Key Features & Benefits at a Glance
- Dual-thread versatility with right-hand and left-hand NPT threads enables flexible installation and connection in complex piping systems.
- Robust welded steel construction ensures high structural integrity and leak-resistant performance under demanding industrial conditions.
- Black-coated steel surface provides enhanced corrosion resistance, extending service life in humid or chemically aggressive environments.
- Broad media compatibility safely handles air, natural gas, oil, steam, and water, reducing inventory needs for multiple fluid types.
- Precision threading per ASME B1.20.1 guarantees secure, pressure-tight seals with Class 125 and 150 iron/steel fittings.
- Schedule 40 wall thickness (0.145") delivers optimal strength-to-weight ratio for high-pressure applications without unnecessary bulk.
- Full regulatory compliance with REACH and RoHS 3 ensures environmental safety and global market acceptance.
Professional Applications & Engineering Value
This heavy-duty steel pipe nipple solves critical challenges in industrial fluid and gas transfer systems. Its dual right-hand and left-hand NPT threads allow engineers to create secure connections in confined spaces where standard single-direction threading is impractical. The black-coated steel construction resists corrosion from steam, water, and chemical exposure, while the welded design maintains integrity under vibration and pressure cycling. Meeting ASME B1.20.1, ASTM A53, and ASTM A733 specifications, this nipple delivers reliable performance in petroleum, manufacturing, and utility applications where Class 125 and 150 fittings are standard. The 6" length and 1 1/2" Schedule 40 dimensions make it ideal for connecting valves, pumps, and regulators in high-pressure piping networks.
Specification Summary & Compliance
This pipe nipple features precision NPT threads on both ends manufactured to ASME B1.20.1 standards for reliable sealing. The Schedule 40 construction with 1.61" ID and 1 29/32" OD maintains dimensional accuracy per ASTM A53 and ASTM A733 specifications. Product complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives, ensuring safe use across global industrial markets.
