Longitudinal Welded Process uye Advantageous Characteristics
ERW uye LSAW welded simbi mapaipi ndiwo akajairika longitudinal musono welding matekiniki uye anoshandiswa zvakanyanya.
ERW (Electric Resistance Welding)
Application: Inonyanya kushandiswa kugadzirwa kwediki kusvika pakati-diameter, yakaonda madziro, longitudinally welded simbi machubhu.
Hunhu: kunyunguduka kwezvinhu zvinosangana nekupisa nekupisa, kudziyisa uye kudzvanywa kwesimbi mipendero uchishandisa yakakwirira frequency mafungu.
Zvakanakira: Mutengo unoshanda, unokurumidza kugadzira kumhanya, wakakodzera kukwirisa vhoriyamu kugadzirwa.
Kana uchiziva zvakawanda nezveERW, unogona kudzvanya:ERW Round Tube.
LSAW (Longitudinally Submerged Arc Welding)
Application: Inokodzera kugadzirwa kwedhayamita hombe uye gobvu-yakavezwa longitudinal welded simbi pombi, inowanzoshandiswa mu-high-pressure applications semafuta uye gasi mapaipi.
Hunhu: Mushure mekugadzira ndiro yesimbi muchimiro chechubhu, inosungirirwa uchishandisa yakanyura arc welding pane zvese mukati nekunze panguva imwe chete yepombi yesimbi.
Zvakanakira: Inogona kubata zvakakora zvinhu, yakanaka weld mhando, uye yakakwirira simba.
Kana uchiziva zvakawanda nezveERW, unogona kudzvanya:LSAW Pipe Zvinoreva.
Ngatitarisei kuti ERW neLSAW machubhu anogadzirwa sei!
ERW Pipe Production Process
Kugadzirira kwezvinhu: simbi yesimbi yezvinhu zvakakodzera inosarudzwa uye isati yarapwa.
Kuumba: Mutsetse wesimbi wakakotama kuita chubhu chimiro nenzira yekumanikidza roller.
Welding: High-frequency current inopisa mipendero yesimbi yesimbi uye inoumba weld kuburikidza ne press rollers.
Weld Kuchenesa: Kuchenesa chikamu chinobuda cheweld.
Kurapa kwekupisa: Kuvandudza weld seam chimiro uye pombi zvivakwa.
Kutonhodza uye saizi: Cheka kune hurefu hwakatarwa sezvinodiwa mushure mekutonhora.
Inspection: Ita isiri-kuparadza kuyedza uye kuyedzwa kwemakanika zvivakwa, nezvimwe.
LSAW Steel Pipe Production Process
Kugadzirira kwezvinhu: sarudza ndiro yesimbi yezvinhu zvakakodzera uye ita pre-kurapa.
Kuumba: Kugadzira uchishandisa nzira yakakodzera yekugadzira kukotamisa ndiro yesimbi kuita chubhu.Iyo inowanzoshandiswa kuumba maitiro ndeye JCOE.
Welding: Pre-welding inoitwa kugadzirisa chimiro, uye ipapo yakadzika arc welding inoshandiswa kupinza kubva mukati nekunze panguva imwe chete.
Kururamisa: Kururamisa kunoitwa nemuchina wekururamisa
Kurapa kwekupisa: Normalizing kana stress relieving inoitwa pane welded steel chubhu.
Kuwedzera: Kuvandudza kurongeka kwepimbi yesimbi uye kuderedza kushushikana kwemagetsi.
Inspection: Ita bvunzo senge hydraulic pressure test yekuona chikanganiso uye michina zvivakwa.

Interim Protection
Kune mapaipi esimbi ayo achachengetwa kunze kana kutumirwa negungwa, matanho ekudzivirira kwenguva pfupi anowanzo kutorwa kudzivirira kukanganisa kusati kwaiswa kana kuenderera mberi.
Varnish kana Black Paint: Kuisa jasi revarnish kana pendi dema kunopa dziviriro yenguva pfupi kubva kune ngura, kunyanya munzvimbo dzakanyorova kana dzemunyu.Iyo inzira yehupfumi yekudzivirira kwechinguva iyo iri nyore kushandisa uye kubvisa.
Kuputira: Yakaputirwa mutende, inodzivirira zvinobudirira kukora kunokonzerwa nemamiriro ekunze, kunyanya panguva yekufambisa kwenguva refu kana mamiriro ekunze akaoma.
Anti-corrosion
Iyo anti-corrosion layer inopa kuchengetedzwa kwenguva refu kwepombi yesimbi, kuwedzera hupenyu hwayo hwebasa uye kuve nechokwadi chekugara kwayo uye kushanda munzvimbo dzakasiyana siyana.
Galvanizing: Kupfekedza chigadziko chezinc pamusoro pepombi yesimbi kudzivirira kuparara, zinc layer inogona kubayirwa kuchengetedzwa kweanode pasi pesimbi.
Epoxy Coating: Inowanzoshandiswa pakudzivirira kwekudzivirira kwemukati nekunze kwekunze kwepombi dzesimbi.Inogona kudzivirira mvura neokisijeni kuti isasangana nepamusoro pesimbi, nokudaro ichitadzisa kuita ngura.
Polyethylene (PE) Coating: Kushandiswa kwePE coating kune kunze kwesimbi pombi kunowanzoshandiswa kune gasi rechisikigo uye mapaipi emafuta.Iyo yekupfekedza inodzivirira kemikari, inodzivirira mvura, uye ine yakanaka mechanical kudzivirira zvivakwa.
