Reducing Coupling 3/4" 304 Threaded BSPT Class 150 Casting Fitting

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.
