Construction Details
SCI Heavy Pattern Class 150 45° elbows are manufactured from cast stainless steel. The 304 stainless steel version uses ASTM A351 Grade CF8 material, while the 316 stainless steel version uses ASTM A351 Grade CF8M.
The fitting incorporates female NPT connections at both ends for joining compatible male-threaded pipe, nipples, valves, and other threaded components.
The 45-degree elbow configuration provides a directional change that is less abrupt than a 90-degree elbow, making it useful where piping layout requires an angled transition.

Frequently Asked Questions
What is a 150# stainless steel 45° elbow used for?
It provides a 45-degree change in direction between compatible threaded piping components.
What figure numbers identify this 45° elbow?
SCI identifies the Heavy Pattern 45° Elbow as FIG S3114F for 304 stainless steel and FIG S3116F for 316 stainless steel.
What stainless steel grades are available?
The elbow is available in 304 stainless steel ASTM A351 CF8 and 316 stainless steel ASTM A351 CF8M configurations.
What connections does this elbow use?
The fitting uses female NPT threaded connections at both ends.
What standard applies to the NPT threads?
The NPT threads conform to ASME B1.20.1.
How does a 45° elbow differ from a 90° elbow?
A 45° elbow creates a more gradual directional change, while a 90° elbow changes piping direction by a full right angle.
Is 150# the same as a 150 PSI working pressure?
No. Class 150 identifies the fitting pressure class and should not be interpreted as a universal 150 PSI working-pressure rating.
What should I confirm before ordering?
Confirm pipe size, stainless steel grade, NPT requirements, process media, and system operating conditions.
Important Ordering & Installation Notes
- Confirm the required pipe size.
- Select 304 or 316 stainless steel.
- Verify service compatibility.
- Use suitable thread sealant.
- Avoid excessive thread torque.
