All of the known world piping for industrial use on the material from which they are made, can be divided into two groups: metallic and nonmetallic. The main distinguishing feature of PEX tubing – strength, non-metal – corrosion resistance and, consequently, longevity. And it is well known that the mechanical properties of steel tubing, for example, in plumbing systems and wastewater are used by only 2-4%.
As most of the first PEX tubing, which began using people most likely was a reed or wood with vygnivshey core. With their man managed to secure plumbing to his house or in the field, ie him in the right direction. It was a great discovery, because in the absence of directional movement that changes can not accumulate and the process is deprived of a single internally coherent line. At the end of the Stone Age, along with tubing made of wood began to use tubing made of clay. In the Copper Age came into use copper tubing. Appeared about 3000 BC bronze tube expanded the scope of tubing. The first cast-iron tubing were cast in 1465, they have allowed humanity to radically solve the issues of plumbing and sanitation. It should be noted this feature of tubes: they were manufactured from virtually all types of materials that are opening up to humanity.
PEX tubing made of new materials emerging with as new demands by consumers for them, or when there are certain conditions that require the use of tubular products from new materials, or other properties. For example, wood, pottery, tubing made of nonferrous metals for a long time to satisfy the demand of construction and repair. But when the increased requirements for ease of handling, there were more perfect cast iron tubing. In the first place with their help protect the plumbing and Plumbing removal. Almost 400 years a set of tubing to satisfy the needs of users. The first steel tubing appeared only in 1852 and were made from a sheet by welding. Further improvements in technology allowed the manufacture of metal-rolling seamless steel tubing. Steel tubing have always acted as a catalyst in accelerating technological progress, their application provides an opportunity to use innovative design solutions radioed mechanisms, structures. For example, with a steel tubing steam was used as a driving force in vehicles and as a source of heat. The use of steel tubing in industrial and residential construction has created more sophisticated devices for radiant heating, lighting, plumbing and sanitation. From steel tubes may be constructed a considerable length of tubing, using their high blood pressure, which is especially important for transportation of oil and gas.
