ANSI DIN Stainless Steel Pipe Flange With Raised Face RF
ANSI /DIN flanges are an essential component in the oil and gas industry, as they provide a reliable and secure connection between pipes.
They are used to connect pipes of different sizes and materials, allowing for flexibility in pipe design. ANSI /DIN flanges are also used to
prevent leaks from occurring, as well as providing a means of pressure release when needed.It is critical to choose the right size of ANSI /DIN flanges to ensure proper installation and performance in your piping projects. Here are also some steps to find the right size
Determine the pipe size/ Identify the pressure rating/ Select the material/Choose the facing type/Consider the flange type/Check the dimensions

Technology/ How to use and install the different flange types
WELDING NECK FLANGES
They are connected to the pipe by means of a Butt weld connection. They are
used when X-ray testing is required or if the torque over unions are maximum.
Its long tapered neck optimizes the stress distribution
SLIP-ON FLANGES
This kind of flanges are installed with two weld bead, sliding the pipe inside.
Thus installation costs are lower, so less accuracy is required for pipe cutting.
THREADED FLANGES
They are usually installed with the pipe previously threaded, in places where
welding cannot be done. We do not recommend to install if there are high
pressure variations in the system
LAP JOINT FLANGES
They slide on an overlapped gasket. They are commonly used where it is
necessary to dismantle in order to be cleaned or repaired. Dismantling cost
decreases due to the ease of flange turning and drilling alignment.
.
SOCKET WELD FLANGES
This kind of flange is especially designed for lower small diameters and high
pressures. The pipe is inserted into the flange up to the seat and then is fillet
welded against the cube.
BLIND FLANGES
Blind flanges are utilized for pipe ends, and they bolted to any of the above
flange types.

Application/Usage
A flange is a method of connecting pipes, valves, pumps, and other equipment to form a piping system to convey the water, steam, air, gas and oil. It also provides easy access for cleaning, inspection, or modification.
