Stainless Steel Pipe Fittings
Butt Weld Fittings Reducing 90°Elbow
Application:
Butt weld long radius 90° Reducing Elbow LR is a kind of butt weld fittings.
There are two types of butt weld elbow, Butt weld 90 long radius elbow(90 LR elbow) and Butt weld 90 short radius elbow(90 SR elbow).The difference between them is the center to end distance.LR elbow center to end is 1.5 times of norminal pipe size,SR elbow center to end is equal to the norminal pipe size. Buttweld elbows below 24 inches are produced by cutting, heating and bending seam or seamless steel pipes; pipe elbows of larger sizes are made from welded pipes or steel plates.
Butt welding fittings are components used to connect pipes by welding.There are virous types of butt welding pipe fittings:elbow,tee,cross,reducer and cap etc.,
The key specifications for buttweld fittings are the ASME B16.9 (carbon and alloy fittings) and the MSS SP 43 (that integrates ASME B16.9 for stainless steel, duplex, and nickel alloy BW fittings).
Butt welding fittings can be used at high pressure piping connections.They are strong and have a long service life.Besides they are rather cheap to buy and deploy.

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.
