Professional Applications & Engineering Value

This 1 1/4" Schedule 40 steel threaded pipe nipple is engineered to address critical challenges in industrial fluid and gas handling systems. The black-coated steel material provides an essential protective barrier against moisture and chemical exposure, significantly reducing the risk of corrosion-induced failures in applications involving air, natural gas, oil, steam, and water. Its NPT threaded ends, manufactured to ASME B1.20.1 specifications, ensure a tight, leak-proof seal that maintains system integrity under varying pressure conditions (suitable for Class 125 and 150 fittings). The robust welded construction and standard Schedule 40 wall thickness deliver exceptional burst strength and longevity, making this nipple a reliable component for plant maintenance, pipeline extensions, and machinery connections where downtime must be minimized.

Specification Summary & Compliance

This product conforms to ASME B1.20.1 for NPT thread form and dimensional tolerances, ensuring precise, interchangeable connections. Material and manufacturing comply with ASTM A53 (standard for seamless and welded steel pipe) and ASTM A733 (covering welded and seamless carbon steel pipe nipples). The nipple is designed for use with iron and steel fittings rated for Class 125 and 150 service, confirming its suitability for moderate-pressure industrial systems. While specific RoHS or REACH declarations are not provided in the specifications, the product is manufactured to industry-accepted material and performance standards for reliable, compliant integration.
