Stainless Steel Concentric Reducer is manufactured according to ASME B16.9, American standard for buttweld pipe fittings.

Stainless steel buttweld fittings is known for the high strength, excellent corrosion withstand and long service life. They are suit for air, water, oil and natural gas applications. Schedule of buttweld fittings refers to the wall thickness, higher schedule pipe fittings can bear higher pressure. Sch 10s, Sch 40 and Sch 80 pipe reducer is more common.

Stainless Steel pipe reducer can be divided into concentric reducer and eccentric reducer.

Concentric reducer is symmetrical, the center of two end are on the same line, while eccentric reducer is not symmetrical and usually used in the vertical pipeline.

According to the manufacturer technique, it also divided into seamless reducer and welded reducer. Large diameter reducer often is welded in order to save cost.

Based on their materials, there are stainless steel reducer, carbon steel reducer or alloy steel reducer.

Zizi manufacture top class 45 degree, 90 degree, 180° of 304 & 316 stainless steel pipe elbow in long radius and short radius version.

Stainless Steel pipe elbow pipe fittings changes the direction of pipeline in a certain degree. 45° elbow, 90° elbow and 180° elbow is very commonly used in industry. And some special degree elbow such as 60 ° elbow is also available for customer. All of them are available long radius version, and generally speaking, short only 90 degree and 180 degree elbows has short radius version.

We supply best quality 4″ STD ASTM A403 WP304 180 Degree elbow with attractive price for customers.

Difference between Long Radius Elbow & Short R Elbow

180° LR Elbow & SR Elbow

LR & SR elbow have the same inner and outer diameter, angle and schedule. The only difference is their center to face distance.

Center to face refers to the center line of one end to the opposite face. LR elbow center to face distance is 1.5 times the NPS (R=1.5D), SR elbow is equal to the NPS (R=1D).

Short radius elbow is suitable for tight areas, while long radius 180 degree elbow is better when it is scoured and worn.

Inspection of Buttweld Fittings

The inspection is operated according to ASME B16.9

Check the surface

1. Marking includes size, material, standard and Lot No. Be sure they are correct and clear.
2. Touch and visual check the surface to ensure it is smooth and even.

Measure the size

1. Measure diameter, length, radius.
2. Confirm the sizes are in tolerance.

Tolerance for Lap Joint Stub End

Approve third party inspection

1. Third parties such as BV, SGS, LR, DNV, ABS.
2. Offer stamped Mill Test Certificate.

Advantages of Lap Joint Stub End

There are two main advantages for using stub end with flanges:

1. Reduce the total cost.

With using stub end, the material of lap joint flange can be lower grades than pipe lines. For example, in a stainless steel pipe line, you can use a stainless steel stub end and a carbon steel lap joint flange instead of using a full stainless steel weld neck flange to saving the cost.

2. Speeds up the installation process.

Type A stub end can help simplify and align the bolt holes of flanges. The usage of stub end is becoming prevalent both in low pressure applications and high pressure applications.

90° Steel Pipe Elbow is the most commonly used elbow type in pipe system with the function to change the direction of fluid in 90 degree. It connects pipes with same or different diameter.

This kind of elbow is classified by angle, and 45 degree elbow and 180 elbow is also very popular. And steel pipe elbow is also available in 60 degree, 30 degree and other special angle according to practical needs.

Except the angle, steel pipe elbows can be divided into diverse types based on different factors. Here we will use 90 degree elbow to show how they classified according to other factors.

How to Classify 90 Degree Pipe Elbow

We mainly divide steel pipe elbows according to

1. Angle
2. Radius
3. Connection
4. Material

Since our focus is on 90 degree steel pipe elbow, we will discuss 2, 3 and 4 in details.

Long Radius Elbow and Short Radius Elbow

Radius refers to curvature radius of 90° Steel Pipe Elbow. It typically has long radius and short radius two types. It is a necessary elements to descrip buttweld elbows.

Long Radius Elbow and Short Radius Elbow

• Long radius 90 Degree Elbow

In contrast, long radius 90° steel pipe elbow is more common, the radius is 1.5 times of pipe diameter (R=1.5D). It is usually used in high pressure or fast flow rate pipelines.

Generally speaking, if the elbow radius is not mentioned, we usually regard it as long radius elbow.

When the radius larger than 1.5D, they will be expressed as R=3D, 5D, 10D……even someone also call them long radius elbow.

• Short Radius 90 Degree Elbow

It means the radius is equal to the pipe diameter ( R=1D). Short radius elbow also looks shorter than long radius elbow, and it is applied in low pressure fluid pipe system or where elbow conditions are limited.

Connections Types of Steel Pipe Elbow

According to the connection way, there are Buttweld Elbow, Socket Weld Elbow and Threaded Elbow.

Buttweld 90° Elbow

Butt weld elbow is directly welded with pipes. For the purpose of easy welding, its end usually is beveled, but also available in plain end. Based on the produce process, it also has seamless and welded types.

The advantages of buttweld 90° steel pipe elbow are it has large dimension ranges and strong structure as well as withstand higher pressure than other connection types.

Socket Weld 90° Elbow

Socket weld elbow has a trapezoidal area at the end for inserting the pipe, and then pipes and socket weld elbow will be fillet welded together.

The advantages of socket weld 90° steel pipe elbow are it is free to align and beveled for welding, leak-proof, and withstand to high pressure and temperature.

Both equal tee and reducing tee have three branches that usually is T-shaped, they provide 90 degree branches and change fluid direction. ASME B16.9 Buttweld tees are widely used in pipe convey. They are very common in industrial applications such as oil and gas transmissions, water treatment system, power station, chemical industry and engineering.

Zizi is steel pipe fittings manufacturer and offers buttweld fittings equal tee and reducing tee in different dimensions and materials according ASME B16.9.

What is ASME B16.9 Buttweld Tees?

ASME B16.9 is manufacture standard for Factory-Made Wrought Buttwelding Fittings. Put simply it is specification for butt weld fittings.

Buttweld pipe tee connected by butt welding, which is stable than other weld type and can withstand higher pressure. Fittings ends need preparation before welding, so the end can be plain or beveled.

Diameter of ASME B16.9 tees is from 1/2” to 80” (DN15 to DN2000), wall thickness is specified in schedule 10S, 20, STD, 40, XS, 80, 120, 140, 160, and XXS.

What’s more, based on the production process, they are also can be divided into seamless tee and welded tee.

Buttweld Equal Tee & Reducing TEE

How many Types of Buttweld Tees?

How to Calculate the Weight of Steel Bends?

Weight formula: 0.0433 x (D-T) x T x R x θ / 100000 + L

• D = Outside Diameter
• T = Thickness
• R = Bend Radius
• θ = Bend Angle
• L =  Weight of Double Sides Straight Length

Differences Between Pipe Elbow and Pipe Bend

• Radius

The maximum radius of pipe elbow is 1.5D, which means radius is 1.5 times of diameter. While minimum radius of pipe bend is 1.5D.

Because of the larger radius, stainless steel 3D bend offers more smooth direction change than elbows.

• Length

The straight length of pipe elbow is shorter than pipe bends.

Straight length of stainless steel 3D bends are usually between 300mm to 1500mm.
