Professional Applications & Engineering Value

This 1" Schedule 40 stainless steel pipe nipple delivers exceptional engineering value through its 304/304L stainless steel composition, providing optimal resistance to corrosion and oxidation in aggressive media including chemical processing, oil and gas transmission, and high-temperature steam systems. The welded construction combined with NPT threading on one end and socket connect on the other addresses critical installation challenges by enabling secure, leak-resistant joints while maintaining flow efficiency. Engineered to ASTM A312 and ASME B1.20.1 standards, this adapter solves common piping system pain points including thermal expansion stress, pressure fluctuations, and compatibility issues across air, natural gas, oil, steam, and water applications. The 4" length provides optimal spacing flexibility in confined industrial layouts while maintaining structural integrity under Class 150 service conditions.

Specification Summary & Compliance

This precision-engineered pipe nipple features 1" NPT male threading manufactured to ASME B1.20.1 specifications with Class 2A tolerance for reliable sealing performance. The component meets ASTM A312 for seamless and welded stainless steel pipe requirements and ASTM A733 for welded and seamless carbon and austenitic stainless steel pipe nipples. With Schedule 40 wall thickness (0.133") and 1.049" ID/1 5/16" OD dimensions, it ensures precise dimensional compatibility. The product is fully RoHS 3 (2015/863/EU) compliant and suitable for use in regulated industrial environments requiring strict material and environmental compliance standards.
