History

If iron and copper serve humanity for many centuries, then nickel is just over 250 years old. Until the mid-18th century, the miners of Saxony, when they extracted copper ore, met a breed from which nothing could be smelted. Only metal in 1751 was allocated by the Swedish metallurgist A. Kronstedt, who considered it to be a semimetal. Semimetals called substances that are similar in their properties to metals and nonmetals. Nickel was originally in demand only from jewelers, and in industry it was impossible to use because of sulfur impurities. With the beginning of the twentieth century and the advent of new technologies, the old dream of metallurgists for the manufacture of a wide variety of stainless steels has come true.

Properties

By its properties, Ni is a very hard, viscous, ductile metal. It is easily polished, and in air at ordinary temperature it is covered with a protective oxide film, which protects against corrosion. NP-2 pipe is capable of withstanding the influence of gaseous, liquid corrosive media, heating to a temperature of 850 ° C. Various types of processing (rolling, turning, bending) are possible due to high plasticity. The only drawback is an admixture of sulfur, which is able to form a sulfide film on the surface of nickel products, making the metal more brittle, brittle at high temperatures.

Manufacturing

Tubes and pipes of alloy NP-2 are produced in very different diameters. They can be supplied rolled into a bay or straight. The section can be in the form of a circle, a rectangle, an oval, an equilateral triangle, a square, and a convex regular polygon with a constant wall thickness along the entire length. The product of this type can be along the entire length with rounded corners. However, they are related to pipes, because the outer and inner cross-section has the same orientation and concentric shape. The surface can be polished or with an additional coating. At the request of the customer, the pipe can be threaded, bent, drilled, expanded or tapered, have flange cuffs or rings at the ends. Can be reduced to a cone for a more sealed and durable connection with the help of studs or bolts.

Application

Manufacture of capacitors. In the chemical industry, such pipes serve to transport aggressive substances, for example, acids and alkalis, since Ni in contact with them is not oxidized. The nickel tube NP-2 is also used in the production of hydrogen. Since Ni is resistant to steam, to acid corrosion — it is necessary in the manufacture of equipment for the chemical, food, paper industry, the production of steam condensers, injection needles.
