The roll groove fittings are made in ductile iron to ASTM A536 Grade 65-45-12. This version is galvanised, and gives its coating as hot dip zinc galvanising. Roll groove suits standard pipe with cut grooves, or standard and light wall pipe with rolled grooves. The working pressure is 2500 kPa and the maximum working temperature is 100 °C. Working pressures may also be limited by pressure piping codes or industry regulations.
