Here are some key details about the ASTM A53/A135 specifications that 1030 carbon steel pipe is produced to:
ASTM A53 is the standard specification for pipe, steel, black and hot-dipped, zinc-coated (galvanized) welded and seamless. It covers dimensions, chemical properties, mechanical properties, workmanship and finishing requirements for black and zinc-coated steel pipes intended for ordinary uses.
ASTM A135 is similar but deals specifically with electric-resistance welded pipe. It references A53 for chemical requirements but has separate mechanical and dimensional thresholds that account for the electric welding process used during manufacture.
Both standards establish chemical composition limits including for carbon content in different grades of steel pipe. Mechanical property tests like tensile strength must also be met based on pipe size, wall thickness and heat treatment.
Manufacturing, inspection and acceptance criteria ensure quality and consistency. This includes mandates for inspection, NDT testing like ultrasonic, and defect/repair limits.
Together A53 and A135 provide structure for producers while also protecting buyers by guaranteeing 1030 pipe conforms to these standards and known performance benchmarks for typical applications. Let me know if any part of the specifications need clarification!
