Socket weld flanges, also known as SW flanges, have a recessed area (like a shoulder) in the flange bore. This shoulder serves as a guide to set the depth of the pipe that is inserted into the flange. Socket weld flanges are a less common but equally effective connection for flanges that require less overall available space than a traditional weld neck flange, with a counterbore in the center to allow for a clean weld of pipe into the socket. The advantage of socket weld flanges is their simple design; they are well- suited for small pipe size applications, and for non-critical applications, e.g., non-hazardous systems; they are not suitable for highly erosive or corrosive systems. Socket welded flange including RF type and RTJ type, which like other types of welding flanges (slip-on, weld neck, or blind flange). Socket Weld Flanges Application: Socket weld flanges are commonly used in high-pressure piping systems such as chemical processing, petrochemical refining, oil and gas, and power generation systems. These flanges efficiently connect pipes to valves, fittings, and equipment while offering high reliability and safety. In some instances, socket weld flanges are used in small-bore piping systems such as steam, air, water, and gas pipelines where high pressure and temperatures exist. Key Features: Material: Manufactured using superior quality steel, offering high strength, durability, and corrosion resistance. Sizes: Available in diverse sizes to accommodate various pipe diameters. Custom sizes also available on request. Standards: Complies with ASME B16.5 and B16.47 standards, ensuring high-quality and compatibility with a wide range of pipe fittings. Design: The recessed design of the socket weld flange allows for precise alignment of the pipe and flange, reducing the risk of leakage. Applications: Perfect for high-pressure applications and smaller pipe sizes. Widely used in industries such as oil & gas, chemical processing, power generation, and more. Socket welded flange including RF type and RTJ type, which like other types of welding flanges (slip-on, weld neck, or blind flange). Socket Weld Flange vs Slip On Flange Socket welded flange shape is similar to slip on flange, differently it has a shoulder at the inner bore. Slip On Flange – No shoulder at inner bore. Socket weld flange static strength is equal to slip on flange, but it’s fatigue strength is 50% higher than the double welded slip on flange. With our Steel Socket Weld Flanges, you can expect a high-quality, reliable solution for your piping system needs. We are dedicated to delivering products that not only meet but exceed industry standards.

Plate flanges are commonly used in applications where the mating flange or flanged fitting is made from a casting. JSFITTINGS offers plate flanges according to ASME/ANSI B16.5 and GOST,EN1092 standards, in both carbon steel and stainless steel. What are Plate flanges? A Plate Flange is a type of flange that is made from a flat piece of metal, typically steel or stainless steel. The flange is cut and formed to shape, with a raised face on one side and a recessed area on the other side. It is often referred to as a flat flange, a plain flange, and flange slip, etc. Two plate flanges can be bolted together with a gasket in between them, usually used in fuel and water pipelines. Plate flanges have a serrated finish on the inner mating surface, allowing the plate to fit within the material of the gasket. In any given dimension, plate flange designs are standardized regardless of the materials used to manufacture them. What are the plate flange Advantages? Plate flanges have several advantages, such as: Easy to Manufacture: Plate flanges can be easily manufactured by cutting and shaping a flat plate. Cost-Effective: Plate flanges are relatively inexpensive compared to other types of flanges, making them a cost-effective option. Customizable: Plate flanges can be customized to suit specific application needs, such as different pressure ratings and sizes. ASME ANSI B16.5 Plate Flange Plate flanges Application: Plate flanges have several uses, such as: Piping Systems: Plate flanges are commonly used in piping systems to connect pipes and other fittings. Industrial Applications: Plate flanges are used in various industrial applications, such as oil and gas, chemical, and power plants.

Blind flanges are used to close off the ends of pipes, valves, or other equipment, providing a secure seal. Blind Flanges – The Essential Pipeline Closure Solution What Are Blind Flanges? Blind flanges (also termed “closure plate flanges”) serve as permanent or temporary termination points in piping systems. Unlike standard flanges, they feature a solid center without a borehole, creating an impenetrable seal when bolted to pipe ends, valves, or pressure vessels. At JSFITTING, we manufacture industry-compliant blind flanges in all sizes and pressure classes, offering three sealing face variants: Flat Face (FF) Raised Face (RF) Ring-Type Joint (RTJ) Our Blind Flanges Core Features & Benefits 1. Flow Isolation No central opening ensures zero media leakage—critical for system maintenance or pressurization testing. 2. Multi-Functional Adaptability Convertible to slip-on flanges via drilling Threadable for threaded flange applications 3. Material Versatility Available in: Carbon Steel (ASTM A105) Stainless Steel (A182 F304/316) Alloy Steel (F11/F22/F91) 4. Pressure-Containment Ready Designs comply with ASME B16.5/B16.47 pressure ratings from Class 150 to 2500. Key Applications Oil & Gas Platforms Pipeline pigging isolation Wellhead termination Chemical Plants Reactor vessel sealing Water Treatment Pump discharge termination System expansion cap points Installation Best Practices 1. Gasket Selection Guide: RF Flanges: Use ring gaskets (RTJ for high-pressure) FF Flanges: Require full-face gaskets to distribute bolt loads 2.

Dimensions: ASME/ANSI B16.5, ASME B16.47, GOST 12820, EN1092, GOST 12821, GOST 33259 What is a threaded flange? A forged threaded flange（also called companion flanges/screw flanges / NPT flanges/TH flanges） is a type of pipe flange that features internal threads on its bore, allowing it to be directly screwed onto the external threads of a pipe. This design eliminates the need for welding, making it a convenient choice for pipes that cannot be welded or in situations where welding is not desirable. Key Features & Applications 1. Welding-Free Connection – Perfect for explosive or flammable environments (e.g., petrol stations, chemical plants) where welding sparks pose a risk. 2. Easy Installation & Maintenance – Can be quickly assembled or disassembled compared to welded flanges. 3. Cost-Effective for Small Pipes – Typically used for ½” to 6” pipes, though larger sizes (up to 24”) are available upon request. The amount of additional machining and labor hours that go into producing a larger diameter threaded connection makes them less popular than slip-on flanges or weld neck flanges. 4. Limited to Low-Pressure/Low-Temperature Use – Best suited for non-toxic fluids and moderate conditions, as threads may weaken under high heat or pressure. 5. Face Types – Only available with flat face (FF) or raised face (RF) finishes, not suitable for high-pressure ring-type joints.

Clean the pipe threads and the inside of the flange to ensure a secure and leak-free connection. Align the threaded flange with the pipe and screw it onto the pipe’s threaded end by hand until it is snug. Use a wrench to further tighten the flange onto the pipe. Be careful not to over-tighten, as this can damage the threads or pipe. Optionally, use thread sealant or Teflon tape to prevent leaks in lower-pressure systems, ensuring a tight seal.
