Imininingwane
I-ductile iron wide tolerance stepped coupling iwuhlobo lokuhlanganisa olusetshenziselwa ukuxhuma amapayipi amabili noma izixhumi ezinosayizi abahlukene.Yenziwe nge-ductile iron, okuwuhlobo lwe-cast iron eguquguqukayo futhi ehlala isikhathi eside kune-cast iron yendabuko.
Idizayini yokubekezelelana okubanzi kokuhlanganisa ivumela ububanzi obuningi bosayizi wamapayipi ukuthi buxhunywe, ukunciphisa isidingo sokuhlanganisa okuningi nokufakwa.Idizayini enezinyathelo zokuhlanganisa ihlinzeka ngokulingana okuvikelekile nokuqinile phakathi kwamapayipi, okuqinisekisa ukuxhumana okungavuzi.
I-Ductile iron wide tolerance stepped couplings ivame ukusetshenziswa ezindaweni zokuhlanza amanzi namanzi angcolile, kanye nasezimbonini ezinjengamapayipi kawoyela negesi.Asetshenziswa futhi ezinhlelweni zamapayipi kanye ne-HVAC ukuxhuma amapayipi anosayizi abahlukene.
Sekukonke, i-ductile iron wide tolerance stepped couplings iyisixazululo esinokwethenjelwa nesingabizi kakhulu sokuxhuma amapayipi anosayizi abahlukene, okuhlinzeka ngoxhumano oluvikelekile nolungavuziyo olungamelana nezidingo zezinhlelo zokusebenza ezihlukahlukene.
• Ububanzi obubanzi bangaphandle bobubanzi: isilinganiso esingu-21 mm ngokuhlangene.
• Inani elincane lamamodeli obubanzi obungajwayelekile.
• Ukwethembeka:
- Ukuvuza okuhlala njalo okuhlangene okuqinile lapho ucindezela i-gasket
phakathi kwe-flange yokuphela kanye nomkhono endaweni yepayipi.
- Ukuvikelwa kwe-Anticorrosion: i-epoxy powder coating (150 μm) kanye
I-Dacromet® 500 Gr.B yamabhawodi.
• Ukulula nesivinini sokufaka:
- Ukuchezuka kwe-angular ±6°.
- Imunca ukunwetshwa nokufinyela.
- Ivumela ukungahambi kahle.
- Igebe lezilungiselelo ezibalulekile.
• Ukuhambisana namazinga:
- NF A 48-830: Imikhiqizo ye-Foundry - I-Spheroïdal graphite cast iron
ukufakwa kwamapayipi amanzi okuphuza e-PVC ngaphansi kwengcindezi.
I-EN 545: Amapayipi ensimbi e-Ductile, okokufakwayo, izesekeli namajoyinti awo
amapayipi amanzi - izidingo kanye nezindlela zokuhlola.
I-ISO 2531: Amapayipi ensimbi e-Ductile, okokufakwayo, izesekeli namajoyinti awo
izicelo zamanzi.
• Ukugunyaza:
- Amanzi okuphuza avunyelwe.
• Qaphela:
Lokhu kuhlanganisa akumelani namandla e-longitudinal futhi qiniseka
ukuvinjelwa okwanele kunikezwa ukuvimbela ukugudluzwa kwamapayipi.
Idatha yobuchwepheshe
• Ibanga: DN 40/50 kuye ku-400.
• Ingcindezi yokusebenza ephezulu: PN 16.
• Amazinga okushisa: +0°C kuya +60°C.
• I-torque: 60 kuya ku-70 Nm.
Izinhlelo zokusebenza
• Amanethiwekhi amanzi okuphuza.
• Ukumpompa, ukwelashwa, ukugcinwa kwamanzi.
• Amanethiwekhi okuvikela umlilo.
• Amanethiwekhi okunisela.
• Amanethiwekhi endle kanye nemisele yamanzi emvula
(Uhlobo lwe-WC - EN 681-1).
Izivivinyo
• Ukuhlolwa kokuvala ngokuhambisana ne-ISO 2531 ejwayelekile.
