Pipe flanges are protected from corrosion by means of electrolysis,with dielectric flanges. The piping system is electricaly insulated by what is called a sacrificial anode. A bag of readily corrodable metal is buried in the ground with a wire running from the pipe to the bag so that the sacrificial anode will corrode first. If any electrical current charges the pipe it also serves as a ground.

How can flanges be classified based on pipe attachment?
Flange joint is one of the methods of pipe joints. Piping and flanges are classified in different ways based on pipe attachment, Pressure-Temperature (PT) rating, facing, face finish. Below are the flanges based on the pipe attachments.Classification of flanges based on pipe attachment1) Slip-on Flanges:These flanges are welded on inside as well as outside to the pipe. They are generally forged type with Hub. They can also be fabricated from plates but without Hub.2) Socket-Weld Flanges:These Flanges are welded only on outside of the Pipe. They are usually used in small bore piping where the piping specification is socket weld. They are not used in severe services due to stagnation of fluid at the socket. Socket welded flanges shall be specified with connection pipe thickness to ensure proper bore dimensions.3) Screwed/Threaded Flanges:These Flanged are screwed onto outside diameter of the Pipe. They are used at locations where welding is not allowed. They are used in temperature range of 250 Deg to -45 Deg. The threads can be NPT (Nominal Pipe Threads) or BSPT (British Standard Pipe Threads) as required in the Piping specification.
Are flanges designated by schedule?
If your talking pipe flanges, they are designed by pressure at certain temps. 150lb is standard, and 300lb is for steam applications.
Why are regular orifice flanges installed in a pipe?
To provide taps for instrumentation
Which substance is used to make iron electrically insulated?
ceramic wire....
Can you run insulated wires in a conduit pipe?
Except for the ground wire they must be insulated.
What are the different types of toilet flanges available for installation in a bathroom?
There are primarily two types of toilet flanges available for installation in a bathroom: PVC flanges and cast iron flanges. PVC flanges are made of plastic and are commonly used in newer homes, while cast iron flanges are more durable and are typically found in older homes. Both types of flanges serve the same purpose of connecting the toilet to the drain pipe.
What is pipe shoe for hot insulated pipe lines?
A pipe shoe for hot insulated pipe lines is a supportive device that is used to anchor and support the weight of the pipe, while also providing thermal insulation. It is typically designed with a base that allows for easy installation onto a structure or pipe support system, and is constructed with materials that can withstand high temperatures. The pipe shoe helps to prevent excessive heat transfer and damage to the insulated pipe.
Does the toilet flange go on the inside or outside of soil pipe?
Toilet flanges OUTSIDE of the pipe including cast iron and brass to lead
What is a pipe spool?
A pipe spool refers to a prefabricated section of a piping system. This includes the pipe, fittings and flanges that are pre-assembled. They are pre assembled because this can be done in a controlled environment.
What are the different types of toilet flanges available in the market?
The different types of toilet flanges available in the market include PVC, ABS, cast iron, and stainless steel. These flanges are used to connect the toilet to the drain pipe and provide a secure seal to prevent leaks.
What is the basic definition of a pipe flange What exactly is the role it plays in a pipe assembly?
A pipe flange is used in the assembly of pipe to pipe or other things like valves, elbows etc. The flanges are bolted together, creating several lengths of pipe or other assemblies.
What is bolt up pattern on pipe flanges?
The bolt-up pattern on pipe flanges refers to the specific arrangement and sequence in which bolts are tightened to secure the flanges together. This pattern is typically designed to ensure even distribution of stress and to prevent misalignment or warping of the flanges. Commonly, a star or crisscross pattern is used, starting from the center and moving outward, to achieve uniform compression of the gasket. Proper bolt-up procedures are crucial for maintaining a leak-proof seal in piping systems.
