3/4 inch x 3 inch Stainless Steel Nipple

3/4 Inch x 3 Inch Stainless Steel Nipple – Schedule 40, Threaded Ends

The 3/4 inch x 3 inch stainless steel nipple is a straight pipe fitting designed for joining two threaded components within pressurized systems. Manufactured from corrosion-resistant stainless steel, this Schedule 40 pipe nipple supports mechanical and plumbing applications that require high strength, chemical resistance, and dimensional consistency.

Fabrication Standards and Material Properties

This nipple is constructed from Type 304 or 316 stainless steel (based on specification), offering excellent resistance to oxidizing agents, chlorinated water, and general atmospheric conditions. Precision-machined NPT threads ensure compatibility with ANSI/ASME B1.20.1 tapered fittings. Notable features include:

• ✅ ASTM A312 or A733 Compliance – Manufactured to meet or exceed industry dimensional and material specifications.
• ✅ Corrosion Resistance – Suitable for potable water, HVAC, compressed air, and chemical handling applications.
• ✅ Threaded Connections – Both ends feature male NPT threads for ease of integration with valves, couplings, and other threaded fittings.
• ✅ Wall Thickness – Schedule 40 wall for standard pressure and flow applications in commercial and industrial systems.

Technical Specifications

• Nominal Size: 3/4 inch
• Length: 3 inches (threaded end-to-end)
• Material: 304 or 316 Stainless Steel (verify per order)
• Wall Specification: Schedule 40
• Connection Type: Male NPT x Male NPT
• Pressure Rating: Dependent on system design, temperature, and media; consult piping standards for specifics

Installation Guidelines

Apply an approved thread sealant or PTFE tape to male threads prior to installation. Over-tightening may damage threads or mating components. Proper torque and alignment are essential to prevent mechanical stress or potential leakage at the joint. Suitable for use in stainless steel and dissimilar metal assemblies when galvanic corrosion precautions are taken.

Typical Applications

Used in mechanical rooms, process piping, water filtration systems, and equipment connections in food processing, pharmaceutical, and commercial plumbing installations. Common for use in potable water systems, closed-loop hydronic systems, and industrial fluid handling lines requiring high corrosion resistance and mechanical durability.

Material Performance Note

Stainless steel nipples outperform carbon steel and galvanized options in environments exposed to water, steam, and corrosive agents. Type 316 is preferred for marine or chemical applications due to its molybdenum content, which enhances resistance to chlorides and acids.

Manufacturing and Quality Control

Threaded pipe nipples are manufactured via precision cutting and threading processes and undergo inspection for concentricity, thread depth, and length accuracy. Welded and seamless options may be available based on specification. Each fitting is traceable to batch-level quality documentation per standard industry requirements.
