The advantages of pushing elbows and the use of alloy elbows
Nov 18, 2017


Elbow is a kind of common pipe fittings. From the material point of view, there are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics, etc. Distinguish from connection mode, including direct welding, flange connection, hot melt connection, electrofusion joint, threaded connection and inserting type link, etc. If the elbow is classified according to the production method, there are welding elbow, stamping elbow, pushing elbow, casting elbow and so on.
 
The so-called pushing elbow is elbow which is formed through pushing, which has become a more used production process. Not only because of its production speed is faster, but also because it can achieve the batch production of elbow, and the quality of the elbow is also better.

In addition to pushing elbows, the alloy elbow is also a concern for all of the elbow products. It has a wide range of uses. For example, the bronze alloy elbow can be used in the water supply pipeline. The alloy elbow made of manganese steel has excellent functions of impact, extrusion, material wear and so on, so it is usually used in the pipeline such as concrete transportation pipeline, mud transportation pipeline and so on.

The high manganese steel alloy elbow is applied in the pipeline with strong fluid flow and strong impact. The alloy elbow of nickel steel material is a common product in the normal temperature transportation pipeline such as high concentration oxidizing acid. The martensite alloy elbow has high temperature strength, oxidation resistance and water vapor corrosion resistance at 650 ℃, but the weldability is poor. So it is suitable for use in high temperature water vapor transmission pipeline and water gas pipeline.

In the application of the alloy elbow, it must pay attention to its safety and application life. This aspect is usually related to the toughness, shock resistance and abrasive resistance of the lining. So in order to make the elbow more durable, its lining can be improved, so that the alloy elbow can play an important role in power, mining, metallurgy and other industries.
