A tube sheet is the drilled plate that holds a heat exchanger bundle. Every tube is expanded or welded into one of its holes, so the hole pattern, the ligament between holes and the flatness of the face are effectively the whole part. The same forged round plate is also supplied undrilled, bored for a nozzle, or as a plain cover or blanking plate for vessel internals and machinery.
Tube sheets are forged rather than cut from rolled plate when the thickness, the through-thickness properties or the UT requirement demand it. Diameter, thickness, material and drilling scope are taken from the heat exchanger drawing and the TEMA or project notes that go with it. Cladding or weld overlay is quoted where the drawing calls for it.
Hole count, pitch, diameter, ligament width and drilling tolerance decide the machining time, and flatness across a large diameter after drilling is the constraint that catches people out, so state it. Inspection is UT through the plate, a drilling inspection, a dimensional report, PMI where an alloy is involved, MTC 3.1 and third-party witness where the project requires it.
What moves the price is the finished-machining scope: bore, hole pattern, flatness, allowance and surface finish. A plate quoted as a rough forging and the same plate quoted fully machined and drilled are different parts, so say which one you want.

We confirm each step against your drawing or standard before we quote.
Material grade, heat number, certificate basis and substitution limits are checked against the Tube Sheet Forgings drawing or standard before procurement is released.
The forging route is selected around plate diameter or profile, thickness, drilling allowance, flatness risk and tube-hole or plate machining stock.
Heat treatment is planned with attention to thickness, flatness control, material grade and the mechanical-test or impact-test basis required by the project.
Rough machining establishes faces, pilot references and thickness allowance before tube-hole, pipe-hole or drilling operations are committed.
Final machining controls thickness, faces, drilling pattern, tube-hole or pipe-hole layout and flatness before the dimensional report is issued.
Inspection covers thickness, flatness, hole layout where applicable, dimensional report, MTC 3.1 and required NDT or PMI records before release.
Marking, packing and export documents are prepared by PO line item so the Tube Sheet Forgings shipment can clear customs and be identified at site receiving.
List document requirements in the first RFQ; they affect price and schedule.
When the thickness, the through-thickness properties or the UT requirement demand it. Diameter, thickness, material and drilling scope are taken from the heat exchanger drawing and its TEMA or project notes.
Either. We supply drilled tube sheets, machined and drilled tube plates, and undrilled or nozzle-bored round plates; hole count, pitch, diameter, ligament width and drilling tolerance decide the machining time, and drilling is inspected.
Flatness across a large diameter after drilling is the constraint that catches people out, so state it as a drawing requirement.
Yes. Cladding or weld overlay is quoted where the drawing calls for it.
Say which one you want: a plate quoted as a rough forging and the same plate quoted fully machined and drilled are different parts. After weight, the finished-machining scope - bore, hole pattern, flatness, allowance and surface finish - is what moves the price.
