Explosive Welded Titanium Clad Steel Plate For Pressure Vessel Reactor Lining
Published by Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd on 2026-10-25
1. Product Identity
Manufactured in Shaanxi Baoji China, titanium clad steel plate adopts explosive welding process to realize solid‑state metallurgical bonding between titanium cladding layer and carbon steel base layer. Different from simple mechanical sticking or lining tile assembly, explosive impact creates atomic‑level combination at bonding interface. Base steel undertakes mechanical load and pressure bearing; titanium cladding provides corrosion resistance against chloride and brine medium. Widely used for chemical pressure vessel, reactor, distillation tower, heat‑exchanger shell lining. We supply raw clad panel, post‑rolling clad plate and custom cut‑to‑size blanks for equipment fabrication factories.

4. Mechanical & Corrosion Performance
-
Overall mechanical property depends on carbon‑steel base material; titanium cladding provides anti‑corrosion performance.
-
Interface shear strength: Strictly controlled to avoid layer delamination under pressure and thermal cycling condition.
-
Corrosion Resistance: Titanium cladding resists seawater, brine and chloride‑containing corrosive medium; base steel bears internal pressure and structural load.
-
Processing Feature: Special welding procedure is required for field fabrication; direct fusion welding across titanium‑steel interface is forbidden. Edge sealing treatment must be implemented to prevent medium penetration into bonding gap.
5. Full Size Range
-
Cladding titanium thickness: Custom thin cladding layer according to anti‑corrosion requirement
-
Carbon‑steel base thickness: Determined by pressure‑vessel mechanical design calculation
-
Dimension: Large original composite panel, support cutting into special‑shape blanks
-
Custom options: Edge pre‑sealing, local non‑cladding reserved area, flattening treatment after explosive welding.
6. Surface Treatment Options
-
As‑explosive surface: Raw composite panel surface, for further equipment processing.
-
Grind cladding side: Polish titanium layer surface, remove explosive residual impurities.
-
Pickling for titanium face: Remove oxidation on corrosion‑resistant cladding layer.
-
Base‑side blasting: Shot‑blast carbon‑steel base for painting and anti‑rust protection.
7. Material Comparison: Titanium Clad Steel Plate vs Full Solid Titanium Plate

Item
|
Titanium‑Steel Clad Plate
|
Solid Full Titanium Plate
|
|
Material cost
|
Greatly reduced, only thin titanium cladding layer
|
High cost, whole‑plate expensive titanium material
|
|
Pressure bearing capacity
|
Carbon‑steel base undertakes main structural load
|
Rely entirely on Titanium Plate thickness
|
|
Thermal‑cycling risk
|
Require qualified bonding strength & edge sealing
|
No delamination risk, homogeneous single material
|
|
Typical application
|
Large‑size pressure vessel, tower reactor shell
|
Small‑size equipment, non‑clad structure component
|
Titanium‑steel clad plate achieves corrosion‑resistance and pressure‑bearing capacity meanwhile, significantly cutting total investment for large‑sized chemical process equipment.
8. Strict Quality Control & Test Items
-
Raw Titanium Plate and pressure‑vessel steel plate incoming inspection.
-
Explosive welding process parameter validation for each batch.
-
Ultrasonic UT scanning 100% for bonding interface, detect un‑bonded area and void defect.
-
Interface shear strength mechanical sampling test for composite qualification.
-
Visual inspection on titanium cladding surface for crack and scratch.
-
Issued documents: EN10204 3.1 MTC, UT bonding inspection report, shear strength test record, batch traceability file.
9. Export Packaging & Shipment
-
Inner packing: Protective rubber film cover on titanium cladding surface to avoid scratch and iron contamination.
-
Outer packing: Heavy‑duty fumigated wooden support frame, prevent plate bending and collision in sea freight.
-
Marking: Label cladding grade, base steel grade, UT batch number on plate corner.
-
Trade terms: FOB, CIF, DDP; sea freight for large heavy composite panel project orders.
