Plastic PipeMunicipal and consumer water systems, drainage systems, pools and all other water management applications make extensive use of plastic pipes. A wide variety of plastic pipe construction material is available to accommodate the unique conditions of a given situation; plastic pipes can be made of PVC, high-density polyethylene (HDPE), polypropylene, ABS and many other materials. Each material features advantages. For example, only certain materials like rigid chlorinated PVC and flexible polybutylene can withstand hot water under pressure. Each material features different levels of corrosion and chemical resistance, thermal and electric conductivity, durability and weight. Industries like farming, construction, petrochemical exploration and product development, aerospace, marine and beverage manufacturing rely heavily on plastic pipes in daily operations. Plastic pipes, like all other cylindrical plastic products, can be fabricated through one of several plastic formation methods. The most efficient and effective method, however, is plastic extrusion. The plastic extrusion process begins with a collection of raw plastic stock in a hopper suspended over a conveyance channel. Within the conveyance channel a large turning screw forces the stock toward a tool called a die. A die is any industrial tool used to shape a raw material into a usable product. In the case of plastic piping extrusion, a die is a metal plate with a specially-designed hole in the middle through which the plastic stock will pass. As the turning screw forces the plastic toward the die, friction created by the screw combined with heat from electric heating elements causes the plastic to become molten. Once molten, the plastic is forced through the die. When it emerges on the other side, it is newly-formed plastic piping. At this point, the pipes can be cut to length and prepared for shipment or sent for additional processing. The only difference between pipe extrusion and tube extrusion is the size of the hole cut in the die; pipe dies are much larger than tube dies.
