Abstract
A pipe according to the present disclosure comprises: a hollow tube body in which fluids of different temperatures pass through the inside and outside thereof; and a coating layer which is provided on an external surface of the hollow tube body, and which has an alloy comprising an amorphous phase, wherein the alloy comprises Fe, and comprises at least one or more first component selected from the group consisting of Cr, Mo and Co, and at least one or more second component selected from the group consisting of B, C, Si and Nb.
Claims15
A pipe, comprising:
- a hollow tube body in which fluids having different temperatures pass through the inside and the outside thereof;
- and
- a coating layer provided on an external surface of the hollow tube body and having an alloy including an amorphous phase,
- wherein the alloy includes Fe, and
- at least one or more first component selected from a group consisting of Cr, Mo and Co, and at least one or more second components selected from a group consisting of B, C, Si and Nb.
The pipe of claim wherein the coating layer has a coating density of 98 to 99.9%.
A method of manufacturing a pipe, the method comprising:
- preparing an alloy powder, including preparing an alloy powder having a composition including at least one or more first components selected from a group consisting of Cr, Mo and Co and at least one or more second components selected from a group consisting of B, C, Si and Nb, and Fe;
- and
- forming a coating layer, including forming a coating layer having an amorphous phase by thermally spraying the alloy powder to an external surface of a hollow tube body.
