S-7727K139 0.302" ID x 35/64" OD x 5" Long ASME B1.20.1, ASTM A106, ASTM A53, ASTM A733 Thick-Wall Steel Threaded Pipe Nipples and Pipe

Key Features & Benefits at a Glance

• Enhanced Durability & Corrosion Resistance – Black-coated steel construction provides superior protection against rust and wear in demanding industrial environments.
• High-Pressure Performance – Seamless design and Schedule 80 thick-wall structure ensure reliable operation with air, natural gas, oil, steam, and water under high-pressure conditions.
• Leak-Resistant Connections – NPT threaded male ends on both sides deliver secure, tight seals that prevent fluid or gas leakage in critical applications.
• Wide Compatibility – Designed to work with iron and steel fittings (Class 300) and steel flanges (Class 300, 600), offering versatile integration into existing systems.
• Precision Manufacturing – Manufactured to ASME B1.20.1 and ASTM standards (A106, A53, A733) for consistent thread accuracy and dimensional stability.
• Environmental & Safety Compliance – REACH and RoHS 3 certifications guarantee safe, eco-friendly use without hazardous substances.
• Time-Saving Installation – Ready-to-use 5" length with pre-threaded ends reduces assembly time and labor costs in industrial plumbing setups.

Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple is engineered for rigorous industrial service, addressing common challenges like high-pressure fluid handling and corrosive media exposure. The seamless construction eliminates weak points, minimizing the risk of fractures under stress from air, natural gas, oil, steam, or water systems. With NPT threads on both ends, it ensures a uniform, leak-free connection in Class 300 and 600 flange setups, ideal for pipelines requiring frequent maintenance or high torque tolerance. By combining Schedule 80 wall thickness with a protective coating, it extends service life in harsh settings—from chemical plants to power generation—reducing downtime and replacement costs for engineers and procurement teams.
