ASTM A135

ASTM A135 is an important standard for electric-resistance-welded steel pipe. The standard covers two grades of pipe (Grade A & Grade B) that are intended for conveying gas, vapor, water, or other liquid. The most important aspect of the standard is the requirement that the weld seam of Grade B pipe be heat treated after welding or processed in such a manner that no untempered martensite remains. This requirement is critical to ensuring the strength and durability of the pipe. ASTM A135 is just one of many standards that companies must adhere to in order to produce high-quality pipes that will meet the needs of their customers.

One of the most important parts of a fire safety system is the fire sprinkler. Fire sprinklers are designed to provide water to suppress or extinguish a fire. They are usually located on the roof or the top floors of a building, and the pipes that carry the water are typically painted red so that they are easily visible in the event of a fire. Fire sprinklers are usually activated by heat, and the water is discharged through sprinkler heads that are located throughout the building. In most cases, only the sprinklers closest to the fire will activate, which minimizes water damage. Fire sprinklers are an essential part of any fire safety system, and their use can help to save lives and property.
