Weld neck carbon steel flanges feature a tapered hub and long neck welded directly to pipes for superior strength and reduced stress concentration in high-pressure systems. Common grades like ASTM A105 provide excellent weldability and toughness for temperatures up to 425°C.​

Dimensions

Per ASME B16.5 standards, sizes range from 1/2" to 24" NPS across classes 150-2500. For Class 300 1/2" size: OD 95 mm, thickness 12.7 mm, hub OD 38 mm, bore matches pipe schedule, bolt circle 66.7 mm with 4 x 1/2" bolts.​

ASTM A182 flanges are forged or rolled alloy and stainless steel components (flanges, fittings, valves) for high-temperature pressure systems, designed to connect pipes and equipment, offering strength and corrosion resistance with specific grades like F11 (chrome-moly) or F316 (stainless) for various demanding industries like oil, gas, and power. 

A Mild Steel (MS) Weld Neck Flange is a strong, butt-welded pipe fitting with a long, tapered hub that seamlessly connects to pipe, ideal for high-pressure/temperature systems like oil, gas, and water, offering excellent stress distribution, leak-proof performance, and enhanced system integrity. It's preferred for critical applications due to its robust construction, smooth bore reducing turbulence, and durable, often galvanized, finish that resists corrosion. 

A Mild Steel (MS) Socket Weld Flange is a strong pipe connector for smaller, high-pressure systems, featuring a recessed "socket" where the pipe inserts, creating a strong, leak-proof joint via a fillet weld around the hub, offering smooth bore and excellent flow for demanding industries like oil & gas, chemical, and power.
