Latest Patents

Nishimura holds a patent for a multi-layered anti-coking heat resisting metal tube and the method for manufacturing it. This invention features a multi-layered heat resistant metal tube that exhibits excellent anti-coking characteristics. It is particularly suitable for environments where carbon deposits tend to accumulate due to contact with hydrocarbons at high temperatures. The tube is constructed by forming a weld-mounted overlaid layer of a Cr–Ni–Mo alloy through build-up welding on the inner and/or outer surfaces of a substrate tube made from heat resistant metal. The alloy composition includes, by weight %, Cr: 36-49 wt %, Ni: 35-63 wt %, and Mo: 0.5-5 wt %. The preferred method for building-up welding is Plasma Powder Welding (PPW), where the filler metal is supplied in powder form.
