ASTM A795

UNIASEN proudly presents our ASTM A795/A795M pipe. It is an excellent choice for fire protection.

This pipe comes in two variants:

Black and hot-dipped zinc-coated
Welded and seamless

The pipe is designed to be bent. However, it is not at ambient temperature if the bend’s inside diameter is less than twelve times the pipe’s outside diameter.

Each pipe is subjected to a thorough hydrostatic test to ensure no leakage. If the customer prefers, we also offer an alternative non-destructive electrical method of testing.
