Chlorine pipe manufacturing process: First, the use of PTFE (powder), push (squeeze) pressed into the tube, then it was forced to pull into seamless steel pipe (pipe inner diameter slightly larger than the outside diameter of the liner 1.5-2mm), to form a gapless tight lining, In order to eliminate stress, put it in an oven heated to 180 ℃ constant temperature treatment, to adapt for use in the temperature below 180 ℃. At the same time push (squeeze) pressure pipe axial tensile strength significantly better than the Pipe. This pipe has the desired resistance to positive and negative pressure capability. ◆ Path Specifications: DN25-200mm ◆ Operating temperature: -100-180 ℃ ◆ applied pressure: -0.09-1.6MPa
