Product Description
ASTM A335/A335M Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service
1. For Water Supply Lines
-
Material Type: The galvanized (zinc-coated) version (Type E or Type F) is mandatory to prevent internal corrosion and rust contamination of the potable water.
-
Primary Function: Used for the conveyance of cold and hot potable water in residential, commercial, and industrial plumbing systems.
-
Key Advantage: The hot-dip galvanized coating provides a robust barrier, significantly extending the service life of the piping against rust.
-
Installation: Commonly joined using threaded connections and fittings, facilitating straightforward assembly and maintenance.
-
Compliance: Meets essential health and safety standards required by building codes for potable water applications.
2. For Piling
-
Material Type: Typically, the more economical Grade A and black (uncoated) pipe is specified.
-
Primary Function: Serves as foundation piles for light to moderate structures such as buildings, signs, noise barriers, and small bridges.
-
Key Advantage: The cylindrical shape offers high resistance to bending and buckling. The pipe can be filled with concrete to dramatically increase its load-bearing capacity and durability.
-
Installation: Driven into the ground using impact or vibratory hammers. The consistent strength of the ERW seam is crucial for this process.
-
Cost-Effectiveness: Provides a faster and often more economical foundation solution compared to other piling types in suitable soil conditions.
3. For Compressed Air Systems
-
Material Type: Primarily black (uncoated) steel pipe is used for its strength and cost-effectiveness.
-
Primary Function: Transporting compressed air throughout industrial settings such as manufacturing plants, workshops, and garages.
-
Key Requirement: The pipe must be of a sufficient Schedule (e.g., Sch 40 or 80) to safely contain the system's operating pressure without risk of failure.
-
Installation: Assembled via threading or welding to create a strong, sealed network. Systems must include drip legs to drain accumulated moisture.
-
Important Consideration: The interior must be clean and free of mill scale to prevent contamination of air tools. Over time, internal corrosion can occur, so proper air drying and filtration are essential.
