FAQ

Q: How does ASTM A515 compare with ASTM A516?

A: ASTM A515 is intended for intermediate and elevated-temperature pressure vessel service, while ASTM A516 is generally selected for moderate and lower temperature applications.

Q: Can third-party inspections be arranged before shipment?

A: Yes. SGS, BV, TÜV, LR, DNV, ABS and other designated inspection agencies can be arranged upon request.

Q: Can different grades and sizes be loaded in one container?

A: Yes. Mixed loading of different grades, dimensions, and processed plates is available to optimize freight costs.

Q: Which Incoterms do you support?

A: EXW, FOB, CFR, CIF, CPT, CIP, DAP, DDP, and other negotiated Incoterms.

Q: Which ports do you usually ship from?

A: Primary export ports include Qingdao, Tianjin, and Shanghai, depending on production location and vessel schedule.

Q: Do you keep ASTM A515 plates in stock?

A: Yes. Common thicknesses and standard plate sizes are normally available for prompt shipment, subject to inventory.

Q: What material equivalents are available for ASTM A515?

A: Common equivalents include ASME SA515, while equivalent material selection for EN, JIS, or GB standards can be recommended according to project specifications.
