Engineering Support
Before anything is quoted, our engineers read your drawing, list what is ambiguous, and send you the questions. We reverse-engineer parts with no drawing, translate specifications into shop-floor Chinese, and check that what you asked for can actually be built the way you drew it.
01 / What we do
A quotation that arrives with no questions attached is a quotation from someone who has not read the drawing.
Roughly a third of the drawings we receive contain something that cannot be built as drawn, or that will be built wrongly because a note means one thing in Denver and another in Hebei. We find those before the price is fixed, not during fabrication.
We read the drawing and send you the questions
Every drawing is reviewed by an engineer who has bought this class of equipment before. Ambiguities, missing views, conflicting notes and impossible tolerances are listed and sent to you in writing before we quote.
We translate the specification, not just the words
Weld symbols, surface finishes, tolerance callouts and material grades are converted into shop-floor instructions in Chinese, and the translation is checked by the same engineer who reviewed the drawing. This is where most quality problems are actually created.
We reverse-engineer what has no drawing
Send the worn part, or photographs with measurements at the points we specify. We scan or measure it, reconstruct the as-new geometry, and mark which surfaces we inferred rather than measured. Nothing is cut until you approve the reconstruction in writing.
We check the design against what the shop can actually do
Plate sizes, rolling capacity, machine envelopes, heat-treatment furnace sizes and crane limits are real constraints. We tell you when a design needs splitting, and what the split does to cost and delivery, before you commit.
We advise on material substitution — and say when not to
Chinese equivalents to ASTM, EN and JIS grades are not always equivalent. Where a substitution is safe we propose it and show the comparison; where it is not, we say so and quote the imported material instead.
We keep the drawings yours
Drawings, patterns and reconstructions produced under your order are yours. They are not shown to other customers and not used for other work. We sign your NDA before you send anything.
02 / The cost of skipping it
What it costs when nobody reads the drawing first.
None of these are hypothetical. They are the reasons customers came to us after buying direct, and every one of them was cheaper to prevent than to correct.
| What goes wrong | How it shows up | What it costs you |
|---|---|---|
| A note is read the way it was written, not the way it was meant | “Machine all over” applied to a face that only needed a spot face, or a general tolerance applied to a critical fit. | Rework or scrap on a finished part, and a delivery date that moves by weeks with no warning. |
| A material grade is substituted quietly | A Chinese equivalent is used because the specified grade was hard to source, and the certificate says the equivalent. | You discover it during commissioning, or you never discover it at all — which is worse. |
| The design cannot be built as drawn | Plate width, rolling diameter, furnace size or crane capacity does not exist at the shop that took the order. | A split introduced by the fabricator without telling you, in a place your engineer would never have put it. |
| A reverse-engineered part is “close” | Nobody approved what the as-new geometry should be, so the fabricator guessed from a worn sample. | A part that fits but wears out fast, or does not fit and cannot be returned economically. |
| Nobody asked what the equipment is for | A vessel is built to the drawing while the duty on the data sheet contradicts it. | Equipment that meets its drawing and fails its job. The drawing wins any argument, which is why the argument has to happen first. |
Every row here is prevented by the same thing: an engineer reading the documents properly, in both languages, before money is committed. That is what this service is.
03 / The deliverable
What you actually receive.
Engineering support is not a line item we add to a price. It is a set of documents you get, before and during the order, whether or not you buy the equipment from us.
| Drawing review report | A written list of ambiguities, conflicts and buildability issues, raised before the quotation is issued |
|---|---|
| Reverse-engineering package | 3D scan or measured dimensional reconstruction, with inferred surfaces identified, issued for your written approval |
| Material comparison | Side-by-side chemistry and mechanical comparison where a substitution is proposed, with a recommendation and a reason |
| Fabrication plan comment | Where a design has to be split, sectioned or sequenced differently, with the effect on cost and delivery stated |
| Translated shop instructions | The specification as the shop floor will actually read it, checked by the reviewing engineer |
| Approval record | Written confirmation of every reconstruction, substitution and design change you accepted, retained in the data book |
| Confidentiality | NDA signed before receipt; drawings and patterns remain yours and are not used for other customers |
04 / Questions
Engineering support — common questions
Do you charge separately for this?
On equipment orders it is part of how we work and is included. As a standalone service — reviewing drawings for an order you are placing yourself — it is quoted as a fixed fee per drawing package. See Inspection & Expediting, where drawing and ITP review is module B.
Are you a design house?
No, and we will not pretend to be. We do not stamp designs or take design liability. We review, translate, reverse-engineer and advise on buildability. Where a design needs a professional engineer, that stays with your engineer or your EPC.
What do you need to reverse-engineer a part?
Ideally the part itself. Failing that, photographs with a scale in frame and measurements at the points we nominate — we will tell you exactly which ones. The output is a dimensional reconstruction you approve before anything is cut.
Can you work from a scanned or hand-drawn sketch?
Yes. A large share of what we build starts as a sketch or a marked-up photograph. We turn it into a dimensioned drawing, send it back for approval, and build only to the approved version.
Will you tell us if our own specification is wrong?
Yes. If your specification conflicts with the duty you have described, we raise it before quoting. We would rather lose the order than build to a specification we believe will fail.
Send the drawing. We will send the questions.
Upload a drawing, a sketch or a photograph of the part. You will get a written review before you get a price.
