Steel Pipe Important Materials, Widely Used

Aug 09, 2017

1, the concept of Steel Pipe: Steel Pipe is ingot, billet or Steel Pipe through the pressure processing we need to make a variety of shapes, sizes and performance of the material.

According to the different shapes of the Steel Pipe, the Steel Pipe is generally divided into four categories: profiles, plates, pipes and metal products. In order to facilitate the production of Steel Pipe products, the Steel Pipe is widely used in the construction of Steel Pipe products. Supply and do a good job in management and management work, but also divided into heavy rail, light rail, large Steel Pipe, medium-sized Steel Pipe, small Steel Pipe, Steel Pipe cold-formed Steel Pipe, high-quality Steel Pipe, wire, Steel Pipe plate, thin Steel Pipe, electrical silicon Steel Pipe, , Seamless Steel Pipe pipe Steel Pipe, welded Steel Pipe pipe, metal products and other varieties.

2, Steel Pipe production methods

Most of the Steel Pipe processing is Steel Pipe through the pressure processing, so that the processing of Steel Pipe (billets, ingots, etc.) plastic deformation. According to the Steel Pipe processing temperature is not the same as the cold and cold processing of two kinds of hot processing. The main processing methods of Steel Pipe are:

Rolling: The Steel Pipe metal blank through a pair of rotating roll gap (various shapes), due to the compression of the roll material to reduce the cross-section, the length of the increase in pressure processing methods, which is the most commonly used production of Steel Pipe production methods, To produce Steel Pipe profiles, sheet metal, pipe. Min cold rolling, hot rolling.

Forged Steel Pipe: the use of forging hammer reciprocating impact or press the pressure to change the blank to our desired shape and size of a pressure processing methods. Generally divided into free forging and die forging, often used for the production of large profiles, billet and other cross-section Steel Pipe material larger material.

Pulling Steel Pipe: is the rolling of the metal blank (type, tube, products, etc.) through the die hole to reduce the cross-section to increase the length of the processing methods are mostly used for cold processing.

Squeeze: the Steel Pipe will be placed in a tightly pressed metal extrusion, one end of the pressure, the metal from the specified die hole out to get the same shape and size of the finished product processing methods, and more for the production of non-ferrous metals Steel Pipe

First, ferrous metals, Steel Pipe and non-ferrous metals Before introducing the classification of Steel Pipe, please briefly introduce the basic concepts of ferrous metals, Steel Pipe and non-ferrous metals.

1, ferrous metal is iron and iron alloy. Such as Steel Pipe, pig iron, iron alloy, cast iron and so on. Steel Pipe and pig iron are based on iron and Steel Pipe, carbon as the main elements of the alloy, collectively referred to as iron-carbon alloy.

Pig iron is the iron ore into the blast furnace smelting products, mainly used for Steel Pipe and Steel Pipe manufacturing castings. The cast iron into the melting furnace in the melting, that is, cast iron (liquid), the cast iron cast into cast Steel Pipe, this cast iron is called cast iron.

Ferroalloy is composed of iron and silicon, manganese, chromium, titanium and other elements of the alloy, ferroalloy is one of the raw materials for Steel Pipe, Steel Pipe Steel Pipe in Steel Pipe when the Steel Pipe deoxidizer and alloying elements used.

2, the Steel Pipe with iron into the Steel Pipe furnace according to a certain process smelting, that is, Steel Pipe. Steel Pipe products are Steel Pipe ingot, continuous casting and straight Steel Pipe cast into a variety of Steel Pipe castings and so on. Usually referred to the Steel Pipe, generally refers to the rolling into a variety of Steel Pipe Steel Pipe. Steel Pipe Steel Pipe is black metal but Steel Pipe is not exactly equal to ferrous metal.

3, Steel Pipe nonferrous metals, also known as non-ferrous metals, refers to the black metal and other metals and alloys, such as copper, tin, lead, zinc, aluminum and brass, bronze, aluminum alloy and bearing alloys. In addition, the industry also uses chromium, nickel, manganese, molybdenum, cobalt Steel Pipe, vanadium, tungsten, titanium, etc. These metals are mainly used as alloy additives to improve the performance of metals, including tungsten, Steel Pipe, molybdenum, The carbide used for the tool. Above these non-ferrous metals are known as industrial metals, Steel Pipe in addition to precious metals: platinum, gold, silver and other rare metals, including radioactive uranium, radium and other Steel Pipe.
