Isiqeshana sensimbi enezimbobo Ipayipi le-PE Okokuphakela amanzi Isithombe esifakiwe

Ipayipi lensimbi elinezimbobo Ipayipi le-PE Ukuze uthole amanzi

Incazelo emfushane:

Perforated steel strip polyethylene ipayipi esiyinhlanganisela yimikhiqizo esikhundleni bendabuko steel ipayipi PVC amanzi okuphuza amapayipi, okuyinto engenawo nje umnotho omuhle, kodwa futhi inezinzuzo interface ezinzile futhi enokwethenjelwa, ukumelana nomthelela wezinto ezibonakalayo, ukumelana crack, ukumelana ukuguga, ukumelana nokugqwala. njalo njalo. Kwenziwe kusukela ku-100% yezinto zokusetshenziswa zepayipi lezintombi, ezinokuguquguquka okuhle kakhulu kuhlanganiswe namandla

Isicelo

Ipayipi elihlanganisiwe lensimbi elinezimbobo le-polyethylene lenziwe ngensimbi egoqelwe ebandayo kanye ne-thermoplastics njengezinto zokusetshenziswa, futhi amapayipi ensimbi anezindonga ezincane anezimbobo akhiwa i-argon arc butt welding noma i-plasma spiral welding asetshenziswa njengeziqinisi. Izendlalelo zangaphandle nezingaphakathi ziyi-thermoplastic ehlanganisiwe enezinhlangothi ezimbili. Uhlobo olusha lwepayipi lokucindezela eliyinhlanganisela, Ngenxa yokuthi ipayipi lensimbi elinezimbobo ezincane elinezindonga eziqinile ligoqwe nge-thermoplastic eqhubekayo, leli payipi eliyinhlanganisela aligcini nje ngokunqoba ukushiyeka okukhona kwamapayipi ensimbi namapayipi epulasitiki, kodwa futhi linokuqina kwamapayipi ensimbi nokugqwala. ukumelana namapayipi epulasitiki. Kuyisixazululo sezimboni ze-petroleum kanye namakhemikhali. Kuyipayipi elidingeka ngokuphuthumayo lamapayipi amakhulu naphakathi nendawo aqinile emkhakheni wemithi, ukudla, izimayini, igesi kanye neminye imikhakha. Kuphinde kube yimpumelelo yezinguquko kwezobuchwepheshe ukuxazulula ipayipi elikhulu lokwakha kanye nokuhlinzekwa kwamanzi kamasipala. Iwuhlobo olusha lwepayipi eliyinhlanganisela ku-21^stikhulu leminyaka.

Izici

Amandla aphezulu kanye nokunwetshwa komugqa okuphansi.
Ngenxa yokuqiniswa kohlaka lwensimbi, ipayipi eliyinhlanganisela yensimbi enezimbobo linamandla aphakeme, ukuqina okuphezulu kanye nokumelana nomthelela kunepayipi lepulasitiki. Ngesikhathi esifanayo, umphumela wokuvimbela wefreyimu yensimbi uphinde wenze ipayipi ye-perforated steel strip plastic composite ibe а umugqa ophansi ofana nowombhobho wensimbi. Ukunwetshwa kwe-coefficient kanye nokumelana ne-сгеер.

Ukugqwala nokumelana nokugqoka.
Izinto ze-polyethylene ezinobukhulu obuphezulu ezikhethelwe umugqa wensimbi onezimbobo ipayipi eliyinhlanganisela yepulasitiki iyi-crystalline non-polar polymer material enezakhiwo zamakhemikhali ezizinzile, ukumelana ne-asidi eminingi, usawoti we-alkali kanye nemidiya ye-organic, kanye nokugqwala kwe-electrochemical. Ukusebenza kokugaya kuphakeme izikhathi ezi-5 kunamapayipi ensimbi.

Imingcele Yezobuchwepheshe

Lo mkhiqizo usebenzisa i-polyethylene resin ekhethekile, futhi izakhiwo zayo zomzimba nezemishini zihlangabezana nezinga le-Ministry of Construction CJ/T181-2003 kanye nezinga lemboni yamakhemikhali HG/T3706-2014.

Qaphela: Ukucindezela okulinganiselwe kwepayipi elihlanganisiwe kuwukucindezela okukhulu okuvunyelwe ukuba ipayipi lihambise amanzi ku-20 ° С. Uma izinga lokushisa lishintsha, ingcindezi yokusebenza kufanele ilungiswe ngokuvumelana ne-coefficient yokucindezela kwezinga lokushisa kwezinto ezihlukahlukene. Inani lika-S: ibanga ukusuka kububanzi obungaphandle bokuqiniswa ukuya endaweni yangaphandle yepayipi.
