Professional Applications & Engineering Value

This heavy-duty Schedule 80 steel threaded pipe nipple addresses critical industrial challenges where corrosion resistance and pressure integrity are paramount. The black-coated steel surface treatment significantly reduces oxidation in humid or chemical-exposed environments, while the thick-wall construction (0.179") prevents deformation under high-pressure conditions common in natural gas distribution, steam systems, and industrial oil pipelines. The precision NPT threading conforming to ASME B1.20.1 ensures seamless integration with Class 300 and 600 flanges, eliminating leakage points in critical connections. Engineered for welded construction durability, this straight pipe nipple maintains structural stability in vibrating systems, making it ideal for industrial plant maintenance and process piping upgrades where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to exacting thread standards ASME B1.20.1 with NPT thread form, ensuring precise engagement with compatible fittings. The 2-1/2" length maintains dimensional accuracy per industrial requirements, while material specifications meet ASTM A53 and ASTM A733 standards for consistent mechanical properties. Compatible with Class 300 iron/steel fittings and Class 300/600 steel flanges, this product demonstrates full compliance with industrial pressure rating requirements. The manufacturing process adheres to standardized welded construction protocols, guaranteeing uniform wall thickness (0.179") and internal diameter (0.957") throughout the Schedule 80 pipe nipple structure.
