Description
Fire Sprinkler Steel Pipe General Product Information
ASTM A795 is a standard specification for black and hot-dipped zinc-coated (galvanized) welded and seamless steel pipe for fire protection use. The pipe is intended for use in fire protection systems, and it is commonly used with grooved ends for easy installation.
Carbon steel pipe grooved ends allow for quick and secure connections using mechanical couplings, which are often used in fire protection systems for their reliability and ease of installation.

Hydrotest:
The hydrostatic test shall be applied, without leakage
through the pipe wall, to each length of pipe.
Coating, Lengths, Dimensions:
During and after production, 4 QC staffs with more than 5 years experience inspect products in random.
