D. SWEEP ELBOWS - BLIND TEE

With pneumatic conveying, abrasion normally occurs in the pipe
bends and in the subsequent straight sections where the conveyed
material is subject to a high degree of turbulence.
Ways to minimize Abrasion:
•Abrasive Inlets
•Convey lines should be of a abrasion resistant material such as Abr-
Flex hose.
•Some applications can utilize long radius elbows where others
require either special “tee” pockets (right angle) to protect against
wear.

BLIND-TEE ELBOW
The blind-tee elbow creates a product-to-product primary impact
zone and eliminates the high-impact contact of incoming particles
against the elbow wall. This reduces wear as well as degradation of
fragile and heat-sensitive products.
ADVANTAGES. The blind-tee elbow can be made of different
materials and with different angles. Its compact design requires less
space than standard elbows, making it easy to retrofit. Wear and
product degradation are low due to its product-to-product primary
impact zone. It is the lowest-cost specialty elbow.
DISADVANTAGES. The blind-tee has extremely high pressure
losses. Dead zones and product pockets may lead to product cross-
contamination. The secondary impact zone can raise wear and
degradation issues.
Recommended applications are short, dilute- or dense- phase
systems with dedicated product lines where product pockets are not
critical. It can handle fluidizable powders that are abrasive, head-
sensitive or fragile.
