Izinhlelo ezahlukene ezijwayelekile zinikeza ububanzi obuhlukene bokusetshenziswa, futhi ukugxila kwe-char yesisindo sepayipi akufani.
Namuhla sizoxoxa ngohlelo olujwayelekile lwe-EN lwe-EN10220.
Ukubuka konke kwe-EN 10220 standard
I-EN 10220iyindinganiso yaseYurophu yobukhulu nokubekezelelana kwamapayipi ensimbi angenamthungo nashibilikisiwe.
Izinga le-EN 10220 linezindlela eziningi zokusetshenziswa futhi lisetshenziswa kakhulu embonini kawoyela, igesi, amakhemikhali, ezokwakha kanye nezokuhlanza amanzi.
Indinganiso ifaka ububanzi bangaphandle (OD) kanye nobukhulu bodonga (WT) lwamapayipi ensimbi, enikeza isethi ecacile yeziqondiso kanye nemininingwane efanayo yokuklama nokukhiqiza kobunjiniyela ukuqinisekisa ukuvumelana kanye nokushintshana kwemikhiqizo yamapayipi ekhiqizwa abakhiqizi abahlukene.
Izindlela Zokubala Isisindo
Indlela yokubala isisindo ngemitha ngobude beyunithi ngayinye inikezwe ku-EN 10220.
M=(DT)×Tx0.0246615
Mubude besisindo ngeyunithi ngayinye buyi-kg/m,
Dububanzi obungaphandle obucacisiwe ku-mm,
Tukujiya kodonga okucacisiwe ngo-mm.
Lesi sici sisekelwe ekubuneni okungu-7.85 kg/dm3.(kg/dm3iyiyunithi yobuningi, ama-cubic decimeter.)
Amanani abaliwe angasetshenziswa futhi kumashubhu anamanani ahlukene obuningi, kodwa-ke kufanele aphindwe ngesilinganiso se-
1.015 yensimbi engagqwali ye-austenitic（Lesi sici sisekelwe ekubuneni okungu-7.97 kg/dm3）.
0.985 yensimbi engagqwali ye-ferritic ne-martensitic（Lesi sici sisekelwe ekubuneni okungu-7.73 kg/dm3）.
Izibalo zingenziwa ngokusekelwe kumanani ahlukanisiwe wobuningi beqembu ngalinye lamagreyidi ensimbi engagqwali anikezwe ku-EN 10088-1.
Ukuhlukaniswa Kochungechunge lwe-EN 10220
I-EN 10220ngokwezinga lokumiswa kwamapayipi kanye nezesekeli zawo. Kunezinhlobo ezintathu zochungechunge.
uchungechunge 1: ububanzi bangaphandle lapho zonke izesekeli ezidingekayo ekwakheni izinhlelo zamapayipi zilinganiselwe khona;
uchungechunge 2: ububanzi bangaphandle okungezona zonke izesekeli ezilinganiselwe;
uchungechunge 3: ububanzi bangaphandle lapho kukhona khona izesekeli ezijwayelekile ezimbalwa kakhulu.
Amashadi esisindo sepayipi e-EN 10220 Series 1
I-OD yamapayipi yalolu chungechunge ilandela izindinganiso zomhlaba wonke noma zemboni ngqo, futhi imakethe inikeza izinto zokufakelwa ezijwayelekile ngokugcwele njenge-flanges, couplings, kanye ne-elbow.
Lokhu kulungiswa okuphelele kwenza inqubo yokuklama nokufaka ibe lula futhi kunciphisa isidingo sezingxenye ezingezona ezejwayelekile kanye nezindleko zokwenza ngokwezifiso.
Amashadi esisindo sepayipi e-EN 10220 Series 2
Ingxenye ye-OD yalolu hlobo lwamapayipi ijwayelekile, kodwa akuzona zonke izinto ezijwayelekile. Ezinye izinto ezijwayelekile, njenge-flanges noma i-elbow, zingatholakala, kanti ezinye izingxenye zingadinga ukwenziwa ngokwezifiso, okwengeza ezindleleni nasebunzimeni bephrojekthi.
Amashadi esisindo sepayipi e-EN 10220 Series 3
Lokhu kuvame ukuba njalo ngosayizi wamapayipi athile kakhulu noma angajwayelekile adinga inani elikhulu lezinto zokufakelwa kanye nezingxenye ezenziwe ngokwezifiso, okunyusa izindleko zokuklama nokusebenzisa iphrojekthi, kanye nokwandisa umjikelezo wokuthenga nokukhiqiza.
Amashadi Esisindo Sepayipi Lobukhulu Bodonga 70 -100 mm
Kumapayipi anodonga olujiyile anobukhulu bodonga obusukela ku-70 mm kuya ku-100 mm, izidingo zichazwe ku-EN 10220, Ithebula 2.
Izesekeli zamapayipi odonga asindayo anobukhulu obuhambisana neThebula 2 zingase zingatholakali kungakhathaliseki ukuthi uchungechunge olukuThebula 1 lunikezwe ububanzi obufanele bangaphandle.
Singumkhiqizi kanye nomhlinzeki wamapayipi ensimbi yekhabhoni ashiselwe ngekhwalithi ephezulu avela eShayina, futhi siphinde sibe ngumthengisi wamapayipi ensimbi angenamthungo, sikunikeza izixazululo eziningi zamapayipi ensimbi!
amathegi: en 10220, ishadi lesisindo sepayipi, Uchungechunge 1, abahlinzeki, abakhiqizi, amafektri, abathengisi bamasheya, izinkampani, ngobuningi, ukuthenga, intengo, ikhotheshini, inqwaba, yokuthengisa, izindleko.
