Is cineál píopa cruach gan uaim é píopa cóimhiotail, tá a fheidhmíocht i bhfad níos airde ná mar a bhaineann le píopa cruach gan uaim ginearálta, toisc go bhfuil níos mó Cr ag an gcineál seo de phíobán cruach, tá a fhriotaíocht teocht ard, friotaíocht íseal teochta, feidhmíocht friotaíocht creimeadh i bhfad níos fearr ná mar a chéile. Píobán cruach, mar sin úsáidtear an píopa cóimhiotail go forleathan i dtionscail peitriliam, aeraspáis, ceimiceacha, leictreacha, coire, míleata agus tionscail eile.
