Spray nozzle mounting for receiving fluid from distribution pipe

A method of adapting a nozzle assembly from a first fluid pipe to a second fluid pipe, the first fluid pipe having a larger diameter than the second fluid pipe, the nozzle assembly comprising a lower clamp, a first upper clamp, and a stem positioned in a receiver located in the lower clamp, the method comprising:

• a) decoupling the first upper clamp from the lower clamp, the first upper clamp and the lower clamp configured for cooperatively engaging the first fluid pipe;
• b) removing the lower clamp from the first fluid pipe, which includes removing the stem from a fluid outlet of the first fluid pipe and removing the stem from the receiver of the lower clamp;
• c) inserting an adapter into the lower clamp, inserting a second stem in the adapter, and orienting an interior rib of the second stem in the direction of travel of the nozzle assembly during a spraying operation, wherein the adapter is configured for cooperatively engaging the second fluid pipe;
• d) coupling the lower clamp to the second fluid pipe including inserting the second stem into a fluid outlet of the second fluid pipe;
• and
• e) coupling a second upper clamp in place of the first upper clamp, the second upper clamp configured for cooperatively engaging the second fluid pipe and the lower clamp.

A method of adapting a nozzle assembly to a first fluid pipe or a second fluid pipe, the nozzle assembly comprising a lower clamp, a first upper clamp, a second upper clamp, a seal an adapter and a stem, the method comprising:

• selecting one of the first upper clamp shaped to at least conform to and engaged with the first fluid pipe and the second upper clamp shaped to at least conform to the second fluid pipe;
• selecting the adapter, the seal and the lower clamp, wherein the adapter includes a lower surface shaped complementary to, and mounted in engagement with, a clamping surface of the lower clamp, the seal being received on the stem and separable from the adapter and the stem includes an interior rib oriented in a direction of travel of the nozzle assembly during a spraying operation;
• and
• coupling the first upper clamp and the lower clamp with the first fluid pipe or coupling the second upper clamp and the adapter and lower clamp with the second fluid pipe, wherein a diameter of the second fluid pipe is smaller than a diameter of the first fluid pipe.
