Pane nzira nhatu huru dzekuziva mapaipi akasungwa uye mapaipi asina musono (smls):

1. Metallographic nzira

Metallographic nzira ndiyo imwe yenzira huru dzekusiyanisa mapaipi akasungwa uye mapaipi asina musono. High-frequency resistance welded pombi (ERW) haiwedzeri zvinhu zvekugezesa, saka weld seam mu welded steel pombi yakamanikana, uye weld seam haigone kuoneka zvakajeka kana nzira yekugaya nekuora ikashandiswa. Kana iyo yakakwira-frequency kuramba yakakwenenzverwa simbi pombi yakasungwa pasina kupisa kwekupisa, chimiro che weld seam chinozove chakasiyana kubva kune mubereki zvinhu zvepombi yesimbi. Panguva ino, iyo metallographic nzira inogona kushandiswa kusiyanisa welded simbi pombi kubva musono simbi pombi. Muchiito chekuziva mapaipi maviri esimbi, zvakakosha kucheka sampuli diki ine kureba uye hupamhi hwemamirimita makumi mana panzvimbo yewelding, kuita kugaya kwakakasharara, kugaya kwakanaka uye kupukuta pairi, uye wozoona chimiro pasi pe metallographic. maikorosikopu. Welded simbi pombi uye seamless simbi pombi anogona kunyatsosiyaniswa kana ferrite uye widmansite, base simbi uye weld zone microstructures inocherechedzwa.

2. Corrosion nzira

Mukuita kwekushandisa nzira yekuora kuona mapombi akasungwa uye mapaipi asina musono, musono wakashongedzerwa wepombi yesimbi yakakwenenzverwa inofanira kukwenenzverwa. Mushure mokunge kukuya kwapera, zviratidzo zvekukuya zvinofanira kuonekwa, uye ipapo chiso chekupedzisira chemushonga welded inofanira kusvibiswa nejecha. Uye shandisa 5% nitric acid doro mhinduro yekurapa magumo kumeso. Kana pane weld yakajeka, inogona kuratidza kuti pombi yesimbi ipipi yesimbi yakashongedzwa. Zvisinei, kuguma kwechiso chepombi yesimbi isina musono haine misiyano iri pachena mushure mekunge yasvibiswa.

Zvivakwa zve welded pipe
Welded simbi pombi ine zvinotevera zvivakwa nekuda kwepamusoro-frequency welding, kutonhora kukunguruka uye mamwe maitiro.
Kutanga, basa rekuchengetedza kupisa rakanaka. Kupisa kwekupisa kwe welded simbi mapaipi ishoma, 25% chete, iyo isingangobatsiri kutakura, asiwo inoderedza mari.
Chechipiri, ine kusapinda kwemvura uye nekuora. Mukuita kwekuvaka engineering, hazvidiwi kumisa mapaipi epombi zvakasiyana.
Inogona kuvigwa zvakananga muvhu kana pasi pemvura, nokudaro kuderedza kuoma kwekuvaka kweprojekti.
Chechitatu, ine simba rekudzivirira. Kunyangwe munzvimbo yakadzika yekushisa, pombi yesimbi haingakuvadzi, saka kushanda kwayo kune zvimwe zvakanakira.

Zvivakwa zvepaipi isina musono
Nekuda kwekusimba kwakasimba kwesimbi yepombi yesimbi isina musono, kugona kwayo kuramba kukuvadzwa kwakasimba, uye ine mugero usina mhango, saka inokwanisa kunyatso kutakura mvura. Simbi pombi, uye kuoma kwayo kwakakura. Naizvozvo, iyo yakawanda mutoro iyo isina musono simbi pombi inogona kutakura, inogona kushandiswa zvakanyanya mumapurojekiti ane yakakwirira kuvaka zvinodiwa.

3. Kusiyanisa maererano nemaitiro

Mukuita kwekuona mapombi akasunganidzwa uye mapaipi asina musono zvinoenderana nemaitiro, mapombi esimbi akaiswa welded zvinoenderana nekutonhora kukunguruka, extrusion uye mamwe maitiro. Kana pombi yesimbi yaiswa welded, ichaita spiral welded pombi uye yakatwasuka seam welded pombi, uye ichaita pombi yesimbi yakatenderera, sikweya yesimbi pombi, oval simbi pombi, peipi yesimbi ine mativi matatu, pombi yesimbi ine hexagonal, a rhombus simbi pombi, octagonal simbi pombi, uye kunyange yakaoma simbi pombi.

Muchidimbu, maitiro akasiyana anozogadzira mapaipi esimbi emhando dzakasiyana, kuitira kuti mapaipi esimbi akasungwa uye mapaipi esimbi asina musono anogona kunyatsosiyaniswa. Nekudaro, mukuita kuona mapombi esimbi asina musono zvinoenderana nemaitiro acho, anonyanya kuenderana nekupisa kukungurutsa uye kutonhora kukungurutsa nzira dzekurapa. Kune kunyanya marudzi maviri epombi dzesimbi dzisina musono, dzakakamurwa kuita pombi dzesimbi dzisina musono dzinopisa uye pombi dzesimbi dzisina musono dzinotonhora. Mapaipi esimbi anopisa akakungurutswa akaitwa nekuboora, kukunguruka uye mamwe maitiro, kunyanya mahombe-dhayamita uye makobvu esimbi asina musono pombi anosungwa nekuita uku; mapaipi anotonhorera anoumbwa neinotonhora-inodhirowa chubhu mabhesi, uye simba rechinhu chakaderera, asi kunze kwayo uye mukati mekutonga kwemukati kwakatsetseka.

4. Rongedza nekushandisa

Mapombi esimbi akakwenenzverwa ane yakakwirira kubhenda uye torsional simba uye yakawanda-yekutakura mitoro, saka anowanzo shandiswa zvakanyanya mukugadzira zvikamu zvemakanika. Semuenzaniso, mapaipi ekubooresa oiri, maburi emotokari, mafuremu emabhasikoro, uye chikafori chesimbi chinoshandiswa pakuvaka chivako zvese zvinogadzirwa nemapombi esimbi akakandwa. Zvisinei, pombi dzesimbi dzisina musono dzinogona kushandiswa sepombi dzekufambisa mvura nekuti dzine mativi asina mhango uye tambo refu dzesimbi dzisina musono padzinenge dzakatenderedzwa. Semuenzaniso, inogona kushandiswa sepombi yekutakura oiri, gasi rechisikigo, gasi, mvura, etc. Mukuwedzera, simba rekukotama resimbi isina musono pombi idiki, saka rinowanzo shandiswa zvakanyanya mumapombi anopisa anopisa epasi uye. zvepakati pressure boilers, mapombi emvura ari kufashaira uye mapombi anopisa anopisa emagetsi anopisa. Muchidimbu, kuburikidza nechikamu chekushandiswa, tinokwanisa kusiyanisa zvakajeka mapaipi esimbi akasungwa uye mapaipi esimbi asina musono.
