Key Features & Benefits at a Glance

Corrosion-resistant black coating extends service life in harsh environments with air, natural gas, oil, steam, and water systems.
Robust welded construction ensures superior structural integrity and leak prevention under high-pressure conditions.
Dual connection versatility with threaded (NPT) and butt weld/socket options allows flexible installation in diverse piping layouts.
Precision NPT threading (ASME B1.20.1 compliant) guarantees secure, leak-tight seals with standard iron and steel fittings.
Heavy-duty Schedule 40 wall thickness provides enhanced durability and pressure handling for Class 125/150 flange applications.
Industry-standard compliance (ASTM A53/A733) assures material quality and dimensional accuracy for reliable performance.
REACH & RoHS 3 environmental compliance meets global regulatory standards for safe industrial use.

Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple solves critical leakage and corrosion challenges in industrial fluid transfer systems. Its welded construction and NPT threading maintain integrity under cyclic pressure stresses, while the butt weld/socket connect design simplifies retrofitting in confined spaces. Engineered for air, natural gas, oil, steam, and water services, it prevents material degradation in high-temperature/pressure environments. The ASTM A53-grade steel and standardized dimensions ensure compatibility with iron and steel flanges, reducing installation errors and downtime in chemical, HVAC, and process piping applications.

Specification Summary & Compliance

Precision-machined to NPT thread standards (ASME B1.20.1) with a 1" pipe size, 2-1/2" length, and Schedule 40 wall thickness (0.133"). Manufactured under ASTM A53 (material) and ASTM A733 (welding) specifications. Fully compliant with REACH (SVHC) and RoHS 3 environmental directives, ensuring safe usage across global industrial markets.
