Title:
クラッド管を製造する方法及びクラッド管
Document Type and Number:
Japanese Patent JP5896995
Kind Code:
B2
Abstract:
The manufacture of clad tubes (30) is described. Tube (10) intended to line the walls of a combustion chamber is made of a high strength material to contain the high-pressure steam created. However, these tubes (10) are typically not corrosion/erosion resistant. Manufacture of tubes (10) with both high strength and high resistance to corrosion/erosion would be prohibitively expensive. Therefore, tubes (10) are covered with a non-corrosive material to protect them. This is done by surface welding a strip (20) of high alloy material to the outer surface (12) of the tubes (10). It is preferable to use electric high frequency resistance welding to surface weld the strip (20) onto tube (10). The strips (20) are preferably attached with little melting and metal dilution allowing the strip 20 to keep its corrosion/erosion resistance properties.
