Large Diameter Aluminum Pipe Manufacturer
Xingyong extrudes large diameter aluminum pipe and tube to order for OEM buyers and importers — big-bore dies, machining and finishing from one factory.
- OD up to 600 mm — the top of our OD 3–600 mm, wall 0.5–50 mm envelope, extruded on a 2,000-ton press.
- Seamless by process — extruded pipe has no weld seam to test, inspect or fail.
- OEM terms that hold — custom dies, samples in 25–35 days, quotes in 24 hours.
What Large Diameter Aluminum Pipe Serves — and Why the Press Decides Who Can Quote
Large diameter aluminum pipe — big-bore round sections from roughly 150 mm up — serves ducting, structural columns, rollers, housings and fluid runs where steel’s weight is the enemy (pipe versus tube naming is half the buyer’s confusion, and we quote both).
Press tonnage is the gatekeeper: big sections need billet force most extruders do not have, which is why the market thins out fast above a few inches — and why distributors quote long leads on anything oversized.
Our 2,000-ton press runs large diameter aluminum tube to 600 mm OD, in schedule pipe sizes or to your print — seamless by process, because extrusion has no weld to begin with.
Jiangsu Xingyong Aluminum Technology Co., Ltd — the factory behind poolpole.com — extrudes the aluminum section, machines ends and features, and anodizes in the same plant.
The round family lives at aluminum round tube with the full range at aluminum tube; structural grades at 6061 aluminum tubing. This page is the big-bore program.
Large Diameter Aluminum Pipe OEM Options — What You Can Spec, Line by Line
Send OD, wall and length first — schedule size or print, either works. One factory owns die, press, temper and finish, so a big-bore program closes in one quote.
| Specification | OEM Options | Confirm Before Sampling |
|---|---|---|
| Size | OD to 600 mm; wall 0.5–50 mm; schedule sizes or custom | OD, wall and tolerance class |
| Alloy & temper | 6063 or 6061; T5/T6 per duty | Structural vs conveyance duty |
| Form | Seamless extruded pipe and tube | Pressure or structural rating expectations |
| Lengths & cutting | Mill lengths or cut-to-length | Length tolerance and end finish |
| Machining | In-house CNC — ends, flanges, ports, keyways | Feature drawing with datums |
| Finish | Mill, anodized, powder coated | Surface class and color codes |
| Plastic parts & assembly (in-house) | Caps and plugs molded to the bore | Cap style and assembly level |
| Packaging | Bundles, crates, export packing | Counts and protection level |
| MOQ & lead time | Per configuration; sampling 25–35 days | Volumes and delivery windows |
Large Diameter Aluminum Pipe Formats We Extrude
Big-bore buyers ask in three vocabularies — schedule pipe, plain inch sizes and seamless spec. One press answers all three.
Schedule 40 Aluminum Pipe
Standard pipe dimensions in extruded aluminum — the schedule chart your fluid and frame drawings already use.
6 Inch Aluminum Pipe
The workhorse mid-bore and up — inch sizes cut, machined and finished to the drawing.
Seamless Aluminum Tubing
Extrusion is seamless by process — no weld line to inspect, polish out or fail under pressure.
Specs reflect big-bore extrusions from Jiangsu Xingyong (ISO 9001 + IATF 16949, since 2010); confirm tolerance class before sampling.
Large Diameter Aluminum Pipe: Extruded vs Rolled-and-Welded vs Steel Pipe
Above a few inches, how the pipe was made is the spec — the honest comparison:
| Point | Extruded big-bore aluminum | Rolled-and-welded aluminum | Steel pipe |
|---|---|---|---|
| Seam | None — seamless by process | Weld line to test and trust | Welded or seamless at cost |
| Roundness | Die-true, meter after meter | Roll springback varies | Good |
| Weight | A third of steel | Same | Heavy — the reason buyers switch |
| Corrosion | Anodized or mill — no coating to chip | Weld zone is the weak point | Coating maintenance forever |
| Where it wins | Programs with a drawing and a volume | One-off giant sizes beyond press reach | Excellent where mass and code demand it |

Frequently Asked Questions
Six answers for the people who sign big-bore drawings — OEM engineers and importers. Hunting one cut length? A metals distributor is faster; this desk is for programs.
Pipe or tube — which am I actually buying?
Pipe is sized by nominal bore and schedule for conveyance; tube by exact OD and wall for structure. We extrude both vocabularies from the same press — send whichever dimension set your drawing uses and the quote speaks it back.
How large can you actually extrude?
OD up to 600 mm with walls from 0.5 to 50 mm — the working envelope of our 2,000-ton press. Beyond that is rolled-and-welded territory, and we say so instead of quoting what we cannot press.
Is extruded pipe really seamless?
Yes — extrusion forms the section from solid billet through a die, so there is no weld line at all. That removes seam testing and seam failure from your qualification list by process, not by promise.
Can you machine flanges and ports?
Yes — end flanges, ports, keyways and mounting features run on the in-house CNC line, so a big-bore part ships machined rather than as raw stock plus a second vendor.
How is large diameter aluminum pipe priced at volume?
By billet weight, section size, temper, machining, finish and volume — plus any custom die, amortized across the program. Factory-direct pricing tracks the aluminum market. Quotes return within 24 hours.
Do you sell cut-to-size single pieces?
No — we are the extrusion layer: dies, mill runs and OEM programs with export packing. For one repair length, a metals distributor serves you faster. If your product is built on a big bore, this page is for you.
