Return Pickled Seamless Buttweld

The Stainless Steel 180 Degree Elbow is mainly used in a connecting pipe for the pipe installation for the connection of the pipeline of the pipe, connecting two of the same or different nominal diameter pipe, making the conduit etc. A 180-degree turn Stainless steel 180-degree elbow is mainly distinguished on different materials from the carbon steel elbow, and the chemical composition contained in the elbow is not rusted for a long time, and it will not be corroded.

Return Pickled Seamless Buttweld FAQs

Q 1. What Are the Using Characteristics of Return (180 Degree Elbow)?
A.

(1)When the medium in the pipeline needs to flow in the opposite direction and the layout space is insufficient, the client can use a 180-degree elbow to solve it;

(2)If a 90-degree elbow is used, a certain short pipe is generally required in the middle. The cost for welding will be increased and the stress resistance is greater.

(3)The 180-degree elbow is used a lot in the evaporator of the ammonia refrigeration system.

Q 2. What is Long Radius or Short Radius for One Elbow?
A.

Long radius elbow refers to its radius of curvature equal to 1.5 times the outside diameter of the tube, that is R=1.5D. Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D.
