Sk Tube Corporation , an ISO 9001:2015 Certified Company, is a top producer and supplier of elbows with both short and long radii. We provide our materials in accordance with international standards and with full certifications. We manufacture elbows made of stainless steel, carbon steel, alloy steel, and exotic alloys including monel, inconel, and hastaloy. For a variety of diameters, we are able to provide elbows up to 48′′ in length with wall thicknesses ranging from 1.5 mm to 40 mm.
A 90°, 45°, or 180° angle is typically used to join two lengths of pipes and change the direction of flow in the pipe. An elbow is a type of pipe fitting used for this purpose. Elbows, also called bends, come in a variety of materials, including duplex, cupro nickel, carbon steel, alloy steel, stainless steel, and nickel alloys.
90° elbows, also referred to as 90° bends, are produced in two sizes: SR (Short Radius) and LR (Long Radius). LR (Long Radius) elbows are the most common type of 45° elbows.
While the short radius elbows have a center to end distance equal to the NPS in inches (R=1.0D), the long radius elbows have a center to end distance 1.5 times the NPS in inches (R=1.5D).=When space is available and flow is more important, long radius elbows are utilized; short radius elbows are typically utilized in cramped spaces. Additionally, we are able to produce and provide elbows made of carbon steel and stainless steel with non-standard size angles like 60°, 100°, 120°, or 150°.
The ends can be threaded (typically female), socketed, or machined for butt welding, among other options. The fitting is referred to as a reducing elbow or reducer elbow when the two ends have different sizes.
We produce and supply high-quality stainless steel elbows, duplex elbows, carbon steel elbows, long radius elbows, short radius elbows, and fabricated stainless steel elbows. Our goods are supplied to clients in a number of industries, including engineering, petrochemical, chemical, pharmaceutical, and power.
