• Welded construction durability provides enhanced structural integrity for long-term reliability in industrial applications.
• Broad compatibility with 125 and 150 class galvanized iron and steel fittings, simplifying installation across various systems.
• Standard Schedule 40 wall thickness offers optimal strength-to-weight ratio for handling moderate to high pressure fluids and gases.
• Rigorous quality assurance through compliance with ASME, ASTM A53, and ASTM A733 standards guarantees dimensional accuracy and material consistency.
• Versatile male threaded design enables quick connections in plumbing, HVAC, and industrial piping networks without additional adapters.

Professional Applications & Engineering Value

This galvanized steel threaded pipe nipple addresses critical industrial challenges where corrosion and pressure integrity are paramount. The zinc-coated surface actively resists oxidation in moist or chemical-exposed environments, significantly extending service life in air, natural gas, oil, steam, and water systems. Its welded construction and NPT threads maintain seal integrity under thermal cycling and vibration, preventing costly leaks in class 125 and 150 applications. Engineers specify this Schedule 40 pipe connector for its reliable performance in industrial plants, commercial plumbing, and process piping where ASTM A53/A733 compliance ensures consistent wall thickness and thread engagement for pressure-containing services.

Specification Summary & Compliance

This 1" Schedule 40 pipe nipple features NPT threads per ASME B1.20.1 with standard Class 2A tolerances for proper gaging and fit. The galvanized steel construction meets ASTM A53 (standard specification for pipe) and ASTM A733 (welded and seamless carbon steel mechanical tubing) requirements. Dimensions include 2" length, 1.049" ID, 1-5/16" OD, and 0.133" wall thickness. Suitable for use with galvanized iron and steel fittings in class 125 and 150 applications, this component complies with industry standards for mechanical properties and dimensional consistency in pressurized systems.
