NEC allows four quarter bends between junction boxes and conduit bodies for a total of 360 degrees. You can have more than four bends, but all of the degrees of the bends can not add up to more than 360 degrees.
The electrical code states that there shall not be more than 4 90 degree bend between pull boxes. Keep in mind that an offset going into a box is equal to one 90 degree bend.
CEC, 4 - one quarter bends.
360 degrees cummulative per NEC
The electrical code states that there shall be no more than four 90 degree bends in a conduit length between pull boxes. This equals 360 degrees. The first scenario 90 + 90 + 45 + 45 + 45 + 45 = 360 degrees so that conduit run is acceptable. The second scenario 90 + 90 + 30 + 30 + 30 + 30 +30 = 330 degrees so this combination is also acceptable.
The electrical code states that there will be no more that 4 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.In a conduit run between J boxes the number of bends can not exceed 360 degrees.The electrical code allows four 90 degree bends between pull boxes.

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.
A pull box is a junction box that is placed in long conduit runs to make the pulling in of the wires easier. The code only allows 4 one quarter bends between pull boxes. If the conduit run incorporates more that 4 bends then a pull box has to be inserted into the run. The code allows up to the "equivalent" of four quarter bends or 360 degrees total before pull box is required.
Code states no more that 4 - 90 degree bends in a conduit run between pull boxes.
There has to be a pull box between every four quarter bends in a conduit run.
Yes. You have to have a pull box every 4 90s or every 100ft. Which ever comes first.
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.

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.
When exist a junction box EMT, conduit must be supported within 18 inches.
It is easier that you bend the conduit around the beam or pierce the conduit throough the beam, depending on how big the conduit is.
