How ANSI B16.5 steel pipe flanges working?
ANSI B16.5 steel pipe flanges:
Pipe flanges also called flange plate. It is a very important accessary between pipes connection. ANSI B16.5 flanges are also used for the connecting between two equipments such as pipelines with valves or equipment.
Why choose pipe flanges connecting in the pipeline system?
In the pipelines two pipes can be welded together directly. But when there is a problem happened in the connection area, it will be difficult to be repaired. The same problem also occurs the connection between the pipe and valve. The above problem can be easily solved if flanged connection used in pipes or valves.
What components should be included in steel pipe flanged connecting?
The type of flange connection usually has two parts, gasket and bolt nuts (the pipe is welded to the flange first, then the valve and other equipment are mounted on the flange by bolts.) When connecting these parts, putting the gasket between the two flanges and tighten the bolts to make the two steel pipe flanges connected tightly together. In the case of piping maintenance, we can remove bolts from the flanges, take away the pipes or valves need to be repaired, and replace the new pipes and valves. In short, flanged connection makes the pipeline maintenance very convenient, flexible, and less effort.
Above mentioned information is just about the working process of ANSI B16.5 steel pipe flanges. ANSI B16.5 steel pipe flanges including many types, welding neck, slip on, blind, threaded, socket, lap joint and so on. Welding neck, slip on, and blind are the most usually used three types. Following let us share some features about them.
Welding neck flanges:
The neck of the welding neck flange can be welded directly to the pipe end. The welding neck flange has the specialities of convenient structure, high strength and good sealing performance. It is widely applied in different pressure piping specially high pressure.
Slip on flanges:
Slip on flange is short of SO flange. By inserting the pipe into the inner bore of the flange, the flange bore is slightly larger than the outer diameter of the pipe, and can be connected by a lap weld connection part at the top and bottom of the flange. The common sealing face type of slip on flange refers to RF, and FF. The feature of slip on flange is that the low cost, but the welding process is more complex than welding neck flange. It is usually used for middle and low pressure pipeline.
Blind flange:
Blind flange is a round disc only have bolt holes. It is generally used at the end of pipes to stop the flows just like the pipe cap.
