DHF Bi-met™ DML is a bimetallic tube, where a highly wear and corrosion resistant self-fluxing alloy or hard particle diffusion composite coated lining with Self fluxing (SF) alloy matrix is formed on the inner surface of a steel tube by means of the high frequency induction heating (IH) process.
Characteristics
- Highly reliable quality: diffusion bonding between the base material (steel tube) and coated lining eliminates peeling and corrosion.
(IH process results in high consistency, reproducibility and powerful diffusion bond with lining interface) - High adaptability to respond to customer needs
- ① Optimum lining design: capable of optimally designing (with maximum cost performance) the coated lining required (material, thickness) depending on service conditions, installation location, target service life, and other factors.
- ② Our core technology—the IH bending process—can be applied, enabling the products to serve in various transfer system units.
“One stop” service DHF can do it all: procure base pipe/substrate, pipe bending, application of inner lining, flange welding, painting.
