Spiral simbi pombi tkutonga kwe emperature

Spiral simbi pombi welding tembiricha inonyanya kukanganiswa ne-high-frequency eddy thermal power, high-frequency eddy ikozvino kupisa simba rinonyanya kukanganiswa nehuwandu, simba uye thermal eddy ikozvino excitation frequency inofananidzwa nekona;asiwo neazvino excitation frequency excitation voltage, yazvino uye capacitance, inductance.

Kana kushayikwa kwekupisa kwekupisa, iyo weld edge inopisa kusvika kune tembiricha isingasviki welding, chimiro chesimbi chinoramba chakasimba, kuumbwa kwekusakwana fusion kana kupinda mukati;kusakwana kana apinda kupisa, weld mupendero pamusoro kudziyisa soldering tembiricha, zvichiguma nokupiswa kana droplet, kuti weld kuumbwa Mapako.

Welding multilayer ye spiral welded simbi pombi zvakare inotarisa inter-layer tembiricha kudzora kutonhora chiyero padhuze ne weld zone.Interface tembiricha uye preheat tembiricha zvinowanzofanana.Pasi pekudzivirira kupisa kwenzvimbo padhuze neseam zone pakati peyepamusoro layer inodzivirira kutonhora kwekutsemuka panguva yemulti-pass welding.Mushure kupisa kurapwa uye welding kupisa pombi kuvakwa hakuwanzoitwa mushure mekupisa kurapwa mushure mekunama uye kupisa kurapwa.Asi pakuvaka munharaunda yealpine, kana iyo inter-preheat uye interface tembiricha kutonga kwakaoma kuita basa rakakura, zvinodikanwa kutora mamwe majoini mushure mekupisa kupisa uye kupisa kurapa matanho.

Spiral simbi pombi yekuisa maitiro

Spiral pombi mukushanda kune saiti, kutanga maererano nemidziyo uye fittings chinzvimbo chekupedza pombi, uye mumunda uchave wakananga hurefu hwepombi imwe neimwe yekuyera yakanaka, nyora saizi chaiyo uye chinzvimbo chegadziriro kuitira kufambisa kushorwa, pasi kushandiswa kwechubhu yecrane, chubhu yepasi panguva yekusimudza naironi chipfuramabwe kuchengetedza kuvharirwa kwepombi.

1:kugadzirisa muromo

Kugadzirisa zviteshi zvakanyura mufekitori pombi kugadziridzwa kunopedzwa, kuitira kuve nechokwadi chemhando yewelding, welding isati yaongororwa zvizere, kugadzirisa, kugadzira pombi kupera, bevel angle, blunt edge, kutenderera, nezvimwe, zvinoenderana nevamwe vavo. mune zvinodiwa saizi yemajoini, kudiwa kwepombi yega yega inoitwa mumunda webeveling process, kushandiswa kwegasi welding yekucheka, bvisa slag uye wozoshandisa vhiri rakakwenenzverwa rakatsetseka.

Maitiro ekushanda: Tarisa iyo interface yekubatanidza saizi→bhurugwa rakajeka→sarudza uye gadzirisa nzvimbo yesimbi pombi longitudinal welds akadzedzereka→yekutanga conduit inotarisa yakatwasuka vamwe vanogadzirisa gap dimension→pipeline tambo dzakaenzanirana dzichiita sedzakatwasuka→nzvimbo welding

2: Welding

Interface welding uchishandisa arc welding, zvakare kutsigira, yakapona kaviri, uye pese painopera musono welding, imwe neimwe arc welding point inotungamira kuti idzedzereke.Gadzirisa welding pombi majoini anofanira kutangirwa nemuromo, slag, bevel angle pombi kupera kumeso, blunt mupendero, gaka rinofanira kuenderana nekutsanangurwa;clip haigone kubatsira strip welding kana kudziyisa vamwe gap kuderedza gap welding.Mapiritsi anofanirwa kunge achipeperetswa nemadziro emukati, aine akareba 300mm mutongi kuitira kutenderedza madziro emukati achivhara interface, iyo isiriyo port inobvumira chikamu cheki chinofanira kunge chiri 0.2 nguva mutsauko pakati pekukora kwemadziro, uye isingapfuuri 2mm.
