Ingakanani I-Ductile Iron Pipe Enzima​

Kwinjineli yokubonelela ngamanzi kunye nokuhambisa amanzi, iinethiwekhi zemibhobho kamasipala, kunye neenkqubo zemibhobho yemizi-mveliso,umbhobho wesinyithi othambileyoiye yaba yindawo efanelekileyo yokuthatha indawo yeepayipi zesinyithi zemveli kunye neepayipi zentsimbi ngenxa yeempawu zayo ezibalaseleyo zoomatshini kunye nokumelana nokugqwala. Ukuqonda iiparameter zobugcisa eziphambili zepayipi yesinyithi ethambileyo kubalulekile kubayili, abathengi, kunye neenkampani zokwakha, nokuba zezokuhambisa amanzi okanye ukuthuthwa kwamanzi amdaka. Eli nqaku liza kuthathaUmbhobho wesinyithi we-DINSEN ductilenjengomzekelo wokuchaza ngokwenkqubo iinkcukacha zayo, ubunzima, uxinzelelo lokusebenza, kunye neempawu zokugquma.

I. Iinkcukacha kunye nobukhulu beDuctile Iron Pipe: Ungayichonga njani iModeli?

Xa ukhetha imibhobho, kufuneka kuqala ucacise ubungakanani kunye nobukhulu bombhobho wesinyithi othambileyo. Imigangatho yamazwe ngamazwe isekelwe kakhulu kwi-ISO 2531 okanye kwi-EN 545, ehlelwe ngokwe-nominal diameter (DN).

Xa sijonga umbhobho wesinyithi othambileyo we-DINSEN njengomzekelo, imibhobho ye-K9 grade (ubungakanani bodonga obuqhelekileyo) isetyenziswa kakhulu, kunye nobubanzi obuqhelekileyo obuqala kwi-DN80 ukuya kwi-DN2000. Nazi ezinye zeendlela eziqhelekileyo zobukhulu bemibhobho:

• DN80: Ububanzi bangaphandle yi-98mm, ubukhulu bodonga yi-6.0mm
• DN100: Ububanzi bangaphandle yi-118mm, ubukhulu bodonga yi-6.0mm
• DN200: Ububanzi bangaphandle yi-222mm, ubukhulu bodonga yi-6.3mm
• DN400: Ububanzi bangaphandle yi-429mm, ubukhulu bodonga yi-8.1mm
• DN1000: Ububanzi bangaphandle yi-1048mm, ubukhulu bodonga yi-13.5mm

Amanqanaba ahlukeneyo obukhulu bodonga (K8, K9, K10, K12) aya kuchaphazela amandla okuthwala uxinzelelo kunye nobunzima beyunithi yombhobho.Abasebenzisi banokukhetha ngokufanelekileyo ngokwengcinezelo yoyilo.

II. Ubunzima ngemitha nganye yombhobho wesinyithi othambileyo: Ubunzima bombhobho wesinyithi othambileyo bubungakanani?

Umbuzo oqhelekileyo ekuthengweni kobunjineli ngulo: Ubunzima bombhobho wesinyithi othambileyo bubungakanani? Ubunzima bombhobho wesinyithi othambileyo buquka ubunzima bomzimba wombhobho kunye nobunzima besokethi, nto leyo echaphazela ngokuthe ngqo iindleko zothutho, ukuphakamisa, kunye nokufakela.

Xa sithatha umbhobho wesinyithi othambileyo we-DINSEN K9 (ubude obuqhelekileyo obuziimitha ezi-6) njengomzekelo, ubunzima bethiyori bulandelayo:

• DN100: Malunga ne-15.1 kg/m → 95 kg ngombhobho ngamnye
• DN200: Malunga ne-30.6 kg/m → 194 kg ngombhobho ngamnye
• I-DN300: Malunga ne-50.8 kg/m → 323 kg ngombhobho ngamnye
• DN500: Malunga ne-104.3 kg/m → 669 kg ngombhobho ngamnye
• DN800: Malunga ne-215.2 kg/m → 1394 kg ngombhobho ngamnye

Ubunzima bokwenyani bunokwahluka kancinci ngenxa yezinto ezinje ngobukhulu be-zinc coating kunye ne-inner cement mortar lining. I-DINSEN inokubonelela ngamaphepha okubala ubunzima achanekileyo ukuze kucwangciswe uhlahlo-lwabiwo mali lweprojekthi kunye nocwangciso lwezothutho.

III. Uxinzelelo olusebenzayo lweDuctile Iron Pipe

Umbhobho wesinyithi oxutyiweyo unamandla aphezulu okuxinana kunye namandla okuxinana ajikelezayo. Umbhobho wesinyithi oxutyiweyo oqhelekileyo we-K9 udla ngokuba noxinzelelo olusebenzayo lwe-16 bar (1.6 MPa), ngelixa amanqanaba aphezulu obukhulu bodonga (afana ne-K12) afanelekile kusetyenziso loxinzelelo lwe-25 bar okanye ne-40 bar.

Iipayipi zesinyithi ze-DINSEN ezenziwe nge-ductile zenziwe ngokungqongqo ngokwemigangatho ye-ISO 2531. Ipayipi nganye ivavanywa nge-hydrostatic ngaphambi kokuba iphume kumzi-mveliso ukuqinisekisa ukuba ukhuseleko luphezulu ngokuphindwe ka-1.5 kunoxinzelelo lokusebenza loyilo, nto leyo eyenza ukuba zifaneleke ngokukodwa ukuhanjiswa kwamanzi kumgama omde, iipayipi zokuphakamisa izitishi zokumpompa, kunye neepayipi zoshishino ezinoxinzelelo oluphezulu.

IV. I-Zinc Coating yoKhuseleko lokuGqwala

Indima Yokugquma I-Zinc kwiMibhobho ye-Ductile Iron Enye yezona ndlela zibalulekileyo zokukhusela imibhobho egqunyiweyo kukugquma i-zinc kwimibhobho ye-ductile iron. Ukugquma i-zinc akuboneleli nje kuphela ngokhuseleko lwe-cathodic kodwa kukwadala inkqubo yokulwa nokugqwala edibeneyo enepeyinti yangaphandle okanye i-polyethylene sheathing.

Iipayipi zentsimbi ezithambileyo zeDINSEN ziza ngokwesiqhelo kunye ne-≥200 g/m² ye-zinc coating (ngokwemigangatho ye-ISO 8179), egqunywe yi-asphalt ebomvu ye-epoxy okanye i-polyurethane finishing layer, nto leyo ephucula kakhulu ukumelana nokugqwala kunye nobomi bayo. Kwimihlaba egqwalisayo okanye kwiindawo ezinokumelana okuphezulu, i-zinc coating eyongezelelweyo + ifilimu ye-PE okanye i-polyurethane coating epheleleyo iyafumaneka, enobomi benkonzo obuyilelweyo beminyaka engama-50-100.

V. Kutheni Ukhetha Iipayipi Zesinyithi Ezithambileyo zeDINSEN?

Njengomthengisi weepayipi zesinyithi ezithambileyo, iDINSEN inikezela uluhlu olupheleleyo lweenkcukacha ukusuka kwi-DN80 ukuya kwi-DN2000, exhasa ubukhulu beendonga ezahlukeneyo ezifana ne-K8, K9, K10, kunye ne-K12, kwaye inokwenza ngokwezifiso ubude, ii-linings zangaphakathi (isamente mortar/epoxy resin), kunye nezisombululo zokukhusela ukugqwala kwangaphandle ukuhlangabezana neemfuno zabathengi.

Zonke iipayipi zentsimbi ezithambileyo ziqinisekisiwe yi-ISO 2531 / EN 545. Iitafile ezipheleleyo zobunzima, ubungakanani, uxinzelelo lokusebenza, kunye neeparamitha zokugquma ze-zinc ziyafumaneka. Iinkonzo zokupakisha kwamanye amazwe kunye neenkonzo zothutho oluhlala ixesha elinye ziyaxhaswa.

Ukuze ufumane iinkcukacha ezithe vetshe malunga nobungakanani kunye nobukhulu beetafile zokukhetha okanye izixhobo zokubala ubunzima, nceda undwendwele i-I-DINSENokanye uqhagamshelane neqela lokuthengisa lobuchwephesha ngokuthe ngqo.
