304 Casting Thread Pipe Fitting NPT Class 150 Screwed for Pipeline
SMLSCO Casting Pipe Fitting Series offers a comprehensive range of
low-pressure threaded pipe fittings to meet general piping needs.
Our product line includes elbows, tees, couplings, and other
fittings designed for directional changes, branching, and straight
connections in pipeline systems.
About Casting Pipe Fittings
Stainless steel casting pipe fittings are economical connection
components designed for low- and medium-pressure piping systems.
Manufactured using precision casting (sol-gel) techniques, these
fittings offer precise dimensions and smooth surface finishes at
competitive prices.
Threaded Connection Advantages
Threaded connections provide easy installation, maintenance, and
disassembly without requiring heat welding. These NPT standard
fittings feature a 1:16 taper that creates an effective mechanical
seal when tightened, making them ideal for industrial and
residential piping systems worldwide.

304/CF8 Material Properties
304 stainless steel (cast grade CF8) offers excellent corrosion
resistance in water, air, and mildly corrosive environments. Its
mechanical properties and ease of processing make it ideal for
manufacturing reliable, cost-effective low-pressure fittings.
Typical Applications
Class 150 cast fittings are essential components in commercial and
residential building piping networks, widely used for connecting,
diverting, and branching drinking water, fire water, circulating
water, and drainage systems. Their threaded connections enable
quick installation of complete low-pressure fluid delivery systems.
FAQ
Q1: What is the difference between 304 and CF8 in cast pipe
fittings?
A1: CF8 is the equivalent grade of 304 stainless steel in the
casting standard (ASTM A351). The chemical composition and
corrosion resistance of the two are essentially the same; CF8 is
the "cast equivalent" of 304.
Q2: Can NPT threaded pipe fittings be mixed with BSPT threads?
A2: No. NPT (American Standard) and BSPT (British Standard) thread
angles and pitches differ. Mixing them can lead to seal failure and
severe leakage. Please be sure to confirm the thread standard for
your system when purchasing.
Q3: What does ISO 4144 primarily specify?
A3: ISO 4144 is a dimensional standard. It primarily defines the
dimensions, tolerances, thread requirements (e.g., NPT), test
pressure, and material marking for Class 150 threaded pipe
fittings.
