Description
An elbow is a fitting that changes the direction of a run. According to the angle, there are three kinds of most commonly used: 45 ° and 90 ° 180 °. In addition, according to the needs of the project, there are other abnormal angle elbows such as 60 °. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics, etc.
The methods of connection with pipes include direct welding, flange connection, hot melt connection, electric melt connection, threaded connection, socket connection, etc.
It is not allowed to weld two 45 degree elbows into 90 degree elbows for use, because elbows are the concentration area of stress on pipes, and most of the stress of expansion and cooling deformation are released at elbows. In addition, the weld itself should be a weak link, fatigue deformation is easy to cause crack damage, and a great hidden danger is buried.
Characteristic
If a 90 ° elbow is reused in a through wall drain pipe, it will cause a lot of noise when the drop is large and the water flow is too large. It also cause a lot of impact force on the elbow when the water flow is large or mixed with foreign matters, which may lead to the rupture of the elbow.When the 45 degree elbow is used, a certain slope is formed at the corner, which plays a role of buffer.
Even when the water flow is very large and mixed with foreign matters, the impact on the pipe wall at the elbow will be greatly reduced.Stainless steel 45 ° elbow is a kind of pipe fittings, which can change the flow direction of liquid or gas in the pipe system.
The common production processes of stainless steel elbow are pushing, pressing, forging and casting. Our factory has many years of production experience. The elbow products are of good quality and even thickness. There are 1D elbows and 1.5D elbows in conventional production.
Advantage and Application
The 45 degree thread stainless steel seamless elbow produced by our factory is mostly produced according to gb12459-2005 slotted elbow according to gb13401-2005.
There are many standards such as American Standard ASME b16.9, as well as ship standard, electric standard, water standard, German standard and other standards, which can be produced.
When quoting the price of stainless steel elbow, it is necessary to accurately inform the pipe pressure used, or directly inform the elbow wall thickness, so as to quote the accurate price.
Generally speaking, different pressure grades such as sch10s and sch20s represent different thickness of elbow, which can be referred to American standard pressure grade wall thickness table.
