uchwepheshe wepayipi

Iminyaka eyi-15 Yokukhiqiza

Isingeniso sepayipi lokuhambisa amanzi e-PE

I-polyethylene resin njengokuqukethwe okuyinhloko okuluhlaza okwenziwe, ngemuva kwephayiphu yokubumba amanzi e-polyethylene ebizwa nge-PE water pipe.

Imishini yokukhiqiza ipayipi lamanzi e-PE?

Umugqa wokukhiqiza waseJalimane Como. Le mishini yenziwa ngobuchwepheshe obuthuthuke kakhulu emhlabeni, ngesibalo esisheshayo se-extrusion, ukuncibilika okulingene, ukusika okuzenzakalelayo, ukulawula kwe-PLC kwenqubo yokukhiqiza yokusebenza okuthuthukile.

Ipayipi le-PE ekusetshenzisweni kwezinga?

Izinga elijwayelekile le-GB / T 13663-2000.

Uyini umbala ongaphezulu wepayipi lamanzi le-PE

Umbala ongaphezulu ikakhulukazi umnyama, kanti abambalwa badinga okumhlophe. Ishubhu elimnyama linomugqa oluhlaza okwesibhakabhaka ogqamile ebusweni balo.

Yini imininingwane yomkhiqizo wepayipi lamanzi le-PE?

PE80

Ukucindezela okuzenzakalelayo: 0.4mpa, 0.8mpa, 1.0mpa, 1.25Mpa;

Ububanzi engaphandle: φ25 ~ φ1600mm.

PE100

Ingcindezi Okuzisholo: 0.6mpa, 0.8mpa, 1.0mpa, 1.25Mpa, 1.6mpa;

Ububanzi engaphandle: φ32 ~ φ1800mm.

Izici zomkhiqizo wepayipi lamanzi we-PE?

(1) Amandla aphakeme, ukumelana okuhle nokucindezela kwemvelo, ukumelana okuhle okungangena.

(2) Ubulukhuni obuhle nokuzivumelanisa nezimo, ukuzivumelanisa nezimo okuqinile kwisisekelo esingalingani nokuhlukaniswa, futhi kungamelana nokuzamazama komhlaba, izivunguvungu nezinye izindawo ezinzima.

(3) Inokumelana okuhle kwesimo sezulu (kufaka phakathi ukumelana ne-UV) nokuzinza okushisayo okuhlala isikhathi eside.

(4) Corrosion ukumelana, asikho isidingo sokwenza ukwelashwa anti-ukugqwala, ukuphila isikhathi eside.

(5) udonga lwangaphakathi lubushelelezi, ukumelana nokugeleza kwamanzi kuncane, umthamo wokujikeleza mkhulu, futhi izindleko zokwakha ziyagcinwa.

(6) Ukugqoka okuhle ukumelana nokugqoka ukumelana.

(7) Ukumelana nomthelela wokushisa okuphansi kuhle, kungaba sebangeni lokushisa kwe - 20-40 ℃ ukusetshenziswa okuphephile, ukwakhiwa kwasebusika akuthinteki.

(8) Ukuncibilika kukagesi (noma ukuncibilika okushisayo) ukuxhumana kulula futhi kunokwethenjelwa, ukwakhiwa nokugcinwa okulula (lapho amanzi enganqanyulwa khona).

(9) Ifaneleke ngokuphelele izindlela zendabuko zokwakhiwa kokumbiwa kanye nobuchwepheshe obusha obungenamjelo njengokubhoboza ipayipi, ukubhola okuqondisayo, ulwelwesi, ukuqhekeka kwamapayipi nokucwila ngaphansi kwamanzi.

(10) Izinto zokusetshenziswa ze-Polyethylene ziqukethe kuphela ikhabhoni, i-hydrogen izakhi ezimbili, engenabungozi emzimbeni womuntu.

(11) Ukusetshenziswa kobuchwepheshe obuphambili be-nano antibacterial, okuvimbela ngempumelelo ukukhula kwe-algae, amabhaktheriya nesikhunta, luhlaza, okunempilo, nokuvikelwa kwemvelo kwepayipi lamanzi okuphuza

Izici zomkhiqizo:

1. Ukuxhumeka okunokwethenjelwa: Amapayipi wokuhambisa amanzi wePolyethylene axhunywe ngokuncibilika okushisayo kagesi; Flange uxhumano namanye amapayipi, elula futhi esheshayo.

Okubili, ukumelana nomthelela wokushisa okuphansi kuhle: izinga lokushisa eliphansi lokufakwa kwe-polyethylene liphansi kakhulu, lingasetshenziswa ngokuphepha ebangeni lokushisa lika -35 ℃ -60 ℃. Ekwakhiweni kwasebusika, ipayipi ngeke liqhekeke ngenxa yokumelana okuhle kwento.

Okwesithathu, ukumelana nokugqwala kwamakhemikhali okuhle kakhulu: Ipayipi le-HDPE lingamelana nokugqwala kwezinhlobonhlobo zemidiya yamakhemikhali, ukuba khona kwamakhemikhali enhlabathini ngeke kuveze noma yikuphi ukonakala kwepayipi.

Okune, ukumelana nokuguga, impilo ende yokusebenza: ipayipi le-polyethylene eliqukethe ukusatshalaliswa okufanayo kwe-carbon black lingagcinwa ngaphandle noma lisetshenziswe iminyaka engama-50, ngeke lonakaliswe yimisebe ye-ultraviolet.

Okuhlanu, okuhle okuhle: Ukuguquguquka kwephayiphu le-HDPE kwenza kube lula ukugoba, ubunjiniyela bungadlula izithiyo ngokushintsha indlela ipayipi, ezikhathini eziningi, ukuguquguquka kwepayipi kunganciphisa inani lokufakwa kwamapayipi futhi kunciphise izindleko zokufaka.

Ukumelana nokugeleza okuphansi: Ipayipi le-HDPE linobuso obushelelezi bangaphakathi kanye ne-coefficient yeManning engu-0.009. Ubuso obushelelayo nezimpawu ezinganamatheli zamapayipi e-HDPE zivumela umthamo wokulethwa ophakeme kuneshubhu ejwayelekile, ngenkathi kunciphisa ukulahleka kwengcindezi nokusetshenziswa kwamanzi.

Isikhombisa, ukuphatha okulula: ipayipi le-HDPE lilula kunepayipi likakhonkolo, ipayipi lashukumisa nensimbi yensimbi, kulula ukuphatha nokufaka, izindleko zokufaka iphrojekthi zinciphile kakhulu.

Izindlela eziyisishiyagalombili, zokwakha ezahlukahlukene: ipayipi lokuhambisa amanzi le-HDPE, ngaphezu kwendlela yendabuko yokumba, kepha futhi ingasebenzisa ubuchwepheshe obusha obungenanjongo njengokufaka ipayipi, ukubhoboza okuqondile, ulwelwesi, ukwakhiwa kwamapayipi, ngakho-ke uhlelo lokusebenza lwepayipi le-HDPE kabanzi.
