Hordhac Product

Soo bandhigida adeegeena sare ee tuubooyinka biyaha, loogu talagalay in lagu daboolo baahiyaha kala duwan ee warshado kala duwan. Soo saara warshadeena casriga ah ee Cangzhou, Gobolka Hebei, shirkadeena ayaa hormuud u ahayd wax soo saarka tuubooyinka tan iyo markii la aasaasay 1993. Iyada oo aag ah 350,000 mitir oo laba jibbaaran iyo hantida guud ee RMB 680 milyan, waxaan ku faraxsanahay inaan haysano shaqaale u go'ay oo ah 680 xirfadlayaal xirfadlayaal ah.

OurDhuumaha biyaha ugu weynwaxaa loo naqshadeeyay waxqabadka ugu wanaagsan ee codsiyada muhiimka ah sida mareenada biyaha iyo khadadka gaaska. Waxaan fahamsanahay in qeexida tuubooyinkan, oo ay ku jiraan alxanka iyo naqshadaha tollaynta, ay door muhiim ah ka ciyaaraan shaqadooda iyo isku halaynta. Taasi waa sababta aan u isticmaalno farsamooyinka wax soo saarka sare iyo tallaabooyinka xakamaynta tayada adag si loo hubiyo in tuubooyinkeenu ay buuxiyaan heerarka warshadaha ugu sarreeya.

Biyo-xidheenka biyaha waxaa loogu talagalay inay noqdaan kuwo si heersare ah loogu adeegi karo oo la wada isticmaali karo, waxaana loo isticmaali karaa deegaanno kala duwan, taasoo ka dhigaysa inay ku habboon yihiin qandaraaslayaasha, degmooyinka, iyo codsiyada warshadaha. Haddi aad ku rakibayso biyo cusub ama aad hagaajinayso khad gaas oo jira, tuubooyinkeenu waxay bixiyaan adkeysiga iyo xoogga loo baahan yahay si loo daboolo baahida mashruuc kasta.

Faa'iidada Alaabta

Mid ka mid ah faa'iidooyinka aasaasiga ah ee tuubooyinka biyaha ee muhiimka ah waa ku-dhaqankooda sare. Waxa loo qaabeeyey in ay daboolaan baahiyaha degaannada kala duwan, taas oo ka dhigaysa kuwo ku habboon goobaha magaalooyinka iyo miyiga labadaba. Kala duwanaanshaha tuubooyinkan ayaa u oggolaanaya in loo isticmaalo codsiyo kala duwan, laga bilaabo sahayda biyaha degaanka ilaa gaadiidka gaasta warshadaha. La qabsigani aad buu muhiim ugu yahay degmooyinka iyo ganacsiyada si isku mid ah, maadaama ay fududayso soo iibsiga iyo hababka rakibaadda.

Nuqulka alaabta

Waxqabadka tubooyinkan waxaa saameyn kara arrimo ay ka mid yihiin xaaladaha ciidda, isbeddelka heerkulka, iyo heerarka cadaadiska. Tusaale ahaan, tuubooyinka alxanka ah ayaa laga yaabaa inay aad ugu nugul yihiin daxalka degaannada qaarkood, halka tuubooyinka tollaynta laga yaabo inaysan u adkeyn xaaladaha cadaadis sare. Fahamka xaddidaadyadan ayaa lagama maarmaan u ah injineerada iyo qorshayaasha si loo hubiyo in nooca saxda ah ee tuubada loo doortay codsi kasta oo gaar ah.

Codsiga

Muhiimadda ay leedahay in la isku halayn karo, tayo sare leh mareenada biyaha ee horumarinta kaabayaal mar walba sii kordhaya lama soo koobi karo. Loo yaqaan adeegyadooda sare, tuubooyinkani waxay lagama maarmaan u yihiin codsiyo kala duwan, oo ay ku jiraan tuubooyinka biyaha iyo gaaska. Tilmaamahooda, sida alxanka iyo naqshadaynta tollaynta, waxay door muhiim ah ka ciyaaraan hubinta waxqabadka ugu wanaagsan iyo nolosha adeegga.

Tuubooyinkeena ugu muhiimsan ee biyaha waxaa loo isticmaalaa codsiyo kala duwan, kuwaas oo ka muuqda meelo kala duwan. Haddi ay tahay nidaamka biyaha ee dawladda hoose ama shabakad qaybinta gaaska, tuubooyinkeenu waxay u adkeysan karaan dhibaatooyinka isticmaalka maalinlaha ah iyadoo la ilaalinayo waxtarka. Alxan iyotuubada tollayn spiraldoorashooyinku waxay bixiyaan dabacsanaan xagga codsiga ah, u oggolaanaya xalalka in la habeeyo si loo buuxiyo shuruudaha mashruuca ee gaarka ah.

FAQ

Q1. Waa maxay walxaha laga sameeyay tuubada ugu muhiimsan ee biyaha?

Dhexdhexaadiyaha biyaha waxaa badanaa laga sameeyaa walxo raagaya sida birta, PVC iyo HDPE. Doorashada maadada waxay kuxirantahay codsiga gaarka ah iyo xaaladaha deegaanka.

Q2. Waa maxay tuubooyinka alxanka leh iyo tuubooyinka tolitaanka spiral?

Tuubbada alxanka leh waxa ay samaysaa iyada oo la isku xidho labada gees ee tuubada, taas oo leh qaab dhismeed adag oo aan dillaacin. Tuubbada tollaynta spiral waxa ay samaysaa iyada oo fiilooyinka birta ah ee fidsan loo rogo qaab tuubo ah, taas oo leh dabacsanaan weyn xagga qaabaynta iyo codsiga.

Q3. Sideen ku dooran karaa dhuunta saxda ah ee mashruucayga?

Tixgeli arrimo ay ka mid yihiin nooca dareeraha la gudbiyo, shuruudaha cadaadiska, iyo xaaladaha deegaanka. La-talinta xirfadle waxay sidoo kale kaa caawin kartaa inaad hubiso inaad doorato tubbada ugu fiican ee baahiyahaaga.
