Types of ASI 317/317L SS buttWelded Elbow Pipe Fitting

Buttweld elbow fittings are used to change the direction of the fluid in the piping system. They have a long radius (LR) and a short radius (SR) type, and have different degrees covers to: 45 degree, 90 degree and 180 degree. The butt weld elbow dimensions can be specified as diameter (in NPS) and thickness according to ANSI B16.9, length in LR or SR. Buttweld tee fittings have a 90 degree branch and a straight line pipe that will provide a connection to install another device for the pipeline systems. They are available as equal tees and reducing tees. SS Buttweld pipe fittigs fittings can adjust the flow rate and speed. One end welded with a large diameter pipe and another end with a smaller OD pipe.

Long Radius Elbow (LR)

Long Radius Elbow (LR)

Long Radius Elbows (LR) are butt-welded stainless steel pipe fittings with a larger radius for enhanced fluid flow in the pipeline. They are generally employed to establish a 90 angle turn producing the minimum of friction and pressure drop.

Short Radius Elbow (SR)

Short Radius Elbow (SR)

A specific type of pipe fitting is Short Radius Elbows (SR) having compact radius equal to nominal size limitation for pipeline run with space constrains and tight turn. In given situations, they can be found in a sudden change of direction.

90-Degree Elbow

90-Degree Elbow

90-Degree Elbows are pipe fittings that alter the direction of fluid flow by ninety degrees thereby changing piping in a right turn. In plumbing and industrial installations, it is frequently used to direct edges or join two pipes at a 90 angle.

45-Degree Elbow

45-Degree Elbow

The forty five-degree elbows are not only pipe fittings but also aids in changing the flow direction by an angle of 45 degree, thus to give smoother and less abrupt change as compared with that provided through ninety degree elbow. It is usually used to reduce stress and turbulence caused by piping systems.

180-Degree Elbow

180-Degree Elbow

In pipelines, reversal of the direction in which fluid flows is done using 180- Degree Elbows—these are pipe fittings that create a U bend. Where a total change of movement is required, they are frequently used.

Frequently Asked Questions

What is the difference between long radius and short radius elbow fittings?
It is the long radius elbow fittings that have a longer curvature, thus giving smoother fl ow and minimized pressure drop. Short radius elbow fittings provide a smaller curvature radius and hence compactness but can lead to higher pressure drops.
What is the maximum pressure rating for stainless steel butt-welded elbow pipe fittings?
However, the maximum pressure rating relies on material grade, fitting size and design. It is always necessary to follow the manufacturer’s specifications and standards of industry for these particular pressure ratings.
Can stainless steel butt-welded elbow pipe fittings be used in high-temperature applications?
The answer is yes because stainless steel butt-welded elbow pipe fittings can resist high temperatures. The temperature specifications, however, may be dependent on the material grade and its use. It is therefore important to take into account the temperature restrictions from the manufacturer and refer back to industry standards.
