🔥Explanation of Charted Fl**ges:
💥Pipe Fl**ges:
Fl**ges are piping components bolted together using gasket in between two fl**ges as a sealing material. Fl**ges are used to connect pipes with each other, connect pipes to fl**ged valves, connect pipes to fl**ged fittings, and connect pipes to fl**ged piping
✨Blind Fl**ge:
The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used. (A nozzle is typically a pipe coming out of a vessel and is usually fl**ged so it can be connected to valves or piping).
🌟Welding Neck/ Welded Fl**ges:
A welding neck fl**ge features a long tapered hub that can be welded with a pipe. This fl**ge type is used, normally, in high-pressure and high/low temperatures applications that require an unrestricted flow of the fluid conveyed by the piping system
⚡Slip on/ SO Fl**ges:
They are mainly used for fluids at low pressure or with little risk of leakage. It is very common to find these fl**ges today in cooling water lines, fire fighting water lines, low-pressure compressed air lines, and process lines for substances such as steam, oil, gas, condensates, etc.
💨Socket Weld Fl**ge:
Socket-weld pipe fl**ges are typically used on smaller sizes of high pressure pipes. These pipe fl**ges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe.
💢Threaded/ Screwed Fl**ge:
Threaded fl**ges are used with pipes that have external threads. The benefit of these fl**ges is that it can be attached without welding. Threaded fl**ges can be fitted to pipes of various sizes without welding and this is one chief benefit for which these fl**ges are highly demanded.
🔅Lap Joint/ Steel Lap Joint Fl**ges:
Lap joint pipe fl**ges slide directly over the pipe and are most commonly used with stub end fittings. Lap joint fl**ges are usually used in low pressure applications and are not suitable when there are high loads on the fl**ge pair. Some types of piping require the use of lap joint fl**ges. For example, metallic pipe that has been plastic lining may have lap joint fl**ges
🟡Plate Fl**ges:
Plate Fl**ges are used to seal the end of pipelines, valves or other connection. With high tensile strength, these steel plate fl**ges are available with a raised face and back ups for easy installation.
💥Reducing Fl**ges:
A reducing fl**ge consists of a fl**ge with one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the fl**ge will have dimensions of the larger pipe size. Reducing fl**ges are used in pipe-to-pipe connections. Reducing fl**ges are a little easier to bolt up than non-reducing fl**ges. They provide the most perfect solution when you need to connect different size fl**ges. These fl**ges are available in all types and pressures. Reducing fl**ges are fixed by welding, gluing or clamping fl**ges of equal dimensions provided with different connecting pieces. They offer the simplest and least expensive method of mating two different sized fl**ges.
💦DIN and ANSI Fl**ges:
The American National Standards Institute (ANSI) is a nongovernment, nonprofit organization that coordinates U.S. industry standards with international standards so that U.S. products can reach the global market. In essence, ANSI serves as an accreditation body for standards developed by other organizations, companies, consumer groups, and government agencies.
The Deutsches Institut für Normung (DIN), or the German Institute for Standardization, serves a similar function. However, DIN is a government organization that embodies German concerns within the framework of European and International standards. DIN has a wide reach, and over 30,000 DIN standards provide comprehensive coverage for various products and technologies.
🔥Forged Steel Fl**ge:
Forged fl**ges are used as a connection component for pipes, valves, pumps and other equipment to form a pipework system. They provide easy access for cleaning, inspection, modification or repairs.
🌟Metal Fl**ge:
A fl**ge is a forged or cast ring of steel designed to connect mechanically sections of pipe or join pipe to a pressure vessel, pump, valve or any other piece of equipment.
🔅Long Weld Neck Fl**ge:
Long Weld Neck Fl**ges are like weld neck fl**ges, except for the neck, which is extended and acts like a boring extension. Long weld neck fl**ges can be used in high pressure industrial applications, as well as high temperature situations. They are often utilized in the oil and gas or petrochemical industries.
✔Ring Joint Fl**ge:
A Ring type joint fl**ge (RTJ) is a machined metallic ring with a deep groove cut into its face. This groove rests a metal ring which gets compressed when the connecting bolts of the fl**ge are tightened. This compression results in a leak-proof, close-fitting seal on the pipe or connection. Ring-Type Joint (RTJ) The Ring Type Joint fl**ges are typically used in high pressure (Class 600 and higher rating) and/or high temperature services above 800°F (427°C). They have grooves cut into their faces which steel ring gaskets.
⚡ASME Fl**ges:
ASME is abbreviations of the American Society of Mechanical Engineers, a non-profit and private organization created for bringing uniformity in voluntary standards used in engineering and industrial disciplines. The ASME is mainly focused on setting codes and standards for mechanical devices. They founded in 1880, after the numerous steam boiler and pressure vessel explosion in various parts of the world.
💨ASTM Fl**ges:
This was established in 1902, ASTM International is one of the world's largest international standards developing organizations. At ASTM International, producers, users, consumers, and others from all over the world join together to develop voluntary consensus standards. ASTM standards are developed under a process that embraces the World Trade Organization Technical Barriers to Trade Agreement principles. The ASTM standards development process is open and transparent, allowing individuals and governments to participate directly, and as equals, in a global consensus decision.
💥Pin Type Fl**ge:
Bush pin type fl**ge is used for slightly imperfect alignment of the two shafts.
This is modified form of the protected type fl**ge coupling. This type of coupling has pins and it works with coupling bolts. The rubber or leather bushes are used over the pins. The coupling has two halves dissimilar in construction. The pins are rigidly fastened by nuts to one of the fl**ge and kept loose on the other fl**ge. This coupling is used to connect shafts which have a small parallel misalignment, angular misalignment or axial misalignment. In this coupling the rubber bushing absorbs shocks and vibration during its operations. This type of coupling is mostly used to couple electric motors and machines.
✨Puddle Fl**ges:
Puddle Fl**ges ensure a watertight and pressure-tight seal where pipes pass through concrete walls of any structure or building. When a pipe is required to pass through a wall or concrete structure it is usually cast at the point of construction. The concrete will not bond to the pipe and will usually shrink during curing, leaving an ingress path along the outside of the pipe allowing materials such as water, gases and hydrocarbons to pass through the structure or building.
🪂Split Fl**ges:
A split fl**ge is a type of fl**ge that can be easily installed on pre-existing piping. Because it is made of two parts, split fl**ges are used to reinforce weakened areas of piping, or to add an attachment in places conventional fl**ges cannot. Split-fl**ge fittings use rubber O-rings to seal joints and contain pressurized fluid. The O-ring sits in a groove on the fl**ge, and then mates with a port’s flat surface. The fl**ge is then attached to the port with four mounting bolts. The bolts tighten downward onto the clamps of the fl**ge, thereby eliminating the need for large wrenches to connect the components of large-diameter tubing.
🌟Cast Fl**ges:
The advantages of fl**ges manufactured by the casting, has lower costs of production, the ability to make more intricate parts at lower costs, as well as having no true upper limit on size when it comes to your part. There are, however, some drawbacks to cast iron fl**ges. The most important of these being how susceptible they are to internal defects, Due to this, cast fl**ges are not suitable for high pressure applications or applications in which the probability of corrosion is high. Despite advancement of casting technology and computer optimization of the casting process and designs, it is still difficult to meet the standards required for petrochemical industry applications.
🟡Or***ce Fl**ge:
The function of the or***ce fl**ge is to measure the rate of the flow of the commodity through the piping system. Or***ce fl**ges are easy to recognize because they have a hole drilled through the face of the fl**ge perpendicular to the pipe. They also have an additional set of bolts called jack screws.
💢PTFE lined reducing Fl**ge:
It is the most cost effective way to transact between the pipes. This is also a good alternative to connect the various diameters pipes together. It can be used in Oil & Gas Industries, Chemical Industries etc.
💨Fl**ge Connector:
A fl**ge connector is a device that allows the connection of many types of hoses and fittings on to a fl**ged pipeline. Typically manufactured from stainless or high-carbon steel, a fl**ge connector is connected to a fl**ged pipe with bolts, and a gasket is sandwiched between the pipe fl**ge and the connector. Common in manufacturing facilities, a fl**ge connector is often used to allow a smaller and more manageable hose to be split off from a large feeder pipeline. A fl**ge-type connector can also be used to block off a pipeline.
