Déantar píopa druileála ó tháthú trí phíosa ar a laghad: comhpháirteach uirlisí bosca, comhpháirteach uirlisí bioráin, agus an feadán.Déantar foircinn na bhfeadán a mhúscailt ansin chun limistéar trasghearrthach na foircinn a mhéadú.D’fhéadfadh deireadh an fheadáin a bheith trína chéile go seachtrach (AE), trína chéile go hinmheánach (IU), nó trína chéile go hinmheánach agus go seachtrach (IEU).Sonraítear toisí caighdeánacha trína chéile caighdeánach in API 5DP, ach tá toisí beachta an trína chéile dílseánaigh don mhonaróir.Tar éis trína chéile, téann an feadán trí phróiseas cóireála teasa.Is gnách go ndéantar cruach píopa druileála a mhúchadh agus a mhaolú chun láidreachtaí ard-toraidh a bhaint amach
Is cineál feadáin chruach é píopa druileála le heireaball snáithithe, a úsáidtear go príomha chun trealamh dromchla rig druileála agus trealamh druileála agus meilt nó feiste poll bun ag bun an druileála a nascadh.Is é cuspóir an phíopa druileála láibe druileála a iompar chuig an giotán agus an gléas poll bun a ardú, a ísliú nó a rothlú mar aon leis an giotán.Caithfidh an píopa druileála a bheith in ann brú mór inmheánach agus seachtrach, casadh, lúbadh agus tonnchrith a sheasamh.Sa phróiseas eastóscadh ola agus gáis, is féidir píopa druileála a úsáid go minic.Is féidir píopa druileála a roinnt ina thrí chineál: Kelly, píopa druileála agus píopa druileála ualaithe
