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

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.
