Grade WPB is a wrought carbon steel made to be welded: its chemistry limits keep weldability high while delivering the strength that process and utility piping needs. When you order a carbon steel elbow, the grade and the schedule together define it — a 6 inch Schedule 80 WPB elbow is a different forging of metal from a 6 inch Schedule 40, even though both measure the same across the bore centreline.
Every carbon elbow order is stated the same way: nominal size, schedule, angle and radius, with the grade — the items that fix the fitting's bore, wall and centre-to-end dimensions before it is formed. The catalogue executions on this page are in WPB; if your specification names a different grade, state it on the enquiry and it will be confirmed for the specific product before order.
| Item | Range / Options |
|---|---|
| Types | 90 deg and 45 deg elbows; long radius 1.5D, short radius 1D — catalogue examples: 90 deg LR in Sch 40, 90 deg SR in XS, 45 deg SR in STD |
| Standards | ASME B16.9 on the 1 inch Sch 40 long radius 90 deg catalogue execution; the standard for each further execution is confirmed per product at enquiry |
| Size range | Confirmed per product at enquiry — catalogue executions include A234 WPB elbows in Sch 40, STD and XS |
| Wall thickness | Ordered to the schedule of the connecting pipe — state the schedule or the exact wall on the enquiry |
| Materials | ASTM A234 WPB in the catalogue executions above; further grades confirmed per product at enquiry |
| Surface | Confirmed per product at enquiry — state any paint or galvanising requirement on the enquiry |
Matching Elbow, Pipe and Weld
A carbon steel elbow earns its place by disappearing into the line: same outside diameter, same wall, compatible chemistry. That is why enquiries work best stated as pipe size plus schedule plus grade — for example NPS 8, Schedule 80, A234 WPB, long radius 90°. If the connecting pipe is specified by exact wall thickness rather than schedule, state the thickness in millimetres on the enquiry and it will be assessed for the specific product before order — the listed executions on this page are the WPB elbows in Sch 40, STD and XS.
Finish and Packing
Surface finish and packing are agreed at quotation. State any paint, galvanising, sorting, marking or case requirements on the enquiry so the finish and the packing arrangement are confirmed for your order before production.
Typical Service
Oil and gas gathering and process lines, steam and condensate, cooling water, compressed air and general plant piping — the broad middle of industrial piping where carbon steel is the economic and mechanical default.
Frequently Asked Questions
Can elbows in other carbon grades be supplied?
The catalogue executions on this page are in A234 WPB. If your specification names a different grade, state it on the enquiry and it will be confirmed for the specific product before order.
What if my line runs at low temperature?
State the design temperature on your enquiry; the grade for the specific product is confirmed against it before order.
Can carbon steel elbows be galvanised?
State the galvanising requirement on your enquiry and it will be confirmed for the specific product at quotation, together with the finish for the execution ordered.
How are carbon steel elbows packed for export?
Packing follows the arrangement agreed at quotation. If a mixed-grade order needs sizes and schedules kept separated and identifiable, state that requirement on the enquiry so it is built into the packing arrangement.
