What certifications do you hold?A1: HYT seamless steel pipes strictly adhere to international standards such as ASTM, API 5L/5CT, and EN 10216. We are certified with ISO 9001 Quality Management System, ISO 14001 Environmental Management System, and API Monogram License. Complete material test reports (MTRs) and third-party inspection certificates are provided to ensure compliance.Q2: How do you guarantee key performance metrics like pressure resistance and corrosion resistance?A2: We employ precision hot-rolled/cold-drawn processes combined with full-process non-destructive testing (e.g., ultrasonic testing, eddy current testing). Each batch undergoes chemical analysis and mechanical property tests (tensile/impact testing) to ensure performance. Customized material solutions are available for extreme conditions (e.g., high-temperature/pressure applications).Q3: What is your lead time and delivery capability? Can you handle urgent orders?A3: HYT maintains a large inventory and automated production lines, ensuring a 7-15 day lead time for standard orders. For urgent needs, our "Expedited Channel" enables shipment within 3 working days, supported by a global logistics network for efficient delivery.Q4: Do you support customized specifications (e.g., non-standard sizes, special coatings)?A4: Yes! We offer ODM/OEM services, tailoring outer diameter, wall thickness, length, surface treatment (galvanization, spray coating, etc.), and special alloy compositions. Our technical team responds within 48 hours with a solution.
