For pipes to stay where they are installed, they are usually connected to support systems that keep them in place. Pipes can be supported from below using brace supports, from above using pipe hangers and, for pipes running up and down, with clamps that adheres them to the wall. There are many different types of pipe supports in these categoriess

Pipe hangers, springs and supports are typically part of a large industrial or complex piping system. These are generally larger pipelines, large-scale sprinkler systems and water lines. All spring hangers and supports need to work as a unit to adequately support the pipe. Due to enormous weight and pressure, as well as change in temperature, if the support measures aren't calibrated correctly, the pipe can collapse and rupture. Sizing hangers and supports requires combining a variety of calculations.

Pipes clamps help keep pipes in place whether on the ground, attached to the ceiling or up against a wall.
For pipes to stay where they are installed, they are usually connected to support systems that keep them in place. Pipes can be supported from below using brace supports, from above using pipe hangers and, for pipes running up and down, with clamps that adheres them to the wall. There are many different types of pipe supports in these categoriess. Pipe Hangers
Because most above-ground pipes in residential and commercial buildings are installed overhead, pipe hangers are the most common form of pipe supports. These come in numerous styles; the most common types are strap-style, hook-style, channel-style and clamp-style. Strap-style pipe hangers are made of a thin, flexible piece of metal or other material that wraps around the pipe and is then attached to the ceiling. Hook-style pipe hangers are made into a J-shape, the longer end of which is attached to the ceiling; the pipe rests on the hook. Channel-style pipe hangers are very wide J-hooks and can help conceal the pipe as it supports it.
Pipe Risers Pipes that rest against the ground typically rest on risers that help keep them secure to the ground. Pipe anchors are rises that rigidly restrict any vertical movement caused by the pipe's internal flow or external forces. Shock-absorbing pipe supports allow some movement by the pipe but swallow any vibrations or excess movement; they are good for pipes that move a great deal as a result of high-feed or inconsistent flow. Insulated pipe supports minimize energy dissipation and reduce the effects of differing temperatures that occur at the support.
Vertical Clamps
 There are a number of different pipe clamps that can be used to attach vertical pipes to walls. Saddle clamps use top and bottom plates that are secured by bolts and are designed to absorb vibration and heat from high-pressure feed. Gang clamps are made of an angled piece of strong metal, the ends of which are bolted to the wall. They are useful for attaching several pipes within close proximity of each other because of their minimal use of space. Strap-style pipe hangers can also be used to attach vertical pipes to the wall in the same way they can be used in overhead areas.
General Pipe Clamps
There are also hundreds of different types of pipe clamps that can be used to ad-here pipes to other objects. These pipe clamps typically use some kind of bolt mechanism; they may support the pipe by attaching to themselves or they may be bolted to a wall or elsewhere.

Pipe fittings are small and often standardized accessories to drain, waste, and vent (DWV) systems, covering many components that connect pipe ends for in-line, offset, multi-port, and mounting configurations. They are manufactured from a wide variety of materials for the transport of an equally wide variety of solids and fluids. Fitting cross sections are often, but not necessarily, circular in shape to mate with the pipe sections they are connecting; systems are typically configured with straight sections connected by fittings or specially-formed connections and joints. Pipe fitting construction and material specifications are application-dependent; user consultation with fitting suppliers is typical for optimization of component selection. When specifying pipe fittings, size is the key parameter to consider. Common types of pipe fittings include adapters, pitless adapters, bulkhead fittings, caps, compression fittings, rigid couplings, flexible couplings, cross or 4-way fittings, 90 degree elbows, 45 degree elbows, reducing elbows, end bells, expansion joints or couplings, ferrules, flanges, nipples, offset fittings, plugs, concentric reducers, eccentric reducers, returns or traps, side outlet elbows, side outlet tees, standard tees, reducing tees, bullhead tees, unions, standard wyes, and reducing wyes.  Some pipe fittings have a swivel feature that allows one or more fitting ends to rotate or swivel.
