Butt Weld Fittings
Butt Weld Fittings Manufactures
Stainless steel Butt weld pipe fittings and butt weld tube fittings are available in multiple shapes (elbows, tees, reducers, crosses, caps, stub ends), material grades (carbon, high-yield carbon, low-alloy, stainless, duplex, and nickel alloys), and dimensions (2 to 24 inches in seamless execution, and welded for larger pipe sizes).S Nomi & Co is the leading Stainless steel butt weld pipe, tube fittings Suppliers in Kolkata, West Bengal, Bihar, Odisha, Jharkhand.
The key specifications for buttweld fittings are the ASME B16.9 (carbon and alloy fittings) and the MSS SP 43 (that integrates ASME B16.9 for stainless steel, duplex, and nickel alloy BW fittings). S nomi is the renowned manufacturers of Butt Weld Fittings in Kolkata, West Bengal, Bihar, Odisha, Jharkhand.
Butt welding fittings have the following benefits
- allow strong, and leak-proof, piping connections
- minimize pressure drops and the turbulence inside the pipeline
- have a long service life
- are rather cheap to purchase and deploy
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:
Some special types of pipe elbows are:
- reducing elbow: a pipe connector with an inlet and an outlet in two different bore sizes is used instead of the combination of a standard elbow and concentric reducer.
- mitered elbow: large size elbow assembled by joining steel plates
SHORT VS LONG RADIUS ELBOW
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:
- For a 4 inches long radius (LR) butt weld elbow, the center to face distance is 4 x 25.4 x 1.5 = 152.4 mm;
- For a short radius butt weld elbow, the center to face distance is instead 4 x 25.4 x 1 = 101.6 mm. Short radius pipe elbows are available only for the 90 and 180-degree configuration (and not for the 45 degrees); instead, long radius elbows are available for all degrees
PIPE ELBOW MANUFACTURING PROCESS
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).
