See how 10 centrifugal casting tube manufacturers compare on alloy grade, dimensional range, and certification before you commit to an RFQ.
The best centrifugal casting tube manufacturers in 2026 are Xinghua Jianda Casting, Global Metal Plastic, Standing Metal Plastic, Zhejiang Tieyong Machinery, Dalian Botong Processed Metals, LAWAI Industrial, Delta Centrifugal, Spuncast, Wirco and MetalTek International. These 10 leading centrifugal casting tube companies span China, Taiwan and the United States.
This list focuses on manufacturers with identifiable centrifugal casting capabilities, rather than simply companies that mention the process in a product listing or directory profile. We’ve reviewed the available factory and process information for each supplier, highlighting where their centrifugal casting capabilities are clearly documented, and where public information is limited.
The 10 best centrifugal casting tube manufacturers each lead on a different capability rather than on size or reputation. Delta Centrifugal is the only ITAR-registered foundry here, LAWAI Industrial the only one casting HP-MOD and 800H, and MetalTek the only one pouring to 180 inches.
The rest split along the same logic. Global Metal Plastic is the only manufacturer holding automotive and medical quality systems together. Spuncast holds enough permanent moulds to skip tooling on a small order, and the four remaining China factories each cover a different end use, from boiler pipe to pump sleeves. If you're looking for other casting manufacturers, please refer to our top die casting companies list, or best investment casting manufacturers.
Diameter is the first column for a reason. It disqualifies faster than anything else, and a foundry that will not publish a range has to confirm your size directly before it can quote.

Xinghua Jianda is the general-industrial entry here, and the one to approach when the alloy is ordinary and the volume is not. Its Jiangsu plant runs to 30,000+ square metres under ISO 9001. It pours alloy steel, cast steel, ferrous metal and stainless steel rather than the high-temperature grades the reformer specialists work in, which matches the industries it serves: automotive, boiler, chemical and HVAC.
Best fit: general centrifugal cast pipe in standard steel grades.

Global Metal Plastic is the only manufacturer here holding automotive and medical quality systems at once, carrying IATF 16949 and ISO 13485 alongside ISO 9000 and ISO 9001. That matters when a cast tube feeds a regulated assembly, because the documentation burden is set by the end product rather than the casting. Its Guangdong facility runs 10 casting methods with CNC machining and fabrication in-house, so casting plus machining stays under one quality system.
Best fit: regulated automotive or medical work, and multi-process parts that would otherwise split across two suppliers.
Source: Global Metal Plastic on Haizol, verified factory profile. No diameter range is published on the profile.
Standing Metal Plastic is the China entry with named furnace-industry experience, serving aerospace and industrial ovens and furnaces specifically. That is worth something, because furnace rollers and radiant tubes fail through creep, carburisation and thermal cycling rather than ordinary wear. A foundry that has supplied the sector already knows what it is being asked for. Standing Metal Plastic holds ISO 9001 and carries nickel alloy among its materials.
Best fit: furnace and industrial-oven tube and roller work sourced from China.
Source: Standing Metal Plastic on Haizol, verified factory profile. No poured-grade list is published on the profile.
Zhejiang Tieyong is the only entry whose named main products are pump and valve components rather than castings in general. For a sleeve or a wear ring that is a better signal than a broad process list, because the tolerances and finishes those parts need are routine work rather than a special request. The Zhejiang plant runs to 30,000+ square metres under ISO 9001, with nickel alloy in its material list.
Best fit: pump and valve sleeves, wear rings and accessory components.
Source: Zhejiang Tieyong Machinery on Haizol, verified factory profile. No diameter range is published on the profile.
Dalian Botong is the only China entry listing titanium alloy, and the only one naming oil well drilling parts among its products. Both point toward the corrosion and pressure duty found upstream in oil and gas rather than general industrial work, which the pressure vessel industry in its served list reinforces. Dalian Botong holds ISO 9001 and also names pump parts and valve parts.
Best fit: oil and gas and pressure-vessel tube components in nickel or stainless alloys.
Source: Dalian Botong Processed Metals on Haizol, verified factory profile. No diameter range is published on the profile.
LAWAI carries the deepest heat-resistant grade list here, and it is the only manufacturer casting HP-MOD and 800H. Its range runs HK, HK40, HF, HT, HU, HH and HP, which is the span a furnace designer works across when service temperature sets the grade. The company has centrifugally cast stainless tube in Taiwan for 25+ years, and describes itself as Taiwan's number one HK40 and JIS SCH22 radiant tube manufacturer.
Best fit: HK40 and JIS SCH22 radiant tubes, plus HP-MOD or 800H work most foundries cannot quote.

Delta Centrifugal is the only ITAR-registered foundry here, which makes it the default rather than an option once a programme carries export-control obligations. It also holds ISO 9001, AS9100 and PED 2014/68/EC, so defence, aerospace and European pressure work run through the same Temple, Texas plant. It casts 200+ grades across stainless, nickel, cobalt and copper alloys, at 3 to 31 inches in diameter and up to 276 inches long.
Best fit: ITAR-controlled, aerospace and defence tube programmes, and PED-scope pressure work.

Spuncast holds more than 1,000 permanent moulds, and that inventory is why a small or repeat order can be economic there when it is not elsewhere. Tooling is the cost that kills a short run. If a mould already exists at your diameter, there is nothing to amortise and no 3 to 6 week wait. Spuncast also casts the smallest published diameter here at 2.5 inches, running up to 44 inches, and keeps heat treating, machining and metallurgical testing in-house.
Best fit: small-diameter, low-volume or repeat orders, and work needing casting through machining under one roof.
Source: spuncast.com.
Wirco is the purest furnace specialist here, building thermal-processing components rather than tube as a general product. Its list runs radiant tubes, furnace rolls and retorts, extending into baskets, trays, muffles and salt pots. That focus pays off when the part is a replacement rather than a new design, because the geometry is already familiar. The company has supplied high-temperature tooling since 1978.
Best fit: radiant tubes, furnace rolls, retorts and heat-treatment replacement parts.
Source: wirco.com.
MetalTek casts far larger than anything else here, to 60 inches outside diameter and 432 inches long horizontally at up to 125,000 pounds, and to 180 inches vertically. Nothing else on this list comes close, so for a large cylinder or shell the shortlist is short. The work runs through its Sandusky International and Wisconsin Centrifugal divisions in nickel grades including 718, 625, GTD222 and Rene77, and reformer tubes are a named application. Wisconsin Centrifugal holds ISO 9001:2015, AS9100D and Nadcap accreditation for heat treatment, laboratory, weld repair and NDT.
Best fit: large-format cylinders, shells and reformer tubes beyond other foundries' size ceilings.

Ask for the published diameter and length range, the permanent mould inventory, and whether the line runs horizontally or vertically. Diameter, moulds and orientation are routine answers for anyone who owns the equipment. A broker reselling castings has to go and ask someone else.
Centrifugal casting cannot be improvised, which is why the test works. Spinning machines are dedicated, moulds are held per diameter, and the two line types suit different geometry. Horizontal lines suit long tubes. Vertical lines suit large-diameter rings and shorter sleeves. Nobody who runs a line is vague about which one they have.
Beyond those three, buyers who source from China regularly rely on the same short checklist:
You can verify a centrifugal casting tube manufacturer on Haizol before sending a drawing, at no cost. Each verified factory profile carries an Own Factory field that separates a manufacturer from a trading company. A production equipment table lists every machine with its capacity, dimensions and year. For centrifugal casting, that table is where the spinning line and its size envelope become visible.
The strongest field is the factory audit report. The report is a dated write-up from Haizol's own facility visit rather than the factory's self-description, listing processing and measuring equipment by name and specification.
Certifications carry a valid-until date and a link to the certificate itself instead of a badge. In-house and outsourced secondary processes are listed separately, so heat treatment and inspection scope is clear before quoting.
Two caveats are worth knowing. The certifications field is not populated on every profile, so read a blank as unknown rather than as absent. And the Industry Type tags show sectors a factory is willing to serve rather than sectors it has proven, so treat the Main Products list as the more reliable signal.
Three failure modes account for most centrifugal casting problems: bore porosity, radial segregation and grade substitution. All three are invisible on a finished part, which is why the evidence has to be specified in the purchase order rather than inspected on arrival.
Inclusions and gas porosity migrate to the bore during spinning. That is normally an advantage, because the bore gets machined away. It becomes a defect when the machining allowance is too small and the contaminated layer stays in the part.
Radial segregation is the second. Under high G-force, alloying elements of different density can separate through the wall, leaving composition that varies from bore to outside diameter. A material test report taken from the wrong location will not show it.
Grade substitution is the third, and the most commercially motivated. HK40 is quoted, something cheaper is poured, and nothing on the delivery note says so.
So put the evidence in the purchase order:
If you need to dive deeper into casting processes, please read our what is casting parts guide.
Reformer tubes go to LAWAI Industrial, MetalTek or Standing Metal Plastic, duplex pressure components to Spuncast, Delta Centrifugal or Dalian Botong, and furnace rollers to Wirco. The application decides fit as much as the alloy family does.
A reformer tube and a furnace roller can both call for HK40, but the foundry built for one does not automatically know the other's service conditions, which is why the same grade appears against different names here.

Yes, and the deciding factor is whether a mould already exists at your diameter. Tooling is what makes a short run expensive, so a foundry holding a large permanent mould inventory can quote a handful of parts that another shop would decline outright.
Ask the question directly: do you already hold a mould at this outside diameter and wall thickness? Spuncast, for example, holds more than 1,000. If the answer is no, expect 3 to 6 weeks of tooling before anything is poured, and price the run accordingly.
Then order a paid pilot batch before the full quantity. It costs a fraction of the order, it proves the alloy and the dimensions on a real part, and it is the cheapest way to find out whether a supplier is what it says it is.
Choosing a centrifugal casting tube manufacturer means confirming process fit, alloy standard, dimensions, certification and post-casting scope, in that order:
Centrifugal casting has no universal minimum diameter. Published ranges across the manufacturers here run from 2.5 inches to 180 inches, and the floor is set per foundry by alloy fluidity, wall thickness, length-to-diameter ratio and the rotational speed the equipment holds. The same foundry may accept a short, thick-walled small tube and reject a long, thin-walled one at the same outside diameter.
Published ranges show how wide the field is. Spuncast casts from 2.5 inches, Delta Centrifugal from 3 to 31 inches at up to 276 inches long, and MetalTek to 60 inches horizontally and 180 inches vertically. Asking for a size outside a published range is asking a foundry to guess.
ITAR registration matters most for defence and nuclear programmes. Nadcap matters most for aerospace special processes such as heat treatment and NDT, and AS9100 for aerospace quality systems generally. ISO 9001 is the baseline and covers none of those on its own.
Those accreditations are also the hardest to find, which is exactly why they filter fast. Across the China factories Haizol has reviewed for centrifugal casting, ISO 9001 is effectively universal, while ITAR, Nadcap and AS9100 are absent entirely. Anything beyond the baseline stays rare enough that IATF 16949 or ISO 13485 narrows a China shortlist immediately. Among the manufacturers here, only Delta Centrifugal carries ITAR registration, and only MetalTek adds Nadcap accreditation alongside AS9100D.
That gap is the practical reason defence and aerospace tube programmes still route to US foundries, and it is worth knowing before an RFQ goes out.
China fits centrifugal casting tube work once the foundry is verified and the alloy and dimensions are locked. A local manufacturer fits programmes where export-control registration, nuclear documentation or aerospace certification is non-negotiable. Chinese capacity concentrates in Jiangsu, Guangdong and Zhejiang, which is where Haizol's reviewed factories are heaviest, while European foundries cluster in Germany and northern Italy.

Centrifugal casting has 2 main types: true centrifugal casting and semi-centrifugal casting. In true centrifugal casting, mould rotation forms the bore from the free metal surface with no central core. In semi-centrifugal casting, rotation assists filling and feeding of a mould containing a core or central geometry, which suits wheels, pulleys, rings and flanges.
Centrifugal casting is cost-effective for symmetrical, hollow, cylindrical parts, because it produces near-net-shape tube with less waste and less machining than cutting from solid bar. It loses that advantage on small runs and irregular shapes, where tooling and setup spread across too few parts.
Centrifugal casting is restricted to symmetrical, largely cylindrical shapes and needs specialised rotating equipment. It also suits complex external geometry less well than investment or sand casting, because its density advantage comes from spinning against a simple mould shape.
Lead time depends on whether a permanent mould already exists for the diameter. Tooling for a new size typically runs 3 to 6 weeks, with production starting 6 to 14 days after tooling approval. Foundries holding large mould inventories can skip tooling for standard sizes.
The right centrifugal casting tube manufacturer proves alloy experience against the grade and standard your part requires, covers your OD and length in its published range, and holds the certification your end industry demands. Company size and quoted price come after all three.
So start with the three questions. Ask for the published range, the mould inventory and the casting orientation. Then match the application to the foundries built for it, confirm the alloy designation and governing standard, and take a paid pilot batch before the full order.
If you want quotes against a specific alloy and diameter, submit an RFQ on Haizol and compare what the verified factories return.
