Product Introduction: Reducing Tee
A reducing tee is a fitting used to create a smaller 90° branch
from a main pipe. Compared to a "equal-diameter tee + bushing"
combination, using a one-piece reducing tee eliminates one
connection point, thereby reducing potential leaks and lowering
installation costs. This simple, efficient design makes it an ideal
solution for both cost-effectiveness and reliability when diverting
flow from a main line to a smaller branch line.
Introduction to Threaded Cast Fittings
Threaded cast fittings offer an economical, versatile connection
solution for low- and medium-pressure piping systems. Produced
using a precision casting process, they achieve excellent
dimensional accuracy and a smooth surface finish. Their key
advantage is their threaded connection, which eliminates the need
for welding and facilitates subsequent maintenance and
modification. This combination of cost-effectiveness, convenience,
and reliability has made them a standard choice for general
industrial, building water supply and drainage, and civil
engineering applications.
Material Properties
The selection of 316/CF8M stainless steel provides enhanced
corrosion protection for piping systems. When constructing fluid
distribution manifolds, different branch lines may carry different
types and concentrations of media and additives, placing higher
demands on the corrosion resistance of the main fittings. The
inclusion of molybdenum in 316 offers a wider corrosion resistance
range, providing more comprehensive protection and ensuring the
long-term, stable operation of the entire distribution system.
Manufacturing Process
Our cast pipe fittings are produced using a precision casting
(silica sol) process to achieve excellent dimensional accuracy and
surface finish. This process begins with a wax pattern, which is
then coated with multiple layers of refractory material to form a
ceramic shell. The wax is then heated to melt and flow out. Molten
stainless steel is then poured into the hollow shell. After the
molten steel cools and solidifies, the shell is broken to produce a
highly precise pipe blank. This is then machined, tapped, and
finished.
Application
Reducing tees are a core application for constructing fluid
distribution manifolds. In fluid transport systems for water
treatment, agricultural irrigation, HVAC, and general industry,
they are widely used to divert flow from a main pipeline to
multiple smaller devices, instruments, or water points. Reducing
tees enable efficient and economical construction of compact,
well-planned distribution networks to meet diverse flow
distribution needs.
