What is Casting Fitting?
SMLSCO stainless steel fittings are produced using precision
casting (silica sol) technology. This process can produce products
with complex shapes, precise dimensions, and high surface
smoothness. Compared to other processes, precision casting is an
ideal choice for producing medium and low pressure threaded pipe
fittings such as Class 150, with excellent product performance and
cost-effectiveness. It is widely used in general industrial,
building, and civil pipeline systems.
Overview of Fitting Connection Types
There are primarily three connection methods for industrial pipe
fittings. Threaded connection, such as this pipe clamp, is suitable
for medium and low-pressure systems, with the advantage of
convenient installation and disassembly. Socket welding is used for
high-pressure, small-diameter pipelines, and is connected through
fillet welds, providing high strength. Butt welding involves
directly welding with the end of the pipeline to form a continuous
and integrated pipeline, with the highest strength and suitable for
various critical and high-demand pipeline systems.
What are the Types of Cast Coupling?
Casting Coupling, also known as pipe sleeve, is used for
straight-line connection between two pipes. It mainly comes in two
forms: Equal Coupling, with the same thread size on both ends, used
for connecting pipes of equal diameter; and Reducing Coupling, with
different thread sizes on both ends, like this product, used for
smoothly transitioning a larger diameter pipe to a smaller one.

SMLSCO Casting Fitting Production Process
SMLSCO cast pipe fittings are produced using precision casting (sol
silica) technology to achieve excellent dimensional accuracy and
surface finish. The process begins with the creation of a wax mold,
which is then coated with multiple layers of refractory material to
form a ceramic shell. The shell is then heated, causing the wax to
melt and flow out. Next, molten stainless steel is poured into the
hollow shell. After the steel cools and solidifies, the shell is
broken away, revealing a high-precision pipe fitting blank. This
blank is then machined, threaded, and other processes to produce
the final product.
Application of 304 Reducing Coupling
Class 150-pound reducers are versatile components in low-pressure
plumbing and fluid conveyance pipelines. They are commonly used to
connect main pipelines with smaller-sized equipment, instruments,
or branch pipelines, achieving a smooth transition in pipe
diameter. In the fields of water treatment, building automation,
and general industrial equipment support, they provide an
economical, reliable, and convenient installation solution for
pipeline diameter changes.
Material and Standards Note
According to the ASTM A351 standard, the official designation for
cast 304 stainless steel is CF8. Although the chemical compositions
of the two are very similar, the industry commonly uses the more
widely recognized "304" for labeling and communication. The cast
pipe fittings supplied by SMLSCO meet the requirements of CF8 in
terms of material properties, providing you with a reliable and
cost-effective solution for general working conditions.
