体の長距離輸送に適するものとして注目されている。In order to solve these problems, the inventors of the present invention installed a metal nozzle such as an aluminum pipe or a stainless steel pipe, or a polyvinyl chloride pipe or a polyethylene pipe on the outer periphery of the lead pipe in close contact with the lead pipe. We have developed a composite pipe with an outer layer of plastic pipe, etc. Such composite pipes have the advantage that they have moderate A properties, can be transported in drums, and can be easily manufactured using existing equipment, and have low internal pressure resistance. The inner layer lead pipe and the outer layer pipe bear the burden, and the outer layer pipe bears the burden of trauma resistance, so it is attracting attention as being suitable for long-distance transportation of fluids.
