Used where welding would would be hazardous2. Designed for low-pressure and non-cyclic applications3. Bore is threaded to match pipe thread4. Tapered to seal pipe and flangesSlip-on1. Not normally used in high-stress applications due to low hub and weld attachment2. Silps over outside of pipe3. Inside of flange welded at hub and end of pipeSocket welding1. For small-diameter chemical processes, hydraulic and stream distribution lines2. Similar to slip-on flange3. Counter bore matches pipe bore, allowing unrestricted flow4. Counter bore from hub side fits pipe's outer diameter -  can insert pipe in socket with fillet weld at hubLap joint1. Used where bolt alignment or access for cleaning is required2. Similar to slip-on flange when used with lap joint stub end3. Radius at intersection of flange face and bore to match lap joint stub endBlind1. Used to close ends of piping2. Has no bore3.Permits access to sealed linesWelding neck1. Preferred for high-pressure, subzero or elevated temperature2. Hub is tapered and bored to match pipe's inside diameter so flow is not restricted, preventing turbulence and reducing erosion3.
