There has to be a pull box between every four quarter bends in a conduit run.
Code states no more that 4 - 90 degree bends in a conduit run between pull boxes.
The 'Stub-up', or 90º bend, Back to Back Bends, Three Bend Saddles, and offset bends.
Conduit bodies are used to provide pulling access in a run of conduit, to conserve space where a full size bend radius would be impractical, to allow more bends to be made in a section of conduit or to split a conduit path into multiple directions.
Bends are made in PVC conduit using a tool known as a heat gun or a heat blanket. If you want to make make accurate and aesthetically pleasing bends without distorting the pipe, the PVC conduit must be heated thoroughly - inside and out. This is achieved using a "heater box," or a "heater blanket." Greenlee tools makes both, specifically for working with PVC conduit. Also available are plugs for plugging the ends of the PVC lengths to be bent, for keeping heat trapped inside the pipe and speeding up the heating process.
All conduit shall not have more than 360 degrees for it's length between either a box, cabinet, or conduit body. Couplings count as a continuation of conduit.
The electrical code states that there will be no more that four quarter bends between junction boxes. Keep in mind when conduit bending that an offset of two 45 degree bends is classed as a 90 degree bend. Offsets between two junction boxes uses up two of the four 90 degree bends allowed. If in a conduit run, the limit of 90 degree bends is utilized, always pull in stranded wire to make the pull go easier.
Per national electrical code you are only allowed 360 degrees which is 4, 90 degree bends before having to use a pull box or termination.

You should use conduit bends when you want to bend a pipe to any angle, either 90 or 30 degree angles. To achieve this, you need to master the maths formulas for bending conduit.

A goose neck pipe can not be bought. It is just a straight piece of electrical conduit when it starts. It is an electrician with a conduit bender or a hickey that bends the conduit into a goose neck configuration.
