What is a flanged fitting?
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.
How are fittings attached to plastic pipes?
There are two ways for connecting PVC pipe and fittings together for a structural project. They are the PVC solvent (cement) method, and the fastener connect technique. Both versions work well, but we ALWAYS recommend using PVC cement, as it is the most secure and permanent answer.
What is a Van Stone flange?
Van Stone Flange – This is a two piece flange with a rotating ring that makes bolt alignment simple. This flange has one female threaded end to connect to a male threaded fitting or nipple.
What is PVC flange?
Sch 80 PVC Flanges Flanges are fittings that connect to pipes to allow the attachment of accessories and other items, stop the flow or increase the strength of the pipe. These discs create a tight seal when pressing two surfaces together using bolts, clamps, edges or a compressive force.
Where should a flanged fitting be loosened first?
By reaching over the pipe to first loosen flange bolts on the far side, if any pressure happens to be inside the pipe, it should leak there first, venting the pressure in a direction away from you.
Is flange a standard?
A flange standard lays down the dimensions, surface finish, facing type, marking, material and technical specifications for flanges. National flange standards in Europe have largely been superseded by the European EN 1092 series.
What is another name for a Van Stone flange?
The process of manufacturing a pipe spool with both flanges rotating without the use of conventionally welded or screw threaded collars is known as the “Conrac” or more properly the “Van Stone” system.
What is lap joint flange?
A lap-joint flange is a two-component assembly, with a stub end that has a lap-joint ring flange placed over it. This type of flange connection is particularly useful for large or hard-to-adjust flanges. The lap joint flange can be used in sizes and pressure classes similar to that of a weld-neck flange.
What is a flange Plunger used for?
The flange plunger is commonly known as a toilet plunger. This type of plunger is designed for unblocking toilets. The flange is the section of rubber which protrudes from the bottom of the cup. The flange folds in and out of the cup, allowing the plunger to be used as a cup plunger if required.
What are flange insulation kits?
A flange insulation kit consists of a flange gasket, bolts and insulating sleeves used to install a leak-proof flange. The insulating sleeves used in the kit are manufactured of a high-density, polyethylene plastic that prevents an electrical charge from dissimilar metals from causing corrosion and ultimately weakening and breaking a flange bolt.
What are specialty flanges?
A special flange is a component with a flanged joint that has the same bolting structure as a standard flange, but a special flange has its own characteristics. There are still a number of specialty flange such as: Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings.
What are PVC specialty fittings?
Specialty PVC fittings refer to non-standard PVC fittings that connect PVC pipe in unique ways that you normally cannot do with plumbing fittings from the hardware store. Typically used for PVC structures, specialty fittings are an easy way to build quick PVC-pipe based solutions.
