Butt weld long radius 90° Reducing Elbow LR is a kind of  butt weld fittings.

The 90-degree reducing elbow is also called the 90-degree reducing elbow, which is used to connect two steel pipes of different sizes for steering. The usual production process is to cut a 90-degree elbow blank with a standard pipe diameter, and then deform it in the mold with a hydraulic press, so that the two ends of the elbow have different sizes. After hydroforming, a shaping machine is used for shaping. 90-degree reducing elbow processing is a metal cold deformation processing method, it is one of the main methods of metal plastic processing (or pressure processing), and also belongs to the material forming engineering technology.

The advantages of the 90-degree reducing elbow manufacturing process are mainly manifested in the following aspects:   

1. Need to use elbow blank as raw material, no need to reopen the mold, saving mold cost and time, and at the same time, it can accept small batch orders from customers.

2. The blank of the reducing elbow is the elbow blank, so the workmanship is simple, the accuracy is easy to ensure, and the assembly and welding are convenient.

3. Due to the above two reasons, the manufacturing cycle can be shortened, and the cost of producing reducing elbows is greatly reduced.

As a high-quality pipe flange exporter in northern China, EATHU has a good price and quality in 90-degree reducing elbow products, and can produce 90-degree reducing elbows based on a small amount of project need. The quality and price of 90-degree reducing elbows are advantageous, please contact EATHU sales department to get the price list.
