Our titanium-steel composite heads are designed for use in the most demanding applications in the chemical processing industry (CPI). This composite head combines the exceptional corrosion resistance of titanium with the high structural strength and cost-effectiveness of carbon steel. They are the ideal solution for pressure vessels, reactors and storage tanks that handle highly corrosive substances such as chlorides, acids and oxidising chemicals. They ensure long-term reliability and safety while optimising lifecycle costs.
Titanium Steel Clad Head Sheet
Compliance: Meets ASME, PED and other international standards.
Material traceability: Full traceability from raw materials to finished products.
Non-destructive testing (NDT): Ultrasonic testing (UT), radiographic testing (RT) and dye penetrant testing (PT) are used to assess the integrity of the base material and joints.
Key features and benefits for Titanium Steel Clad Head Sheet
Unmatched corrosion resistance: Titanium alloy cladding (grades 1 or 2) provides outstanding protection against pitting, crevice corrosion and a variety of corrosive chemicals, preventing internal erosion of vessels.
High structural integrity: Backing materials made from carbon steel or low-alloy steel (SA-516 Gr. 70, SA-387 Gr. 11/12, etc.) provide essential mechanical strength, enabling the vessel to withstand high pressures and structural loads.
Cost-effective solution: This is a significantly more economical solution than solid titanium alloy heads, delivering titanium-equivalent performance at minimal cost.
Perfect Bonding: Manufactured using advanced explosion or hot-rolled bonding techniques to ensure metallurgical bonding with a shear strength that exceeds ASTM B898 standards.
Manufacturing precision: Precision-formed to meet stringent dimensional tolerances (ASME Section VIII, Division 1). Seamless or welded backing steel structures are available.
Extended Service Life: Significantly reduces maintenance downtime and replacement costs, delivering an exceptional return on investment.
