Expert FAQ – Seamless Steel Tube & ASTM A632

Q1: What materials are commonly used for seamless steel tube production?
A: Most frequently used are carbon steel (ASTM A106, A53), alloy steel, and austenitic stainless steel grades (such as ASTM A632, A312). You can refer to ScienceDirect: Seamless Steel Tube Materials for an in-depth discussion.
Q2: What are the standard sizes and thicknesses?
A: Diameter ranges from 6mm up to 610mm; wall thickness varies between 0.5mm to 60mm. Custom lengths of up to 12m or as per client specification are available.
Q3: What is ASTM A632, and why is it significant?
A: ASTM A632 is a specification for seamless and welded austenitic stainless steel pipes for small diameter applications, emphasizing excellent corrosion and temperature resistance. It requires stringent testing for performance reliability.
Q4: How is corrosion resistance ensured?
A: Through precise material selection (304, 316, etc.), surface treatments (pickling, passivation, polishing), and rigorous testing for pitting/crevice corrosion.
Q5: What installation standards are followed?
A: International standards such as ASME B31.3 (Process Piping), DIN EN 10216 (EU Spec.), and ASTM standards are adhered to, ensuring safety and regulatory compliance.
Q6: How are pipes tested before delivery?
A: Each seamless steel tube is subjected to hydrostatic, nondestructive (ultrasonic, eddy current), and mechanical tests. Details are provided in mill certificates and test reports.
Q7: What documentation does CANGZHOU YULONG STEEL CO.,LTD. provide?
A: Full mill certificates, third-party inspection reports, and product traceability records are available for every order.
