Contact SupplierFlanges are relatively simple mechanical connectors that have been used successfully for high-pressure piping applications. Pipe flanges have flush or flat surfaces that are perpendicular to the pipe to which they attach. Two of these surfaces are mechanically joined via bolts, collars, adhesives or welds. In addition, the moment-carrying capacity of flanges is significant compared to other mechanical connectors. This is an important feature for systems that experience pipe-walking or lateral buckling from temperature and pressure variations (e.g. deep water lines). Flanges can be designed to meet a wide range of application requirements such as high-temperature and corrosion resistance.
Type | Pressure Capacity | Pipe Sizes | Applications / Advantages |
---|---|---|---|
Lap joint | Low | All | Systems requiring frequent disassembly |
Slip-on | Low | All | Low installation cost, simple assembly |
Socket weld | High | Small | Smooth bore for better fluid flow |
Threaded | Low | Small | Attachment without welding |
Welding neck | High | All | High pressures and extreme temperatures |
Blind | Very high | All | Closing pipes, flow pressure testing |
