Elbow is a common connection pipe in the installation of water heating. It is used for the connection at the bend of the pipe and to change the direction of the pipe. It is used to connect two pipes with the same or different nominal diameters, so that the pipes can make turns of 90 °, 45 °, 180 ° and various degrees. It is divided into right angle bend, stamping elbow, pressing elbow, mechanism elbow, welding elbow, etc. Bending radius less than or equal to 1.5 times of pipe diameter is elbow, and greater than 1.5 times of pipe diameter is elbow. Generally, 90 degree elbow is mainly used for the connection of pipeline. Make two pipes of the same diameter of the pipeline make a 90 degree turn.

90 degree elbow is a general term for a variety of elbows. Its material is very many. Common are carbon steel, manganese steel and nickel steel. The 90 degree elbow is widely used. The common bronze 90 degree elbow is mainly from the common tap water pipe, but later a lot of tap water pipes gradually changed to stainless steel elbow. The elbow made of manganese steel can bear more pressure and bearing capacity. It has strong corrosion resistance and is usually used between pipelines for transportation. Socket elbow is a kind of high-pressure elbow pipe connecting fitting, which is mainly formed by forging blank of round steel or ingot and then processed by lathe. It is a kind of forged socket pipe fittings. Common standards include GB / t14383-93, GB / t14383-2008, American Standard ASME B16.11, petrochemical standard sh3410, Ministry of chemical industry standard Hg / t21634, etc.

The commonly used order specification is dn15-dn50. If there are out of the scope of the specification, you can communicate with the customer about the design and processing of drawings. The difference between a 45 degree elbow and a 90 degree elbow is that a 90 degree elbow forms a right angle, while a 45 degree elbow is an obtuse angle. In application, two 45 degree elbows can not be welded into 90 degree elbows for use, because elbows are stress concentration areas 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, and fatigue deformation will soon cause cracking damage and loss.


1,  The carbon steel elbow does not need the tube blank as the material, the blanking is simple, the accuracy is easy, the assembly welding is convenient, especially suitable for the field processing of large elbow.

2,  There are two main manufacturing processes: Hot push forming and stamping forming. Stamping elbow is an earlier forming process applied to mass production of seamless elbow.

3,  It has been replaced by hot pushing or other forming processes in the production of common elbow specifications.

4,  It can only be used when there are special requirements for some elbow specifications due to small production quantity, too thick or too thin wall thickness.


Carbon steel socket welded 90 degree elbow is mainly used in petrochemical power, aerospace, military industry, fire protection, metallurgy, shipbuilding, gas, nuclear power, environmental protection and other departments and fields requiring high pressure and precision size.
