Ipayipi lokuvikela ikhebula lamandla le-MPP

Njengohlobo olusha lwepayipi lezinto ze-polymer, ipayipi lokuvikela ikhebula le-MPP linokumelana okuhle kakhulu nokugqwala, ukumelana nokuguga, ukumelana nokushayisana, kanye nokumelana ne-UV. Ngakho-ke, ezindaweni zemvelo ezahlukahlukene ezinzima kanye nezimo zobunjiniyela, ipayipi lokuvikela ikhebula le-MPP lingagcina ukusebenza okuhle, linikeze ukuvikelwa kwesikhathi eside nokuzinzile kwezintambo.

1. Isisindo esincane, kulula ukuyithutha nokuyifaka ukwakha; ukuguquguquka okuhle, okwenza kube lula futhi konge imali uma kubekwa. Ingaphinde isetshenziswe, ngokuhambisana nezidingo zokuvikela imvelo; lapho ipayipi ligoba, ukucindezeleka engxenyeni yokugoba kungakhululeka ngokushesha, akukho "ukubuyela emuva" okwenzekayo, kulula ukusebenza ekwakheni;

2. Ukulahlekelwa okuncane kokungqubuzana epayipini, amandla okudlulisa uketshezi epayipini makhulu ngo-10% kunowepayipi le-PE-X elinobubanzi obufanayo; ukusebenza kokumelana nomthelela kuphindwe kabili kunokwezinto zepayipi le-PE-X;

3. Izinga lokushisa eliphansi lokuphuka kanye nokusebenza kahle kwezinga lokushisa eliphansi lezinto zepayipi kwenza kube nokwenzeka ukwakhiwa ebusika ngaphansi kwezimo zokushisa eziphansi futhi akudingeki ukushisa kusengaphambili lapho kugoba ipayipi, okungaxazulula ukulahlekelwa kwezomnotho okubangelwa ukungakwazi ukwakha enyakatho yeShayina ngenxa yokushisa okuphansi ebusika. Irediyasi encane yokugoba iphindwe kahlanu kunobubanzi bangaphandle bepayipi;

4. Ukumelana okuhle nokugqwala kwamakhemikhali, akukho ukugqwala, impilo yenkonzo ende.

5. Ukumelana okuhle kokuqhekeka, ukuqhekeka kwepayipi le-PE-RT kuyashintsha ngokushintsha kwezinga lokushisa, i-PE-RT ayidingi ipuleti elixhunywe nge-cross-linked ngenxa yezinto zokusetshenziswa ezikhethekile, uma selakhiwe ngemva kokukhiqizwa, ukuqhekeka kuhlala unomphela;

6. Azikho izithasiselo ezinobuthi ezingezwayo enqubweni yokukhiqizwa kwezinto zamapayipi, udonga lwangaphakathi olubushelelezi, akukho kukhula, akukho ukukhula kwamagciwane, kungasetshenziswa ngokuphephile ekudlulisweni kwamanzi okuphuza nakwezinye izinkambu;

7. Ukusebenza kahle kokushabalalisa ukushisa, ukuhanjiswa kokushisa kungu-0.4W/(m • K), kungonga amandla amaningi ekusetshenzisweni kokushisa, ngakho-ke i-PE-RT inganikeza ukusebenza okugcwele ezicini zayo ezinhle kakhulu emkhakheni wokushisa;

8. Ukushibilika;

Ipayipi lokuvikela ikhebula le-MPP lihlanganisa ukuvikelwa kwemvelo, impilo, ukuvala, ukulwa nokugqwala, ukuvikela ukushaqeka, ikhwalithi ephezulu, intengo ephansi, ukwakhiwa okulula nezinye izinzuzo. Linezinzuzo ezinhle kwezomnotho nakwezenhlalo emkhakheni wamandla kagesi, futhi linethuba elikhulu lokusetshenziswa.

Isifinyezo semininingwane namamodeli epayipi lokuvikela ikhebula lamandla le-MPP

Imininingwane yayo kanye namamodeli ahlukaniswa kakhulu ngobubanzi bangaphandle, ukujiya kodonga kanye nobude, okulandelayo ukuhlukaniswa okuningiliziwe kwemininingwane evamile:

1. Inhlanganisela yobubanzi bangaphandle kanye nobukhulu bodonga

DN90mm
Ubukhulu bodonga: 5mm, 6mm

DN110mm
Ubukhulu bodonga: 6mm, 7mm, 8mm, 9mm, 10mm

DN160mm
Ubukhulu bodonga: 7mm, 8mm, 9mm, 10mm, 11mm, 12mm

DN180mm
Ubukhulu bodonga: 10mm, 12mm, 15mm

DN200mm
Ubukhulu bodonga: 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm

DN225mm
Ubukhulu bodonga: 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 18mm

DN250mm
Ubukhulu bodonga: 13mm, 14mm, 15mm, 16mm, 17mm, 20mm

2. Ukucaciswa kobude

Ubude bepayipi elilodwa elivamile bungamamitha ayi-6, amamitha ayi-9, amamitha ayi-12.

3. Izimo zokuhlukaniswa kanye nokusetshenziswa

Uhlobo lokumba: lufanelekela amaphrojekthi okubeka izintambo avamile.

Uhlobo olungavubukuli (ipayipi elifakwayo/elidonswayo): elisetshenziselwa ukuvikela izintambo ezindaweni ezikhethekile njengemigwaqo, izitimela kanye nogu lomfula ngaphandle komonakalo omkhulu emhlabathini.

Iziphakamiso zokukhetha:

Ububanzi obuncane (njenge-DN90mm, DN110mm) busetshenziswa kakhulu ekubekeni ikhebula elijwayelekile, ukujiya kodonga kuncane kakhulu;

Ububanzi obukhulu (njenge-DN200mm nangaphezulu) bufanelekela izintambo zikagesi eziphezulu kakhulu noma izindawo eziyinkimbinkimbi (njengokuwela imigwaqo), futhi ungqimba olukhulu lodonga luyadingeka ukuze kuthuthukiswe amandla okuthwala ingcindezi.

4. Imodi yokuxhumana

Imodi yokuxhuma yepayipi lokuvikela ikhebula le-MPP nayo iyingxenye yemininingwane yayo. Izindlela zokuxhuma ezivamile zifaka phakathi uxhumano lwesokhethi, uxhumano lwe-hot fusion, uxhumano lwe-electric fusion, njll. Izindlela zokuxhuma ezahlukene zifanelekile ezimweni ezahlukene zohlelo lokusebenza kanye nezidingo zobunjiniyela. Ukukhetha imodi yokuxhuma efanele kungaqinisekisa ukuphepha nokuthembeka kwepayipi lekhebula.

Uma ukhetha amapayipi okuvikela ikhebula le-MPP, kubalulekile ukucabangela izidingo ezithile zephrojekthi, izimo zokwakha, kanye nemininingwane nezici zamakhebula, ukuqinisekisa ukuthi zonke izici ziyahambisana. Ngaphezu kwalokho, ukuqinisekisa ikhwalithi nokuphepha kwamapayipi ekhebula, kubalulekile ukukhetha abakhiqizi abadumile kanye nemikhiqizo esezingeni eliphezulu. Ngesikhathi sokwakha, kubalulekile ukulandela amazinga okwakha afanele kanye nezidingo zobuchwepheshe ukuqinisekisa ikhwalithi yokufaka kanye nokusebenza kahle kwamapayipi ekhebula.

Ngamafuphi, imininingwane yepayipi lokuvikela ikhebula le-MPP iyahlukahluka, futhi ukukhethwa kwemininingwane efanele kanye nemodi yokuxhuma kubalulekile ekuvikeleni ikhebula. Ekusetshenzisweni okungokoqobo, kubalulekile ukucabangela nokukhetha ngokwezimo ezithile ukuqinisekisa ukuphepha, ukuthembeka, ukonga kanye nokusebenza kahle kwepayipi lekhebula.
