Stainless Steel Elbow VS Stainless Steel Joint

Many people don't know how to distinguish stainless steel elbows from joints, and sometimes they confuse them. In fact, stainless steel elbow is one of the stainless steel joints. So how do you distinguish them? Below, baowi steel will talk about the difference between stainless steel elbow and stainless steel joint.

Stainless steel elbow is a kind of connecting pipe fitting commonly used in pipeline installation, which is used to connect the pipeline bend and change the direction of the pipeline, so it is called elbow. According to the needs of the installation site, there are different angles and names: 90 elbow, right-angle elbow, love elbow, stamping elbow, pressing elbow, machine elbow, welding elbow, etc.

Folding bend radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and more than 1.5 times of pipe diameter belongs to elbow purpose: connecting two pipes with the same or different nominal diameters, so that the pipeline can turn 90, 45, 180 and various degrees.

Stainless steel joints are mainly used to connect various pipes into pipes. With the continuous development of economic construction of stainless steel joints, stainless steel joints are widely used. Through the analysis of corrosion resistance of passivation layer on stainless steel surface, combined with the application of advanced production technology and equipment, high-quality stainless steel fixtures are produced to meet the needs of production and life and fill the gap in China.

The common stainless steel elbow is actually one of the stainless steel joints. It is a kind of connecting pipe fitting commonly used in pipeline installation, which is used to connect the pipeline bend and change the direction of the pipeline, so it is called elbow. According to the needs of the installation site, there are different angles and names: 90 elbow, right-angle elbow, love elbow, stamping elbow, pressing elbow, machine elbow, welding elbow+and so on. Folding bend radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and more than 1.5 times of pipe diameter belongs to elbow purpose: connecting two pipes with the same or different nominal diameters, so that the pipeline can turn 90, 45, 180 and various degrees.

The elbow (joint) formed by stainless steel stamping is a forming process that has been used for mass production of seamless elbows. It has been replaced by hot pushing or other forming processes in the production of elbows with common specifications, and it is still used when the products have special requirements. The tube blank with the same outer diameter as the elbow is used in the stamping forming of the elbow, and it is directly pressed in the mold by using a press. However, in some specifications of elbows, the production quantity is small, the wall thickness is too thick or too thin. Before stamping, the tube blank is placed on the lower die, the inner core and the end die are put into the tube blank, and the upper die moves downward to start pressing, and the elbow is formed through the constraint of the outer die and the support of the inner die. Stamping stainless steel elbows can be divided into two types: cold stamping and hot stamping. Usually, cold stamping or hot stamping is selected according to material properties and equipment capacity.

Compared with the hot push process, the appearance quality of stamping is not as good as the former; The outer arc of the stamping elbow is in tension during forming, and there is no extra metal in other parts to compensate, so the wall thickness of the outer arc is reduced by about 10%. However, because it is suitable for single-piece production and low cost, stamping elbow technology is mostly used for the manufacture of small batch and thick-walled elbows.

In addition to stainless steel elbow, stainless steel joints include stainless steel tee, stainless steel four-way, stainless steel large and small heads, and (concentric) eccentric reducer, which all play an important role in pipeline installation.

The above is the relevant answer to how to distinguish stainless steel elbow from stainless steel joint. Baowi steel focuses on the design, development and production of stainless steel piping system, and rapidly applies the piping system to the industrial field.
