Muindasitiri yesimbi, DN300 simbi pombi ndiyo yakajairika hombe-dhayamita simbi pombi. DN300 inoreva dhayamita rezita repombi iri 300 mm, inova yakakura dhayamita yesimbi pombi yakatarwa. Sechinhu chakakosha chekuvaka, pombi yesimbi inoshandiswa zvakanyanya muindasitiri, kuvaka, peturu, indasitiri yemakemikari, uye mamwe minda.

Kutanga, maitiro eDN300 simbi pombi

DN300 simbi pombi ine zvinotevera akakosha maficha:
1. Yakakura dhayamita: Zita rezita reDN300 simbi pombi ndeye 300 mm. Kuenzaniswa nemapombi esimbi madiki-diameter, ine dhayamita yakakura uye inogona kuzadzisa zvinodiwa zvedzimwe nguva dzakakosha.
2. Rusvingo rwakakora: Nekuda kwedhayamita yakakura yeDN300 simbi pombi, ukobvu hwayo hwemadziro hunowedzera zvinoenderana, hunogona kumirisana nekumanikidza kukuru uye mutoro, uye ine simba rakakwirira uye kusimba.
3. Zvakawanda zvinoshanda: DN300 simbi pombi yakakodzera siyana indasitiri minda, akadai petroleum, makemikari indasitiri, kudziyisa, mvura, etc. Mumafuta uye gasi gasi kutakura, DN300 simbi pombi inowanzoshandiswa sezvo huru kutapurirana mapaipi.
4. High corrosion resistance: DN300 simbi mapaipi anowanzobatwa ne-anti-corrosion treatment, iyo inogona kunyatsodzivisa kukanganiswa kwemakemikari zvinhu uye nhepfenyuro inoparadza uye kuwedzera hupenyu hwavo hwebasa.

Chechipiri, kushandiswa kweDN300 simbi pombi

DN300 simbi pombi ine zvakasiyana-siyana zvekushandisa, kunyanya kusanganisira zvinotevera zvinhu:
1. Kutakura mafuta uye gasi rechisikigo: DN300 simbi mapaipi anowanzoshandiswa kutakura mafuta uye gasi rechisikigo uye kuita basa rinokosha rekubatanidza nzvimbo dzakasiyana. Iyo yakakura dhayamita uye yakakwirira simba inoita kuti ive sarudzo yakanaka yekufambisa oiri uye gasi.
2. Mapurojekiti ekuvaka: Mumapurojekiti makuru ekuvaka, akadai semabhiriji, zvivakwa zvepamusoro-soro, nezvimwewo, DN300 mapaipi esimbi anowanzoshandiswa mukutsigira zvivakwa, trusses, makoramu anotakura, nezvimwewo, kuita basa mukudzikamisa. uye rutsigiro.
3. Zvishandiso zveindasitiri: Mapaipi makuru-diameter anodiwa mumidziyo yakawanda yeindasitiri. DN300 simbi mapaipi anogona kusangana nezvinodiwa zvemidziyo iyi yekufambisa midhiya, senge makemikari ekugadzira midziyo, zvekudziisa, nezvimwe.
4. Kurapa kwemvura: DN300 simbi mapaipi anoshandiswawo zvakanyanya mukufambisa kwemvura uye madhiraini masisitimu ekutakura mvura yakachena, tsvina, uye yakacheneswa mvura.

Chechitatu, nzira yekugadzira yeDN300 simbi pombi

Iyo yekugadzira maitiro eDN300 simbi pombi inowanzo sanganisira anotevera matanho:
1. Kugadzirira kwezvinhu: Sarudza simbi yakakodzera seyakagadzirwa, kazhinji kabhoni simbi, alloy simbi, nezvimwe.
2. Kugadzirwa kwepombi isina chinhu: Simbi inochekwa, yopiswa, uye yakaboborwa kuita kuti pombi isina chinhu yehurefu hwakati.
3. Pipe blank rolling: Kuburikidza ne-multi-pass rolling yepombi isina chinhu muchigayo, pombi yesimbi ine dhayamita inodiwa uye ukobvu hwemadziro inoumbwa zvishoma nezvishoma.
4. Kugadzira uye kutwasanudza: Iyo pombi yesimbi yakakungurutswa inotwasanudzwa uye inochekwa kuburikidza nemuchina wekugadzira kuti ive nechitarisiko chakatarwa uye saizi.
5. Welding kurapwa: Weld pombi yesimbi sezvinodiwa kuti uve nechokwadi chekutendeseka uye kubatana kwepombi.
6. Kugadziriswa kwepamusoro: Ita kurapwa kwepamusoro sekubvisa ngura uye anti-corrosion papombi yesimbi kuti ivandudze kusagadzikana kwayo uye kutaridzika kwemhando.
7. Kuongorora uye kurongedza: Ita maitiro akasiyana-siyana ekuongororwa pane yakagadzirwa DN300 simbi mapaipi, akadai sekuongorora ukuru, kuongorora kushanda kwemuviri, nezvimwewo, uye kuvhara uye kuisa mazita kuti zvive nyore kutakura uye kushandiswa.

Kupfupisa, DN300 simbi pombi, seinowanzo shandiswa hombe-dhayamita simbi pombi, zvikuru kushandiswa indasitiri uye kuvaka minda. Zvimiro zvinosanganisira yakakura dhayamita, gobvu madziro, yakafara application, uye yakakwirira corrosion resistance. Kuburikidza nemaitiro akakodzera ekugadzira, DN300 simbi mapaipi ane mhando yepamusoro uye yakanakisa kuita inogona kugadzirwa kuti isangane neakasiyana mainjiniya zvinodiwa. Mukuvandudza mune ramangwana, nekufambira mberi kwesainzi uye tekinoroji uye kuvandudzwa kwehunyanzvi, DN300 simbi pombi ichaita zvirinani kuenderana nezvinodiwa zvemarudzi ese ehupenyu uye kuita mipiro yakakura mukusimudzira nzanga.
