Kuvimbika Kwekuvimbika Kwekuvimbika: Spiral Wacheed Carbon Steel pombi muSimbi Pipe Welding maitiro
Suma
Hunyanzvi hweMetal Pipe Waldinginoda musanganiswa unowirirana neunyanzvi, kunyatsojeka uye zvigadzirwa zvemhando yepamusoro kuti uve nechokwadi chekuvimbika kune dzakasiyana siyana dzekushandisa. Pakati pemhando dzakawanda dze pombi, spiral welded carbon jira pombi, senge x42 ssaw pombi, inozivikanwa nesimba rayo rakakwirira, kusimba uye mutengo-wekubudirira. Mune ino blog, isu tichaongorora kukosha kweclorally welded carbon masimbi pombi mulating yelding maitiro, kunyengedza kuita kwayo yekugadzira, zvakanakira uye nzvimbo dzekushandisa.

Kugadzira maitiro
Spiral welded pombi, anozivikanwa seSsaw (Spiral yakakundwa Arc Weld) Pipe, yakagadzirwa uchishandisa Spiral Kugadzira uye yakazotumbuka Arc Welding maitiro. Maitiro acho anotanga nekurapa kurapwa kweiyo yakagadzirwa simbi strip uye inokotama iyo strip mune yekupfira chimiro. Otomatiki yakanyorwa Arc Welding inobva yashandiswa kujoina mipheti yematanho pamwe, zvichigadzira inoenderera mberi nehurefu hwekureba kwepombi. Iyi nzira inovimbisa kuti kubatana kwakasimba uye kusimba nguva kuderedza kuremara uye kuchengetedza kutendeka kwemamiriro ezvinhu.
Zvakanakira zveSpiral Weld Carbon Steel pombi
1. Simba uye kusimba:Spiral Wacheld Carbon Steel pombiinozivikanwa nesimba rayo repamusoro uye kusimba, zvichiita kuti zviite kuti zvibodzwa zvinoda kurwisa kudzvinyirira kudzvinyirira uye kuita kwenguva refu.

1. Mafuta neyechisikigo gasi yegasi Simba ravo uye kugona kwavo kudzivisa nzvimbo dzakakwirira-dzvinyiriro dzinovaita kuti vave vakarasikirwa-kureba.
2. Kutapurirana kwemvura: kungave kwezvinhu zvemvura zvemvura.
3. Rutsigiro rwakatarwa: Iyi mhando yeiyo pombi inoshandiswa zvakanyanya mune yekuvaka indasitiri yekupa rutsigiro rwezvivakwa, mabhiriji, mapurogiramu emamwe mishonga. Kugara kwavo uye kuramba kune zvekunze zvinhu kunovaita vakavimbika pakushandisa kwakadaro.

Mumhedziso
Spiral welded carbon simbi pombi, sengeX42 SSAW PIPE. Simba ravo, kusimba, zvinodhura-zvinobata uye kurongeka kwakazara kunoita kuti kuve takaperera kutendeka mune dzakasiyana siyana dzekushandisa. Iko kugona kwekuramba kwakanyanyisa kudzvinyirira, tembiricha uye nzvimbo dzakashatisa kunoita kuti iite mafuta uye gasi kutapurirana, kuwanikwa kwemvura uye mamwe maindasitiri ezvemaindasitiri. Naizvozvo, kana zvasvika pombi yemasimbi yelding, kushandiswa kweiyo spiral weldaed carbon zvibayiro zvinoramba zviripo uye inoshanda yekugadzirisa kwenguva refu uye kusingaperi uye kusimba kwekugara.
Hydrostatic test
Kureba kwepepe kuchaidzwa nemugadziri kune hydrostatic kumanikidza kuchagadzira madziro kushushikana kwekushaiwa makumi matanhatu muzana yeiyo yakasarudzika shuwa simba rekubereka tembiricha. Dzvinyiriro ichatsanangurwa neiyo inotevera equation:
P = 2st / d
Zvinotenderwa kusiyana kwehuremu uye zviyero
Kureba kwega kwega kwepepe kucharemerwa zvakasiyana uye kurema kwayo hakuzopindiri kupfuura gumi muzana pamusoro kana 5.5% pasi pehuremu hwayo uye huremu hwayo uye huremu hwayo pane urefu hwakareba
Iyo yekunze dhisiki haizosiyane kupfuura ± 1% kubva pane yakatarwa zita rekunze kunze kwedhimoni
Kukudza kwemadziro chero nguva hakuzopfuura kusvika pagumi nemaviri% pasi peiyo yakataurwa madziro madziro
