Faahfaahin
Isku-xidhka dulqaadka ballaadhan ee birta birta ah waa nooc ka mid ah isku xidhka loo isticmaalo in lagu xidho laba tuubbo ama qalabyo cabbirro kala duwan leh.Waxay ka samaysan tahay birta shubka ah, taas oo ah nooc ka mid ah birta shubka ah oo ka dabacsan oo ka adkaysi badan birta dhaqanka ah.
Naqshadeynta dulqaadka ballaaran ee isku-xirnaanta ayaa u oggolaanaysa in la isku xiro tiro badan oo cabbirro tuubo ah, taas oo yaraynaysa baahida isku-xirnaanta iyo xirmooyinka badan.Naqshadaynta talaabsan ee isku-xidhka ayaa bixisa isku xirnaan sugan oo adag oo u dhexeeya tuubooyinka, hubinta isku xirnaanta bilaa daadsan.
Isku-xireyaasha dul-qaadka ballaaran ee birta birta ah ayaa caadi ahaan loo adeegsadaa biyaha iyo dhirta lagu daweeyo biyaha wasakhda ah, iyo sidoo kale codsiyada warshadaha sida dhuumaha saliidda iyo gaaska.Waxa kale oo loo isticmaalaa tuubooyinka iyo nidaamyada HVAC si loogu xidho tuubooyinka cabbirrada kala duwan.
Guud ahaan, isku-xidhka dul-qaadka ballaaran ee birta birta ah ayaa ah xal la isku halayn karo oo kharash-ku-ool ah oo loogu talagalay isku xirka tuubooyinka cabbirrada kala duwan, iyagoo siinaya xiriir sugan oo aan dillaacin oo u adkeysan kara dalabaadka codsiyada kala duwan.
• Dhexroor ka baxsan oo ballaaran: celcelis ahaan 21 mm dhinac.
• Tiro yar oo moodallo ah oo loogu talagalay dhexroorka magaca ah.
Kalsoonida:
- Qulqulka joogtada ah ee wadajirka ah marka la cadaadiyo gaaska
inta u dhaxaysa cidhifka-dhamaadka iyo sleecada dusha tuubada.
- Ilaalinta Anticorrosion: daahan budada epoxy (150 μm) iyo
Dacromet® 500 Gr.B ee boolalka.
• Fududeynta iyo xawaaraha rakibidda:
- leexashada xagasha ± 6°.
- Waxay nuugtaa balaadhinta iyo foosha.
- Waxay dejisaa is-waafajinta khaldan.
- Farqiga dejinta muhiimka ah.
U hoggaansanaanta heerarka:
- NF A 48-830: Alaabooyinka aasaasiga ah - Spheroïdal graphite bir tuuray
qalabyada loogu talagalay tuubooyinka biyaha la cabbo ee PVC ee cadaadiska saaran.
TS EN 545 Tubooyinka birta-mareenka, qalabyada, qalabyada iyo kala-goysyada
dhuumaha biyaha - shuruudaha iyo hababka tijaabada.
TS EN ISO 2531 Tuubbooyinka birta ah ee birta ah, qalabyada, qalabyada iyo kala-goysyadooda
codsiyada biyaha.
Oggolaanshaha:
- Biyo la cabbo oo la oggolaaday.
Ogaysiis:
Isku dhafkan kama hortagayo xoogagga dhaadheer ee iska hubi
xakameyn ku filan ayaa la bixiyaa si looga hortago leexashada tuubooyinka.
