Product Description
The Double Flanged 90° Bend is a type of pipe fitting that is designed to change the direction of fluid or gas flow in a pipeline by 90 degrees. It has flanges on both ends to enable easy connection to other pipes or equipment, and the double flanges provide added strength to the bend, making it suitable for high pressure or high temperature applications. This type of fitting is commonly used in industrial settings such as power generation plants, refineries, and chemical processing facilities.
Production Method
1.Cutting the raw material: The material used for a Double Flanged 90° Bend (usually carbon steel, stainless steel, or alloy steel) is cut to the required size and shape using a cutting machine.
2. Forming the bend: The cut material is then placed on a hydraulic press, and the bend is formed by applying pressure to bend it to a 90° angle.
3. Machining the flanges: The flanges are machined separately from the bend, using a lathe or milling machine, to ensure that they accurately match the size and shape of the adjacent pipes or equipment.
4. Welding: The bend and flanges are then welded together using various welding techniques, such as TIG, MIG, or Stick welding, to create a strong and secure connection.
5. Surface treatment: The finished product is then subjected to surface treatment, such as sandblasting, to remove any rough edges or imperfections and create a smooth surface.
6. Testing: The final step involves testing the bend for any leaks or defects, using various testing methods such as hydrostatic testing or ultrasonic testing. This ensures that the bend meets the required standards and specifications before it is shipped to the customer.
