1. Chii chinonzi kudzvinyirirwa kwePE pombi?

Zvinoenderana nezvinodiwa nenyika yeGB/T13663-2000, kudzvanywa kwePE mapaipiinogona kukamurwa kuita matanho matanhatu: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, uye 1.6MPa. Saka iyi data inorevei? Yakareruka kwazvo: Semuyenzaniso, 1.0 MPa, zvinoreva kuti yakajairika kushanda kumanikidza kwerudzi urwu rweHDpe Fittingsiri 1.0 MPa, inova ndiyo yatinowanzodaidza kuti 10 kg pressure. Ehe, muyedzo yekumanikidza yapfuura, zvinoenderana nezvinodiwa zveyero yenyika, inoda kudzvanywa 1.5 nguva. Chengetedza kumanikidzwa kwemaawa makumi maviri nemana, ndiko kuti, muedzo unoitwa nekumanikidzwa kwemvura kwe15 kg.

2. Chii chinonzi SDR kukosha kwePE pipe?

Iko kukosha kweSDR, inozivikanwawo seyero yakaenzana saizi, ireshiyo yedhayamita yekunze kune ukobvu hwemadziro. Isu tinowanzo shandisa iyo SDR kukosha kumiririra iyo kilogram pressure rating. Iwo anoenderana SDR kukosha kwematanho matanhatu e0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, uye 1.6MPa ndeaya: SDR33/SDR26/SDR21/SDR17/SDR13.6/SDR11.

Chechitatu, mubvunzo wehupamhi hwepombi yePE

Kazhinji, mapaipi ePE ane dhayamita ye20mm-1200mm. Chidimbu chatiri kutaura pano chinotoreva dhayamita rekunze. Semuenzaniso, PE pombi yeDe200 1.0MPa inonyatso PE ine dhayamita rekunze re200, kumanikidzwa kwe10 kg, uye kukora kwemadziro 11.9 mm. pipeline.

Chechina, nzira yekuverenga yehuremu hwemamita hwepombi yePE

Kana vashandisi vazhinji vauya kuzobvunza nezve mutengo weHdpe Pipe Fittings, vamwe vachabvunza kuti imarii kilogiramu, tinoda kushandisa imwe chidimbu che data pano-mamita uremu.

Tichanyora mamwe mafomula ekuverenga huremu hwemamita emapombi ePE. Shamwari dzinoshayiwa dzichadzirangarira. Zvichabatsira kubasa remangwana:

Huremu hwemita (kg/m)=(kunze kwedhayamita-madziro ukobvu)*ukobvu hwemadziro*3.14*1.05/1000

Zvakanaka, ndizvo zvese zvemukati zvanhasi. Kuti uwane rumwe ruzivo nezve PE mapaipi, ndapota ramba uchiteerera kwatiri. Bata maoko neShentong kuhwina musika, unogamuchirwa kubvunza.
