Elbow

Share to:
Name:Elbow
SIZE: 1/2" - 24" DN15- DN300
STANDARD: ASTM A234 WPB,
THICKNESS: SCH20, SCH40,STD,SCH80,XS, SCH160
USED FOR OIL & GAS PIPE LINE,
Quantity:

An elbow is a pipe fitting installed between two lengths of pipe, which can change direction, usually at an angle of 180° or 90°, although it can also be made into a 45° elbow. The end can be processed into butt welding (SW) or sleeve welding (SW).


Most elbows have short radius or long radius. When the two ends are different in size, the accessory is called a reducing elbow or a reducing elbow.
The long radius elbow (LR 90 elbow or LR 45 elbow) will have 1.5 times the pipe size. Therefore, the bending radius of a 6-inch LR 90 is 1.5 x the nominal pipe size. The elbow diameter of the short radius elbow (SR45 or SR90) is equal to the joint size, so the elbow radius of 6" SR 45 is the nominal pipe size of 6".


90°Elbow


Elbows are categorized based on various design features as below:

Long radius (LR) elbows are also called LR elbows-meaning that the radius is 1.5 times the pipe diameter
L / R 45° elbow: Long radius 45° elbow can change the direction by 45°.
L/R 90° elbow: 90° long radius elbow changes the direction by 90°.
Left/right 180° elbow: The long radius 180° recurve allows complete reverse flow.
Short radius (SR) elbows are also called SR elbows, which means that the radius is 1.0 times the pipe diameter
Short radius 45° elbow: Short radius 45° elbow can change the direction by 45 degrees.
Short radius 90° elbow: The short radius 90° elbow is the same as LR90, except that the size from the end of the elbow to the centerline is 1 x NPS.
Short radius 180° elbow: short radius 180° bend allows complete reverse flow


Buttweld fittings applications:
Pipe fittings are defined as parts used to change the direction, branch or change the diameter of the pipe in the pipe system, and are mechanically connected to the system. There are many different types of fittings, which are the same as pipes in size and schedule.


Buttweld fittings advantage:

Welding the fitting to the pipe means it is permanently leakproof

The continuous metal structure formed between the pipes and fittings adds strength to the system
The smooth inner surface and gradual change in direction reduce pressure loss and turbulence, and minimize corrosion and erosion
Minimum space occupied by welding system


90 Degree long radius elbow

Use these elbows to make a 90° adjustment in the path of the stainless steel pipe.

Schedule 10 fittings are an economical alternative to low pressure applications.

Schedule 40 fittings have thicker walls and are suitable for high pressure applications.

304L stainless steel is a chromium-nickel material with very good corrosion resistance.

316L stainless steel has a higher nickel content and molybdenum content, which has higher corrosion resistance. Stainless steel threadless pipes suitable for air, water, oil and natural gas.




The 180-degree long radius elbow is used to connect pipes of different diameters and is widely used in various chemicals, construction industries, papermaking, cement and shipyards.


We use advanced production equipment to make 180-degree long radius elbows, which can not only improve product quality, but also save raw materials.
