Immisa ayay miisaankeedu yahay Tuubada Birta Ductile

Injineernimada biyaha iyo dheecaanka, shabakadaha tuubooyinka degmada, iyo nidaamyada dhuumaha warshadaha,tuubo bir ah oo ductile ahwaxay noqotay beddel ku habboon tuubooyinka birta iyo birta ee dhaqanka ah sababtoo ah sifooyinkeeda farsamada ee aadka u fiican iyo iska caabbinta daxalka. Fahmidda xuduudaha farsamada ee muhiimka ah ee tuubada birta ee ductile waa mid muhiim u ah naqshadeeyayaasha, iibsadayaasha, iyo shirkadaha dhismaha, ha ahaato kuwa biyaha keena ama kuwa biyaha qaada. Maqaalkani wuxuu qaadan doonaaTuubo bir ah oo DINSEN ah oo ductile ahTusaale ahaan si nidaamsan loogu sharaxo qeexitaankiisa, miisaankiisa, cadaadiska shaqada, iyo astaamaha dahaarka.

I. Tilmaamaha iyo Cabbirka Tuubada Birta Ductile: Sidee loo Go'aamiyaa Nooca?

Marka la dooranayo tuubooyinka, marka hore waxaa lagama maarmaan ah in la caddeeyo cabbirka iyo cabbirka tuubooyinka birta ah ee ductile. Heerarka caalamiga ah waxay inta badan ku salaysan yihiin ISO 2531 ama EN 545, oo lagu kala saaray dhexroorka magacaaban (DN).

Tusaale ahaan, tuubooyinka birta ah ee DINSEN ductile, heerka K9 (heerka dhumucda derbiga caadiga ah) ayaa si caadi ah loo isticmaalaa, iyadoo dhexroorkoodu u dhexeeyo DN80 ilaa DN2000. Waa kuwan cabbirrada tuubooyinka caadiga ah:

• DN80: Dhexroorka dibadda 98mm, dhumucda derbiga 6.0mm
• DN100: Dhexroorka dibadda 118mm, dhumucda derbiga 6.0mm
• DN200: Dhexroorka dibadda 222mm, dhumucda derbiga 6.3mm
• DN400: Dhexroorka dibadda 429mm, dhumucda derbiga 8.1mm
• DN1000: Dhexroorka dibadda 1048mm, dhumucda derbiga 13.5mm

Noocyada kala duwan ee dhumucda derbiga (K8, K9, K10, K12) waxay saameyn doonaan awoodda cadaadiska iyo miisaanka halbeegga ee tuubadaIsticmaalayaashu waxay si habboon u dooran karaan iyadoo loo eegayo cadaadiska naqshadeynta.

II. Miisaanka halkii mitir ee tuubada birta ah ee ductile: Immisa ayuu miisaankeedu yahay tuubada birta ah ee ductile?

Su'aal caadi ah oo ku saabsan soo iibsiga injineernimada ayaa ah: Immisa ayuu miisaankiisu yahay tuubada birta ah ee ductile? Miisaanka tuubada birta ah ee ductile wuxuu ka kooban yahay miisaanka jidhka tuubada iyo miisaanka godka, taasoo si toos ah u saamaysa kharashka gaadiidka, kor u qaadista, iyo rakibidda.

Tusaale ahaan, iyadoo la adeegsanayo tuubo bir ah oo ductile ah oo heerka DINSEN K9 ah (dhererka caadiga ah ee 6 mitir) miisaanka aragtiyeed waa sidan soo socota:

• DN100: Qiyaastii 15.1 kg/m → 95 kg halkii tuubo
• DN200: Qiyaastii 30.6 kg/m → 194 kg halkii tuubo
• DN300: Qiyaastii 50.8 kg/m → 323 kg halkii tuubo
• DN500: Qiyaastii 104.3 kg/m → 669 kg halkii tuubo
• DN800: Qiyaastii 215.2 kg/m → 1394 kg halkii tuubo

Miisaanka dhabta ah wuu kala duwanaan karaa sababo la xiriira arrimo ay ka mid yihiin dhumucda dahaarka zinc iyo dahaarka hoobiyaha sibidhka ee gudaha. DINSEN waxay bixin kartaa xaashiyo xisaabin miisaan oo sax ah oo loogu talagalay miisaaniyadda mashruuca iyo qorsheynta saadka.

III. Cadaadiska Shaqada ee Tuubada Birta Ductile

Tuubada birta ah ee ductile-ka waxay leedahay xoog jiidis sare iyo xoog cadaadis wareegsan. Tuubada birta ah ee ductile-ka ee heerka K9 caadi ahaan waxay leedahay cadaadis shaqo oo ah 16 bar (1.6 MPa), halka darajooyinka dhumucda derbiga ee sare (sida K12) ay ku habboon yihiin codsiyada cadaadiska ee 25 bar ama xitaa 40 bar.

Tuubooyinka birta ah ee DINSEN ductile waxaa si adag loo sameeyaa iyadoo la raacayo heerarka ISO 2531. Tuubo kasta waxaa la mariyaa tijaabo hydrostatic ah ka hor inta aysan ka bixin warshadda si loo hubiyo in ay leedahay khatar badbaado oo 1.5 jeer ka sarreysa cadaadiska shaqada naqshadda, taasoo ka dhigaysa mid si gaar ah ugu habboon gudbinta biyaha masaafada dheer, tuubooyinka saldhigga bamgareynta, iyo dhuumaha warshadaha ee cadaadiska sare leh.

IV. Dahaarka Zinc ee Ilaalinta Daxalka

Doorka Dahaarka Zinc ee Tuubooyinka Birta Ductile Mid ka mid ah tallaabooyinka ilaalinta ugu muhiimsan ee dhuumaha aasan waa dahaarka zinc ee tuubooyinka birta ductile. Dahaarka zinc ma aha oo kaliya inuu bixiyo ilaalin katoolik ah laakiin sidoo kale wuxuu sameeyaa nidaam isku dhafan oo ka hortagga daxalka oo leh rinji dibadeed ama dahaarka polyethylene.

Tuubooyinka birta ah ee DINSEN ductile waxay la yimaadaan heer caadi ah oo leh dahaar zinc ah oo ≥200 g/m² ah (sida waafaqsan heerka ISO 8179), oo lagu daboolay lakabka cas ee epoxy ama polyurethane, taasoo si weyn u hagaajinaysa iska caabbinta daxalka iyo cimriga. Carrada daxalka leh ama meelaha iska caabbinta sare leh, dahaar zinc dheeraad ah + filim PE ah ama dahaar polyurethane oo buuxa ayaa la heli karaa, oo leh cimri adeeg oo loogu talagalay 50-100 sano.

V. Maxaad u Dooranaysaa Tuubooyinka Birta Ductile ee DINSEN?

Iyada oo ah alaab-qeybiye tuubo bir ah oo xirfad leh, DINSEN waxay bixisaa noocyo kala duwan oo qeexitaanno ah laga bilaabo DN80 ilaa DN2000, iyadoo taageereysa dhumucda derbiga kala duwan sida K8, K9, K10, iyo K12, waxayna habeyn kartaa dhererka, dahaarka gudaha (mashiinka sibidhka/resin epoxy), iyo xalalka ilaalinta daxalka dibadda si loo daboolo baahiyaha macaamiisha.

Dhammaan tuubooyinka birta ee ductile-ka ah waxaa shahaado ka haysta ISO 2531 / EN 545. Jadwallada oo dhammaystiran oo ku saabsan miisaanka, cabbirka, cadaadiska shaqada, iyo xuduudaha dahaarka zinc-ka ayaa la heli karaa. Baakadaha dhoofinta caalamiga ah iyo adeegyada saadka hal-joojin ah ayaa la taageeraa.
