suma:
Spiral welded pombi chinhu chakakosha mumapurojekiti akasiyana ezvivakwa, anosanganisira mapaipi emafuta negesi, masisitimu ekutumira mvura, uye zvimiro zvekushandisa.Sezvakaita chero chigadzirwa chakagadzirwa, zvakatemwa zvinofanirwa kuteedzerwa kuti ive nechokwadi chekushanda uye kuvimbika kwemapombi aya.Muchibhurogu ichi, isu tichazeya mune intricacies yespiral welded pombi tsanangudzokupa gwara rakazara rekunzwisisa zviri nani ichi chakakosha maindasitiri chigadzirwa.
1. Tsanangudzo uye zvakanakira:
Nzira yekugadzira yespiral welded pipendiko kupinza tambo inopisa yakakungurutswa yesimbi kuita spiral shape nekuenderera mberi spiral kuumba.Mipendero yemipendero inobatanidzwa pamwe chete uchishandisa kaviri-sided submerged arc welding (DSAW) kuti iite pombi ine simba repamusoro nekusimba kwakawedzerwa uye kushorwa ku deformation.Mabhenefiti makuru e spiral welded pombi anosanganisira yakanakisa dhizaini kutendeseka, yunifomu kusimba pamwe nekureba kwepombi, uye kugona kutsungirira kumanikidzwa kwakanyanya kwemukati.
2. Diameter uye kukora kwemadziro:
Izvo zvinotsanangurwa zve spiral welded pombi dzinosanganisira dzakasiyana-siyana parameters, iyo inonyanya kukoshesa iyo dhayamita uye madziro emadziro epombi.Izvi zviyero zvinoenderana nezvinodiwa zvekushandisa uye mamiriro ekushanda.Kazhinji, spiral welded pombi inowanikwa mudhayamita yakakura pane isina musono kana kuti yakatwasuka seam welded pombi, kazhinji inotangira pa8 inches kusvika 126 inches (203.2 kusvika 3200 mm) kana hombe.Kukora kwemadziro kunotangira pa6mm kusvika 25.4 mm kana kudarika.
3. Simbi giredhi uye makemikari kuumbwa:
Kusarudzwa kwesimbi giredhi uye kuumbwa kwemakemikari kunoita basa rakakosha mukuona ma mechanika zvivakwa uye kuomarara kuramba kwe spiral welded pombi.Inowanzo shandiswa simbi mamakisi e spiral mapaipi anosanganisira API 5L X akatevedzana, ASTM A252 giredhi 2 uye 3, uye ASTM A139 giredhi B uye C. Aya magiredhi esimbi anotemerwa zvichibva pakusimba kwegoho uye yakaenzana nekabhoni kuti ive nechokwadi chekushanda kwakaringana mumashandisirwo chaiwo.
4. Kuedza uye kuongorora:
Kuti ive nechokwadi chemhando uye kuvimbika kwespiral welded pombi, vagadziri vanoomerera pakuyedzwa kwakasimba uye maitiro ekuongorora.Miedzo yakakosha yakaitwa inosanganisira hydrostatic bvunzo, isingaparadze kuyedza (senge ultrasonic kana radiographic inspection) uye mekiniki yekuyedza (tensile, goho uye kukanganisa kuyedza).Maedzo aya anovimbisa kuti mapaipi anosangana nesimba rinodiwa, saizi uye mazinga ekudonha.
5. Kuvhara uye kudzivirira:
Kuchengetedza spiral welded pombi kubva mukuora uye zvimwe zvinhu zvekunze, dzakasiyana siyana dzekuputira pamusoro dziripo.Aya machira anogona kusanganisira epoxy, coal tar enamel kana polyethylene, pakati pezvimwe.Pamusoro pezvo, nzira dzekudzivirira dze cathodic dzakadai seanode echibairo kana akaomeswa masisitimu azvino anogona kushandiswa kuchengetedza mapaipi.
Mukupedzisa:
Kunzwisisa spiral welded pombi yakatarwa kwakakosha kune mainjiniya, mamaneja epurojekiti uye vanobatanidzwa vanobatanidzwa mumapurojekiti ezvivakwa.Nekufunga nezve dhayamita, ukobvu hwemadziro, giredhi resimbi, kuyedzwa uye kuchengetedzwa kwepamusoro, unogona kuve nechokwadi chekuti pombi inosangana nezvinodiwa maitiro ekuita.Kuteerera kwakaringana nemakodhi hakungovimbisi hupenyu hurefu uye kuchengetedzeka kwepombi system yako, asi zvakare inovimbisa kufambisa kwakavimbika kwemvura, magasi uye zvimwe zvinhu.Kuburikidza nekutarisisa kune zvakadzama, mainjiniya nevatori vechikamu vanogona kuwana zvakabudirira zveprojekiti uku vachisangana nezvinodiwa zveindasitiri zviyero nemirairo.
