Dulmar guud oo ku saabsan Tuubada Birta Ductile
Tuubooyinka birta ee Ductile waa tuubooyin laga sameeyay bir ductile ah. Birta Ductile waa bir graphite ah oo la shubay. Heerka sare ee ku tiirsanaanta birta ductile waxaa ugu horreyn sabab u ah xooggeeda sare, cimri dhererkeeda, iyo iska caabbinta saameynta iyo daxalka. Tuubooyinka birta ee Ductile waxaa caadi ahaan loo isticmaalaa qaybinta biyaha la cabi karo iyo bamgareynta slurries, wasakhda iyo kiimikooyinka habka loo farsameeyo. Tuubooyinkan birta ah waa horumar toos ah oo tuubooyinka birta ee hore loo shubay oo ay hadda ku dhowdahay inay beddesho. Heerka sare ee ku tiirsanaanta tuubooyinka birta ee ductile waa sababtoo ah sifooyinkeeda kala duwan ee sare. Tuubooyinkani waa tuubooyinka ugu badan ee loo raadsado dhowr jeer oo loo adeegsado.

Saddexda Fasal ee ugu Muhiimsan ee Tuubada Birta La Shubay
V-2 (fasalka 40) Birta Cawlan, V-3 (65-45-12) Birta Ductile, iyo V-4 (80-55-06) Birta Ductile. Waxay bixiyaan xoog cadaadis oo aad u fiican iyo awood qaboojin gariir oo sare.
V-2 (fasalka 40) Cawlan Birta, ASTM B48:
Heerkani wuxuu leeyahay xoog jiidis sare oo ah 40,000 PSI iyadoo xoogga riixitaanka uu yahay 150,000 PSI. Adkayntiisu waxay u dhaxaysaa 187 - 269 BHN. V-2 wuxuu ku habboon yahay codsiyada xidhashada tooska ah wuxuuna leeyahay xoogga ugu sarreeya, adkaanta, iska caabbinta xirashada iyo jawaabta daaweynta kulaylka ee birta cawlan ee aan la isku darin. Waxaa si weyn loogu isticmaalaa codsiyada qaadista iyo jarista ee warshadaha haydarooliga.
V-3 (65-45-12) Ductile Iron, ASTM A536:
Heerkani wuxuu leeyahay xoog jiidis ah oo ah 65,000 PSI, xoog wax soo saar oo ah 45,000 PSI, iyadoo la dheereynayo 12%. Adkaantu waxay u dhaxaysaa 131-220 BHN. Qaab-dhismeedkeeda ferritic-ga ee wanaagsan ayaa ka dhigaya V-3 mid ka mid ah kuwa ugu fudud ee lagu farsameeyo saddexda darajo ee birta ah taasoo ka dhigaysa mid ka mid ah heerarka ugu sarreeya ee lagu qiimeeyo mashiinnada kale ee birta; gaar ahaan marka lagu daro saameynta ugu fiican, daalka, korantada iyo sifooyinka marin-u-helka magnetic-ka. Birta Ductile, gaar ahaan tuubooyinka, waxaa ugu horreyn loo isticmaalaa khadadka biyaha iyo wasakhda. Birtan waxaa sidoo kale si caadi ah looga helaa qaybaha baabuurta iyo codsiyada warshadaha.
V-4 (80-55-06) Ductile Iron, ASTM A536:
Darajadani waxay leedahay xoog jiidis ah oo ah 80,000 PSI, xoog wax soo saar oo ah 55,000 PSI iyo dherer ahaan 6%. Waa xoogga ugu sarreeya saddexda darajo, sida shubka. Darajadani waxaa lagu daweyn karaa kulaylka ilaa 100,000 PSI xoog jiidis ah. Waxay leedahay qiimeyn machiniability oo 10-15% ka hooseysa V-3 sababtoo ah qaab-dhismeedkeeda pearlitic. Badanaa waxaa la doortaa marka loo baahdo fiisikiska birta.
Tuubooyinka DI way ka fiican yihiin tuubooyinka birta / PVC / HDPE
• Tuubooyinka DI waxay sidoo kale dhowr siyaabood u badbaadiyaan kharashyada hawlgalka oo ay ku jiraan kharashyada bamka, kharashyada tuubada, iyo burburka suurtagalka ah ee ka yimaada dhismaha kale, taasoo keenta cillad iyo kharashka dayactirka guud ahaan.
• Qiimaha wareegga nolosha ee Tuubooyinka DI waa mid ka mid ah faa'iidooyinkeeda ugu waaweyn. Maadaama ay sii jirto jiilal, ay dhaqaale ahaan u shaqeyso, oo si fudud oo hufan loo rakibo loona shaqeeyo, kharashka wareegga muddada dheer ama cimrigiisa si fudud ayuu uga hooseeyaa agab kasta oo kale.
• Tuubada birta ah ee isku-xidhka ah lafteedu waa walxo 100% dib loo warshadayn karo.
• Waa mid ku filan oo u adkaysan karta xaaladaha ugu daran, laga bilaabo isticmaalka cadaadiska sare, ilaa culeyska dhulka iyo taraafikada, ilaa xaaladaha ciidda aan degganayn.
• Rakibaadda waa mid fudud oo ammaan u ah shaqaalaha jari kara oo ku xiri kara tuubooyinka birta ah ee Ductile ee goobta yaalla.
• Dabeecadda birta ah ee Tuubada Birta Ductile waxay la macno tahay in tuubadu si fudud loogu meeleyn karo dhulka hoostiisa iyadoo la adeegsanayo qalabka raadraaca tuubooyinka caadiga ah.
•Tuubooyinka DI waxay bixiyaan xoog jiidis oo ka sarreeya birta khafiifka ah waxayna ilaaliyaan iska caabbinta daxalka ee birta la shubay.
