Key Features & Benefits of Dipti Metal Industries' Socket Weld Flanges Class 150
Dipti Metal Industries' Socket Weld Flanges Class 150 are expertly designed and manufactured to provide essential functions that enhance the reliability and longevity of general service piping systems. Here are the key features and the significant benefits they deliver:
- Reliable Moderate Pressure Resistance: Engineered for Class 150 pressure ratings, these flanges are well-suited for a broad range of general industrial applications including domestic water, utility lines, and lower pressure process systems.
- Superior Leak Integrity: The socket weld design, where the pipe is inserted into the flange and then fillet welded, provides a very strong, permanent, and inherently leak-proof connection, reducing the risk of minor leaks.
- Good Structural Strength: The combination of forged material and the fillet weld creates a robust joint capable of handling standard mechanical stress and vibration without compromising integrity for its pressure class.
- Ideal for Small-Bore Piping: Particularly well-suited for smaller nominal pipe sizes (NPS 1/2" to 2" typically) where the strength and leak resistance of a socket weld connection are highly advantageous compared to threaded or slip-on alternatives.
- No Beveling Required for Pipe End: Simplifies pipe preparation, as the pipe end does not need to be beveled, reducing fabrication time and cost compared to butt-weld flanges.
- Cost-Effective & Versatile: Class 150 flanges are often a more economical choice for applications that do not require extremely high-pressure capabilities, offering versatile use across many industries.
- Reduced Weld Distortion: The fillet weld allows for less distortion than a full butt weld, which can be beneficial in certain applications and simplifies alignment.
Our Comprehensive Product Range: Socket Weld Flanges Class 150
Dipti Metal Industries manufactures and supplies an extensive and high-quality range of Socket Weld Flanges Class 150 from Mumbai, India. We offer diverse types, international material grades, face types, and dimensions, custom-engineered to meet the precise moderate-pressure connection requirements of your industrial applications globally.
1. Flange Type & Pressure Class
- Socket Weld (SW) Flanges: Designed with a recessed shoulder that allows the pipe to be inserted and then fillet welded around the outside. This provides a strong, leak-proof connection, particularly suited for moderate-pressure, small-bore piping.
- Pressure Class 150: Specifically manufactured to withstand moderate pressures, making them ideal for common industrial, commercial, and utility applications.
2. Face Types Available
- Raised Face (RF): The most common type for Class 150, featuring a raised gasket surface above the bolting circle. This concentrates the compressive load on a smaller gasket area, increasing the joint's ability to contain pressure.
- Flat Face (FF): Often used when connecting to cast iron flanges, pumps, or valves that are sensitive to the concentrated loading of a raised face, to prevent breakage.
- Ring Type Joint (RTJ): Less common for Class 150 but available for specific applications requiring a metal-to-metal seal or where pressure/temperature spikes may occur.
3. International Material Grades
We manufacture Socket Weld Flanges Class 150 from various materials chosen for their strength, durability, and corrosion resistance under moderate-pressure conditions, conforming to major international standards:

Socket Weld Flanges Class 150 — Frequently Asked Questions
Socket Weld (SW) Flanges Class 150 are forged pipe flanges designed for general industrial and moderate-pressure applications. The pipe is inserted into a recessed area (the 'socket') of the flange and then secured with a single fillet weld on the outside of the flange hub. This design creates a robust, leak-proof connection that is particularly suitable for small-bore piping systems (typically NPS 1/2" to 2") handling common pressures and temperatures found in water lines, HVAC, and auxiliary systems. The Class 150 designation refers to its pressure rating as per ASME B16.5, making it a versatile choice for many commercial and industrial uses. Dipti Metal Industries manufactures and supplies these flanges globally, ensuring they meet stringent international standards for reliable industrial use.
The key benefits of using Socket Weld Flanges Class 150 from Dipti Metal Industries include:
- Moderate Pressure Rating: Ideal for common industrial pressures, offering reliability without over-engineering for less demanding applications.
- Good Leak Integrity: The socket design with a fillet weld provides a strong, permanent, and inherently leak-resistant joint, crucial for reliable fluid containment.
- Solid Mechanical Strength: Offers good strength and fatigue resistance for general service piping, suitable for typical operational stresses.
- Cost-Effective: Often a more economical choice compared to higher-pressure rated flanges, providing excellent value for moderate pressure applications.
- Suitable for Small Diameters: A preferred choice for smaller pipe sizes (typically 1/2" to 2") where a strong, permanent connection is required.
- No Pipe Beveling Required: Simplifies pipe preparation, reducing fabrication time and costs.
Dipti Metal Industries offers Class 150 Socket Weld Flanges in a wide array of materials to suit diverse industrial conditions:
- Carbon Steel: ASTM A105 (for general service) and ASTM A350 LF2 (for low-temperature applications). We also supply to EN standards like P250GH.
- Stainless Steel: ASTM A182 F304/304L and F316/316L for excellent corrosion resistance, especially in water, chemical (diluted), and marine environments where Class 150 pressure rating is adequate. European equivalents include 1.4301 and 1.4401.
- Alloy Steel: ASTM A182 F11 and F22 are available for Class 150 applications requiring moderate elevated temperature performance with some creep resistance.
- Raised Face (RF): The most common choice, concentrating gasket pressure for an effective seal.
- Flat Face (FF): Often specified for connections to equipment or valves that have flat face flanges (e.g., cast iron) to prevent damage.
- Ring Type Joint (RTJ): Less frequent for Class 150 but can be provided for specific applications requiring a metal-to-metal seal or extra resilience.
Socket Weld Flanges Class 150 are fundamental fasteners used across numerous industries for piping systems requiring moderate pressure capabilities:
- General Utilities: Widely employed in water lines (domestic and industrial), compressed air, and low-pressure steam lines.
- HVAC Systems: Essential for chilled water, hot water, and low-pressure heating circuits in commercial and large residential buildings.
- Building Services: Used in plumbing, drainage, and other non-critical building infrastructure.
- Fire Protection: Key components in fire sprinkler systems and standpipes.
- Food & Beverage: For various utility lines and non-sensitive process piping.
- Auxiliary Systems: In many industrial settings for cooling loops, wash-down stations, and other support systems that do not experience high pressures.
Our Socket Weld Flanges Class 150 are manufactured in strict accordance with major international standards to ensure quality, safety, and interchangeability:
- ASME B16.5: The primary standard for pipe flanges and flanged fittings up to NPS 24, which governs the dimensions, materials, pressure-temperature ratings, and testing of Class 150 SW flanges.
- ASTM Standards: Specific material standards such as ASTM A105 (carbon steel), ASTM A350 LF2 (low-temperature carbon steel), and ASTM A182 (alloy and stainless steels) ensure the mechanical and chemical properties of the forged materials.
- DIN / EN Standards: For projects requiring European specifications, we adhere to standards like EN 1092-1, which provides dimensions and pressure ratings (PN) such as PN10 or PN16 that correlate to Class 150 depending on service temperature.
- BS 1560: British Standard for circular flanges, often used for applications equivalent to ASME Class 150.
- JIS B2220: Japanese Industrial Standard for steel pipe flanges, where 10K flanges are frequently comparable to Class 150.
