EPC & Mapaipi emiti:Mapombi ekugadzirisa zvinhu nekushandisa muzvicherwa, mafekitori ekugadzirisa gasi, makemikari, uye nzvimbo dzekugadzira magetsi.
9. Kurongedza & Kutumira
Mapaipi eERW anorongedzwa uye anotumirwa nekungwarira kukuru kuti ave nechokwadi chekuti akachengetedzwa panguva yekufambisa. Heino tsananguro yemaitiro ekurongedza nekutumira:
Kurongedza:
Kudzivirira Kupfeka:Pamberi pekurongedza, mapaipi anogona kuputirwa neoiri yekudzivirira ngura kana varnish inodzivirira ngura pamusoro pezvinhu kuti isaparare kana kuomeswa panguva yekuchengetera nekufambisa zvinhu. Kupedzwa kusina chinhu kunowanikwawo kuti kupetwe nekukasira panzvimbo yaunoda.
Kubatanidza:Mapaipi ane saizi dzakafanana uye zvirevo zvakafanana anobatanidzwa pamwe chete nemazvo muzvikamu zvehexagonal kana rectangular. Anobatanidzwa netambo dzesimbi (kazhinji tambo nhatu kusvika kushanu pachikamu chimwe nechimwe) kudzivirira kufamba mukati mechikamu.
Magumo Ekupedzisira:Zvivharo zvepurasitiki (PE kana PP) zvinoiswa kumativi ese epombi yega yega kudzivirira magumo akachekwa, magumo asina kujeka, uye zvinobatanidzwa zvine shinda kubva pakukuvadzwa, kupinda kwemarara, uye hunyoro.
Kuisa padhi neKuisa padhishioni:Pakutenga zvinhu zvinotengeswa kunze kwenyika zviri premium, zvinhu zvepadding zvakaita sefoam rings kana rabha zvinogona kushandiswa pakati pemapaipi kudzivirira kukweshana uye kukuvara kwependi panguva yekubata.
Mabhokisi kana Makasi emapuranga:Pamapaipi ane madziro matete, machubhu akanyatsogadzirwa, kana machira epamusoro-soro, mapaipi anogona kuiswa mumabhokisi emapuranga akasimba kana mabhokisi eplywood kuti ape dziviriro yakasimba kubva kumasimba ekunze uye kubata kwakaomarara.
Kutumira:
Nzira Yekufambisa:Mapaipi anotumirwa nemidziyo yemumagaba (20ft/40ft), zvinhu zvinotakura zvinhu zvakawanda, kana zvinhu zvechitima zvichienderana nekwavanoenda, huwandu, uye kudiwa kwekukurumidzira. Zvinhu zvinotakura zvinhu nendege zviripo kuti zvitumirwe nemuenzaniso kana kuti panguva yakakodzera.
Kuisa mumidziyo:Maodha madiki kusvika pakati nepakati akaiswa mumakontena ekutakura zvinhu akajairwa, achidzivirira zvinhu kubva kumamiriro ekunze, hunyoro, uye tsvina yekunze panguva yekufambisa.
Kutakura Ngarava Yakawanda:Maodha makuru (anowanzo svika matani mazana maviri) anotakurwa zvakananga mumidziyo yekutakura zvinhu. Matanda ekusimudza nemidziyo yekupararira anodzivirira kukuvara; anobvisa matombo uye anosunga zvinhu zvakasimba kuti zvisafambe mugungwa.
Kunyora Mazita & Kunyora Zvinyorwa:Paketi yega yega yakanyorwa zvakajeka negiredhi, chiyero, saizi, nhamba yekupisa, uye mirairo yekubata. Magwaro akazara (inisiti yekutengeserana, runyorwa rwekurongedza, bhiri rekutakura zvinhu, Chitupa Chekubva, Zvitupa Zvekuyedza Mill) akagadzirirwa kubvumidzwa zvakanaka kwemutero.
Kusunga Kwakachengeteka:Mapaketi akabatanidzwa nesimbi, mabhegi emudura, kana matanda ekudzivirira kusuduruka, kukunguruka, kana kukuvara panguva yekufambisa.
Kutevera & Inishuwarenzi:Nhamba dzekutevera makontena dzakapihwa kuti dzitariswe panguva chaiyo. Inishuwarenzi yekutakura zvinhu mugungwa (Njodzi Dzose kana Neavhareji) inowanikwa kana yakumbirwa.
Muchidimbu, Womic Steel inoita shuwa kuti mapaipi ese eERW Steel akafukidzwa nematanho ekudzivirira anotungamira muindasitiri uye anotumirwa achishandisa nzira dzakavimbika dzekufambisa kuti asvike kwaanoenda ari mumamiriro akanaka. Maitiro akakodzera ekurongedza nekutumira akakosha kuchengetedza kunaka uye hunhu hwezvigadzirwa zvinounzwa.

Sei Uchifanira Kushanda NeWomic Steel?
Chitoro Chinopa Zvinhu Zvose:Mhando dzakasiyana-siyana kubva pamapaipi eAPI 5L ERW kusvika kuzvinhu zvinoenderana neOEM pipe fittings (Elbows, Tees, Reducers, Flanges, Caps) mumhando dzakasiyana dzezvinhu, zvinosanganisira carbon steel, alloy steel, uye stainless steel.
Kutevedzera Mutemo weUnyanzvi:Zvitupa Zvekuyedza Zvigayo Zvakazara (EN 10204 Type 2.2, 3.1, kana 3.2) zvinopihwa pamwe chete nekutumira kwega kwega, zvichiratidza kuumbwa kwemakemikari chaiwo, mhedzisiro yebvunzo yemakanika, uye mishumo yekuongorora isingaparadze.
Mabasa Akawedzerwa Kukosha:Kuvhara mativi (30°-35°), kubatanidza neshinda, kuisa mapurasitiki, uye jira rinodzivirira ngura (FBE, 3LPE, 3LPP, Epoxy, Galvanizing) zvinowanikwa mukati meimba kana kuburikidza nenzvimbo dzekudyidzana dzakanyatsokodzera.
Kukwikwidzana Kwezvinhu:Kushanda pamwe chete nemakambani anotakura zvinhu pasi rose kunoita kuti zvinhu zvitakurwe zvakanaka (kuwedzera huwandu hwezvinhu pamudziyo mumwe nemumwe) uye kuti zvinhu zvitakurwe pasi rose zvisingadhuri uye nguva dzekutakura dzakavimbika.
Zvinhu zviri mudura uye Kuwanikwa kwazvo:Kuwanda kwemasaizi akajairwa eAPI 5L X52 (2"-24" OD, Schedule 10-80) kunovimbisa nguva pfupi yekushanda uye mhinduro nekukurumidza kune zvinodiwa zvepurojekiti nekukurumidza. Saizi dzakagadzirwa kana dzadikanwa nenguva yenguva yakatarwa yekushanda kwemazuva 30-45.
Kugona Kwebasa Rakaoma:Kukwanisa zvizere kupa mapombi ePSL2 ane HIC neSSC bvunzo zvichienderana neNACE standards yekushandisa gasi rinonaka. Kuomarara kunodzorwa kusvika ≤ 248 HV10 / ≤ 22 HRC.

Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)
Mubvunzo: Ndeupi musiyano uripo pakati peASTM A178 GR.A, GR.C, uye GR.D?
A: GR.A ine kabhoni yakaderera (0.10% max) uye simba (330 MPa) - kugona kuumbwa zvakanaka pakukombama. GR.C ine kabhoni yakawanda (0.18% max) uye simba (415 MPa) - inonyanya kushandiswa. GR.D ine kabhoni yakawanda (0.27% max) uye simba (415 MPa ine goho rakakura) - yekushandisa pressure yakakwira.
Mubvunzo: Ndeupi musiyano uripo pakati pemachubhu eboiler eASTM A178 (akasungirirwa) neASTM A179 (asina musono)?
A: A178 inosungirirwa nemagetsi (ERW) - inodhura zvishoma, yakakodzera kushandiswa kwemabhoyira akawanda. A179 inodhonzwa zvakanaka inotonhorera - kana paine kumanikidzwa kwakanyanya kana kuti isina mvumo yekusungirirwa. Ose ari maviri akajairika mubhoyira uye muchina wekuchinjana kupisa.
Mubvunzo: Ndedzipi bvunzo dzinodiwa pamachubhu eboiler eASTM A178?
A: Kuyedzwa kwemvura (chubhu yega yega), kuyedzwa kwekutsanura, kuyedzwa kwekupenya, uye kuyedzwa kwekutsinhana kwemhepo kwakachinjika kana kuti kwenguva refu. NDT (UT kana ET) inogona kutsanangurwa nemutengi. Womic Steel inoita bvunzo dzese dzinodiwa zvichienderana neASTM A178.
Mubvunzo: A178 GR.A ingashandiswa here pamachubhu e superheater?
A: Hongu, asi zvinongogumira pakupisa kuri pakati nepakati. Kune sevhisi yekupisa kwakanyanya, GR.C kana GR.D inokurudzirwa. GR.A ndiyo yakanakira machubhu emvura ebhoyira uye economizer ane tembiricha yakaderera.
Mubvunzo: Ndeipi tembiricha yepamusoro yekushanda yeA178 GR.A?
A: Kazhinji kusvika ku400°C (750°F) kuti irambe ichishandiswa. Kana paine tembiricha yakakwira, funga nezve GR.C kana magiredhi e alloy akadai seA213 T11 kana T22. Tarisa kodhi yekugadzira kuti uwane miganhu chaiyo yetembiricha.
Mubvunzo: Chii chinonzi flaring test uye nei ichikosha?
A: Kuedza kupenya kunowedzera magumo echubhu uchishandisa mandrel yakatetepa kusvika pahuwandu hwakatarwa (kazhinji 15-30%). Izvi zvinoongorora kusimba uye kunaka kwechubhu, zvichiita kuti pasave nekutsemuka panguva yekuisa chubhu yeboiler.
Mubvunzo: Munogona here kuongorora machubhu eA178 GR.A kubva kune vamwe vanhu?
A: Ehe. Kuongororwa neSGS, BV, TÜV, ABS, DNV, LR kuripo. Zvitupa 3.2 zvinopihwa kana zvakumbirwa. Kuona bvunzo ye hydrostatic, bvunzo ye flaring, uye bvunzo ye flattening kuripo.
Q: Ndeipi nguva yakajairika yekuisa machubhu eASTM A178 GR.A?
A: Saizi dzezvitoro: mazuva 15-25. Saizi dzakagadzirwa nevatengi: mazuva 30-45. Kuongorora kwevamwe kunowedzera mazuva 5-10. Maodha ekukurumidza anowanikwa pahuwandu hushoma.
Mubvunzo: Ndeapi magwaro amunopa?
A: Chitupa Chekuyedza Chigayo (EN 10204 Type 3.1), mushumo wekuyedza we hydrostatic, mushumo wekuyedza we flaring/flattening, mushumo we dimensional, list yekurongedza, invoice, bhiri rekutakura zvinhu.
