What is the function of pipe flanges?

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.

What are the different types of pipe flanges?

Pipe flanges can be divided into eight types based on design. These types are blind, lap joint, orifice, reducing, slip-on, socket-weld, threaded, and weld neck. Blind flanges are round plates with no center hold used to close the ends of pipes, valves, or equipment.

What is the purpose of a pipe?

The purpose of a PIPE is for the issuer of the stock to raise capital for the public company. This financing technique is more efficient than secondary offerings due to fewer regulatory issues with the Securities and Exchange Commission (SEC).

What are flanges in the body?

(flanj) That part of the denture base that extends from the cervical ends of the teeth to the border of the denture.

How are pipe flanges made?

Flanges are manufactured using three main techniques: casting, cutting from rolled plate material, or forging. No matter the technique, the basic flange production includes processing raw materials, then forming them to the appropriate specifications.

What is pipe schedule?

Pipe Schedule (SCH) is a standard that measures the nominal wall thickness of a pipe, given by the ANSI / ASME B36. The pipe schedule number is non-dimensional and depends on the nominal pipe size, internal pipe working pressure, and the material used for the pipe wall.

What are pipe spools?

A pipe spool refers to a section of a piping system that is prefabricated as smaller segments with flanges and fittings. Pipe spools are often prone to corrosion due to their exposure to the elements, water and other natural electrolytes.

Why are piping systems important?

A piping system is crucial to any process plant; hence it needs to be designed with precision and care. The efficiency of a plant highly depends on its ability to transport fluid through the pipes to various equipment that function collectively.

Where are pipe systems used?

Piping systems are used to transport all known liquid or gaseous fluids, for pasty materials or pulp and for fluids in suspension, covering the whole range of pressure and temperature used in industrial applications.

What is threaded flange?

Threaded flanges, also sometimes referred to as companion flanges / screw flanges / NPT flanges, contain a female NPT thread in the center for connection to male NPT threaded piping. The male pipe end is joined to the flange without a weld connection required but can be sealed with a weld if necessary.

What is a flange in industrial piping?

Industrial piping systems have a different type of flange. These flanged pipes have a wide lip that stands several inches or meters away from the edge of the pipe. These pipes will match up with another pipe of the same design. These two pipes will end up bolted together through holes in the flange.

What is a blind flange and how does it work?

Blind flanges allow easy access to the pipeline, as they can be easily unbolted to let the operator execute activities inside the terminal end of the pipe (this is also the reason why the blind flange type is used as manhole for pressure vessels, at times).

What is the difference between reducing and expander flanges?

Reducing flanges, otherwise called reducer flanges, have an opposite function than expander flanges seen above, i.e. they are used to decrease the bore of a pipeline. The bore of the run pipe can be safely reduced by only 1 or 2 sizes (otherwise a solution based on the combination of a butt weld reducer and a standard flange has to be used).

What are the advantages of weld neck flanges?

Another advantage of the welding neck flange is that it can be connected either to pipes and fittings, whereas socket weld flanges suit pipes only.
