FLANGE
Application:For seal or connect of pipe/tub-e lines
Material:304,304L,316,316L,nickel alloyother material on request
Standard:ANSI,DIN,JIS,BS,EN1092-1
Size:DN15 (1/2") to DN5000 (200")
Type:Threaded Flanges, Socket Welding Flanges, Blind Flanges, Other Flanges
Welding neck
| Preferred for high-pressure, subzero or elevated temperature |
| Hub is tapered and bored to match pipe's inside diameter so flow is not restricted, preventing turbulence and reducing erosion |
| Easily radiographed and provides excellent stress distribution |
Slip-on
| Not normally used in high-stress applications due to low hub and weld attachment |
| Silps over outside of pipe |
| Inside of flange welded at hub and end of pipe |
Lap joint
| Used where bolt alignment or access for cleaning is required |
| Similar to slip-on flange when used with lap joint stub end |
| Radius at intersection of flange face and bore to match lap joint stub end |
Threaded
| Used where welding would would be hazardous |
| Designed for low-pressure and non-cyclic applications |
| Bore is threaded to match pipe thread |
| Tapered to seal pipe and flanges |
Socket welding
| For small-diameter chemical processes, hydraulic and stream distribution lines |
| Similar to slip-on flange |
| Counter bore matches pipe bore, allowing unrestricted flow |
| Counter bore from hub side fits pipe's outer diameter - can insert pipe in socket with fillet weld at hub |
Blind
| Used to close ends of piping |
| Has no bore |
| Permits access to sealed lines |
