Plate flanges have a gasket surface that’s in the same area as the bolting circle face. They are commonly used in applications where the mating flange or flanged fitting is made from a casting. At Rayoung, we offer carbon steel and stainless steel plate flanges in a variety of sizes, thicknesses, and standards, ensuring that we meet your project needs. What Are Plate Flanges? Plate flanges start as flat sheets of steel. They are usually cut from carbon steel or stainless steel plates. After cutting, workers machine them to exact sizes. This includes drilling the bolt holes and the center opening. Unlike forged flanges, these do not undergo high-pressure shaping. They simply begin as a flat piece of metal. Since they aren’t forged, these flanges are cheaper to make. The production process is much simpler. Most people weld them directly onto the pipe. This is why they are often called “welded plate flanges.” These flanges are perfect for low-pressure jobs. You don’t need heavy-duty strength for these systems. They typically handle pressures up to 300 psi. You will commonly see them in water lines, gas pipelines, and general factory setups.

Quality Guarantee for Large Projects: We understand the requirements of terminal users in the Oil, Gas, and Power industries. Every Slip-On flange undergoes 100% visual and dimensional inspection. Types of Slip-On Flanges and Their Applications SO flanges are available in two main types, each designed to cater to specific requirements and applications within piping systems: Standard Slip-On Flanges: Standard or raised-face SO flanges have a raised face on the sealing surface. They are highly suitable for low-pressure applications where the bolt- tightening force can compress the gasket adequately to prevent leakage. Lap Joint Slip-On Flanges Lap joint SO flanges have a flat face with a separate backing flange. They are commonly used in systems requiring frequent dismantling, thermal expansion, or contraction applications. Cost-Effectiveness: Genera , lly, slip-on flanges are more cost-effective than other types of flanges, such as weld neck flanges, due to their simpler design and installation process. Material: They can be made from various materials, including carbon steel, stainless steel, and other alloys, depending on the application requirements. Limitations: While slip-on flanges are versatile, they may not be suitable for high-pressure applications due to the potential for leakage at the weld joint. Slip On Flange vs Weld Neck Flange The strength for internal pressure of the Slip-On Flange is two-thirds of Weld Neck Flange. Durability life is 1/3 of the WN flange. 2 fillet welds are required for the SO flange, one inside and one outside of the flange. A space shall be reserved between the end of the pipe and the end of the flange during welding work, to avoid damage to the flange face. The slip-on flange has to connect with a pipe first, then connect to a fitting. (Combination of flange+elbow, or flange+tee not available, since the fittings are not in a straight end, it can not slide completely into the flange bore. ) Slip-on flanges are usually cheaper than Weld-Neck flanges (welding neck flange), which is why many customers prefer to choose them. It is one of the commonly used flanges for low-pressure, medium-temperature piping systems. On the other hand, since the flange bore is larger than the pipe diameter, it usually requires more welding work than the other flanges. So the durability is not as long as the welding neck flange; all of these factors should be considered before choosing the right flange.

What is a Cast Iron/Steel Flange? Casting is one of the oldest metalworking methods. It involves heating the metal until it is molten and then pouring it into a pre-shaped mold. Once cooled, the metal solidifies into the shape of the flange. Key Characteristics of Casting: High Production Efficiency: Casting allows for high-volume production of complex shapes that would be difficult or impossible to forge. Low production cost: Due to lower energy requirements and less labor-intensive processing, cast flanges generally come at a lower price point. Precision and Complexity: Modern casting (such as investment casting) can achieve very accurate dimensions, reducing the need for extensive CNC machining. Inherent Risks: The cooling process in casting can lead to “casting defects” such as porosity (air bubbles), shrinkage cracks, and non-metallic inclusions. These internal flaws are often invisible to the naked eye but can fail under high pressure. What is a Forged Steel Flange? Forging is a mechanical process where the steel is heated to a plastic state and then hammered or pressed into shape using localized compressive forces. This “working” of the metal physically changes its internal structure. industrial forged steel flanges Key Characteristics of Forging: Structural Integrity: Forging refines the grain flow of the steel, aligning it with the shape of the flange. This results in superior mechanical properties, including higher tensile and shear strength. Density: The high pressure of the forging process eliminates internal voids and gas pockets, creating a dense, compact molecular structure. Durability: Forged flanges exhibit better resistance to fatigue and impact, making them the standard for critical infrastructure. Costs are higher than those of cast flanges: The forging process requires massive machinery and multiple heating cycles, which reflects in a higher unit cost compared to casting.

ASME B16.9 Butt Weld Eccentric Reducer Seamless eccentric reducer for butt welding Sch40 (Std) weight wall thickness Made of black ASTM A234 WPB carbon steel Material Conforms to the ASME B16.9 standard for butt weld fittings. Buttweld Reducers are one of the many types of fittings that can be used to control the flow within a piping system. In a piping system, there are two major types of reducers: concentric reducers and eccentric reducers. What is an Eccentric Reducer? The eccentric reducer is a butt weld pipe fitting used to connect two pipes of different diameters whose centers are not on the same straight line. Since the centers are not coincident, the eccentric reducer has the function of changing the direction of the pipe, balancing the pipe deviation, and reducing stress concentration. Unlike a concentric reducer, this offset design helps to maintain smooth fluid flow while reducing the risk of turbulence, particularly in systems that carry thick or viscous fluids. Eccentric reducers are highly effective in oil refineries, chemical processing plants, and systems transporting sludge, where maintaining consistent flow without pressure drop is crucial.

ASME B16.9 Butt Weld Concentric Reducer Seamless concentric reducer for butt welding Sch40 (Std) weight wall thickness Made of black ASTM A234 WPB carbon steel material Conforms to the ASME B16.9 standard for butt weld fittings. Concentric Reducer Design and Construction Concentric reducers typically have a conical shape, with one end having a larger diameter than the other. The tapering transition allows for a gradual reduction in pipe diameter, minimizing turbulence and pressure losses within the piping system. These reducers are commonly manufactured using materials such as carbon steel, stainless steel, and various alloys, ensuring durability and corrosion resistance. Concentric Reducer Applications: Concentric reducers find widespread applications across various industries, including: 1. Chemical Processing: Used in chemical plants to connect pipelines carrying different chemicals or fluids. 2. Oil and Gas: Employed in pipelines for crude oil, natural gas, and refined petroleum products. 3. Water Treatment: Utilized in water distribution systems to transition between pipes of different sizes. 4. HVAC Systems: Integrated into heating, ventilation, and air conditioning systems for ductwork modifications.
