Product Name: Steel Pipe Lining PTFE. Model NO.: DN25-1700 Connection Type: Flange Cross-Section Shape: Round Medium: Liquid Diameter: 273mm Standard: ASTM, GB, API, DIN, JIS Material: Carbon Steel MPa Classfication: Low Pressure Piping Temperature Classification: Medium Temperature Piping Process: Lining or Coated Trademark: none Transport Package: Wooden Pallet Specification: DN25-170x2000MM Origin: China HS Code: 73043100 Product Description Steel-lined PTFE pipe has three processes suitable for different working conditions1.PTFE powder is used to extrude into a pipe. The surface is chemically treated and then lined into a seamless steel tube (the outer diameter of the tube is slightly larger than the inner diameter of the steel tube) to form a seamless gap. In order to eliminate stress, it is placed in a furnace and heated to 180 degrees for constant temperature treatment to make it suitable for use at temperatures below 180 degrees. At the same time, the axial tensile strength of the extruded pipe is obviously better than that of the wound pipe, and it can be used in micro-negative pressure pipelines.2.PTFE isotonic molding, using polytetrafluoroethylene resin directly with metal pipes as molds and then sintering with pipes, isotonic molding, and can withstand full vacuum working environment, working temperature -30-180 ºC3.PTFEwinding molding, using PTFE tape to wind on the outer wall of the pipe, and then sintering with the pipe, suitable for PTFE lined molding with complex shapes.
