Forged flanges are used as fittings to form a piping network for cylinders, valves, pumps and other equipment. Forged flanges combine two separate machinery parts together. They can be an extension to a structure in order to make the object stronger.
Forged flanges offer high strength, excellent pressure resistance, precise dimensions, superior sealing performance, corrosion resistance, and long service life, ensuring safe and reliable connections in demanding industrial applications.
Depending on the material chosen, forged flanges exhibit excellent corrosion resistance, making them suitable for applications where exposure to corrosive elements is a concern.
Forging allows for precise shaping and dimensional accuracy, ensuring tight tolerances and proper alignment of bolt holes.
Forged flanges come in various types, such as weld neck, slip-on, socket weld, and blind flanges, providing versatility to suit different piping configurations and requirements.
Forged flanges are available in different pressure classes, allowing users to select the appropriate flange based on the specific pressure requirements of their system.
The forged construction enhances the ability of flanges to withstand extreme temperatures, making them suitable for applications in both high and low-temperature environments.
Due to their robust manufacturing process, forged flanges are known for their reliability in critical applications, reducing the risk of leaks or failures.
Forged flanges provide a smooth sealing surface, promoting effective sealing with gaskets and preventing leakage.
With standardized dimensions and bolt hole patterns, forged flanges are relatively easy to install, facilitating quick and efficient assembly of piping systems.
Types of Forged Flange include a wide range of designs developed to meet different piping and pressure requirements. Common types are weld neck, slip-on, blind, socket weld, threaded, and lap joint flanges. Weld neck flanges are ideal for high-pressure and high-temperature applications because their tapered hub provides excellent stress distribution.
Welding neck flanges are popular for their long tapered neck, with the accompanying connection, and their end is welded to the bottom. The internal diameter of the pipe is the same as the flange. It is useful in extreme jobs where there is a requirement of high stress.
The tube penetrates the cube of the same as in the form of carbon steel flanges. You do not need to touch the plane to the face to which it is connected with the use of external and internal welding seams. Due to the lower accuracy of the tube life and better positioning flexibility, we can consider it simpler than the neck flange. The mechanical condition of the sliding flange is usually good for exhaustion and strength, but much weaker than the neck-straps.
The design is such that it covers the ends of the tube openings, valves, or tubing due to various operating pressures. It is a form of ASME fitting that from a technological point of view is capable to withstand the most extreme working conditions.
Although they do not possess any welding characteristics, they make assembly easy and quick. It is useful for specific applications (e.g., in pipes with high atmospheric temperatures and pressures) where male NPT threaded pipes are utilized.
Because the unique impact strength function is significantly improved compared with other solid wall tubes, the ring stiffness is 1.3 times that of the solid wall.
The pipe under the rated use temperature and pressure, has a service life of more than 50 years, with anti-UV, anti-radiation, so that the product will never fade.
In addition to a few hydrogenating agents, can withstand a variety of chemical media corrosion, the flange has excellent acid, alkali, corrosion resistance, will not rust, will not erode, will not breed bacteria, no electrochemical erosion.
Because the material thermal conductivity is low, the thermal conductivity of 20 degrees Celsius is 0.21-0.24W / mk, much smaller than steel pipe (43-52W / mk), purple steel pipe (333W / mk), so PP-R Good tube insulation
When the working water temperature is 70 degrees, the softening temperature is 140 degrees.
Petrochemical Industry
Forged flanges play an important role in the petrochemical industry, as this is where a multitude of oil and gas pipelines made up of pipes and other components are found:
Pipelines are systems that are responsible for transporting oil and derivatives such as biobutanol by means of a system of pumping stations that drive the fluid at an average speed of between 1 and 6 meters per second. Given the complexity and dimensions of their structure, studies on the environmental impact must be carried out before construction. They are centered on steel pipes whose diameter varies from ½ inch (12.7 mm) to 144 inches (approximately 360 cm).
Gas pipelines have the same function, transporting materials, but in this case the materials are combustible gases, mainly natural gas. They do this at high pressures. The lines are mostly built underground at a depth of one or two meters depending on the terrain; rarely above ground. It is standard practice that shutoff valves be placed at various points in the pipeline to cut off the flow of gas if necessary.
In both cases, pipelines are used to transport materials that require specific treatment both in their extraction and in their transportation or processing. Oil and its derivatives are very corrosive and contaminating, and natural gas can flow at low temperatures (-161º). The materials that both types of conduits are made from need to be just right for their planned application to avoid negatively affecting the surrounding flora and fauna. This is also why sections of pipe are joined with forged flanges, whose corrosion resistance can be increased thanks to techniques such as cladding / weld overlay.
Choose the type of forged flange that best suits your application. Common types include weld neck, slip-on, socket weld, and blind flanges.
Consider the material of the forged flange based on the requirements of your specific application. Materials like carbon steel, stainless steel, and alloy steel offer different levels of strength and corrosion resistance.
Ensure that the dimensions, pressure ratings, and specifications of the selected forged flanges match the requirements of your piping system.
Clean and prepare the ends of the pipes that will be joined using the flanges. Ensure that the pipe ends are straight, smooth, and free from any debris or contaminants.
Place the appropriate gasket between the facing surfaces of the flanges. Gaskets help create a seal, preventing leaks in the joint.
Align the bolt holes of the flanges with those of the connected pipes. Proper alignment is crucial for a secure and leak-free connection.
Insert bolts through the aligned bolt holes and tighten them evenly and progressively. Follow the recommended torque values for the specific size and type of bolts used.
Verify that the flanges are properly aligned and that there are no gaps or misalignments. This ensures a secure and leak-resistant connection.
After installation, inspect the connection for any signs of leaks. Perform a pressure test if necessary to ensure the integrity of the joint.
If required, apply paint or coating to the flanges for additional corrosion protection, especially in corrosive environments.
Adhere to industry standards and guidelines for the specific type of flange and application to ensure compliance and safety.
Periodically inspect the forged flange connections for signs of wear, corrosion, or damage. Perform maintenance as needed to ensure long-term reliability.
Visual Inspection – Make sure you visually inspect your flanges for damage or cracks. If you see any signs of wear, you will need to replace the flange. You can use a mirror to inspect the flange from a different angle.
Pressure Test – You should pressure test your flanges every year to ensure that they are in good condition and can be used without issues.
Corrosion Protection – Some flanges are more susceptible to corrosion than others. You can prevent corrosion by cleaning flanges regularly and using special paint or protective coatings to prevent corrosion.
The method of forging typically consists of the following procedures, which are blanking, heating, shaping, and cooling. The method of forging can be classified as free forging or a die forging operation.
Free forging has low productivity and high machining allowance, but the tool is simple and versatile, so it is widely used for forging one-piece and small series forgings with a simple geometry. On the other hand, die forging has the advantages of simple operation, high productivity, mechanization, and automation. Die forgings have high dimensional accuracy, a small machining allowance, and a more reasonable grain structure distribution, which can further improve the service life of flange parts.
Die forging is also known as model forging. Follows the basic steps: blanking, heating, pre forging, final forging, punching and connecting skin, trimming, tempering and shot peening. Common processes include upsetting, drawing, bending, punching and forming.
The widely used die-forging machineries are forging hammer , hot die forging press, flat forging system, and friction press. The forging flange is normally of higher quality, typically by die forging, the crystal structure is good, the strength is high and the price is of course costlier.
Free forging refers to a method of forging where the heated iron/steel is anchored and then formed by hammering, pressing, or other methods. Free forging can flexibly form the shape of each product and is suited for making large components or for diversified small-quantity production. As mentioned before, free forgings productivity is low and the machining allowance is large, but the tool is simple and the versatility is large, so it is widely used for forging a single piece and a small batch of forgings with a simple shape.
