1. Chii chiri kumanikidzwa kwepombi yePE?

Zvichienderana nezvinodiwa zvenyika zveGB/T13663-2000, kumanikidzwa kweMapaipi ePEinogona kukamurwa kuita mazinga matanhatu: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, uye 1.6MPa. Saka data iri rinorevei? Zviri nyore: Semuenzaniso, 1.0 MPa, zvinoreva kuti kumanikidzwa kwakajairika kwerudzi urwu rweZvishandiso zveHdpei1.0 MPa, inova ndiyo yatinowanzodaidza kuti 10 kg yekumanikidzwa. Ehe, mukuyedzwa kwekumanikidzwa kwapfuura, zvichienderana nezvinodiwa nezvinodiwa zvenyika, inofanira kumanikidzwa ka1.5. Chengeta kumanikidzwa kwemaawa makumi maviri nemana, kureva kuti, bvunzo inoitwa nekumanikidzwa kwemvura kwe15 kg.

2. Ko SDR yepombi yePE inorevei?

Kukosha kweSDR, kunozivikanwawo sechiyero chehukuru hwakajairika, chiyero chedhayamita yekunze nehukobvu hwemadziro. Tinowanzo shandisa kukosha kweSDR kumiririra chiyero chekumanikidzwa kwekirogiramu. Makoshero eSDR anoenderana nematanho matanhatu e0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, uye 1.6MPa ndeaya: SDR33/SDR26/SDR21/SDR17/SDR13.6/SDR11.

Chechitatu, mubvunzo wedhayamita yepombi yePE

Kazhinji, mapaipi ePE ane dhayamita ye20mm-1200mm. Dhayamita yatiri kutaura nezvayo pano inoreva dhayamita yekunze. Semuenzaniso, pombi yePE yeDe200 1.0MPa iPE ine dhayamita yekunze ye200, kumanikidzwa kwe10 kg, uye ukobvu hwemadziro hwepaipi ye11.9 mm.

Chechina, nzira yekuverenga huremu hwemita yepombi yePE

Kana vashandisi vazhinji vachiuya kuzobvunza nezvemutengo weHdpe Pipe Fittings, vamwe vanobvunza kuti kirogiramu imwe ingani, tinofanira kushandisa chidimbu chimwe chete chedata pano - huremu hwemita.

Tichanyora mamwe maforoma ekuverenga huremu hwemita yemapombi ePE. Shamwari dzinoda rubatsiro dzichavayeuka. Zvichabatsira pabasa remangwana:

Huremu hwemita (kg/m)=(ukobvu hwedhayamita yekunze-rusvingo)*ukobvu hwemadziro*3.14*1.05/1000

Zvakanaka, ndizvo zvese zviri muchinyorwa chanhasi. Kuti muwane rumwe ruzivo nezvemapaipi ePE, ndapota rambai muchiteerera kwatiri. Batanai naShentong kuti muwane musika, tinokugamuchirai kubvunza.
