?s¨¢idtear p¨ªopa¨ª builte gan chro¨ª go leathan. Nuair is m¨® n¨¢ 1.5 uair diam¨¦adar an p¨ªopa rada boilte an p¨ªopa cruach, ¨²s¨¢idtear builte gan chruach i gcoitinne. N¨ª ¨²s¨¢idtear pr¨ªomhp¨ªopa¨ª beoga ach amh¨¢in le haghaidh p¨ªopa¨ª cruach a bhfuil diam¨¦adair n¨ªos m¨® acu agus ti¨²s bhalla n¨ªos thinner.
Ina theannta sin, t¨¢ modhanna chun p¨ªopa¨ª a bhogadh amhail bl¨²ite barrbhr¨², bl¨²ite me¨¢nphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhphr¨ªomhph
Piopa cruach
T¨¢ dh¨¢ chine¨¢l p¨ªopa¨ª cruach ann: p¨ªopa¨ª cruach neamhshl¨ªonta agus p¨ªopa¨ª cruach suaite.
p¨ªopa cruach neamhsh¨¢ilte
Roinntear p¨ªopa¨ª cruach neamhsh¨®ill¨ª i bp¨ªopa¨ª teasrollaithe, p¨ªopa¨ª fuar tarraingthe, p¨ªopa¨ª eastr¨²ite, srl. De r¨¦ir cruth thrasnaigh, t¨¢ dh¨¢ chine¨¢l ann: ciorcal agus neamhrialta. De r¨¦ir cr¨ªocha ¨¦ags¨²la, t¨¢ fead¨¢in tiubha ball¨¢iste agus tiubha ball¨¢iste, agus ¨²s¨¢idtear fead¨¢in tiubha ball¨¢iste le haghaidh p¨¢irteanna miotail leath¨¢in de ghn¨¢th.

T¨¢ p¨ªopa cruach suaite, ar a dtugtar p¨ªopa cruach suaite freisin, d¨¦anta tr¨ª stiallacha cruach suaite agus a thagann i dh¨¢ chine¨¢l: galvanized and non galvanized. The former is called white iron pipe, and the latter is called black iron pipe.
D¨¦antar sonra¨ªochta¨ª p¨ªopa¨ª cruach a shloinneadh i gc¨®ras m¨¦adrach mar diam¨¦adar seachtrach agus ti¨²s balla, agus i gc¨®ras imp¨¦iriach mar diam¨¦adar inmhe¨¢nach (orlach).
Is ¨¦ an modh marc¨¢la m¨¦id le haghaidh p¨ªopa¨ª cruach: diam¨¦adar seachtrach, ti¨²s balla, agus fad, amhail p¨ªopa D60106000
Modh ceangail na bp¨¢irteanna miotail leath¨¢in:
T¨¢ p¨¢irteanna miotail bileoga comhdh¨¦anta de go leor comhph¨¢irteanna nach m¨®r iad a cheangal ar bhealach ¨¢irithe chun t¨¢irge ioml¨¢n a fhoirmi¨². ?ir¨ªtear ar na modhanna ceangail a ¨²s¨¢idtear go coitianta sol¨¢thar, sciathr¨², ceangal sn¨¢ithithe agus comhph¨¢irt leathnaithe. Glacann an nasc idir p¨ªopa¨ª cruach leis na modhanna thuasluaite freisin. Maidir le sol¨¢thar, sciathr¨² agus ceangail sn¨¢itheacha
Is modh ceangail ¨¦ comhph¨¢irt leathanta a ¨²s¨¢ideann d¨ªfhoirmi¨² p¨ªopa cruach agus pl¨¢ta¨ª p¨ªopa chun s¨ªol¨² agus socr¨² a bhaint amach.
