It is use to complete change of direction in soil, waste and drain lines in horizontal, vertical and diagonal directions.

Back 18

Bends (elbows)

Front 19

It is use for change of direction (diagonal) and branch connections of soil, waste and drain pipes.

Back 19

Y (wye) branches

Front 20

It is use to join 3 or 4 pipes at perpendicular directions.

Back 20

T (tee) branches

Front 21

made from an alloy of iron, carbon and silicon, with the controlled amounts of manganese, sulfur and phosphorous. This is primarily used for sanitary drain, waste and storm systems.

CAST IRON SOIL PIPE (CISP)

Front 22

CLASSIFICATIONS OF CAST IRON SOIL PIPE

Back 22

1. Class A – Extra Heavy (xh) – is often used for underground applications. 2. Class B – Service weight (SV) – is used for general building installations.

Front 23

is equipped with one hub and one spigot end and used in the installation of plumbing in its full length.

Back 23

Single hub

Front 24

is constructed with a hub on each end so it may be cut into two pieces when a short piece of pipe is needed.

Back 24

Double hub

Front 25

there is no hub on either ends of the pipe, it is used in lieu of the single hub calking of the pipe is difficult.

Front 28

that portion of the pipe which, for a short distance, is sufficiently enlarged to receive the end of another pipe of the same diameter for the purpose of making a joint. It is also known as Bell.
