Welded steel pipes that meet the ASTM A795 specifications are a popular choice in a variety of fire protection applications. These pipes are durable, reliable, and designed specifically for fire sprinkler and standpipe systems.
When it comes to fire protection, reliability and performance are of the utmost importance. The ASTM A795 standard ensures that each pipe meets strict guidelines for strength, durability, and safety to help prevent potential fires and protect property and lives.
Fire sprinkler systems and standpipe systems require pipes that can withstand the high pressures and demands of these critical applications. ASTM A795 welded steel pipes are up to the task and can provide dependable and long-lasting performance in even the most challenging environments.
Our commodity consists of fire sprinkler ERW carbon steel pipes that are perfect for use in construction, building material, and fire sprinkler steel pipelines.
The pipes come in a round hollow shape with sizes ranging from 1/2''-8''. We offer multiple wall thicknesses, ranging from 1.3mm to 10mm.
Standard lengths for the pipes are 5.8m and 6m, but we are able to cut the pipes into other lengths according to PI. They are certified according to ISO 9000-2001 and carry a UL certificate.
Our pipes meet international standards, including ASTM A795, ASTM A53, and GB/T3091. They are made with welded technique, ensuring strength and durability.
The pipes come with surface options of galvanized or painted to prevent rust. Pipe ends can be plain or threaded with sockets/coupling and plastic cap or grooved with caps.
