You want one number for a steel pipe making machine before you commit budget, and every supplier hands back a different range or another question. That is not a sales trick. A tube mill is built around your strip, your sizes and your scope, so a price without those inputs would be a guess we would both regret. We do not publish a price list, and we will not pretend one figure fits every plant.
Here is what we do instead. Our quote form asks for detailed technical requirements, and we design and quote against what you send. This page breaks the investment into the choices that move it, names the figures we cannot state without your data, and shows you how to ask so the number you get back can be compared line by line. Read it before you send an enquiry.
We build every quote from the technical requirements form, not a catalogue. Two buyers can ask for the same model name and need different machines: one runs thin galvanized strip for furniture tube, the other thick carbon steel for structural tube. The rolls, the HF welder setup and the finishing steps all change with those inputs. Size and material decide more of the cost than the badge does.
Our steel tube making machine page lists ERW32 at Φ8–Φ38 mm with 0.3–2 mm wall and ERW630 at Φ325–Φ630 mm with 6–20 mm wall, and says the models are for reference and can be customised to your requirements. A steel pipe making machine quoted from a badge alone would mislead us both. Any figure we have not printed is to be confirmed in writing.
Diameter and wall thickness come first, because they set every roll stand, the squeeze rolls and the saw. A line for ERW254 work at Φ114–Φ254 mm and 3–8 mm wall is a physically different machine from one built for ERW32 at Φ8–Φ38 mm. Ask how far apart your sizes are before you accept a range.
Material changes the welding window. We publish cold and hot rolled carbon steel, low and high resistance carbon steel, galvanized, galvanized aluminium and aluminized steel, stainless steel, aluminium and copper. Coated strip for greenhouse tube needs zinc spraying and dust collecting in scope from the start. We list EN, ASTM, JIS, DIN, GB and API as standards a buyer may specify against; we claim no certification to any of them. Ask which tests your order actually requires.
Two quotes often use the word line differently. Our published integral scope covers equipment, process, layout, foundation, electrical system, cooling water system, air source system, hydraulic system, dust removal system, crane, logistics and maintenance. That is more than a forming mill with a welder bolted on, and our complete steel tube mill line description shows a full scope. Ask where a quote stops.
Then compare the technical process, where missing items hide. Our published sequence runs from coil loading, strip accumulating, forming, H.F. welding, scarfing, seam ironing, cooling, eddy current testing, sizing, ultrasonic testing, cutting off, end finishing and hydrostatic testing to packing and weighing. A quote can quietly drop the accumulator, the ET or UT unit, or the hydro tester. The process is for reference and customisable, so write any deletion into the quote.
Cost items that build a steel pipe making machine quote | |||
Cost item | What moves the number | What we ask you to send | Figure status |
|---|---|---|---|
Forming and sizing section | Tube OD and wall range, number of size changes | Your product mix with diameters | Model ranges published, custom sizes to be confirmed in writing |
HF welding and seam treatment | Material grade and wall thickness | Strip grade and weld seam requirement | Welder power to be confirmed in writing |
Cutting and finishing | Cold saw, facing, threading and packing choices | Which finishing steps belong in scope | Priced per item, to be confirmed in writing |
Line automation and drives | Accumulator, PLC and HMI level | Target speed and staffing plan | Speed by model, to be confirmed in writing |
Utilities and site scope | Foundation, cooling water, air, hydraulic, crane | Site drawing and available utilities | To be confirmed in writing |
Downstream equipment on a steel pipe making machine is where a quote grows quietly, and where you have the most freedom. We publish a long finishing range: cold saw and cold flying saw, pipe end facing, threading, marking, painting, polishing, hydrostatic testing, NDT with ET and UT, and automatic packing. You do not have to buy it all on day one.
A cold flying saw is a cutting choice with its own cost and maintenance habit; decide on it explicitly rather than find it bundled in. Automation is a separate lever: our HF welder runs on a PLC with interlock control, fault diagnosis and an HMI, with variable frequency speed control synchronising individual machines. There is no published price for either option; it is to be confirmed in writing. Decide them before the order, not during manufacturing.
We will not invent your operating cost. We do not publish energy consumption, scrap rates, roller life, efficiency percentages or spare part lead times, and we will not guess them for a plant we have not seen. Those depend on your strip quality, shift pattern and how often you change size. We would rather hand you the inputs than a made-up number we cannot defend.
We can list the consumables: forming rolls, impeders and ferrite cores, induction coils, scarfing inserts, saw blades and zinc wire. We publish international general spare parts as a feature, but the quantity you burn is to be confirmed in writing after your own coils. An automatic pipe packing machine and a strip accumulator also change how many people stand at the line. Those savings are yours to calculate.
The first duplicate is scope creep. A buyer accepts a low quote, then adds end facing, hydrostatic testing and packing one at a time during manufacturing. Each add-on costs more fitted later than specified up front. Ask for the full process list and tick what you want before you sign. Keep that list with the signed order.
The second is the wrong size range. If your mix sits across ERW89 at Φ32–Φ89 mm and 1.5–4.5 mm wall and also much larger pipe, one line may force constant roll changes. We would rather scope two dedicated lines or a quick change roller setup, from W forming, FFX and linear cage or direct forming. The third is utilities: late foundation, cooling water, air and hydraulic requirements mean rework. We offer free technical consultation and drawing review, so use them early.
Give us the tube first, not the steel pipe making machine. List the outside diameters, wall thicknesses, shapes and the standard you sell against. Add the material grades, because galvanized strip and carbon steel do not weld the same way. Tell us the application, whether EMT, scaffolding, water and gas pipe, furniture tube or API line pipe.
Then give us the site: the floor layout, the utilities you have, the target shift pattern and how many size changes you expect per week. Say which finishing steps belong in scope and which you will add later; we design and quote accordingly and will flag assumptions that need to be confirmed in writing. Finally, ask for line items with boundaries and exclusions written down, plus what our pre-shipment performance testing covers.
What to put in the enquiry so quotes line up | |||
Input | Why we need it | If you leave it out | Status |
|---|---|---|---|
Tube diameters and wall thicknesses | Sets roll stands, squeeze rolls and saw size | We cannot size the forming section | Required |
Material grade and coating | Sets the welding window and seam treatment | Scope may miss zinc spraying or dust collecting | Required |
Tube standard and end use | Decides inspection and testing in the line | ET, UT or hydro testing may be excluded | Required, standards are buyer-specified not certified |
Site drawing and utilities | Fixes foundation, cooling water, air and hydraulic tie-ins | Rework after the machine ships | To be confirmed in writing |
Finishing and automation choices | Separates what is in scope from what is added later | Duplicate costs during manufacturing | To be confirmed in writing |
Buying a steel pipe making machine is a specification exercise before a purchasing one. The quote follows your diameters, materials, scope and finishing steps, not a catalogue number. We show where the money goes and where we will not print a figure we cannot defend.
Everything here is grounded in what we publish: the reference models, the customisable process sequence, the standards a buyer may specify against, and the services from drawing review to commissioning and remote fault diagnosis. Prices, delivery windows and capacity figures are to be confirmed in writing, and they belong in your contract rather than an email.
Shijiazhuang FAITH Machinery Co., Ltd. builds your quote from the technical requirements form and shows you the boundaries. Send us your tube list and we will tell you in writing what drives your number and what does not.
Because the machine is built around your strip and sizes, not pulled from stock. Two orders with the same model name can need different rolls, welder settings and finishing equipment. Our quote form asks for detailed technical requirements, and we design and quote against those. Without your tube list, a printed figure would be a guess.
Diameter and wall thickness come first, since they set the roll stands, squeeze rolls and saw. Material grade is next, because coated or stainless strip needs different edge preparation. Then the standard you sell against, which decides how much inspection sits in the line. Tell us those three early and the rest is easier to pin down.
We publish how our solid-state HF welder works, including skin effect, proximity effect, PLC interlock control and HMI monitoring, but not a power rating in kW or a frequency in kHz. Any such figure is to be confirmed in writing against your wall thickness and line speed. We will not invent one to fill a sheet.
Yes, and we would rather you decide that deliberately. Our published process is for reference and can be customised, so we can omit eddy current testing, ultrasonic testing, hydrostatic testing, end facing or automatic packing. Write the deletion into the quote, though. Adding units later costs more than setting the boundary up front.
No. We do not publish energy consumption, scrap percentages, efficiency figures, roller life or spare part lead times, and we will not estimate them. We will give you the consumables list, including rolls, impeders, ferrite cores, scarfing inserts and saw blades. The rest is to be confirmed in writing.
Send the tube list first: outside diameters, wall thicknesses, shapes, material grades and the standard you sell against. Add the application, your floor layout and how often you change size. Say which finishing steps belong in scope. Then ask for line-by-line pricing with exclusions written down, so two quotes can be compared.
