What is ASTM A795/A795M?

Product Description: UNIASEN is proud to present our ASTM A795/A795M standardized Steel Pipe, an exceptional choice for fire protection applications.

This pipe comes in two variants – black and hot-dipped zinc-coated, both welded and seamless, ensuring a sturdy and dependable structure.

The pipe is designed to be bent, but 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 there is no leakage. We also offer an alternative non-destructive electrical method testing, if preferred by the customer.
