90 Degree Threaded Elbow
Our forged 90‑degree threaded elbow is a one‑piece hot‑forged pipe fitting with internal NPT taper threads on both ends to change pipeline flow by 90 degrees. Produced strictly following ASME B16.11 and MSS SP‑79 standards, all sizes maintain full nominal dimension without minus tolerance, widely used for power‑plant instrument, hydraulic, fire‑fighting and chemical high‑pressure small‑bore piping systems.
Overview
90‑Degree Threaded Elbow is hot‑forged elbow fitting with female NPT internal threads at both ends. It is applied to adjust pipeline direction by 90° for threaded piping routes.
We adopt hot‑forging forming followed by CNC precision thread‑machining process. Available materials include carbon‑steel A105 and stainless‑steel A182‑F304 / F316L. Internal threads are precisely machined per American NPT standard for leak‑proof performance under high‑pressure conditions. We strictly control wall‑thickness and thread dimension, guarantee zero minus‑tolerance without thin‑wall cutting‑corners. Three pressure classes: Class3000, Class6000, Class9000 are available for different working‑pressure requirements. We also produce 45‑degree threaded elbows upon clients’ requests.
