1 Pipe mount
1.1 The pipe mount should have adequate strength to endure the reaction force, which is applied toward
the opposite direction of the discharge and along with the center line of the discharge port.
1.2 Pressure loss in the pipe mount decreases the discharge capacity and destabilize the product
operation. Install the product vertically at a position as close as possible to the boiler body or the
header, as well as accessible for maintenance and inspections.
1.3 The inner diameter of the pipe mount should be equal to or larger than that of the product inlet.
2 Discharge pipe
2.1 Install a discharge pipe and drip pan elbow to ensure that the product is free from the stress caused
by the thermal expansion of the equipment or by the thermal expansion/compression of the discharge
pipe.
2.2 The inner diameter of the discharge pipe should be equal to or larger than that of the product outlet to
avoid backpressure.
