Socket Weld flange for bolted pipe connections. Socket weld flanges for small-bore high-pressure piping. Carbon Steel construction. Socket Weld flange — 300# rated Carbon Steel body for durability and long service life Raised face per ASME B16.5 / B16.1 standard Mates with standard 300# flanges and flange fittings ✔ In Stock — Ships Same Day or Next Business Day✔ Used by contractors and professionals✔ Designed for reliable jobsite performanceOverviewWeldbend Carbon Steel 300# Socket Weld Flange is a socket weld flange for bolted piping connections on water, steam, and industrial fluid systems. Socket weld flanges accept small-bore pipe into a recessed socket and are fillet-welded — preferred for high-pressure small diameter piping. Flanges are fabricated to ASME B16.5 (300#) dimensional standards.Common Uses Connecting pumps, valves, and equipment to flanged piping systems Water, steam, and industrial process fluid piping General commercial and industrial piping construction HVAC mechanical piping systems Municipal water and wastewater systems Key Features Socket Weld design — high-pressure small-bore piping Carbon Steel construction 300# pressure class rating Raised face per ASME B16.5 / B16.1 Specifications Material Carbon Steel Type Socket Weld Flange Pressure Class 300# Face Raised Face Standard ASME B16.5 Frequently Asked QuestionsWhat is the difference between a 150# and 300# flange?150# flanges are rated for lower pressures and are the standard for most commercial water and HVAC applications. 300# flanges have thicker walls and are rated for higher pressures and temperatures.What is the difference between weld neck and slip-on flanges?Weld neck flanges are welded at the neck and provide superior strength for high-pressure and cyclic service. Slip-on flanges slide over the pipe and are fillet-welded — faster to fit but not as strong as weld neck.What gasket do I need with a raised face flange?Raised face flanges typically use a full-face or ring gasket. Spiral wound or ring-type joint gaskets are used on higher-pressure applications.Are flanges supplied with bolts and gaskets?Flanges are typically supplied individually — bolts, nuts, and gaskets are ordered separately based on service requirements.Why Contractors Choose This Product Blind flanges let you pressure-test a system before all connections are made — standard practice in commercial construction 300# rating covers the pressure range for most commercial and industrial water and steam applications Carbon Steel construction for reliable long-term service PVFPro stocks the full range of flange types, sizes, and pressure classes Buying in volume?
