1. Iyini ingcindezi yepayipi le-PE?

Ngokwezidingo ezijwayelekile zikazwelonke ze-GB/T13663-2000, ingcindezi yeAmapayipi e-PEingahlukaniswa ngamaleveli ayisithupha: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, kanye ne-1.6MPa. Ngakho isho ukuthini le datha? Kulula kakhulu: Isibonelo, i-1.0 MPa, okusho ukuthi ingcindezi evamile yokusebenza yalolu hlobo lweI-Hdpe Fittingsingu-1.0 MPa, okuyilokho esivame ukukubiza ngokuthi umfutho we-10 kg. Yiqiniso, ekuhlolweni kwengcindezi yangaphambilini, ngokwezidingo zamazinga kazwelonke, idinga ukucindezela izikhathi ezingu-1.5. Gcina ingcindezi amahora angu-24, okungukuthi, ukuhlolwa kwenziwa ngomfutho wamanzi we-15 kg.

2. Iyini inani le-SDR lepayipi le-PE?

Inani le-SDR, elaziwa nangokuthi isilinganiso sosayizi ojwayelekile, isilinganiso sobubanzi obungaphandle kuya kugqinsi lodonga. Ngokuvamile sisebenzisa inani le-SDR ukumela isilinganiso somfutho wekhilogremu. Amanani ahambisanayo e-SDR wamazinga ayisithupha we-0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, kanye ne-1.6MPa yilawa: SDR33/SDR26/SDR21/SDR17/SDR13.6/SDR11.

Okwesithathu, umbuzo wobubanzi bepayipi le-PE

Ngokuvamile, amapayipi e-PE anobubanzi obungu-20mm-1200mm. I-diameter esikhuluma ngayo lapha empeleni ibhekisela kububanzi obungaphandle. Isibonelo, ipayipi le-PE le-De200 1.0MPa empeleni liyi-PE enobubanzi obungaphandle obungu-200, ukucindezela kwe-10 kg, nobukhulu bodonga obungu-11.9 mm. iphayiphi.

Okwesine, indlela yokubala yesisindo semitha yepayipi le-PE

Lapho abasebenzisi abaningi beza ukuzobuza mayelana nenani leI-Hdpe Pipe Fittings, abanye bazobuza ukuthi yimalini ikhilogremu, sidinga ukusebenzisa ucezu olulodwa lwedatha lapha-imitha isisindo.

Sizobhala amafomula athile okubala isisindo semitha samapayipi e-PE. Abangane abaswele bayobakhumbula. Kuzoba usizo emsebenzini wesikhathi esizayo:

Isisindo semitha (kg/m)=(ukujiya kodonga lwangaphandle)*ukujiya kodonga*3.14*1.05/1000

Nokho, yilokho kuphela okuqukethwe kwanamuhla. Ukuze uthole ulwazi olwengeziwe mayelana namapayipi e-PE, sicela uqhubeke nokusinaka. Joyina izandla neShentong ukuze uwine imakethe, wamukelekile ukubuza.
