A pipe clamp is a type of clamp often employed in woodworking, piping or cabinet shops. When referring to woodwork or cabinet shops, pipe clamps are usually composed of commercially manufactured clamp heads or "jaws" and a length of common threaded pipe. The capacity of the clamp is determined by the length of the pipe used. When referring to piping, pipe clamps are used to connect the pipe to the pipe hanger assembly.
In woodwork, a pipe clamp uses clamp heads produced commercially by numerous manufacturers. They are available in various diameter sizes, commonly ½”or ¾”, suited to the same diameter piping. The pipe is usually threaded on both ends. One head is fixed on the pipe by spinning it onto standard pipe threads. This head includes the screw mechanism for tightening the clamp. The other, movable, head slides onto the other end of the pipe. This head has a mechanism, often a series of movable “clutches” which allow it to slide along the pipe when setting up the clamping operation but which lock onto the pipe when clamping pressure is applied.
Pipe clamps serve a similar purpose to bar clamps but are generally less expensive to purchase and have a versatility derived from the ability to use a variety of lengths of pipe to suit one's needs. The same clamp heads might be switched over from a two-foot length of pipe to a twelve-foot length as the project at hand dictates. Having threads at both ends of the pipe also allows the use of pipe couplings, joining two lengths of pipe to extend the length of the clamp.
In piping, a pipe clamp is a bottled attachment that clamps around the pipe. The clamps can be manufactured with black or galvanized finishes.
A common use of pipe clamps in woodworking is for edge gluing; several boards being joined edge to edge to produce a wider surface such as a table top or cabinet components. In this case several pipe clamps will be set up on the workbench so that clamping pressure can be applied evenly along the length of the boards being joined. Pipe clamps can be used to assemble the four sides of boxes or cabinets.
As with most other forms of clamps, a wide variety of uses might be found.
A lathe is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis.
A clamp is a fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. In the United Kingdom the term cramp is often used instead when the tool is for temporary use for positioning components during construction and woodworking; thus a G cramp or a sash clamp but a wheel clamp or a surgical clamp.
A table saw is a woodworking tool, consisting of a circular saw blade, mounted on an arbor, that is driven by an electric motor. The drive mechanism is mounted below a table that provides support for the material, usually wood, being cut, with the blade protruding up through the table into the material.
A bandsaw is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw. The minimum radius of a curve is determined by the width of the band and its kerf. Most bandsaws have two wheels rotating in the same plane, one of which is powered, although some may have three or four to distribute the load. The blade itself can come in a variety of sizes and tooth pitches, which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic. Band saw is recommended for use in cutting metal as it produces much less toxic fumes and particulates when compared with angle grinder and reciprocating saw.
A biscuit joiner or biscuit jointer is a woodworking tool used to join two pieces of wood together. A biscuit joiner uses a small circular saw blade to cut a crescent-shaped hole in the opposite edges of two pieces of wood or wood composite panels. An oval-shaped, highly dried and compressed wooden biscuit is covered with glue, or glue is applied in the slot. The biscuit is immediately placed in the slot, and the two boards are clamped together. The wet glue expands the biscuit, further improving the bond.
A hose clamp (hose clip,hose lock or Jubilee Clip (UK)) is a device used to attach and seal a hose onto a fitting such as a barb or nipple.
A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. In instances where two pipes made of dissimilar materials are to be joined, the fittings will be made of one or more compatible materials appropriate for the connection. Compression fittings for attaching tubing (piping) commonly have compression rings, called ferrules or olives, in them, and are sometimes referred to as flareless fittings. There are also flare fittings that do not require ferrules/olives.
A chuck is a specialized type of clamp used to hold an object with radial symmetry, especially a cylinder. In a drill, a mill and a transmission, a chuck holds the rotating tool; in a lathe, it holds the rotating workpiece.

A vise or vice is a mechanical apparatus used to secure an object to allow work to be performed on it. Vises have two parallel jaws, one fixed and the other movable, threaded in and out by a screw and lever. The jaws are often flat but may have grooves, adapt to the shape of the workpiece or be custom made.
A dowel is a cylindrical shape made of wood, plastic, or metal. In its original manufactured form, a dowel is long and called a dowel rod, which are often cut into shorter dowel pins. Dowels are commonly used as structural reinforcements in cabinet making and in numerous other applications, including:
An F-clamp, also known as a bar clamp or speed clamp, is a type of clamp. The name comes from its "F" shape. This tool is used in woodworking while more permanent attachment is being made with screws or glue, or in metalworking to hold pieces together for welding or bolting. F-clamps are similar to but distinct from C-clamps and pipe clamps.
A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.
Pocket-hole joinery, or pocket-screw joinery, involves drilling a hole at an angle — usually 15 degrees — into one work piece, and then joining it to a second work piece with a self-tapping screw.
A fitting or adapter is used in pipe systems to connect sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating fluid flow. These fittings are used in plumbing to manipulate the conveyance of fluids such as water for potatory, irrigational, sanitary, and refrigerative purposes, gas, petroleum, liquid waste, or any other liquid or gaseous substances required in domestic or commercial environments, within a system of pipes or tubes, connected by various methods, as dictated by the material of which these are made, the material being conveyed, and the particular environmental context in which they will be used, such as soldering, mortaring, caulking, plastic welding, welding, friction fittings, threaded fittings, and compression fittings.
Buttress thread forms, also known as sawtooth thread forms or breech-lock thread forms. are screw thread profiles with an asymmetric shape, having one square face and the other slanted. They are most commonly used for leadscrews where the load is principally applied in one direction. The asymmetric thread form allows the thread to have low friction and withstand greater loads than other forms in one direction, but at the cost of higher friction and inferior load bearing in the opposite direction. They are typically easier to manufacture than square thread forms but offer higher load capacity than equivalently sized trapezoidal thread forms.
Tube bending is any metal forming processes used to permanently form pipes or tubing. Tube bending may be form-bound or use freeform-bending procedures, and it may use heat supported or cold forming procedures.
A tire changer is a machine used to help tire technicians dismount and mount tires with automobile wheels. After the wheel and tire assembly are removed from the automobile, the tire changer has all the components necessary to remove and replace the tire from the wheel. Different tire changers allow technicians to replace tires on automobiles, motorcycles and heavy-duty trucks. New tire and wheel technology has improved certain tire changers to be able to change a low profile tire or a run-flat tire.
Heat fusion is a welding process used to join two different pieces of a thermoplastic. This process involves heating both pieces simultaneously and pressing them together. The two pieces then cool together and form a permanent bond. When done properly, the two pieces become indistinguishable from each other. Dissimilar plastics can result in improper bonding.
A pipe support or pipe hanger is a designed element that transfer the load from a pipe to the supporting structures. The load includes the weight of the pipe proper, the content that the pipe carries, all the pipe fittings attached to pipe, and the pipe covering such as insulation. The four main functions of a pipe support are to anchor, guide, absorb shock, and support a specified load. Pipe supports used in high or low temperature applications may contain insulation materials. The overall design configuration of a pipe support assembly is dependent on the loading and operating conditions.
