VIII. Professional FAQs: Roll Bonding Cladding Technical FAQ

Q1. What are the primary materials used for base and clad layers in roll bonding cladding?
A: The base is mostly carbon steel, low alloy or boiler plate (e.g., Q235, SA516), while the clad layer can be austenitic stainless steel (304L, 316L), nickel alloys (Alloy 825/625), titanium, or copper. Selection is dictated by end-use corrosion and strength demands.

Q2. How is the bond quality between layers assured?
A: Each plate or pipe undergoes non-destructive testing (ultrasound per ISO 15614-7, etc.), shear testing, and local metallographic sampling. A minimum bond strength (>350 MPa, typically) is validated before release.

Q3. What is the typical clad-to-base thickness ratio and what tolerances can be achieved?
A: For plate, 2–20 mm clad over 8–120 mm base (ratio 1:5 to 1:20) is common. Using Cladding Rolling Mill control, thickness tolerances down to ±0.15 mm are achievable, surpassing standard hot rolling.

Q4. Which global standards are referenced for roll bonding cladding and clad pipe welding?
A: Major relevant standards: ASTM B898 (bonded clad plate), ASME SA264 (specification), ISO 15614-7 (weld qualification), API 5LD (clad line pipe), GB/T 8165 (Chinese bimetal plates).

Q5. What are the recommended installation and inspection procedures for clad pipes?
A: Weld surfaces must be free of cracks and defects, with end prepping (beveling) per ISO 9692-2 or ASME B31.3. After clad pipe welding, UT and hydrostatic tests ensure integrity, and interlayer corrosion is checked according to client specs.

Q6. What after-sales service and technical support does YWLX provide?
A: YWLX offers a 3-year mechanical & control system warranty for Cladding Rolling Mill, overseas commissioning, operator technical training, and lifetime remote diagnostic support with 24/7 quick-response hotline. Spare parts guaranteed for ≥10 years.

Q7. What is the typical delivery cycle, and what project documentation is supplied?
A: Typical lead time is 120–180 days ex-works, including FAT, painting, and main power-on testing. Documentation includes material certs, NDE/UT/visual inspection reports, PLC program backups, O&M manuals, and project as-built dossier per ISO/CE.
