API 5CT OCTG L80 Soláthraí feadánra
Tagraíonn foirm ghearr Earraí Tubular Tír Ola (OCTG) den chuid is mó do chásáil agus feadánra ach féadann siad tagairt a dhéanamh freisin do phíobán líne a úsáidtear chun ola agus gáis a iompar agus a thaiscéaladh.
Baineadh úsáid as cásáil agus é ag druileáil tobar.Tá cásáil curtha sa tobar agus stroighin, rud a choinníonn an poll ó sloughing isteach agus an próiseas druileála nó táirgthe.Tar éis feadánra críochnúil a chur isteach, is é feadánra an píopa trína sreabhann ola agus gáis go dtí an dromchla.
