Key Features & Benefits at a Glance
- Superior corrosion resistance with 304/304L stainless steel construction for extended service life in harsh chemical and moisture-rich environments
- Reliable pressure handling with Schedule 40 wall thickness (0.237") and Class 150 rating for stable performance with air, gas, oil, steam, and water systems
- Leak-resistant connections through precision NPT male threading that ensures tight seals and reduces maintenance downtime
- Versatile industrial compatibility with socket weld and threaded connections for flexible installation in piping networks
- Long-term durability from welded construction that withstands vibration and mechanical stress in continuous operation
- Regulatory peace of mind with RoHS 3 compliance, eliminating hazardous substances for safer workplace use
- Broad application range due to 4" pipe size and straight design, suitable for high-flow industrial transfer systems
Professional Applications & Engineering Value
This 4" Schedule 40 stainless steel threaded pipe nipple delivers critical reliability in demanding fluid and gas handling systems. Its 304/304L stainless steel composition resists oxidation and chemical degradation, preventing premature failure in steam distribution, oil transfer, and water treatment applications. The NPT male thread and socket weld compatibility enable secure, leak-free joints that maintain system integrity under pressure fluctuations. By combining ASTM A312 material standards with 0.237" wall thickness, this adapter solves common pain points like corrosion-induced leaks and thread stripping, ensuring continuous operation in industrial piping networks with minimal maintenance interventions.
Specification Summary & Compliance
Manufactured to ASTM A312 and ASTM A733 material specifications with ASME B1.20.1 threading standards. Dimensions include 4" nominal pipe size, 4.026" ID, 4 1/2" OD, and 3" length with Class 2A thread tolerances. Compliant with RoHS 3 (2015/863/EU) regulations and rated for Class 150 service conditions across air, natural gas, oil, steam, and water applications.
