Kunzwisisa zvakapetwa kaviri pombi uye spiral welded simbi pombi astm a252
Nhungamidzo:
Munharaunda yazvino, kutakura kwakashanda kwezvinwiwa uye magasi kwakakosha kune maindasitiri akawanda. Chimwe chezvinhu zvakakosha mukuona kushanda kwakanaka kweakoPipe Line Systemiri kusarudza mapaipi akanaka. Pakati pezvisarudzo zvakasiyana siyana zviripo, S235 JR Spiral Steel pombi isarudzo yakavimbika nekuda kwemhando yepamusoro. Iyi blog inovavarira kuongorora zvakanakira kushandisa S235 JR Spiral Steel pombi muPiping Systems, kutarisa pane yayo yakasarudzika chimiro.

Hydrostatic test
Kureba kwepepe kuchaidzwa nemugadziri kune hydrostatic kumanikidza kuchagadzira madziro kushushikana kwekushaiwa makumi matanhatu muzana yeiyo yakasarudzika shuwa simba rekubereka tembiricha. Dzvinyiriro ichatsanangurwa neiyo inotevera equation:
P = 2st / d
Zvinotenderwa kusiyana kwehuremu uye zviyero
Kureba kwega kwega kwepepe kucharemerwa zvakasiyana uye kurema kwayo hakuzopindiri kupfuura gumi muzana pamusoro kana 5.5% pasi pehuremu hwayo uye huremu hwayo uye huremu hwayo pane urefu hwakareba
Iyo yekunze dhisiki haizosiyane kupfuura ± 1% kubva pane yakatarwa zita rekunze kunze kwedhimoni
Kukudza kwemadziro chero nguva hakuzopfuura kusvika pagumi nemaviri% pasi peiyo yakataurwa madziro madziro
1. Nzwisisa S235 JR Spiral Steel Pipi:
S235 JR Spiral Steel pombiipombi yemapipi yakasarudzika yakashandiswa zvakanyanya mumapipi masisitimu. Ivo vakagadzirwa nesimbi-yepamusoro simbi mukuteerera zviyero zvepasi rese, vachiratidza kusimba kwakakwirira uye kusimba. Maitiro ekugadzira anosanganisira kuumbwa kwekunyepedzera kwekuenderera mberi kwesimbi mitsetse, iyo yakazotorwa kusvika pakureba. Uku kuchinja kwehunyanzvi kunopa mapaipi ane zvakanakira zvakanakira pamusoro pemubhadharo wakananga-seam.

Iyo Spiral Watched Kuvakwa kweS235 JR Spiral Steel pombi inopa akawanda mabhenefiti ekupa masisitimu. Chekutanga, iyo inoenderera ichitenderera tels seams inosimudzira kutendeka kwechimiro kwepombi, ichiita kuti ive inodzivirira zvakanyanya kune zvemukati uye zvekunze zvinonhuhwirira. Ichi chimiro chinogonesawo kunyange kugovera kugoverwa, kuderedza njodzi yekutadza pombi. Uye zvakare, iyo yekunyepedzera yeiyo pombi inobvisa kudiwa kwekusimbiswa kwemukati, nekudaro optimizing mafambiro ekuyerera uye kuderedza kurasikirwa kwekumanikidza panguva yekufambisa. Iyo isina kusarudzika inoenderera pamusoro penzvimbo yekupenga inoderedza njodzi yekukasira uye inovandudza kuchengetedzeka uye nekubudirira kweiyo pombing system.
3. Simbisa Kugadzwa uye Kuwedzera:
S235 JR Spiral Steel pombi inopa yakakwirira kusimba nekuda kwezvakakwirira zvekuvaka zvemhando yepamusoro. Ivo vanopokana kuCorrosion, Abraasion uye akanyanya mamiriro ekunze mamiriro ezvinhu, achivaita kuti vakwanise kuita zvakasiyana-siyana zvekushandisa zvinosanganisira mafuta uye gasi rekufambisa, masisitimu emvura uye mapurojekiti emvura uye marapuro emvura uye marapuro emvura. Iko kuwanda kweiyi pombi kunovatendera kuti vave nyore kugadziriswa kuti vasungane chaizvo projekiti zvinodiwa. Pamusoro pezvo, ivo vari nyore kuisa uye kuchengetedza, kuwedzera kuwedzera kukurudzira kwavo uye kubatsira kuti vagadzikane mune imwe mutengo-inobudirira uye inoshanda Ductwork system.
4. Kubatsirwa kwezvakatipoteredza uye kusimba:
Kuchinjira kuS235 JR Spiral Steel Pombi muPIGINS Systems inogona zvakare kuunza zvikwanisiro zvakakosha zvemamiriro ekunze. Hupenyu hwavo hurefu uye kuramba kusvibiswa kuderedza kukosha kwekugara uchitsiva, zvichikonzera kuderera kabhoni emishini uye chizvarwa chidiki. Pamusoro pezvo, kudzokorodza kwesimbi kunoita kuti aya ape pombi yakasimba sarudzo mumutsara nedenderedzwa hupfumi humbowo hunhu. Nekushandisa S235 JR Spiral Steel Pipe, Maindasitiri anogona kuve nechokwadi chakaringana hushamwari uye nenzira ine mutoro yekutakura mvura, nekudaro inosimudzira ramangwana rakasvibirira.
Mhedziso:
Kushandiswa kweS235 JR Spiral Steel Pombi muPIPINS Systems inopa huwandu hwenzvimbo dzakakosha, kusanganisira kushamisika kusimba, kuchengeteka uye kushanda zvakanaka. Chimiro cheSpiraled Welded inofunga kutendeka kwayo uye inopa yakavimbika yehunhu hwekutumira kwemaindasitiri akasiyana siyana. Nekubatanidza matekinoroji epamberi seiyi, isu tiri kuisa nzira yekuwedzera uye yakavimbika pombiges system.
