Sonraíocht Chaighdeánach ASTM A671 le haghaidh Píob Cruach Táthaithe Leictreach-Fusion le haghaidh Atmaisféir agus Teochtaí Íseal
Is sonraíocht chaighdeánach é ASTM A671 a chlúdaíonn píopa cruach leictreach-chomhleá-táthaithe le miotail líonta curtha leis, déanta as pláta cáilíochta soitheach brú de roinnt anailísí agus leibhéil neart, agus atá oiriúnach do sheirbhís ardbhrú ag teocht an atmaisféir agus níos ísle. D’fhéadfadh nó nach mbeadh cóireáil teasa ag teastáil chun na hairíonna inmhianaithe a bhaint amach nó chun ceanglais an chóid is infheidhme a chomhlíonadh. Soláthraítear ceanglais bhreise lena n-úsáid nuair is gá tástáil nó scrúdú breise a dhéanamh.
Clúdaíonn an tsonraíocht píopa 16 isteach go hainmniúil [400mm] trastomhas lasmuigh nó níos mó agus 1/4 isteach [6mm] tiús bhalla nó níos mó. Is féidir píopa le toisí eile a sholáthar ar choinníoll go gcomhlíonann sé ceanglais eile na sonraíochta seo.
