Abstract: The traditional plastic tube and pipe compared with light weight, corrosion resistance, water resistance of small, energy conservation, rapid and easy installation, low cost, and other significant advantages, the pipeline by the engineering of all ages. For this reason, many developed countries and manufacturers of plastic pipe for a wide range of engineering, has invested a lot of manpower, material and financial resources to conduct a comprehensive study on the development, production of raw materials, pipe fittings manufacturing technology, design and construction of Technology and other areas has been to develop and improve, and has accumulated rich experience in practice, to the plastic pipe in pipeline projects occupy a very important position, and the formation of a unstoppable trend of development. Pipes and rely mainly on the production of processed into the extrusion, this paper plastic extrusion of the various issues.
