ASTM A795 Fire Pipe

ASTM A795 is a standard specification published by the American Society for Materials and Testing for corrosion-resistant coated welded steel pipes. Pandapipe’s pipes are manufactured in both welded and seamless ways. It covers ASTM A795 Gr.A as well as ASTM A795 Gr.B grades.

Pandapipe offers ASTM A795 steel pipes for a wide range of fire protection applications. The steel pipes we manufacture are treated by hot dip galvanizing technology, and the surface of the steel pipes is black. Thanks to this extra layer of anti-corrosion galvanized coating, the pipe is protected and its service life is extended.
