Tha Pìoba Loidhne gun ròn API 5L air a dhèanamh suas de stuth stàilinn gualain a tha an-aghaidh sgàineadh creimeadh agus a tha an aghaidh caitheamh. Tha carbon, manganese, cromium, nicil agus eileamaidean eile anns an stuth ann an tomhasan lorg.
Is dòcha gu bheil an ìre de loidhne-phìoban stàilinn ERW air a dhèanamh mar a leanas:
