Iglele® SS 304 Socket Weld Elbow – Forged Stainless Steel 90° Elbow
High-quality forged stainless steel socket weld elbow for connecting
process piping at 90°. Designed for compact, high-pressure and
high-integrity piping systems where a permanent welded connection
is preferred.
Available in stainless steel grades including SS 304, SS 304L,
SS 316 and SS 316L, subject to product specification and availability.
Socket weld dimensions and pressure classes can be supplied in
accordance with ASME B16.11.
SS Socket Weld Elbow – Product Overview
The Iglele® SS Socket Weld Elbow is a forged stainless
steel pipe fitting used to change the direction of a piping system,
typically through 90°. The pipe enters the socket bore of the fitting
and is joined by a circumferential fillet weld.
Socket weld elbows are particularly useful for small-bore piping,
instrument lines, hydraulic systems, process piping, utility lines,
chemical systems and other applications where a compact welded
connection is required.
Important:
NPS/NB pipe size is a nominal designation and should not be confused
with the actual outside diameter. For example, 1 inch NPS/NB pipe has
a standard outside diameter of approximately 33.4 mm.

The following table helps buyers identify the correct socket weld
fitting size from the nominal pipe size. The pipe OD
is the key dimension for confirming the pipe-to-socket compatibility.

|---|---|---|---|---|
| 1/8″ | DN 6 | 10.3 | 0.405″ | 1/8 NB |
| 1/4″ | DN 8 | 13.7 | 0.540″ | 1/4 NB |
| 3/8″ | DN 10 | 17.1 | 0.675″ | 3/8 NB |
| 1/2″ | DN 15 | 21.3 | 0.840″ | 1/2 NB |

| 3″ | DN 80 | 88.9 | 3.500″ | 3 NB |
| 4″ | DN 100 | 114.3 | 4.500″ | 4 NB |
Note: Pipe OD values are nominal standard dimensions.
Always verify the actual pipe standard, schedule/wall thickness,
fitting class and project specification before ordering.
How to Choose the Correct SS Socket Weld Elbow
Selecting a socket weld elbow should not be based on nominal size alone.
Confirm the following parameters before placing an order.
1. Select Pipe Size
Identify the NPS/NB of the pipe. For example:
- 1/2″ NB → Pipe OD approximately 21.3 mm
- 3/4″ NB → Pipe OD approximately 26.7 mm
- 1″ NB → Pipe OD approximately 33.4 mm
- 1-1/2″ NB → Pipe OD approximately 48.3 mm
- 2″ NB → Pipe OD approximately 60.3 mm
2. Select Material Grade
Specify the required stainless steel grade according to the
fluid, corrosion conditions and design requirements.
- SS 304
- SS 304L
- SS 316
- SS 316L
3. Select Pressure Class
Socket weld fittings under ASME B16.11 are commonly specified
as Class 3000, Class 6000 or Class 9000.
The class number is a fitting classification and must not be
interpreted as a fixed PSI working pressure.
4. Confirm Service Conditions
- Fluid / media
- Design pressure
- Design temperature
- Corrosive environment
- Pipe material
- Pipe schedule / wall thickness
- Applicable piping code
What Is a Socket Weld Elbow?
A socket weld elbow is a forged pipe fitting with a recessed socket
at each end. The outside diameter of the pipe enters the socket,
allowing the pipe to be aligned inside the fitting before a
circumferential fillet weld is made around the socket mouth.
Unlike a butt-weld elbow, the pipe does not require a bevel for the
normal socket-weld connection. This makes socket weld fittings
particularly useful for small-bore piping.
Socket Weld vs Butt Weld:
Socket weld fittings are commonly selected for smaller pipe sizes,
compact installations and high-pressure small-bore piping.
Butt-weld fittings are generally preferred where the piping system
requires a full-penetration butt-weld joint or larger pipe sizes.
SS Socket Weld Elbow Installation Procedure
Socket welding must be carried out by qualified personnel using the
applicable welding procedure specification (WPS), piping code and
project requirements.
Check the fitting and pipeConfirm size, material grade, class, pipe OD and wall thickness.
Inspect the socket for damage, contamination or foreign material.
Cut and prepare the pipeCut the pipe square and remove burrs. Clean the pipe outside
surface and the fitting socket before assembly.
Insert the pipe into the socketInsert the pipe fully into the socket until it reaches the
socket shoulder.
Provide the required expansion gapWhere required by the governing piping code/WPS, withdraw the
pipe approximately 1.5 mm (1/16″) from the socket shoulder
before welding. This accommodates thermal expansion during
welding.
Align and tack weldAlign the elbow correctly with the piping system and tack weld
according to the approved welding procedure.
Complete the fillet weldPerform the circumferential socket weld using the specified
welding process, filler metal, current and qualified WPS.
Inspect the finished weldVisually inspect the weld and perform PT/other NDE where required
by the project specification, piping code or quality plan.
Socket-weld installation requirements are governed by the applicable
piping code and welding procedure. ASME B16.11 defines the fitting;
it does not by itself provide the complete installation welding
procedure. :chatgpt-content-reference{index=”1″}

Socket Weld Class 3000, 6000 & 9000
ASME B16.11 identifies socket-weld fittings by Class 3000,
Class 6000 and Class 9000. These classes are not simply fixed
pressure values in PSI; the allowable pressure-temperature rating
depends on material and applicable rating rules.
| Socket Weld Class | General Pipe Rating Basis | Typical Selection |
|---|---|---|
| Class 3000 | SCH 80 / XS basis as applicable | General high-pressure small-bore service |
| Class 6000 | SCH 160 basis as applicable | Higher pressure service |
| Class 9000 | XXS basis as applicable | Very high-pressure small-bore applications |
Engineering Note:
Do not select a Class 3000/6000/9000 fitting simply from the class
number. Confirm the material, design temperature, design pressure,
pipe schedule and applicable piping code before final selection.

Frequently Asked Questions – SS Socket Weld Elbow
What is a socket weld elbow?
A socket weld elbow is a forged pipe fitting in which the pipe
enters a recessed socket and is joined by a circumferential
fillet weld. A 90° elbow changes the direction of the pipe by
approximately 90 degrees.
What is the OD of 1 inch NB pipe?
1 inch NPS/NB pipe has a standard outside diameter of approximately
33.4 mm (1.315 inch). Pipe wall thickness changes
with schedule, but the nominal OD remains the same for the standard
NPS pipe size.
Is 1 inch NB the same as 33.4 mm OD?
1 inch NB/NPS 1 is a nominal pipe size. Its standard pipe outside
diameter is approximately 33.4 mm. Therefore, a 1 inch socket weld
fitting is selected for the corresponding NPS pipe size, not simply
by treating 1 inch as the actual pipe diameter.
What standards are used for socket weld elbows?
Forged socket-weld elbows are commonly manufactured to
ASME B16.11. Stainless steel forging material may be specified
to ASTM A182, such as F304/F304L or F316/F316L.
What are Class 3000, 6000 and 9000 socket weld fittings?
These are socket-weld fitting class designations under ASME B16.11.
They are not direct fixed PSI ratings. Pressure-temperature
suitability depends on material, temperature, pipe schedule and
the applicable piping code.
What is the recommended socket weld gap?
Where required by the governing piping code and welding procedure,
the pipe is inserted to the socket shoulder and then withdrawn
approximately 1.5 mm (1/16 inch) before welding. The exact
requirement should be controlled by the applicable code and WPS.
Can SS 316L socket weld elbows be used for high pressure?
Yes, SS 316L socket weld fittings can be used in high-pressure
applications when the fitting class, material, pipe schedule,
design pressure, temperature and applicable piping code are
correctly matched.
What information should I provide to buy a socket weld elbow?
Provide nominal pipe size, pipe OD, material grade, socket weld
class, pipe schedule/wall thickness, pressure, temperature,
service media and quantity.
