This is used in applications for nonferrous construction:

This type of pipe is commonly used for water, steam, oil, and gas:

Joints between pipes, fittings, and valves may be screwed or flanged but not welded or soldered.

Plastic pipe is lightweight and corrosionproof, but typically is not resistant to chemicals.

This type of pipe is commonly used for water or gas service, and also as soil pipe:

These types of pipes are generally connected with bell and spigot joints or flanged joints:

When dimensioning piping drawings, you give the lengths of all runs of this type:

When dimensioning piping drawings, it is not necessary to indicate the size of each pipe.

Copper tubing is not suitable for process work, for plumbing, or heating systems.

Single-line drawings show the centerline of the pipe.

Axonometric drawings are seldom used in piping drawings.

In this type of drawing, vertical pipes may be revolved into the horizontal plane:

Copper pipe is brittle, and settling can cause fracture unless the joints are sufficiently flexible.

In a developed piping drawing, horizontal pipes may be revolved into the vertical plane so the entire installation can be shown on one plane.

This type of drawing shows two lines representing the pipe diameter:

Brass and copper pipe is used in plumbing for supply, soil, waste, drain, and vent lines.

Piping may also be shown in orthographic projection.

PVC joints are made with flared joints or solder joints.

Valves are used to stop or regulate the flow of fluids in a pipeline.

Brass and copper pipe should be joined with fittings of copper-base alloy to avoid corrosion.
