Seamless Steel Elbow VS Welded Steel Elbow

Difference in appearance

The biggest difference between seamless elbows and welded elbows is the presence or absence of welds, but many weld elbows are now polished from the weld before leaving the factory, and many exporters sell such fake seamless elbows to customers. Even if the weld is polished, experienced customers can still distinguish it with the naked eye: the thickness of the seamless elbow is not uniform with respect to the thickness of the weld elbow. Currently, the false seamless elbow often appears in the area below the diameter DN600.

Differences in molding process

The process of using seamless steel pipes and welded steel pipes is the same process. The difference is that the welding elbows are made of sheet steel, by bending and different welding processes.

Differences in performance and usage

The seamless steel pipe elbow has better pressure bearing capacity and higher strength than the welded steel elbow. Therefore, it is widely used in high-voltage equipment, heat, boilers and other industries. Generally, the weld of the welded steel elbow is a weak point, and the quality affects the overall performance. In general, welded steel elbows can reduce working pressure by 20% compared to seamless steel elbows. This reliability is the main reason why people choose seamless steel elbows. In fact, all industrial pipes are finished with seamless pipe elbows because the elbows are subjected to extreme thermal, chemical and mechanical loads. In the aerospace, automotive and electronics industries with relatively low budgets, welding elbows are more popular, as are the working pressures on the pipeline.

Differences in available sizes

For most seamless steel elbow manufacturers in China, they produce original seamless pipe elbows with a maximum outer diameter of 24 inches and 609.6 mm. In contrast, welded steel pipe elbows do not have these limitations and can range in size from 1-1 / 2 inch 48.3mm to 100 inch 2540mm.

Different prices

Because the seamless manufacturing process is more complicated, the price is more expensive than the seamed elbow, and the seam is mainly made of steel plate (steel strip) for secondary welding, which is cheaper and more widely used.

How to Guarantee the Quality of Titanium Elbow?

We will do strictly inspection as below step:

• Visual the surface of 90 & 45 degree titanium elbow body.
• Check the marking: “ANSI B16.9 ASTM B363 GR.WPT2 SMLS 90 Deg LR Elbow 6 Inch Sch40S″.
• Measure the dimensions. Such as diameter, thickness, height from center to end.
• Test material chemical composition of titanium elbow.

How to Protect the Surface of Titanium Elbow?

• Hot Dipped Galvanized
• Cold Galvanized
• Black Primer
• PE Coated

Weight calculation of elbow

W=0.0387 * S( D – S ) * R / 1000
W = Weight (kg/piece).
S = Thickness Schedule.
D = Nominal Diameter.
R= Radius.

Note:

• Long Radius: R=1.5D
• Short Radius: R=1D
• R= Radius
• D= Outside Diameters

Manufacturing process of the pipe elbow

Mandrel method (Hot Forming)

• One of the most common Pipe Fittings Manufacturing Process for manufacturing Elbows Or Pipe Bends from the pipe is mandrel method which is kind of hot forming methods.
• In this method, the pipe is cut in pieces and push with the help of hydraulic ram. It is pushed over a die called “mandrel” which allows the pipe to expand and bend simultaneously.
• This method can be used to manufacture a wide range of the diameter of elbows or pipe bends
• 
• ELBOWS Or Pipe Bends Mandrel method

Extrusion Method

In cold Extrusion method, a pipe with the same diameter as finished product is pushed through a die and formed into its desired shape. Usually applied to stainless steel small to medium sizes elbows or pipe bends.

Extrusion Method

UO Method

UO method is used to manufacture medium size of the elbow, tee, and reducers. The plate is cut out into a specially designed shape, it is formed first into a U-shape using a die and then into an O-shape or tubular form using another die, that is why this method is known as UO method. Once the fittings formed in tumbler shaped it is welded from inside and outside of the closing seam. A cut plate is 1st from in U shape and then in O shape.

UO Method

Hot Forming Method

In a Hot Forming Die Bending method, a Pipe is heated to forming temperature & formed in the die with the specific shape, this process may be repeated as needed to obtain the required shape, size and wall thickness. Usually applied to thick-wall items that cannot be bent on a mandrel die.
