Fitwel Industries LLP is India's based leading global manufacturer, exporter and suppliers of 90 degree elbow, 45 degree elbow, 180 degree elbow, short radius elbow & long radius elbow pipe fittings in Mumbai & India. The most common dimensional standard for 45/90/180 degree elbows is ASME B16.9, B16.28 MSS-SP43/75 for sizes ranging from ½" to 72" (in all Schedules). In addition to standard size 90 degree elbows fittings, we can also offer larger sizes on customer request.
The function of an elbow fitting is to change direction or flow in a piping system. An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 90 Degree or 45 Degree angle. Hot forming is one of the most common manufacturing methods for manufacturing Elbows from pipes. The offered range finds their wide application in engineering and corporate sectors. Further, offered range can be customized as per specific requirements of our clients.
The Buttweld Elbow is where the two bones of the forearm – the radius on the thumb side of the arm and the ulna on the pinky finger side – meet the bone of the upper arm - the humerus. The lower end of the humerus flares out into two rounded protrusions called epicondyles, where muscles attach.
The Difference Between A Long Radius Elbow And A Short Radius Elbow. The long radius elbow refers to the outer diameter of the tube whose radius of curvature is equal to 1.5 times, that is, R = 1.5D. A short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = D.
The center to face distance of a long radius pipe elbow is always 1.5 times the nominal pipe size, whereas, for a short radius pipe elbow, the center to face distance is equal to the nominal pipe size.
Example:-
We are manufacturers and suppliers of Buttweld 45° Pipe Elbows that are popularly called as '45 Bends'. Joined to a pipe at a 45° angle, these pipes have a curve that produces a fine 45° directional flow of the inner fluid. Our Stainless Steel 45° Elbows are convenient to convey, are easy to handle, viable, reliable, and come with a good surface finish.
They are customizable as well with a long life span. We are exporters of ANSI B16.9 Buttweld 45° Elbows that are supplied in various sizes and threads to the paper, breweries, agricultural, electronics, and food processing industry.
We are a manufacturer, exporter & supplier of 90 Degree Elbows. 90 Degree Elbows have special quality finishing and duress for long life, high pressure, and zero defects.
The product differentiation is based on the premier finish of 90 Degree Elbows with minimum burr at the edge. The V shape formation for perfect welding and fabrication of the fittings in mega projects in the oil and gas industry for the long life of the product.
We manufacture 180-degree elbows in a huge quantity to fulfill the urgent demand of industries. We produce the best quality of 180 elbows by using the tested quality of raw materials, and we also follow all the National and International quality standards while manufacturing these 180-degree Elbows. Our elbow 180 degree helps to change the direction of pipes at 180 degrees since it usually results in low pressure. These elbow’s application is limited to the minimal deposition and low turbulence system. Our offered elbows are dimensionally accurate, efficient, and durable.

ASME B16.9 buttweld elbows are manufactured in a wide range of dimensions (combinations of outside diameter and wall thickness) to fit ASME B36.10 and ASME B36.19 carbon, alloy and stainless steel pipes of any size between 2 and 48 inches (and above).
Buttweld elbows below 24 inches in diameter are produced by cutting, heating and bending seamless steel pipes; pipe elbows of larger sizes are manufactured, instead, from welded pipes or steel plates.
The three most common types of elbows in piping are the 45, 90, and 180 degrees (or return elbow), as shown in the image:-
The elbow is divided into its radius of curvature and can be divided into a long radius elbow and a short radius elbow. The long radius elbow refers to the outer diameter of the tube whose radius of curvature is equal to 1.5 times, that is, R = 1.5D. A short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = D. Where D is the diameter of the elbow and R is the radius of curvature. Normal use of the length of the radius Sometimes to reduce the loss of resistance or elbow wear, the elbow with a larger bending radius will be used (in fact, it is not called elbow); when there is a limit on the installation position, a short radius elbow will be used.
When do you choose long radius elbows and short radius elbows? There are two types of pipe sizes for process installation, namely pipe outer diameter and nominal size. D, DN, refers to the nominal size of the pipe. It does not represent the inner diameter of the pipe or the outer diameter of the pipe. It is a nominal size designed and used. The elbow is the elbow, and the manufacturing method is divided into the push elbow, the extrusion elbow and the welded miter elbow. The structure length is 1.0D, 1.5D, 2.0D.
At present, there are two kinds of norms implemented in this area in China: metric and imperial. For example 1.5D steel seamless elbow, DN100 outer diameter ¢108 and ¢114.3, actual structural length L152, DN200 outer diameter ¢219 and ¢216.3, actual structural length L302. In use, long radius elbow (R = 15DN): in general, should be preferred; short radius elbow (R = 1.0DN): mostly used in applications where size is limited. Its high working pressure should not exceed 0.8 times the long radius elbow of the same specification.
Elbow (R=nDN): used to moderate the scouring and kinetic energy of the media at the bend, available to R=3DN, 6DN, 10DN, 20DN.According to different manufacturing methods, it is divided into push elbow, extrusion elbow and welded miter elbow.
Pushing elbows and extrusion elbows: Commonly used for welding mitered elbows on medium and small-sized pipes with strict media conditions: It is often used on large-sized pipes with moderate media conditions, and the bending radius is not to be less than its nominal diameter. 1.5 times. When the miter angle of the miter elbow is greater than 450, it should not be used on highly toxic, flammable medium pipes, or on pipes subjected to mechanical vibration, pressure pulsation, and alternating load due to temperature changes.
So how do we buy qualified elbows? Detecting the back arc of the elbow: Seamless elbow detection of the thickness of the back-arc is an important task. Many large pipe elbow manufacturers or strict engineering inspection of the back-arc is a must. It is related to the safety and stability of the pipeline operation.

Buttweld elbows 45 and 90 degrees can be manufactured in different ways, the main ones are the “mandrel process” and the “cold forming” (other methods are the elliptical forming and the double-seam welding method).
Everyone knows that both the seamless steel pipe and the seamless elbow are under pressure, that is, the pressure is very large when running. Under normal circumstances, the safety factor of the thickness of the seamless elbow designed and installed is about six times. For example, the 219*8 seamless elbow, the pipeline medium is ordinary water, the temperature is usually not higher than one hundred degrees Celsius, and the pressure required to blast such a seamless elbow is about 300 kg, that is to say, The pressure inside the pipeline needs to reach PN30, and the seamless elbow will be blasted, and the operating pressure of this elbow is probably about it. It is estimated that the maximum will not exceed PN6.4, which is generally around PN4.0, of course. With the corrosion of the pipeline, the seamless elbow will also be corroded to varying degrees. In order to ensure its safe operation, the necessity of overhaul is also great.
The current process of making seamless elbows will lead to the phenomenon of back-arc thinning. Under normal circumstances, the wall thickness of the mouth will be about two millimeters thinner than the back-arc. The common thickness and pressure are not thinner even if the back-arc is thinned. There will be too many safety hazards because the elbow has not been replaced until the elbow has a dangerous accident. But as a rigorous project, what is not the same, and the medium inside the pipeline is also responsible, not just water. There may be oil or other impurities, the temperature is high and the pressure is high, and the thickness of the back-arc as the weak place determines the life of the seamless elbow. Therefore, the importance of detecting the back-arc is naturally great. With the thickness gauge, read the thickness of a point at the elbow directly.
