Q1: 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).

Q2: 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.

Q3: 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.
