Why use flanges?
flange is For connecting pipes to each other, to valves, to fittings, and special items such as filters and pressure vessels. … flanges are bolted, and sealing is usually accomplished using gaskets or other methods.
Why are pipe flanges important?
flange is A method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides convenience for cleaning, inspection or modification. Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.
What is the main purpose of the flange?
The main purpose of using flanges is to Two separate openings for connecting devices, e.g., two pipes, valve fittings on one pipe and any equipment fittings. It ensures the movement of petroleum products, natural gas or any other liquid product inside the pipeline without any obstruction or leakage.

Why use slip flanges?
Sliding flange is Suitable for low pressure applications And easy to install and weld to different pipes. Additionally, welding helps reduce manufacturing costs. Slip-on flanges do not require a large longitudinal space in the installation pipeline.

What is a sliding flange?
Sliding on the flange is essentially Ring placed on pipe end, the flange face extends far enough from the end of the pipe to apply a weld on the ID. … Sliding on flanges can also be used for lap flanges if a Type B or C stub end is used.
What is a lap flange?
The lap flange is two-component assembly, with a stub end with a lap ring flange. The stub end is then butt welded to the pipe and the flange ring can be rotated to align with the mating flange. This type of flange connection is especially useful for large or difficult-to-adjust flanges.

What is the difference between ASME and DIN flanges?
RE: DIN Standard and ASME Flange Ratings
DN is not short for DIN, but a metric unit Same as ND for ASME pipes and fittings. So DN 150 is directly equivalent to 6″ pipe. On the other hand, PN is the maximum pressure rating in barg. This applies to groups 2.5, 6, 10, 16, 25, 40, 64, 100.
What are the advantages of flanges?
Use of flanges Allows one person to easily repair and maintain plumbing systems. Instead of taking out the whole pipe for inspection, a small section of the pipe can be inspected with the help of the flange to find the fault. Flanges allow easy inspection and cleaning of pipes.

How do I know what grade my flange is?
The pressure rating of the flange will be given in rating.class, followed by a dimensionless numberis the name of the pressure-temperature class as follows: Class 150 300 400 600 900 1500 2500. Different names are used to denote pressure levels.
What is the grade of the flange?
The term « flange grade » (or grade) refers to Maximum pressure (in psi or bar) that the flange can withstand at elevated temperature. Flanges with a higher rating (class) are stronger than flanges with a lower rating because they are subjected to more stress as temperatures rise.
How many types of face flanges are there?
This 6 Available flange face types are flat (FF), raised (RF), ring joint (RTJ), lap joint, male and female (M&F), tongue and groove (T&G). Flanges on different faces require different gaskets and must not mate to prevent joint leakage.
