The Industrial-Grade Stainless Steel Coupling Socket 150 is a robust pipe fitting designed to connect steel pipes using a mechanical coupling, providing a reliable, vibration-resistant solution for industrial pipelines. Constructed from 304 or 316 stainless steel, this socket features a grooved end (AWWA C606 compliant) and a reinforced design, ensuring leak-free performance in high-pressure, high-vibration environments.
Grooved Connection Technology:
AWWA C606-compliant grooved end accepts mechanical couplings (e.g., Victaulic®), enabling fast installation with simple wrenches, reducing labor costs by 40% compared to welded systems.
Groove dimensions (depth: 2.4mm ±0.1mm) precision-machined for consistent coupling engagement, suitable for schedule 40/80 pipes.
Heavy-Duty Construction:
304 stainless steel (general use) or 316 stainless steel (corrosive media), with a yield strength of 250 MPa and impact resistance (Charpy V-notch ≥27 J at 20°C).
Rated for working pressures up to 300 PSI (304 stainless steel, schedule 40) and temperatures from -46°C to 650°C, suitable for steam, oil, and gas applications.
Vibration & Corrosion Resistance:
316 stainless steel variant with molybdenum alloying resists pitting in marine and chemical environments, while the grooved design absorbs minor pipe misalignments (up to 3°) to reduce stress.
Smooth internal surface (Ra ≤1.6μm) minimizes turbulence and scale buildup in high-flow systems.
Installation Compliance:
Meet ASME B16.24 and MSS SP-83 standards, with optional galvanic isolation kits for connecting dissimilar metals (e.g., stainless steel to carbon steel).
Ideal for heavy-duty and large-diameter pipeline systems:
Water Distribution: Connecting municipal water mains and fire protection systems (NFPA 20 compliant), with grooved connections enabling quick network expansion.
Industrial Plants: Cooling water circuits and bulk material conveying lines in power plants and refineries, with 316 stainless steel resisting chloride stress corrosion.
Mechanical Systems: Vibration-prone equipment connections (e.g., pumps, generators), with grooved couplings reducing stress on the socket during dynamic loading.
Marine & Offshore: Seawater intake systems and deck piping on ships and platforms, with 316 stainless steel enduring saltwater corrosion and biofouling.
Q: What is the maximum pipe size compatible with this socket?
A: Available in sizes 2" to 48" NPS, with custom sizes up to 72" for large-scale industrial projects.
Q: Can the socket be used with plastic pipes?
A: No, designed for steel pipes; use transition fittings for connecting to plastic (e.g., PVC, PP) pipes.
Q: How to prevent galvanic corrosion with carbon steel pipes?
A: Install a dielectric coupling or wrap the connection with anti-corrosion tape to isolate dissimilar metals.
Q: What is the recommended torque for coupling bolts?
A: Follow the coupling manufacturer's guidelines, typically 50-70 N·m for 2"-12" sockets to ensure uniform sealing pressure.
