Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple is engineered to address critical challenges in industrial fluid and gas handling systems. The welded construction and thick-wall Schedule 80 design prevent failures under high-pressure cycles, making it ideal for steam distribution, oil pipelines, and natural gas applications. Its NPT threading ensures secure, standardized connections that minimize leakage risks in 300 and 600 class flange setups. By combining ASTM A53/A733 material standards with a protective coating, it resists corrosion from moisture and chemicals, reducing maintenance downtime in plants, refineries, and HVAC systems. This heavy-duty pipe nipple delivers reliable performance where temperature fluctuations and mechanical stress are common.

Specification Summary & Compliance

This product meets ASME B1.20.1 for NPT thread dimensions and tolerances, ensuring precise fit with compatible fittings. The black-coated steel material conforms to ASTM A53 (specifying seamless/welded steel pipe) and ASTM A733 (covering welded and seamless carbon steel mechanical tubing). It is designed for use with Class 300 and 600 flanges, supporting high-pressure industrial applications. The threaded both ends configuration and 0.147" wall thickness adhere to strict manufacturing controls for durability and pressure rating consistency. Compliant with RoHS and REACH environmental standards, it is suitable for global industrial supply chains.
