Abstract
The invention provides a method for making an organism deposit-inhibition pipe, which excels in corrosion resistance, dispenses with maintenance work, and offers no toxicity problems. A thin sheet comprising a copper alloy is wound spirally around a round bar and inserted into a resin pipe made up of an electrical insulating material. And the round bar is taken out. The obtained pipe has an inner wall which is covered with the copper thin sheet. The copper alloy has a Be content of 0.2 to 2.8% by weight, and is selected from, e.g., Be--Cu, Be--Co--Cu, Be--Co--Si--Cu and Be--Ni--Cu alloys. The beryllium-copper alloy has a remarkable antifouling effect and provides a continued liberation of copper ions.
