Pipeline collars (flanges) are fitting elements used to connect pipes, valves and other components such as pumps or drain devices to form a piping system.
Flange connection is the most popular, cheap and easy-to-install method of joining and expanding the system, including connection with flexi hoses. There are different types of nickel collars and nickel flanges, such as welding neck flanges, blind and threaded collars and for large-diameter pipes loose flanges are used.
Most common usage of nickel collars
Nickel joining collars are usually welded while nickel flange joints are made by bolting two flages together to make a simple, cheap and tight seal. They are used to create extensive and developed pipeline systems, used in waterworks, gas and sewerage or other parts of the industrial equipment.
We supply nickel collars and nickel flanges, seamless and welded, short or long, in any desired dimension or size. All our nickel collars are made in accordance with ASTM standards and conform to Pressure Equipment Directive – ASME and MSS SP-43.
