A cylindrical hollow tube, used to convey water, gas, oil, water, etc, which come in varying materials, thicknesses and lengths. Natural gas and steam pipes up to 750 degrees F are made of carbon steel. Chrome-molybdenum low alloy steel is often used for temperatures above 750 degrees F. Water pipe is most often made of polyvinyl chloride. Some stainless steels, for example grave 311 H stainless, are also used for high temperatures while other stainless steels are used when pipe systems must be kept clean.
Pipe Bushing
Short pipe which has threading on the inside and outside diameter, along with wrench flats, for turning, at one end. Bushings can be used to change pipe sizes when other fittings cannot be used.
Pipe Cap
Fitting to close off the end of a length of pipe.
Pipe Clamp
Designed for spanning wide work, it has a metal pipe with screw clamps and an adjustable stop mounted on the pipe. The clamping mechanism is positioned long the length of the bar to fit the appropriate size of the work with the length of the bar. Fine adjustments and clamping pressures are made by the screw threads on the clamp, which is also called a bar clamp.
Pipe Coupling
Pipe sleeve, which can be joined to other lengths, by being screwed into either end of the pipe, both of which are threaded.
Pipe Cross
Cross shaped fitting which can be used to connect four lengths of pipe.
Pipe Cutter
Apparatus, which consists of a sharp cutter wheel and a set of rollers that can clamp the circumference of any size pipe. The cuter wheel cuts a groove into the pipe when the cutter is clamped in place and rotated around the outside of the pipe. Every time the cutter is rotated around, the cut into the pipe wall gets deeper until it is severed.
Pipe Dope
Compound which, when applied prior to joining, lubricates a pipe joint or seals the pipe threads when the pipe is joined.
Pipe Ell
Plumbing fitting, shaped like an elbow, which allows water to flow in a curve. Also referred to as an ell, it is designed to use with pipe, tubing, conduit, or duct and is available in 90 to 45 degrees.
Pipe Fittings
All parts used for joining pipe and bending or changing direction of piping such as tees, ells, bushings, adapters, couplings, etc.
Pipe Flange
Projecting rim or collar on a wheel or pipe which holds it in place, gives it strength or allows it to attach to another object. Often there are bolt holes circled around the outer edge of the rim, with bolts with nuts holding the two flanges together against a gasket that separates them.
Pipe Hanger
Device which is used to hold piping in place. Hangers support pipes from above and are a necessary part of the piping system, because they keep the pipes functional and intact in spite of any problems.
Pipe Joint
Connecting piece between two lengths of pipe or lengths of pipe and fittings. Joints are threaded, welded, cemented, flanged, etc. depending on the kind of pipe being joined.
Pipe Joint Compound
Compound which, when applied prior to joining, lubricates a pipe joint or seals the pipe threads when the pipe is joined.
Pipe Laser
Laser beamed optical device which is used to align pipes by projecting the beam along the slope of pipe installation and beyond to some distant point. The pipe layer can keep a watch on the alignment of the piping by looking through the viewer to check if there is alignment with the light beam.
Pipe Nipple
Short length of pipe with male threading on each end, used in places where one is needed.
Pipe Plug
Male threaded plug, which seals the end of a run of pipe when fitted into a female threaded fitting. Plug has a slotted head or square head with wrench flats.
Pipe Size
Size of pipe up to 12 inches, after which the pipe size (nps for nominal pipe size) is the outside diameter.
Pipe Sleeve
Sleeve, constructed from a strong and durable material, which is passed through a wall, for the purpose of inserting other pipe through it and, therefore, through the wall.
Pipe Street Ell
Connector ell which has male threads on one end and female threads on the other so that it can connect a male end of pipe to a female end or can change direction without a joint.
Pipe Supports
Any and all devices such as straps, clamps, etc. which are used to hold piping in place. Hangers support pipes from above while spring supports can be used either above or below. Riser clamps support the weight of vertical pipes, while roller supports permit the pipe to move axially. A necessary part of the piping system, they keep the pipes functional and intact in spite of any problems.
Pipe Tee
Fitting which joins three pipe lengths at a single junction.
Pipe Threader, Ratchet
A handle that is usable with a variety of die sizes, with a ratchet that can turn a die, even when it cannot do a full turn. Used with a die, it cuts threads into pipe ends.
Pipe Threader, 3-Way
Handle that has three sized pipe dies to use for cutting threads into pipe ends when the correct size die is fitted to the end of the pipe and the threader is rotated.
Pipe Threads
Increased sealing ability is caused by use of tapered threads, when the pieces are joined and tightened.
Pipe Vise
Vise which grips the outside of a pipe by use of a chain or curved jaws so that it isn't flattened and can be used to hold pipe while cutting or threading and while fitting are installed.
Pipe Wrench
Adjustable wrench, also called a Stillson wrench, has serrated jaw surfaces to grip pipe and a movable jaw, at an slight angle to the fixed jaw, so that the angle increases the jaws' grip on the pipe, when it pivots slightly as force is exerted on the handle.
Contractor whose job is to install piping for steam, cooling, hot water, etc.
System of pipes, which carry fluids over, distances, both great and small.
Pipes, supports, fittings, valves and other components that make up the system for transporting or containing gas or liquid from one place to another.
Piping Area Drawing
Drawing, done by the layout person for the piping system, which shows, to scale, the routing of the piping system using either elevation views or plan and section views.
Piping Codes and Standards
Codes applicable to piping and piping systems are established by local and state laws. Materials are covered by American Society for Testing and Materials (ASTM) Standards with other regulations being set by American Society of Mechanical Engineers (ASME), American Petroleum Institute (API), American Water Works Association (AWWA), American National Standards Institute (ANSI), American Welding Society (AWS), Manufacturers Standardization Society of the Valve and Fitting Industry (MSS), Plastics Pipe Institute (PPI), Copper Development Association (CDA) and the Uni-Bell PVC Pipe Association.
Piping or Tubing, Copper
Tubing or piping either thin Type M, medium Type L and heavy wall Type K, which can be either rigid, called Drawn Temperature Pipe or flexible, called Annealed Tubing, all of which is made from copper alloy. The outside diameters range from ¼ inch to 12 inches with connections made of compression fittings, solder joints and flare fittings with threaded joints normally used for piping.
Piping Isometric Drawing
Three-dimensional drawing that shows the layout, sizes and dimension of the piping system of a structure.
Piping, PVC
Polyvinyl chloride, a lightweight, resilient, chemical resistant, strong and durable thermoplastics, with an long lifespan, made into piping which is often used for cold water systems and where chemicals are found. There is bell and spigot pipe, with a bell on one end, which has an internal elastomer seal to hold the lubricated plain end of the next piece of pipe, by making a fluid-tight joint. Solvent cement joint pipe joins the ends by applying a primer to soften the surface of the material, with the solvent cement being applied to the pipe end and the inside of the fitting end, then inserting the pipe into the fitting using a twisting motion to spread the solvent cement. The cement cures rapidly and the joints fuse together.
Piping Schematic
Schematic drawing, which shows the routing of the piping system of a structure, without showing the piping lengths or giving dimensions.
Solid cylinder within a cylinder pumping and compressing fluid as it moves back and forth.
