Simba uye Kuvimbika kweMapaipi Ekuvaka Akaita Hollow-Section: Kutarisa Kwakadzama Mapaipi Akanyudzwa Arc Welded Pipe neAPI 5L Line Pipe Mufananidzo Unoratidzwa

Tsananguro pfupi:

Mutemo uyu ndewekupa mwero wekugadzira masisitimu emapaipi ekufambisa mvura, gasi nemafuta mumaindasitiri emafuta negasi rechisikigo.

Kune mazinga maviri ekugadzirwa kwechigadzirwa, PSL 1 nePSL 2, PSL 2 ine zvinodiwa zve carbon equivalent, notch simplicity, maximum goeth strength uye tensile strength.

Giredhi B, X42, X46, X52, X56, X60, X65, X70 uye X80.

Cangzhou Spiral Steel pipes group co.,ltd inopa mapaipi eSAWH ane giredhi kubva kuAPI B kusvika kuX70, takawana chitupa cheAPI 5L makore apfuura uye ikozvino mapaipi edu anoshandiswa zvakanyanya neCNPC, CPECC kumapurojekiti avo emapaipi.

Suma:

Munyika yekuvaka nekuvandudza zvivakwa, kusarudza zvinhu zvakakodzera kwakakosha.Mapaipi ekuvaka ane chikamu chisina chinhu inoita basa rakakosha mukupa simba, kugara kwenguva refu uye kuvimbika kumapurojekiti akasiyana-siyana. Mublog rino, tichaongorora hunhu nemabhenefiti emhando mbiri dzakakosha dzemapaipi ekuvaka: spiral submerged arc welded pipe uye API 5L line pipe.

Pombi yesimbi yakanyudzwa nearc yakasungirirwa:

Pombi yesimbi yakanyudzwa mumvura (SAW), inozivikanwawo sepombi yeSSAW, inoshandiswa mumhando dzakasiyana-siyana dzekushandisa. Chinhu chinoshamisa chePombi yeSSAW ndiyo misono yayo inotenderera, iyo inopa simba rakakura uye kugona kutakura mutoro zvichienzaniswa nedzimwe mhando dzemapaipi. Dhizaini iyi yakasiyana inobatsira kugovera kushushikana zvakaenzana mupaipi yese, zvichiita kuti ive yakakodzera mapurojekiti anoda kusimba kwechimiro.

Kuedzwa kweHydrostatic

tsananguro yechigadzirwa1

Pombi inofanira kumira bvunzo ye hydrostatic pasina kubuda nemusono we weld kana muviri wepombi.
Majoini haafanirwe kuongororwa ne hydrostatic, chero bedzi zvikamu zvepaipi zvinoshandiswa pakuisa chiratidzo pajoini zvakaedzwa ne hydrostatic zvisati zvaitika.

Kutevedzana:
Pamuchina wePSL 1, mugadziri anofanira kutanga nekutevera nzira dzakanyorwa dzekuchengetedza:
Kuzivikanwa kwekupisa kusvika bvunzo dzese dze chmical dzaitwa uye kutevedzera zvinodiwa zvakatarwa kwaratidzwa.
Kuzivikanwa kweyuniti yekuedza kusvika bvunzo dzese dzemakanika dzaitwa uye kutevedzera zvinodiwa zvakatarwa kwaratidzwa.
Pamuchina wePSL 2, mugadziri anofanira kugadzira nekutevera nzira dzakanyorwa dzekuchengetedza hunhu hwekupisa uye hunhu hwechiyedzo chemuchina wepombi yakadaro. Nzira dzakadaro dzinopa nzira dzekutevera hurefu hwepombi kusvika kuyuniti chaiyo yekuyedza uye mhedzisiro yekuyedza kwemakemikari yakabatana.

Chimwe chezvakanakira zvikuru zvepombi yeSSAW ndiko kuchinjika kwayo pakugadzira. Mapombi aya anogona kugadzirwa muhukuru hwakasiyana-siyana, dhayamita uye ukobvu uye anogona kugadziriswa kuti aenderane nezvinodiwa zvepurojekiti chaiyo. Pamusoro pezvo, mapombi akasungirirwa esimbi akadzika midzi anowanzo gadzirwa nesimbi yepamusoro-soro, zvichiita kuti asapararire ngura uye ave nechokwadi chekuti anogara kwenguva refu.

API 5L Line Pipe:

API 5L mutsetse wepombiipombi yekuvaka ine chikamu chisina chinhu inoshandiswa zvakanyanya inosangana nezvinodiwa neAmerican Petroleum Institute (API). Mapaipi aya akagadzirirwa kutakura mvura, senge mafuta negasi rechisikigo, mudaro refu. Pombi yemutsara yeAPI 5L inozivikanwa nekusimba kwayo kwakanyanya, kugara kwenguva refu uye kuramba mamiriro ekunze akaipisisa.

Maitiro ekugadzira mapaipi emuchina weAPI 5L anosanganisira matanho akasimba ekudzora mhando kuti ive nechokwadi chekuti akavimbika. Mapaipi aya akagadzirwa nesimbi yekabhoni uye ane hunhu hwakanaka hwemakanika. Kutevedzera zvakanyanya mitemo yeAPI kunoita kuti mapaipi aya agone kumira kumanikidzwa kwakanyanya uye kuchinja kwekushisa, zvichiita kuti akwanise kushandiswa zvakanyanya muindasitiri yemafuta negesi.

Zvakanakira zvakabatanidzwa:

Kana pombi yakasungirirwa yesimbi yakanyudzwa mumvura ine arc uye pombi yemutsara yeAPI 5L zvikabatanidzwa, zvinopa hunhu hwakanaka uye kuvimbika kusingaenzaniswi. Misono yesimbi yepombi yeSSAW pamwe chete nesimba uye kugara kwenguva refu kwepombi yemutsara yeAPI 5L zvinogadzira sisitimu yakasimba yekutsigira chimiro.

Kuwedzera kune zvakanakira zvadzo, kuenderana kwepombi dzakasungirirwa dzakaita sespiral immersed arc uye pombi yemutsara yeAPI 5L kunowedzera kushanda zvakanaka kwemapurojekiti epombi. Kuchinja-chinja kwepombi yeSSAW kunoita kuti zvive nyore kubatanidza nepombi yemutsara yeAPI 5L, zvichiita kuti mvura ifambe zvakanaka mukati me network yepombi.

Mukupedzisa:

Mapaipi ekuvaka ane mativi asina chinhu akakosha zvikuru pakuvaka zvivakwa zvakasimba. Kushandiswa pamwe chete kwepombi dzeSSAW nepipi dzemutsara dzeAPI 5L kunopa mhinduro ine simba inopa simba, kugara kwenguva refu uye kuvimbika kumapurojekiti akasiyana-siyana. Ingave kutsigira nheyo dzezvivakwa zvirefu kana kutakura mvura yakakosha munzvimbo refu, mapaipi aya anoita basa rakakosha mukuona kuti zvivakwa zvedu zvinogara kwenguva refu uye kugadzikana. Nekushandisa simba repipi dzakasungirirwa dzakaita sespiral submerged arc uye kuvimbika kwepipi dzemutsara dzeAPI 5L, mainjiniya vanogona kuvaka hwaro hwakasimba hweramangwana riri nani.
