Compact & Leak-Tight Alloy Socket Weld Flanges ASME B16.5 CLASS300

erosion turbulence. Fillet welding is simpler to perform than butt welding in tight spaces.Alloy Steel Socket Weld Flanges are designed for small-diameter piping systems (typically 2" and below) where high leak integrity is paramount. The pipe is inserted into the socket of the flange and then fillet-welded around the outside, creating a smooth bore and a strong, reliable joint. They are a preferred choice for instrument lines, sample points, and high-pressure utility lines in chemical and power plants.

Product Description:
This flange has a counterbore (socket) that matches the pipe's outer diameter, allowing the pipe to be inserted until it bottoms out, leaving a small internal gap for thermal expansion before welding. Made from alloy steels like ASTM A182 F316 or F11, it ensures excellent flow characteristics and joint strength.

Key Parameters:
Commonly used in ASME B16.5 pressure classes from Class 150 to Class 3000 for small sizes (1/2" to 2" NB). The socket depth and machining are precise to ensure proper pipe seating. Standard face types are Raised Face (RF). Materials comply with ASTM A182 for corrosion and heat resistance.

Applications:
Predominantly used for small-bore, high-pressure lines in hydraulic systems, instrument tubing, chemical injection lines, steam tracing, and boiler feedwater systems. Ideal for services where turbulence and fluid restriction at the joint must be minimized.

Advantages:
Provides excellent leak resistance and high structural strength for small-diameter pipes. Easier to align than butt-weld fittings for small lines. The smooth bore reduces pressure drop and minimizes corrosion

Functionality:
Creates a permanent, robust, and leak-proof connection in small piping systems where space is limited and reliability is critical. The internal shoulder provides inherent support for the pipe, and the fillet weld ensures a durable seal against high internal pressures.
