Flange forming machine

Types of flange forming machines

Flanges are used to create a tight joint between pipes and to accommodate pipe fit-ups and the expansion of materials. An edge that is created at right angles to the plane of the material for the purpose of welding is called a flange. There are many types of flanges, including the welding neck flange, which is used when the angle between the flange and pipe needs to be in accordance with a particular requirement. The broad types of flange forming machines can be categorized according to the types of flanges they make:

• Welding Neck Flange Forming Machine: As mentioned above, welding neck flanges have pipes that are welded to them. These types of flanges are widely used in high-stress areas. They can take high pressure and temperature changes. The flange forming machines for these types of flanges will help create the neck that is to be welded to the other parts of the material.
• Slip-On Flange Forming Machine: The slip-on flange is one of the most used flanges in the industry. When the flange is slipped onto the pipe, it is then welded onto the top and bottom. The flange machine for this type of flange would help create a welded neck, which is generally used for low-pressure systems. However, they can also be used for high-pressure ones if the proper material and methods are used. Machine operators should know the difference.
• Custom Flange Forming Machine: Custom-made flanges are made according to the buyer's specifications. The types of flange forming machines for custom flanges will depend on the custom design that is required. Custom flanges can include special-sized rings, reliefs, and other distinct structural features.
• Universal CNC Flange Forming Machine: This machine is one of the most advanced forming machines that has a numerical control system. CNC machines use computer programs to precisely shape and cut materials. Universal machines can form various types of flanges, including welding necks, slip-ons, blinds, etc. These machines typically have a 4-5 sets of rollers and a CNC control panel for easy operation. The rollers are made of Hardened Steel with HRC 45-55 to ensure durability and strength.
• Hydraulic Flange Forming Machine: A hydraulic forming machine uses specific technology to produce flanges at a higher rate than machines with different types of forming methods. The machine uses rotary and hydraulic technology to form flanges with high cutting speeds and precision. They can make various flange types, including welding neck flanges, slip-on flanges, and custom ones.
• Impeller Flange Forming Machine: This machine will form the flange for an impeller. The impellers are typically used for pumps, and they help to increase the pressure and flow of fluids within the pump system.

Specification and Maintenance

• Machine Power:

  A flange-forming machine usually requires a specific power supply to run efficiently. This power is often expressed in kilowatts (kW) or horsepower (HP). The machine's power determines how thick and strong the metal it can work with is. For example, a machine with a higher power rating can handle tougher metal material. This means it can make flanges from very sturdy, heavy metal without any problems.

• Flange Forming Modes:

  Machines for forming flanges have different ways they can work. Two common methods are hydraulic and mechanical operation. Hydraulic machines use fluid pressure to shape the metal. Mechanical ones rely on electrical motors and gears. Each one has its own benefits, like hydraualics usually handling larger sizes easily.

• Mold Types:

  To make different styles of metal flanges, machines use various molds or dies. A mold called a punch dies sets the metal into a certain shape when pressed. Another type, splitter dies, cuts the metal to create evenness and accuracy. Each mold allows the flange-forming machine to produce specific, diverse shapes of flanges from the metal.

• Machine Size:

  Flange forming machines are made in different sizes to accommodate various flange types and dimensions. The size is often denoted as 'Length * Width * Height'. It is also indicated in terms of weight. Larger machines are usually heavier and need more space to set up.

It is also crucial to conduct regular maintenance for the machines to keep them functioning for a long time. Users can consider the following care and maintenance tips:

• Make a program for periodic inspections. Check vital parts like motors, bearings, gears, and hydraulic systems. Look for signs of wear, damage, or leaks.
• Implement a lubricating schedule. Apply appropriate lubricants to moving components as per machine manuals. This reduces friction and keeps parts from wearing quickly.
• Ensure hydraulic fluids are clean and of the correct type. Replace and flush systems if contaminated. Maintain proper fluid levels.
• Maintain electrical connections. Check wires for corrosion or loosening and ensure reliable secure insulation.
• Use cooling systems to avoid overheating. Let machines cool down occasionally and clean cooling fans or radiators to prevent blockages.
• Educate operators on correct machine usage and maintenance. Training workers who run machines extends lifespan through proper handling.

Application scenarios of flange forming machines

Flange forming machines are used in manufacturing industries and workshops to make flanges for the end of pipes. They are commonly seen in the following places:

• Oil and gas industry: Machines used to make oil pipeline flanges and valves must be sufficiently strong to withstand high pressure.
• Chemical factories: Chemical factories make pipes and tubes with chemical-resistant materials. They also use flange forming machines.
• Water transmission systems: In municipal or urban infrastructure, they help to create secure joints in pipes used for water supply or drainage systems.
• HVAC systems: In HVAC systems, they allow for the fabrication of custom duct flanges to ensure proper connections and fittings between duct sections, diffusers, and bulkheads.
• Automotive industry: Automotive industries use compact flange forming machines to produce flanges for connecting tubes and giving additional strength to joints.
• Pneumatics and hydraulics: Flange forming machines help to create flanged connections in hydraulic and pneumatic systems, ensuring secure joints for pipes carrying fluids and gases under pressure.
• Marine and shipbuilding: The flange forming machine makes injected ship pipes that provide connections for marine equipment and vessels.
• Agriculture: Agriculture uses compact flange forming machines to produce flanges for connecting irrigation pipes and drip systems, ensuring reliable and efficient water distribution.
• Rail and transportation: Rail and transport connections aid in building flanged joints in conveyance systems, such as the pipeline utilized in conveying oil under the land or sea.

How to choose flange forming machines

Before ordering flange forming machines in bulk for sale, it's a good idea to consider the following key buying tips:

• Industrial-grade build quality

  Always choose machines with strong, externally-built frames. A heavy cast iron or steel frame generally has suitable strength. Secondly, order machines with a durable coating. Corrosion, rust, and wear resistance will be improved with the right coating.

• Flange forming types

  Select machines that can form the flanges demanded by customers. The most popular types are riveted, flanged, cone-shaped, flat, bell or saucer-shaped, and the Flander type. Also, consider whether the die sets need to be customized for other flange types.

• Hydraulic vs. manual machines

  Decide whether to sell manual or hydraulic machines. Manual machines are less costly and ideal in low-tech workshops. However, they need more physical effort. Hydraulic machines are easier to use, but they cost more. Consider the typical workshop conditions and technicians' skill levels for this decision.

• Die Materials

  The machine comes with die sets made from different materials. Steel die sets are strong and long-lasting, but they may need extra lubrication. Aluminum die sets need less lubrication but wear out faster. Acetal and nylon are suitable for non-stick materials requiring minimal lubrication or cooling. Decide on the proper die material based on the flange types and materials.

• Operator safety

  Ensure the machine has safety features such as guards, emergency stop buttons, and overload protection. Check for proper safety instructions in the operator manual. Customer safety is vital, so choose machines with operator safety in mind.
