Ipayipi le-GI Ipayipi Lensimbi Elikhandiwe Ishubhu Elivunyiwe Lokubamba Uhlaka Lokushisa
Ipayipi elishisayo lokucwilisa
Amapayipi anamathangi asetshenziswa kakhulu kwezokwakha, ubunjiniyela bakamasipala, ukuhlinzekwa kwamanzi, uphethiloli, imboni yamakhemikhali neminye imikhakha. Emkhakheni wokwakha, amapayipi anamathani avame ukusetshenziswa emapayipini okuhambisa amanzi, amapayipi e-HVAC, ama-scaffolding, njll. Ebunjiniyela bakamasipala, amapayipi anamathani asetshenziswa ekunikezeni amanzi kanye namapayipi okukhipha amanzi, ama- guardrails ebhuloho, njll. Ezimbonini ze-petroleum ne-chemical industry. , amapayipi anezinsimbi asetshenziselwa ukuthutha uwoyela, igesi yemvelo neminye imithombo yezindaba.
Inzuzo yeIpayipi lensimbi eliyindilinga elivundisiweakukhona nje ukumelana nokugqwala kwayo, kodwa futhi indawo yayo ebushelelezi, ukubukeka kwayo okuhle, ukucubungula okulula, nezindleko eziphansi. Kodwa-ke, kufanele kuqashelwe ukuthi amapayipi ama-galvanized nawo adinga ukuhlolwa nokugcinwa njalo ngesikhathi sokusetshenziswa ukuze kuqinisekiswe ubuqotho bongqimba lwawo oluphikisana nokugqwala.
Izici
Ipayipi eliphehliwe linezici eziningi eziphawulekayo ezenza idume ngezinhlelo zokusebenza ezihlukahlukene zezimboni nezokwakha. Okokuqala, esinye sezici ezinkulu zepayipi likathayela ukumelana nokugqwala kwalo okuhle kakhulu. Ngenxa yokuthi indawo engaphezulu yamapayipi kathayela imbozwe ungqimba lwezinc, lolu ungqimba oluyisivikelo lungamelana ngokuphumelelayo nokugqwala ezindaweni eziningi, okuhlanganisa isimo sezulu esiswakeme, imithombo yamakhemikhali, nezinto ezibolayo emhlabathini. Lokhu kunikeza amapayipi akathayela ukuqina okuhle kakhulu endaweni enomswakama, egqwalayo njengamapayipi okuhambisa amanzi namapayipi amakhemikhali.
Okwesibili, ipayipi likathayela linamandla amakhulu nokumelana nokugqoka. Amandla ombhobho wensimbi ngokwawo ahlanganiswe nokuvikelwa kwesendlalelo se-zinc kwenza ipayipi le-galvanized likwazi ukumelana nokucindezela okukhulu nomthelela futhi lifaneleka ezindaweni ezihlukahlukene zobunjiniyela. Ngaphezu kwalokho, ubuso bamapayipi othayela bushelelezi futhi akulula ukugqwala, ngakho bunokumelana okuhle kokugqoka futhi bungakwazi ukugcina ukubukeka okuhle nokusebenza isikhathi eside.
Ngaphezu kwalokho, ipayipi likathayela linezakhiwo ezinhle zokucubungula futhi kulula ukusika, ukulishisela nokulifaka. Lokhu kwenza ukuba kusetshenziswe kahle kakhulu amapayipi anothayela kumaphrojekthi wokwakha, kuncishiswe isikhathi sokucubungula nokufakwa kanye nezindleko.
Ngokuvamile, amapayipi amapayipi asephenduke into ebalulekile yamapayipi emkhakheni wezimboni nezokwakha ngenxa yokumelana nokugqwala kwawo, amandla aphezulu, ukumelana nokugqoka kanye nezakhiwo ezinhle zokucubungula. Izakhiwo zayo eziningi ezinhle kakhulu zenza amapayipi anamathani adlale indima ebalulekile ezindaweni namaphrojekthi ahlukahlukene anokhahlo.
Isicelo
Amapayipi ensimbi asetshenziswa kabanzi ezimbonini eziningi:
1. Amapayipi namapayipi egesi: Amapayipi ensimbi asetshenziswa kakhulu kumapayipi nasezinhlelweni zamapayipi egesi. Ziyakwazi ukumelana nokugqwala, ziqinisekisa ukuphepha nokuphila isikhathi eside kohlelo lwamapayipi. Imigqa yamapayipi kanye negesi esebenzisa ipayipi lensimbi ethathiwe kulula ukuyifaka nokuyinakekela.
2. Uhlelo lokunisela: Amapayipi ensimbi anezinsimbi nawo asetshenziswa embonini yokunisela. Ziyakwazi ukumelana nokugqwala futhi ziyakwazi ukumelana nokuchayeka kumakhemikhali anonya atholakala kumanyolo neminye imikhiqizo yezolimo. Lawa mapayipi asetshenziselwa ukuthutha amanzi emapulazini ngoba angakwazi ukumelana nemiphumela yenhlabathi, umswakama nezinye izakhi zemvelo.
3. Izicelo zezimboni: Amapayipi ensimbi anamapayipi avame ukusetshenziswa emisebenzini ehlukahlukene yezimboni. Asetshenziselwa ukwakha izakhiwo, amabhuloho nezinye izakhiwo. Lawa mapayipi asetshenziselwa ukwenza izingxenye zezimoto ezifana nesistimu yokukhipha umoya, izishintshisi zokushisa kanye nezingxenye zenjini.
4. Imboni Kawoyela Negesi: Imboni kawoyela negesi ithembele kakhulu emapayipini ensimbi ayizinsimbi njengoba ekwazi ukumelana nokugqwala futhi ekwazi ukumelana namazinga okushisa aphakeme nezingcindezi. Lawa mapayipi asetshenziswa ekuhloleni, ekumbiweni nasekuthuthweni kwemikhiqizo kawoyela negesi.
5. Ukufakwa kwesakhiwo: Amapayipi ensimbi angasetshenziswa futhi ezinhlobonhlobo zezinhlelo zokusebenza zesakhiwo. Ikwazi ukumelana nemithwalo ephakeme kanye nezingcindezi, lawa mapayipi asetshenziselwa ukwakhiwa kwamabhuloho, izakhiwo nezinye izakhiwo. Zibuye zisetshenziselwe ukwenza i-scaffolding nezinye izakhiwo zesikhashana.

Imininingwane
Ungqimba lwezinc lwepayipi likathayela lubhekisela kungqimba oluvikelayo lwezinc olumboze ubuso balo. Lolu ngqimba oluvikelayo lwe-zinc lwakhiwa ngenqubo yokufaka ama-galvanizing ediphu eshisayo, ecwilisa ipayipi lensimbi ku-zinc encibilikisiwe ukuze ubuso balo bumbozwe ngokulinganayo ungqimba lwezinc. Ukwakhiwa kwalolu ungqimba lwezinc kunikeza ipayipi eliphehla ugesi ukumelana nokugqwala okuhle kakhulu. Ungqimba lwezinki lumelana ngempumelelo nokugqwala ezindaweni eziningi, okuhlanganisa isimo sezulu esiswakeme, imithombo yamakhemikhali kanye nezinto ezibolayo emhlabathini. Ngakho-ke, amapayipi othayela anokuqina okuhle kakhulu endaweni enomswakama kanye negqwala njengamapayipi okuhambisa amanzi namapayipi amakhemikhali.
Ukwakhiwa kwesendlalelo se-zinc kunikeza ipayipi elinamandla amandla aphezulu nokumelana nokugqoka. Amandla ombhobho wensimbi ngokwawo ahlanganiswe nokuvikelwa kwesendlalelo se-zinc kwenza ipayipi le-galvanized likwazi ukumelana nokucindezela okukhulu nomthelela futhi lifaneleka ezindaweni ezihlukahlukene zobunjiniyela. Ngaphezu kwalokho, ubuso obushelelezi bengqimba ye-zinc akulula ukugqwala, kunokumelana okuhle kokugqoka, futhi kungagcina ukubukeka okuhle nokusebenza isikhathi eside.
Ngokuvamile, ungqimba lwezinki lwamapayipi akathayela luyisihluthulelo sokumelana nokugqwala kwawo, amandla aphezulu, nokumelana nokugqoka, okwenza amapayipi anathayela abe impahla yamapayipi abalulekile ezimbonini nasezindaweni zokwakha. Izakhiwo zayo eziningi ezinhle kakhulu zenza amapayipi anamathani adlale indima ebalulekile ezindaweni namaphrojekthi ahlukahlukene anokhahlo.
Ukuthuthwa nokupakishwa kwamapayipi kathayela kuyizixhumanisi ezibalulekile zokuqinisekisa ukuthi imikhiqizo ifika lapho iya khona ngokuphepha futhi igcine ikhwalithi yomkhiqizo. Ngesikhathi sokuthutha, amapayipi anamathani ngokuvamile athuthwa kusetshenziswa izinto zokuhamba ezichwepheshile, njengamaloli noma iziqukathi, ukuze kuqinisekiswe ukuhamba okuphephile. Ngesikhathi sokulayisha nokukhipha, ukungqubuzana nokukhishwa kufanele kugwenywe ukuze kugwenywe ukulimaza ungqimba lwama-galvanized ebusweni bepayipi.
Ngokuphathelene nokupakisha, izinyathelo zokuzivikela ezifanele, njengama-pallets enziwe ngokhuni, amafilimu epulasitiki, izinto zokulwa nokushayisana, njll., ngokuvamile zisetshenziselwa ukuvimbela amapayipi othayela ukuthi angalimali ngesikhathi sokuthutha. Ukwengeza, ukupakishwa kufanele futhi kuhambisane nezindinganiso nemithethonqubo efanele ukuze kuqinisekiswe ukuthi ulwazi lomkhiqizo lubonakala ngokucacile, njengemodeli yomkhiqizo, imininingwane ecacisiwe, inani, njll., futhi kufanele lubonise izinyathelo zokusingatha kanye nezinyathelo zokuvikela umswakama kanye nelanga.
Ezokuthutha ezihamba amabanga amade, ikakhulukazi ezokuthutha olwandle, ukupakishwa kwamapayipi anezinsimbi nakho kudingeka kubhekwe izindlela zokulwa nokugqwala. Ama-ejenti angangenisi umswakama noma ama-anti-rust ngokuvamile ayafakwa ephaketheni ukuze kuvikelwe amapayipi anamathani ekugqwaleni ezindaweni ezinomswakama.
Ngokuvamile, ukuthuthwa nokupakishwa kwamapayipi athathiwe kudinga ukucutshungulwa ngokuphelele izici zomkhiqizo kanye nemvelo yokuthutha, futhi kwamukele izinto zokupakisha ezifanele kanye nezinyathelo zokuzivikela ukuze kuqinisekiswe ukuthi umkhiqizo ufinyelela lapho uya khona ngokuphepha ngesikhathi sokuthutha futhi ugcine ikhwalithi yomkhiqizo omuhle.
