[0027] Plastic pipe is a high-tech composite chemical building material, and chemical building material is a new type of building material after steel, wood and cement.

[0028] Plastic pipe is widely used in the fields of building water supply and drainage, town water supply and drainage and gas pipe at present due to the advantages of small water flow loss, energy saving, material saving, ecological protection and convenient completion, and becomes the main force of new century city construction pipe network.

[0029] The pace of technological progress is faster than traditional materials, and the new technology, new materials, new technology constantly emerging make the advantage of plastic pipe relative to traditional materials more and more prominent. Compared with traditional metal pipes and cement pipes, plastic pipes have the advantages of light weight, generally only 1 / 6-1 / 10 of metal pipes, good corrosion resistance, impact resistance and tensile strength, smoother inner surface than cast iron pipes, smaller friction coefficient, smaller fluid resistance, more than 5% reduction in water conveying energy consumption, comprehensive energy saving, manufacturing energy consumption reduction of 75%, convenient transportation, simple installation and long service life of 30-50 years. Polyethylene pipes not only replace traditional steel pipes, cast iron pipes and other pipes, but also replace polyvinyl chloride pipes. The reason is that polyethylene pipe technology has been innovated in the past 10 years. On the one hand, the material has made great progress. Through the improvement of polyethylene polymerization production process, the strength of polyethylene pipe special material has increased by almost 1 times. On the other hand, the application technology has new development. For example, in recent years, without digging pipe trench, using directional drilling method to lay polyethylene pipe can fully play the advantages of polyethylene pipe, so that traditional pipes have no competitiveness in suitable occasions.

[0030] Extrusion, especially cold extrusion, has high material utilization, improved material organization and mechanical properties, simple operation, high productivity, and can produce long rods, deep holes, thin walls, and special-shaped section parts. It is an important non-cutting machining process. Extrusion is mainly used for metal forming, and can also be used for non-metal forming of plastics, rubbers, graphite and clay blanks. In the 17th century, French people used hand-operated screw presses to extrude lead pipes for water pipes, which was the beginning of cold extrusion. Cold extrusion of zinc, copper and copper alloys was realized at the end of the 19th century, and expanded to aluminum and aluminum alloy extrusion in the early 20th century. In the 1930s, the Germans invented a surface friction-reducing lubrication treatment technology of phosphating and saponification, which made the cold extrusion of steel successful, and was initially used for extruding steel cartridges. After the Second World War, steel cold extrusion was popularized in other countries and expanded its application range. In the 1950s, molten glass lubrication method was adopted, and steel hot extrusion was applied and developed in the metallurgical and mechanical industries.

[0031] Extrusion can be divided into hot extrusion, cold extrusion and warm extrusion according to the temperature of the billet. When the metal billet is above the recrystallization temperature, it is hot extrusion; when it is at room temperature, it is cold extrusion; when it is above room temperature but not more than the recrystallization temperature, it is warm extrusion. According to the plastic flow direction of the billet, extrusion can be divided into: positive extrusion with the same flow direction as the pressure direction, reverse extrusion with the opposite flow direction as the pressure direction, and composite extrusion with the billet flowing in both positive and reverse directions.

[0032] Hot extrusion is widely used to produce tubes and sections of non-ferrous metals such as aluminum, copper, etc. and belongs to the range of metallurgical industry. Hot extrusion of steel is used to produce special tubes and sections as well as solid and hollow (with or without hole) parts of carbon steel and alloy steel such as rod with thick head, barrel, container, etc. which are difficult to be formed by cold or warm extrusion. The dimensional accuracy and surface finish of hot extruded parts are better than those of hot forged parts, but the fitting parts still need to be finished or cut. Cold extrusion was originally used to produce tubes and sections of lead, zinc, tin, aluminum, copper, etc. as well as toothpaste tube (tin-coated lead), dry cell shell (zinc), shell (copper), etc. In the middle of 20th century, cold extrusion technology began to be used for carbon structural steel and alloy structural steel parts such as various cross-section rods and rod-shaped parts, piston pin, wrench sleeve, straight spur gear, etc. and later for some high carbon steel, rolling bearing steel and stainless steel parts. Cold extruded parts have high precision and surface finish and can be directly used as parts without cutting or other finishing. Cold extrusion operation is simple and suitable for small parts in large quantities (steel extruded parts are generally not larger than 100 mm in diameter).

[0033] Warm extrusion is an intermediate process between cold extrusion and hot extrusion. In appropriate cases, warm extrusion can have the advantages of both. However, warm extrusion needs to heat the blank and preheat the die, the high temperature lubrication is not ideal, and the die life is short, so it is not widely used.
