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.
