Mapombi esimbi anouya nenzira dzakawanda uye nehukuru. Seamless pombi isarudzo isina-welded, yakagadzirwa nehollowed steel billet. Kana zvasvika kune welded simbi mapaipi, pane zvitatu zvingasarudzwa: ERW, LSAW uye SSAW.
Mapaipi eERW anogadzirwa neresitorendi akaiswa simbi. LSAW pombi inogadzirwa nelongitudinal yakanyura arc welded simbi ndiro. SSAW pombi inogadzirwa ne spiral yakanyura arc welded simbi ndiro.
Ngatitarisei zvakanyanya pamhando yega yega yepombi, enzanisa misiyano yavo, uye nzira yekushandisa tsananguro chaiyo kuronga.
Seamless simbi chubhu
Iyo chubhu isina musono inogadzirwa nesimbi isina simbi billet, iyo inopisa uye ine perforated kuti iite denderedzwa hollow chikamu. Nekuti pombi isina musono haina nzvimbo yewelding, inoonekwa seine simba kupfuura welded pombi uye isingaite ngura, kukukurwa uye kutadza zvachose.
Zvakadaro, mutengo patani imwe yepombi isina musono uri 25-40% yakakwirira kupfuura yeERW pombi. Seamless simbi pombi saizi kubva 1/8 inch kusvika 36 inch.
Resistance welding (RW) pombi
ERW (resistance welding) simbi pombi inoumbwa nekukungurutsa simbi mupombi uye kubatanidza migumo miviri nema electrode maviri emhangura. Aya ma electrodes ane disc-shaped uye anotenderera sezvo zvinhu zvinopfuura pakati pavo. Izvi zvinobvumira electrode kuchengetedza kuenderera mberi nekubatana nezvinhu kwenguva yakareba yekuenderera mberi welding. Kufambira mberi kwehunyanzvi hwekugadzira welding inoenderera mberi nekuvandudza maitiro aya.
ERW pombi inzvimbo ine hupfumi uye inoshanda yekutsiva simbi isina musono pombi, iyo yakasimba kupfuura SAW pombi. Kana ichienzaniswa neyekunyungudutsa inoshandiswa mumvura yakanyungudutswa arc welded pombi, zvirema zvakare hazvigone kuitika, uye iyo yakatwasuka weld defects inogona kuonekwa nyore nyore ne ultrasonic reflection kana kuona.
Iyo dhayamita yeERW pombi inotangira kubva pamasendimita (15 mm) kusvika 24 inches (21.34 mm).
Yakadzika arc welded pombi
LSAW (yakatwasuka musono welding) uye SSAW (spiral seam welding) zvakasiyana-siyana zvepaipi yakanyudzwa arc welded. Iyo yakadzika arc welding process inoburitsa yakakwira ikozvino density kudzivirira kukurumidza kupisa kupera kweiyo flux layer uye kuisa pfungwa munzvimbo yewelding.
Musiyano mukuru pakati peLSAW neSSAW pombi ndiyo inotungamira weld, iyo inozokanganisa kudzvanywa kwekutakura simba uye kureruka kwekugadzira. LSAW inoshandiswa kune yepakati-voltage kune yakakwira-voltage application, uye SSAW inoshandiswa kune yakaderera-voltage application. Mapaipi eLSAW anodhura kupfuura mapaipi eSSAW.
Longitudinal yakanyura arc welded pipe
LSAW pombi inogadzirwa nekugadzira inopisa yakakungurutswa coil simbi mold kuita humburumbira uye kubatanidza migumo miviri pamwechete nemutsara welding. Izvi zvinogadzira pombi yakasungwa kwenguva refu. Mapaipi aya anonyanya kushandiswa kufambisira mapombi akareba emafuta, gasi rechisikigo, marasha emvura, mahydrocarbon, nezvimwe.
Kune marudzi maviri emapombi eLSAW: single longitudinal seam uye kaviri seam (DSAW). LSAW simbi pombi inokwikwidza nesimbi isina musono pombi uye 16 kusvika 24 inch ERW simbi pombi. Muindasitiri yemafuta uye gasi rechisikigo, hombe-diameter API 5L LSAW mapaipi anoshandiswa kureba uye kufambisa kwakanaka kwemahydrocarbons.
Iyo dhayamita yepombi yeLAW kazhinji iri pakati pe16 inches uye 60 inches (406 mm uye 1500 mm).
Seamless - zvinoputika zvakasara zvehondo - longitudinal yakanyura arc welding - spiral yakanyura arc welding - pombi - spiral yakanyura arc welding
SSAW pombi
SSAW simbi pombi inoumbwa nekukunguruka uye welding simbi tambo mu spiral kana spiral direction kuita weld kuita spiral. Iyo spiral welding process inoita kuti zvikwanise kugadzira yakakura-dhayamita zvigadzirwa. Spiral simbi mapaipi anonyanya kushandiswa kune yakaderera kudzvinyirira kwemvura kutapurirana, senge mapaipi mumapuratifomu ekumahombekombe, petrochemical zvidyarwa kana nhandare dzengarava, pamwe nezvivakwa zvevagari uye murwi.
Iyo dhayamita yepombi yeSSAW inowanzoita 20 inches kusvika 100 inches (406 mm kusvika 25040 mm).
Maitiro ekuhodha mapaipi esimbi epurojekiti yako
Paunenge uchiraira pombi dzesimbi, pane maviri akakosha zviyero: saizi yepombi yezita (NPS) uye ukobvu hwemadziro (chirongwa). Pamapaipi asingasviki 4 inches, urefu hwepombi hunogona kuve husina kurongeka (SRL) 5-7 metres, kana kune mapaipi anopfuura masendimita mana, kureba kwepombi kunogona kuita kaviri zvisina tsarukano (DRL) 11-13 metres. Hurefu hwetsika huripo kune mapaipi akareba. Migumo yepombi inogona kuve bevel (kuva), ndege (pe), shinda (THD) shinda uye coupling (T&C) kana groove.
