorongwa otomatiki neiyo eddy yazvino flaw detector. Kuzadzisa chinangwa chekuona kukanganisa. Mushure mekuona kukanganisa, pombi yakasungwa inochekwa kusvika paurefu hwakatarwa nesaha inobhururuka uye inokungurutswa kubva pamutsetse wekugadzira kuburikidza neflip furemu. Migumo miviri yepombi yesimbi inofanira kunge yakaita flat-chamfered uye yakanyorwa, uye pombi dzakapedzwa dzinofanira kurongedzerwa mumasumbu ane hexagonal dzisati dzabuda mufekitari.

Yakatwasuka simbi yesimbi pombi yekugadzira nzira: Yakatwasuka musono simbi pombi ipombi yesimbi ine weld musono inofambirana nekureba kwenzira yepombi yesimbi. Kusimba kwepombi yesimbi kunowanzo kukwirira kupfuura kweiyo straight seam welded pombi. Inogona kushandisa mabheti akamanikana kugadzira mapaipi makuru-diameter welded, uye anogonawo kushandisa mabheti ehupamhi hwakafanana kugadzira pombi madhayamita. Mapombi akasiyana-siyana. Zvisinei, kana zvichienzaniswa nemapaipi akatwasuka ehurefu hwakafanana, kureba kweweld kunowedzerwa ne30 ~ 100%, uye kukurumidza kwekugadzira kwakaderera. Saka ndedzipi nzira dzayo dzekugadzirisa?

1. Kugadzira simbi: Kumanikidza kugadzirisa nzira inoshandisa kudzoreredzwa kwesando yefodya kana kudzvanywa kwemuchina kushandura isina chinhu muchimiro uye saizi yatinoda.
2. Extrusion: Iyo isimbi yekugadzira nzira iyo simbi inoiswa muvhavha yakavharwa cylinder uye kumanikidzwa kunoshandiswa kune rumwe rutivi kuti ibudise simbi kubva kune yakatemerwa gomba rekufa kuti uwane chigadzirwa chakapedzwa chechimiro chakafanana uye ukuru. Inonyanya kushandiswa pakugadzirwa kwesimbi isina-ferrous. Material simbi.
3. Kutenderedza: Kudzvinyirira nzira yekugadzira iyo iyo simbi isina chinhu inopfuura nepaburi (yemhando dzakasiyana-siyana) pakati peviri inotenderera inotenderera. Pamusana pekumanikidzwa kwema rollers, chikamu chezvinyorwa chinoderedzwa uye urefu hunowedzera.
4. Simbi yekudhirowa: Inzira yekugadzira inokwevera simbi yakavharwa isina chinhu (yakaumbwa, chubhu, chigadzirwa, nezvimwewo) kuburikidza negomba rekufa kuderedza chikamu chemuchinjikwa uye kuwedzera urefu. Mazhinji acho anoshandiswa kutonhora kugadzirisa.
