Characteristics and application of carbon steel elbow


First, the classification of elbows

In a piping system, an elbow is a pipe that changes the direction of the pipe.

1, according to the angle, there are 45 ° and 90 ° 180 ° three most commonly used, in addition to the engineering needs also include 60 ° and other abnormal angle elbow.

2. The materials of the elbow are cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metals and plastics.

3. The way to connect with the pipe is: direct welding (the most common way) flange joint, threaded joint and socket type joint.

4, according to the production process can be divided into: welding elbows, stamping elbows, casting elbows and so on.

Second, the characteristics and application range of carbon steel elbow

Carbon steel elbow material is carbon steel elbow called carbon steel elbow. The carbon steel elbow is the connection of two large diameter pipes, usually two elbow pieces plus a number of fastening bolts. The carbon steel elbow is an elbow made of carbon steel. Low-carbon steel has good plasticity and low strength. When a proper amount of carbon is added, it becomes hard and the plasticity is reduced. Elbow joints may need to withstand high tensile, compressive, torsional, and shear strength. Carbon steel elbows are a good choice.

The rigidity of the carbon steel elbow is poor, and it is suitable for the occasion of the pressure p≤4MPa; the butt weld elbow is also called the high neck elbow, and the rigidity is large, which is suitable for occasions with high pressure temperature. There are three types of elbow sealing surfaces: flat sealing surface, suitable for occasions where pressure is not high and medium is non-toxic; concave and convex sealing surface is suitable for occasions with higher pressure; gutter sealing surface is suitable for flammable and explosive , toxic media and high pressure occasions.

The carbon steel elbow is relatively simple to manufacture, and is mainly suitable for piping systems with corrosive media; the elbow and the flat welding ring can be made of different materials to reduce the cost of the elbow and improve the performance. The elbow sealing surface has a convex surface, a concave surface, and a groove surface.

Carbon steel elbows are widely distributed in industries with severe wear such as thermal power, steel, smelting, cement, machinery, coal, mining, chemicals, ports and terminals. Carbon steel elbows fully demonstrate good performance advantages and ensure important performance and operational contributions.

Third, carbon steel elbow wear factor analysis

The wear of carbon steel elbows has always been a factor affecting safe and civilized production. With the continuous development of science and technology, materials are also constantly innovating, and successively cast stone, cast steel, alloy, centrifugal cast composite ceramics and other materials. Among them, the pipeline-lined alumina ceramics have high wear resistance, high hardness, oxidation resistance, corrosion resistance and high resistance to high and low temperature strength. Most of the imported equipments are made of this carbon steel elbow.
