Construction Details
SCI Heavy Pattern 150# 90° Elbows are manufactured from cast stainless steel. SCI identifies the 304 stainless steel castings as ASTM A351 ACI Grade CF8 and the 316 stainless steel castings as ASTM A351 ACI Grade CF8M.
The fitting uses female threaded openings at a 90-degree angle, allowing two compatible male NPT piping components to be connected while changing the direction of the piping run.
SCI specifies that the NPT threads conform to ASME B1.20.1. :contentReference[oaicite:1]{index=1}
90° Elbow Configuration
90-Degree Direction Change
The elbow redirects the piping run by 90 degrees, making it useful where the system needs to turn around equipment, structural components, or changes in piping layout.
Female Threaded Connections
Both ends use female NPT threads for connection to compatible male-threaded pipe, nipples, fittings, or equipment connections.
304 & 316 Stainless Steel Options
304 Stainless Steel
SCI Figure S3114E identifies the 304 stainless steel 90° elbow. SCI specifies ASTM A351 ACI Grade CF8 for its 304 stainless castings.
316 Stainless Steel
SCI Figure S3116E identifies the 316 stainless steel 90° elbow. SCI specifies ASTM A351 ACI Grade CF8M for its 316 stainless castings.
NPT Threaded Connections
The fitting uses female NPT threaded connections on both ends. SCI specifies NPT threads conforming to ASME B1.20.1.
Confirm the nominal pipe size and male NPT thread requirements of the mating piping components before ordering or installation.
Heavy Pattern Construction
This fitting is part of SCI's Heavy Pattern 150# Stainless Fittings family. The heavy-pattern configuration provides the dimensional construction documented by SCI for its cast stainless threaded fitting line.
The manufacturer's catalog provides fitting dimensions, part numbers, packing information, and published weights for the 90° elbow family. :contentReference[oaicite:2]{index=2}
Typical Applications
Industrial & Process Piping

Installation & Selection Considerations
- Confirm the required nominal pipe size and female NPT x female NPT connection before ordering.
- Select the appropriate 304 or 316 stainless steel configuration for the intended piping system and process media.
- Verify compatibility of the fitting material with the operating pressure, temperature, and service conditions.
- Use appropriate thread-sealing practices and avoid cross-threading or excessive installation torque.
- Fully isolate and depressurize the piping system before installing, removing, or servicing threaded fittings.
