Flanges are a method of connecting pipes, valves, pumps, and other equipment to form a piping system, usually by welding or threading. It is also easy to clean, inspect or modify. Flanges are usually welded or tightened. Flange joints are made by bolting two flanges together and using washers between them to provide a seal.
Pipe assemblies may be bolted together between flanges. Flanges are used to connect pipes to each other, to valves, to fittings, and to special items such as filters and pressure vessels. Cover plates can be connected to create "blind flanges". Flanges are bolted together, and sealing is usually done using washers or other methods. Industries dealing with flammable, volatile, toxic or corrosive substances require special protection at flange joints. Flange shields can provide an additional level of protection to ensure safety.
There are many different flange standards worldwide. For simple functionality and interchangeability, these designs have standardized dimensions. Common world standards include ASA/ASME (USA), PN/DIN (Europe), BS10 (UK/Australia) and JIS/KS (Japan/Korea).
In most cases, standards are interchangeable, as most local standards have been aligned with ISO standards.
Flanges are also made in standardized sizes, usually in "flat", "convex", "mortise" or "ring joint" styles, but other ambiguous styles may be available.
Flange designs include "weld neck", "socket", "lap", "socket weld", "thread" and "blind flange".

Super Cone Rubber Fender is the improved generation of cell fender, combining excellent energy capacity with low reaction force to give the most efficient performance of any fender type. The conical shape keeps the body stable under all combinations of axial, shear and angular loading, making it ideal for berths where large berthing angles and heavy impacts need to be accommodated. Generally, it is recommended for almost all types of applications such as cargo and container berths, high tidal sensitive structure and large sized docks.
