Elbows, tees, reducers, caps, stub ends, forged fittings and branch outlets in stainless steel,
duplex, carbon steel, alloy steel and nickel alloys — with the matching grades, dimensions and
tolerances you need to specify them.
Product Overview
Fittings to Match Every Pipe We Supply
We supply butt weld fittings, forged socket weld and threaded fittings, and branch
outlets in stainless steel, duplex, super duplex, carbon steel and alloy steel — and in
nickel alloys, titanium and copper-nickel for the lines that need them.
Fittings are supplied in the same grade and schedule as the pipe they join, so the whole line
comes with one set of documents. Every fitting is stamped with its grade, size and heat number and
supplied with a mill test certificate to EN 10204 Type 3.1 or 3.2. When your project needs
independent verification, inspection by your nominated agency is carried out before dispatch.
The end connection decides the size range, the pressure the joint can take and how it is made on site. Most lines use butt weld fittings, with socket weld and threaded fittings on small bore.
Butt weld
Bevelled ends welded right through the wall. The joint is as strong as the pipe, with a smooth bore. Standard for NPS 2 and above, and available from NPS 1/2.
Standards: ASME B16.9 · MSS SP-43 · bevels to B16.25
Socket weld
The pipe slides into a socket and is fillet welded. Easy to align, with no bevelling. A small gap is left at the bottom of the socket to allow for weld shrinkage.
Standards: ASME B16.11 · NPS 1/8 to 4 · Class 3000, 6000, 9000
Threaded
Screwed together on tapered threads, with no welding. Quick to install and take apart, for small-bore utility, instrument and low-pressure lines.
Standards: ASME B16.11 · NPT to B1.20.1 or BSP · Class 2000, 3000, 6000
Fitting Types
Every Shape the Line Needs
Fittings change direction, split or combine flow, change size and close the line. These are the shapes we supply, grouped by how they connect.
Butt weld fittings
90° Elbow
LR · SR · B16.9
Turns the line through a right angle. Long radius is the default.
45° Elbow

3D & 5D Bend
Induction bent
Bent from pipe on a large radius, for pigging lines.
Elbows
Long Radius, Short Radius or Bend?
An elbow is sized by the pipe it joins and by how tightly it turns. The centre-to-end
dimension, A, is what your piping designer uses to lay out the line.
Long radius (LR)
Centre-line radius of 1.5 × NPS. The default for process piping: gentler flow, lower pressure drop and less wear.
Short radius (SR)
Centre-line radius of 1.0 × NPS, for tight spaces. More pressure drop than LR.
3D & 5D bends
Radius of 3 or 5 times the pipe size, bent from pipe. Lets pigs and scrapers pass.
Angles
90° and 45° elbows and 180° returns as standard; other angles to order.
A, centre to end: from the point where the two centre lines meet to the face of either end.
R, bend radius: the radius of the centre line. For a 90° elbow, A equals R.
Example: a 4" LR elbow has A = 152 mm; a 4" SR elbow has A = 102 mm.
Materials & Grades
Fitting, Forging and Pipe, Matched
Each material has one specification for butt weld fittings, one for forged fittings and one for pipe. Choose a family to see the grades that belong together.
Stainless Steel Fittings
Wrought fittings to ASTM A403 match A312 pipe grade for grade. Light-wall fittings for Sch 5S and 10S pipe are made to MSS SP-43 and marked CR instead of WP.

Values are shown for reference and follow the specifications named in the table. Limits are revised from time to time, so the edition of the specification on your order, and the mill test certificate supplied with the material, always govern. Butt weld alloy grades A234 WP5 to WP91 follow the A335 pipe chemistry on the Pipes & Tubes page.
Mechanical Properties
Strength and Size, Compared
A fitting must be at least as strong as the pipe it joins, so its grade follows the pipe. The second chart shows how the length of a long radius elbow grows with pipe size.

Weld bevel · ASME B16.25
For walls up to 22 mm. Thicker walls take a compound bevel, also to ASME B16.25. Other bevels are cut to your welding procedure.
Surface
Stainless fittings pickled or sand-blasted. Carbon steel fittings varnished or oiled against rust, as ordered.
Marking & packing
Each fitting stamped or stencilled with grade, size, schedule and heat number. Ends protected with caps, packed in wooden cases for export.
Selection
Which Fitting for Which Job?
A starting point for choosing the type of fitting. The material follows the pipe; the fitting type follows the size, the service and how the line is built.
Situation
Typical choice
Why
Process lines, NPS 2 and above
Butt weld · B16.9
Full-strength welded joint with a smooth, crevice-free bore.
Small-bore lines at high pressure
Socket weld · Class 3000 / 6000
Easy fit-up with no bevelling; strong fillet-welded joint.
Utility, instrument & low-pressure lines
Threaded · Class 2000 / 3000
No welding. Not suited to cyclic, toxic or flammable service.
Thin-wall stainless, Sch 5S & 10S
MSS SP-43 · CR grades
Light-wall fittings made to match light-wall pipe.
Normal change of direction
90° / 45° LR elbow
Gentle turn with low pressure drop and wear.
Tight spaces
90° SR elbow
Shorter centre-to-end, at the cost of more pressure drop.
Pigging & slurry lines
3D / 5D bend
Large radius lets pigs pass and reduces erosion.
Pump suction reduction
Eccentric reducer, flat side up
No air pocket can form at the top of the line.
Small branch on a large header
Weldolet · sockolet · threadolet
Cheaper and lighter than a reducing tee.
Flanged joints in costly alloy
Stub end + lap joint flange
Only the stub end is alloy; the flange can be carbon steel.
Joints that are opened often
Union
Can be taken apart without cutting the pipe.

Testing & Documents
Tested, Traceable & Documented
Every fitting is traceable to its heat number and leaves with its mill test certificate. These tests are arranged when your order calls for them.

What is the difference between long radius and short radius elbows?
The bend radius. A long radius (LR) elbow bends on a centre-line radius of 1.5 times the nominal pipe size, a short radius (SR) elbow on 1.0 times. LR elbows are the default in process piping because the flow turns more gently, with less pressure drop and wear. SR elbows are used where space is tight. See the elbow drawing.
What do S, W, WX and WU mean in a fitting grade?
They describe how the fitting was made. S is seamless. W is welded. WX is welded with all welds radiographed. WU is welded with all welds ultrasonically tested. For example, A403 WP316L-S is a seamless 316L stainless fitting and A403 WP316L-WX is a welded one with fully radiographed welds. See reading a marking.
Should the fitting schedule match the pipe?
Yes. A butt weld fitting is ordered in the same nominal size and schedule as the pipe it is welded to, so the walls line up at the weld. The fitting grade should also match the pipe grade, for example A403 WP316L with A312 TP316L pipe.
Should I choose Class 3000 or Class 6000 socket weld fittings?
Match the class to the pipe schedule. Under ASME B16.11, Class 3000 socket weld fittings go with Schedule 80 pipe, Class 6000 with Schedule 160 and Class 9000 with XXS. For threaded fittings, Class 2000 goes with Schedule 80, Class 3000 with Schedule 160 and Class 6000 with XXS.
When should I use an eccentric reducer?
An eccentric reducer keeps one side of the pipe straight. At a pump suction it is installed flat side up, so no air pocket can collect at the top of the line. In pipe racks it is often installed flat side down so the line drains, or to keep the bottom of pipe at one level on its supports.
What documents are supplied with pipe fittings?
Every lot is supplied with a mill test certificate to EN 10204 Type 3.1 or 3.2, traceable to the heat number marked on each fitting, along with any additional test reports ordered, such as radiography, PMI or intergranular corrosion tests. When third-party inspection is called for, the agency's inspection release note is included. More on our quality & inspection page.
