Nine items that decide whether a fabricator can price your spools in days instead of weeks.
Most delays in a spool quotation are not about the price. They are about missing information, and the questions that follow. These are the nine items we ask for first.
1. Isometric drawings, or a line list with an MTO. Isometrics let the fabricator count welds and dia-inch directly, which is how spool work is really priced.
2. The piping class or material specification for every line: pipe, fittings, flanges, wall thickness and rating. Carbon, low temperature, stainless and duplex are priced very differently.
3. The design code, for example ASME B31.3, B31.1 or EN 13480, and any client specification that overrides it.
4. NDE scope: the percentage of radiography or ultrasonic testing, PT or MT, and PMI if required.
5. Heat treatment and testing: PWHT, hardness testing, hydrotest or pneumatic test, and who supplies test blinds.
6. Surface treatment: blasting standard, paint system and dry film thickness, or pickling and passivation for stainless.
7. Certification: material certificates (EN 10204 3.1 or 3.2), and whether PED, CE or a third party inspector applies.
8. Quantities, required delivery date and delivery term, for example FOB Tianjin.
9. The date you need the offer, so the shop can plan the takeoff.
With these nine items in hand we can usually return a priced offer within a few working days. Send what you have; we will list anything missing in one message rather than in ten.
