1. Yintoni uxinzelelo lwepayipi ye-PE?

Ngokweemfuno zomgangatho wesizwe we-GB/T13663-2000, uxinzelelo lweImibhobho ye-PEinokwahlulwa ibe ngamanqanaba amathandathu: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, kunye ne-1.6MPa. Ke ingaba le datha ithetha ntoni? Kulula kakhulu: Umzekelo, 1.0 MPa, nto leyo ethetha ukuba uxinzelelo oluqhelekileyo lokusebenza kolu hloboIzixhobo zeHDpeyi-1.0 MPa, nto leyo esihlala siyibiza ngokuba yi-10 kg yoxinzelelo. Ngokuqinisekileyo, kuvavanyo lwangaphambili loxinzelelo, ngokweemfuno zemigangatho yelizwe, kufuneka ibe uxinzelelo ngamaxesha e-1.5. Gcina uxinzelelo lweeyure ezingama-24, oko kukuthi, uvavanyo lwenziwa ngoxinzelelo lwamanzi lwe-15 kg.

2. Yintoni ixabiso le-SDR lombhobho we-PE?

Ixabiso le-SDR, ekwabizwa ngokuba yi-standard size ratio, ngumlinganiselo we-diameter yangaphandle ukuya kwi-wall wall. Siqhele ukusebenzisa ixabiso le-SDR ukumela umlinganiselo woxinzelelo lwekhilogram. Amaxabiso ahambelanayo e-SDR amanqanaba amathandathu e-0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, kunye ne-1.6MPa ngala: SDR33/SDR26/SDR21/SDR17/SDR13.6/SDR11.

Okwesithathu, umbuzo wobubanzi bombhobho we-PE

Ngokuqhelekileyo, imibhobho ye-PE inobubanzi obuyi-20mm-1200mm. Idayamitha esithetha ngayo apha eneneni ibhekisa kwidayamitha yangaphandle. Ngokomzekelo, umbhobho we-PE we-De200 1.0MPa ngokwenene i-PE enobubanzi obungaphandle be-200, uxinzelelo lwe-10 kg, kunye nobukhulu bodonga lwe-11.9 mm. umbhobho.

Okwesine, indlela yokubala yobunzima bemitha yombhobho we-PE

Xa abasebenzisi abaninzi beza kubuza malunga nexabiso leUfakelo lwemibhobho yeHdpe, abanye baya kubuza ukuba yimalini ikhilogram, kufuneka sisebenzise isiqwenga esinye sedatha apha-ubunzima beemitha.

Siza kubhala ezinye iifomyula zokubala ubunzima bemitha yeepayipi ze-PE. Abahlobo abasweleyo baya kubakhumbula. Kuya kuba luncedo kumsebenzi wexesha elizayo:

Ubunzima bemitha (kg/m)=(idayamitha yangaphandle-ubunzima bodonga)*ubunzima bodonga*3.14*1.05/1000

Ewe, kuphelele apho kumxholo wanamhlanje. Ukufumana ulwazi oluninzi malunga nemibhobho ye-PE, nceda uqhubeke usithathele ingqalelo. Joyina izandla kunye neShentong ukuphumelela imakethi, wamkelekile ukubuza.
