More Great Information on Pipe Tee:

Moisture and Cold Pneumatic Air Cylinder by Saphia

If product is blown into a cold pipeline, the inside surface could be wet as a result of condensation. This can occur in pipelines subject to large temperature variations, particularly where there are pipe runs outside buildings. If air drying is not normally necessary, the problem can be overcome by trace heating of exposed sections of the pipeline or by blowing the conveying air through the line to dry it out prior to introducing the pneumatic product. Lagging may be sufficient in some cases.

In normal operation, the delivery temperature of air from a Roots-type blower could be 80 Degrees C higher than the inlet temperature. This means the volumetric flow rate and the conveying air velocity will be 25 to 30 percent greater than the value at ambient temperature. On startup, the air will be relatively cold for conveying the product and, if the resulting conveying air velocity is below that necessary for the product, the pipeline could block.

Since air density increases with temperature decrease, it is essential that air requirements be based on the lowest temperatures likely. If this results in excessively high conveying air velocities during normal operation, then it will be necessary to control the air flow rate to the conveying line. Variable speed control of the air mover, choked flow nozzles in a by-pass air-supply line or discharge of air to atmosphere via a control valve could be considered.

Product in the line
If the pipeline is not purged during a plant shutdown, some product could be left in the line. On startup it's important to blow air through the pipeline before product is introduced. If the reference value of pressure drop for air blown through the pipeline is known, it can be compared with the air-purge value. If the actual pressure drop is significantly higher than the empty-line value, product may still be in the pipeline. It's also good practice to purge the line and check the pressure drop before shutdown.

Unexpected shutdown
If conveying stops unexpectedly due, for example, to a power-supply failure, it may not be possible to start the system again, particularly if there is a large vertical lift. If the bend at the bottom of the vertical section is taken out to remove the product, it may be possible to purge the line clear.

If this is a common occurrence for a plant, an air receiver can be installed between the air mover and product feeder. If the product feed into the pipeline stops at the instant the power fails, the air stored in the receiver could be sufficient to clear the line of product. Alternatively, a parallel line with valved connections to the pipeline could be fitted so that the line could be cleared slowly from the end, one section at a time.

When good systems go bad
If a system that has worked well for a long time starts to develop blockage tendencies, feeding device wear may be the cause. If air leakage across the feeding device increases, the air available for conveying the product decreases. The volumetric flow rate of remaining air may become insufficient to convey product and the pipeline will block. Worn screw flights, valve seats in gate lock valves, and rotary valve blades can all result in greater air leakage. Check these components regularly for wear and replace them when needed. Also check air movers against original manufacturers' specifications.

Keep in mind that a system that conveys one product well may be completely unable to convey another product. Minimum conveying air velocities differ from product to product, and air leakage across feeding devices is also product dependent. If a system has to convey more than one product, this requirement must be considered carefully at the design stage. Fig. 2 plots product flow rate against air flow rate for a range of products.

Long distance charges
Remember that, for any given conveying line pressure drop, the conveying capacity of a pipeline decreases as distance increases. For a change in conveying distance, therefore, there must be a corresponding change of product feed rate into the pipeline.

For a given conveying line pressure drop, the product flow rate is approximately inversely proportional to conveying distance. For a given distance, the product flow rate is approximately proportional to line pressure drop.

If the conveying distance is increased, the product flow rate will have to decrease, so product will be conveyed at a lower phase density. For a product capable of being conveyed in dense phase in a conventional system, a slightly higher conveying line inlet air velocity will be required, in turn, demanding a higher air flow rate.

If the system cannot achieve its rated duty, determine whether the problem is due to product feeding, pipeline or air supply. Check on the conveying line pressure drop. If it is below the air mover's capability, product feed into the pipeline may be insufficient. If the maximum output of the feeder does not meet the conveying capability of the pipeline, however, it will probably be necessary to fit a larger feeder.

Before recommending a larger feeder, be sure that air leakage isn't the real culprit. Check rotary valves in particular, as well as air vents and clearances on all moving parts. Don't forget to check the filtration unit. If it has been incorrectly sized, pressure drop across the filter may be too high. Also check that the filter cloths don't need replacing or cleaning. It may be that an additional or a larger filter is needed. If these modifications don't bring the system to rated output, an air mover with a higher pressure rating or an increase in pipeline bore are indicated, but be sure to consider how this will influence other parts of the system.

Reducing air flow Rate
Improved performance can often be achieved by reducing the quantity of conveying air, particularly if the system is over-rated for volumetric air supply. This could be achieved with a tee and a valve in the conveying air pipework (Fig. 3). In a positive-pressure system, these would be positioned between the air mover and the product feed. In a negative-pressure system, they would be placed between the filtration unit and the air mover. The tee and valve would also allow you to monitor the impact of reduced air flow rate on system performance.

Review routing
Review the pipeline routing and see if the number of bends might be reduced. Blind tees or sharp elbows should be exchanged for short-radius bends. For high-pressure systems with a single-bore pipeline, stepping the pipeline to a larger bore part way along, could also increase throughput.

Remember the potential role that pneumatic equipment wear can play on system performance, particularly when abrasive feeds are involved, and also consider the fact that hygroscopic products can build up within pipe walls. Be proactive, and check on any changes in system performance to avoid problems later on.

Enlarging Piping Tee (opposite to Reducing type from ASME B16.9)?

Hi,

is there any Enlarging (i.e. opposite to Reducing) Tee?
ASME B16.9 provides dimensions for Reducing Tees but I need to insert
a Tee in a location which two sides are of the smaller size than the 3rd side.
is there any such fitting or it has to be specially be made?

Thanks

They are all identified to as Reducing Tee's if any of the ends are different from the two other remaining ends. To identify the tee correctly of the "T" Please give us the dimention of the (horizontal) part of the tee first. Example: 3/4"x1". Then the (perpendicular) 1-1/4" end.So it would 3/4"x1"x1-14". Hope this helps. I will go look for a link for you. Good Luck.
