Amasistimu ahlukanisiwe ajwayelekile anikezela ngezikophu ezihlukene zohlelo lokusebenza, futhi ukugxila kwe-char yesisindo sepayipi akufani.
Namuhla sizoxoxa ngohlelo olujwayelekile lwe-EN lwe-EN10220.
Uhlolojikelele lwezinga le-EN 10220
I-EN 10220iyindinganiso yaseYurophu yobukhulu nokubekezelela amapayipi ensimbi angenamthungo nashiselwe.
Izinga le-EN 10220 linenhlobonhlobo yezinhlelo zokusebenza futhi lisetshenziswa kakhulu ezimbonini zikawoyela, igesi, amakhemikhali, ezokwakha, nezokuhlanza amanzi.
Izinga lihlanganisa ububanzi obungaphandle (OD) nokuqina kodonga (WT) lwamapayipi ensimbi, okuhlinzeka ngesethi ecacile yezinkombandlela kanye nokucaciswa okufanayo komklamo wobunjiniyela nokukhiqizwa ukuze kuqinisekiswe ukuvumelana nokushintshana kwemikhiqizo yamapayipi ekhiqizwa abakhiqizi abahlukene.
Izindlela Zokubala Isisindo
Indlela yokubala isisindo imitha ngeyunithi ubude inikezwe ku-EN 10220.
M=(DT)×Tx0.0246615
Mubukhulu beyunithi ngayinye ngo-kg/m,
Dubukhulu bangaphandle obushiwo ngo-mm,
Tubukhulu bodonga olushiwo ngo-mm.
Lesi sici sisekelwe ku-7.85 kg/dm3.(kg/dm3iyunithi yokuminyana, amadesimitha ayi-cubic.)
Amanani abaliwe angasetshenziswa futhi kumashubhu anamanani ahlukene okuminyana, kodwa kufanele aphindaphindwe nge-factor of
1.015 yensimbi engagqwali ye-austenitic (Lesi sici sisekelwe kubuningi buka-7.97 kg/dm3）.
0.985 yensimbi engagqwali ye-ferritic ne-martensitic (Lesi sici sisekelwe kubuningi buka-7.73 kg/dm3）.
Izibalo zingenziwa ngokusekelwe kumanani ahlukanisiwe wokuminyana eqenjini ngalinye lamabanga ensimbi engagqwali anikezwe ku-EN 10088-1.
Ukuhlukaniswa kochungechunge lwe-EN 10220
I-EN 10220ngokwezinga lokumiswa kwamapayipi kanye nezinsiza zawo.Kukhona uchungechunge oluthathu.
uchungechunge 1: amadayimitha angaphandle lapho zonke izesekeli ezidingekayo ekwakhiweni kwezinhlelo zamapayipi zilinganiselwe;
uchungechunge 2: amadayimitha angaphandle okungezona zonke izesekeli ezilinganiselwe;
uchungechunge 3: amadayamitha angaphandle lapho izinsiza ezimbalwa ezijwayelekile zikhona.
Amashadi esisindo samapayipi e-EN 10220 Series 1
Ipayipi OD yalolu chungechunge ilandela izindinganiso zamazwe ngamazwe noma zezimboni ncamashi, futhi imakethe inikeza ukufakwa okusezingeni eliphelele okufana nama-flange, ama-couplings, nezindololwane.
Lokhu kumiswa okuphelele kwenza kube lula ukuklama nokufaka inqubo futhi kunciphisa isidingo sezingxenye ezingajwayelekile kanye nezindleko zokwenza ngokwezifiso.
Amashadi esisindo samapayipi e-EN 10220 Series 2
Ingxenye ye-OD yalolu hlobo lwamapayipi imisiwe, kodwa akuzona zonke izinsimbi ezimisiwe.Okunye ukufakwa okujwayelekile, okufana nama-flange noma izindololwane, kungatholakala, kuyilapho ezinye izingxenye zingadinga ukwenziwa ngendlela oyifisayo, okunezela ezindlekweni nobunkimbinkimbi bephrojekthi.
Amashadi esisindo samapayipi e-EN 10220 Series 3
Lokhu kuvame ukuba njalo ngamasayizi amapayipi aqondile kakhulu noma angajwayelekile adinga inani elikhulu lokufakwa ngokwezifiso kanye nezingxenye, ukukhulisa izindleko zokuklama nokusebenzisa iphrojekthi, kanye nokwelula umjikelezo wokuthenga nokukhiqiza.
Amashadi Wesisindo Sombhobho Obukhulu Bodonga 70 -100 mm
Kumashubhu anezindonga eziwugqinsi anogqinsi olusuka ku-70 mm kuya ku-100 mm, izidingo zicaciswe ku-EN 10220, Ithebula 2.
Izesekeli zamashubhu esindayo odongeni anobukhulu ngokuhambisana neThebula 2 zingase zingatholakali kungakhathaliseki uchungechunge olukuThebula 1 lapho kwabelwa khona ububanzi obufanele bangaphandle.
Singabakhiqizi nabahlinzeki bepayipi lensimbi yensimbi esezingeni eliphezulu abavela eChina, futhi siphinde sibe nesitoko sepayipi sensimbi esingenamthungo, sikunikeza izixazululo eziningi zamapayipi ensimbi!
