Professional Applications & Engineering Value

This fully threaded pipe nipple solves critical sealing and pressure containment challenges in industrial fluid systems. The black-coated steel surface resists oxidation from steam and chemical exposure, while the welded construction maintains integrity under cyclic pressure stresses. NPT threads cut to ASME B1.20.1 specifications create zero-leak junctions with iron/steel flanges, eliminating downtime in oil, gas, and steam applications. Its Schedule 40 wall thickness (0.145") withstands erosion in high-flow environments, making it ideal for connecting pumps, compressors, and processing equipment where reliability is paramount.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 thread standards with ASTM A53 material certification and ASTM A733 commercial standard compliance. Dimensions include 1 1/2" NPT pipe size, 1.61" ID, and 1 29/32" OD with Class 2A thread tolerances. Suitable for use with Class 125 and 150 iron/steel fittings. RoHS and REACH compliant materials ensure environmental responsibility.
