What is a spectacle blind used for?
Spectacle Blinds are simple safety devices that are installed between two pipe flanges. During normal operation, the open end is installed as a spacer to allow uninterrupted flow. To stop the flow in the pipeline, the blind end is rotated into place between the flanges.
What is blind in piping?
A blind flange is a solid flange as shown below. 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 flanged so it can be connected to valves or piping).
What is a spectacle flange?
A spectacle flange is a specialty flange made of two metal discs attached in the middle by a small section of steel. Spectacle flanges, also known as spectacle blind flanges, are most commonly used on piping systems that need to be separated regularly or where the flow through the systems is regularly stopped.
How will you identify spacer in field?
Typically a Spade and Spacer will be identified by the word “SPADE” or “SPACER” stamped on the handle, to clearly indicate what is in the line. Additionally it will be clearly marked with its size, rating, standard, material, heat number, Balcombe Stamp, and production traceability code.
Where is blind flange used?
Blind flanges are used to seal the end of piping systems or pressure vessel openings. They are commonly used for testing the flow of gas or liquid through a pipe or vessel, in addition to allowing for easy access to the pipe in case work must be done inside the line.
What are pipe spacers?
Casing Spacers center water and sewer pipes in casings with easy installation, are virtually corrosion proof, and provide insulating protection from a possible electrical shorting between the carrier pipe and casing pipe. No special tools or grease needed, and they are easily bolted on by a single worker.
What is a paddle blind?
Paddle Blinds A Paddle Blind is basically the solid half of a Spectacle Blind. A Paddle Blind is often made from one solid metal disc and will usually have a thin length of metal attached to one end to be used as a handle. A finished assembly will resemble the shape of a paddle, hence the name.
What is the function of spacer?
A spacer (also sometimes called a holding chamber) is a device that makes using an inhaler easier and more effective. It attaches to the inhaler on one end and to a mouthpiece or mask on the other end.
How does the membrane of the mitochondria work?
Those membranes function in the purpose of mitochondria, which is essentially to produce energy. That energy is produced by having chemicals within the cell go through pathways, in other words, be converted.
What does a spectacle blind and spacer do?
What is a Spectacle blind and Spacer Spectacle blind and Spacers are a pressure-retaining device used in the piping/pipeline industry to temporarily or permanently blind (shut) or isolate part of the piping or pipeline system. A spectacle blind is a forged product and combination of a flange spade and a ring spacer in one single product.
What happens when the mitochondria in a cell stop working?
When mitochondria stop functioning, the cell they are in is starved of energy. So, depending on the type of cell, symptoms can vary widely. As a general rule, cells that need the largest amounts of energy, such as heart muscle cells and nerves, are affected the most by faulty mitochondria.
What kind of joint does a spectacle blind have?
Spectacle Blind may have a different type of joint face (RF Raised Face, FF Flat Face, RTJ Ring Joint), depending the type of flange. The Spectacle Blind is usually used on the oil line with two different functions: If the spacer is put in between the flanges, the passage of the fluid is allowed.
