Omaka bomkhiqizo

Yethula:

Amapayipi amanzi amakhulu ngamaqhawe angaculwa ahlinzeka ngamanzi abalulekile emiphakathini yethu.Lawa manethiwekhi angaphansi komhlaba adlala indima ebalulekile ekuqinisekiseni ukugeleza kwamanzi okungaphazamiseki emakhaya ethu, amabhizinisi nezimboni.Njengoba isidingo siqhubeka sikhula, kubalulekile ukusebenzisa izinto ezisebenza kahle neziqinile kulawa mapayipi.Enye yezinto ezinakwa kakhulu ipayipi elishiselwe elivunguzayo.Kule bhulogi, sizocubungula ukubaluleka kwamapayipi ashiselwe ayindilinga kumapayipi amakhulu okuhambisa amanzi futhi sixoxe ngezinzuzo zawo.

Funda ngamapayipi ashiselwe ku-spiral:

Ngaphambi kokuthi singene ezinzuzweni zeamapayipi ashiselwe asontekile, ake siqale siqonde umqondo wamapayipi ashiselwe athandelene.Ngokungafani namapayipi endabuko ashiselwe aqondile, amapayipi ashiselwe asontekile enziwa ngokugoqa nokushisela amakhoyili ensimbi ngendlela ezungelezayo.Le nqubo yokukhiqiza eyingqayizivele inika ipayipi amandla angokwemvelo, okwenza kube ekahle ekusebenzeni okungaphansi komhlaba njengamapayipi amanzi.

Izinzuzo zamapayipi ashiselwe ku-spiral kumapayipi amakhulu okuhambisa amanzi:

1. Amandla anda nokuqina:

Ubuchwepheshe be-spiral welding obusetshenziswa kula mapayipi budala isakhiwo esiqhubekayo, esingenamthungo esinamandla amakhulu nokumelana nokucindezela okuphezulu kwangaphakathi nangaphandle.Ukwengeza, ama-spiral seam aqinile aqinisa ubuqotho bepayipi, enciphisa ingozi yokuvuza noma ukuqhuma.Lokhu kuqina kuqinisekisa impilo ende yesevisi yamapayipi amanzi akho, kunciphisa ukukhanda kanye nezindleko zokuwashintsha.

2. Ukumelana nokugqwala:

Imigqa yamanzi eyinhloko ibhekene nezimo ezihlukahlukene zemvelo, kuhlanganise nomswakama, amakhemikhali nomhlabathi.Amapayipi ashiselwe ku-Spiral ngokuvamile akhiqizwa kusetshenziswa izinto ezimelana nokugqwala njengensimbi engagqwali, eqinisekisa ukuvikeleka okuhle kakhulu kokugqwala, ukuguguleka, nezinye izinhlobo zokugqwala.Lokhu kumelana kwandisa impilo yamapayipi, kuvimbela ukuwohloka nokugcina izinga lamanzi.

3. Ukusebenza kahle kwezindleko:

Ukutshala imali kumapayipi ashiselwe okuvunguza ukuzeipayipi lamanzi elikhuluskungaba inketho engabizi ngokuhamba kwesikhathi.Isakhiwo sayo esiqinile nokumelana nokugqwala kunciphisa imvamisa yokulungiswa nokushintshwa, ngaleyo ndlela konga izindleko ezibalulekile zokunakekela.Ukwengeza, kulula ukuzifaka, zilula, futhi zinciphisa isidingo sezisekelo ezengeziwe, okwenza kube inketho elula futhi engabizi kumaphrojekthi amakhulu amapayipi.

4. Ukuguquguquka nokuguquguquka:

I-spiral welded pipe inikeza izinga eliphezulu lokuguquguquka nokuguquguquka ekusebenzeni kwayo.Zingakhiqizwa ngamadayimitha ahlukene, ubude nobukhulu, okuzivumela ukuba zenziwe ngokwezifiso ukuze zihlangabezane nezidingo ezithile zephrojekthi.Lokhu kuvumelana nezimo kuzivumela ukuba zikwazi ukuzivumelanisa nezimo ezihlukahlukene kanye nezimo ezihlukahlukene zomhlabathi, okubenza babe ukukhetha okuhle kakhulu kwamapayipi amakhulu okuhambisa amanzi ezindaweni zasemadolobheni nasezindaweni zasemakhaya.

5. Ukusimama kwemvelo:

Ngaphezu kwezinzuzo zabo zokusebenza, amapayipi ashiselwe okuvunguzayo nawo enza umnikelo omuhle ekusimameni kwemvelo.Izinto ezisetshenziswa ekwakhiweni kwayo ziyakwazi ukugaywa kabusha, zinciphisa i-carbon footprint isiyonke.Ukwengeza, idizayini yayo engenamthungo inciphisa ukulahleka kwamanzi ngenxa yokuvuza, ngaleyo ndlela ivikele lo mthombo obalulekile.

a.Indlela ye-deoxidation ikhethwe kanje:

FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al).

b.Inani eliphakeme kakhulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N.Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola.

Ekuphetheni:

Ukuqinisekisa ukusebenza kahle kanye nokuqina kwamapayipi akho amakhulu amanzi kubalulekile ekuqinisekiseni ukutholakala kwamanzi okuthembekile.Ukusetshenziswa kwamapayipi ashiselwe Kuvunguza kuleziipayipi imigqainikeza izinzuzo eziningi, okuhlanganisa amandla anda, ukumelana nokugqwala, ukuphumelela kwezindleko, ukuguquguquka nokusimama kwemvelo.Njengoba sisebenzela ukwakha ingqalasizinda yamanzi eqinile futhi esebenza kahle, ukutshala imali kubuchwepheshe obuthuthukisiwe obufana nepayipi elishiselwe elizungezayo kubalulekile.
