With brine transportation pipeline of Huai\'an-Lianyungang alkali company as example,this paper analyzes and discusses environmental protection and safety of brine transportation pipeline engineer-ing.

Under certain physical and chemical conditions,when the brine transportation pipe is in the operating process,the fall of brine transportation pipe fittings and the deposit of suspended substances and chemical substances in brine cause the scale formation on pipe wall.
