A complete steel-pipe RFQ contains six non-negotiable specifications: process (ERW/seamless), grade (IS 1239 medium / SA210 Gr A1), outer diameter in mm, wall thickness or schedule, length (SRL/DRL/cut-to-length), and quantity in MT or metres. Add coating, end finish, MTC type, and IBR/TPI requirements as separate lines. Complete RFQs receive same-day responses; incomplete ones require 2-3 back-and-forth messages.

What are the six essential lines in a steel pipe RFQ?

Line 1 — Process: State ERW or seamless. This selects the standards family (IS 1239/3589 for ERW; IS 6286/ASME SA for seamless). Mixing these up delays quotation by a day as the supplier reconfirms intent.

Line 2 — Grade: Explicit grade designation per IS/ASTM/DIN. "IS 1239 medium class", "SA210 Gr A1", "ASTM A53 Gr B". Avoid vague terms like "standard" or "regular" — mills have 12+ grades in stock.

Line 3 — Outer diameter: State in mm (and NB/inches if known). Example: "168.3 mm OD (6" NB)". Include tolerance requirement if tight-fit assembly.

Line 4 — Wall thickness: State in mm or as a schedule (Sch 40, Sch 80). For ERW, specify light/medium/heavy class per IS 1239. For boiler tubes, wall thickness drives pressure rating.

Line 5 — Length: SRL (single random length, 4-7 m), DRL (double random, 7-14 m), or cut-to-length. State tolerance if critical — mills default to ±50 mm on SRL.

Line 6 — Quantity: In metres or MT. Declare delivery instalments if phased. For mill-direct orders, MOQ applies; see our MOQ benchmarks cluster page.

What secondary specs do procurement officers often miss?

End finish determines site weldability: plain end (weld-ready), beveled (for butt welding), or threaded & coupled (T&C). The fitter cannot weld a T&C end without re-cutting — specify up front.

Coating affects delivered price by ₹8-25/kg: black (as-rolled), hot-dip galvanized (HDG per IS 4736), epoxy, or 3LPE for buried service. Specify coating thickness if non-standard.

MTC type (EN 10204): 3.1 is default; 3.2 (TPI countersigned) required for IBR or critical service. Asking post-dispatch is impossible — specify at RFQ.

Documentation bundle: e-way bill, GST invoice, packing list, MTC, TPI report, IBR certificate. Confirm required docs to avoid dispatch delays.

Can I use the prefilled RFQ form instead of writing my own?

Yes — our RFQ form prompts for each of the six lines plus secondary specs. The form validates input and routes directly to the quoting desk. Use the button below to open a prefilled RFQ with "Steel pipe procurement" as the subject.

Frequently asked questions

What is the most common mistake in steel pipe RFQs?
Omitting the process type (ERW vs seamless). This single line determines the standards family, mill selection, and price band. An RFQ without this requires a clarification call, adding 24 hours to response time.
Should I specify the mill name in my RFQ?
Only if you have a contractual or technical requirement. Otherwise, specify the grade and standard; the supplier will propose the most cost-effective mill that meets your spec. Demanding a specific mill without reason may inflate price by 8-15%.
How do I handle phased deliveries in one RFQ?
List the total quantity, then break out instalments with dates and quantities per phase. Example: "Total 100 MT — Phase 1: 40 MT (immediate), Phase 2: 35 MT (Month 2), Phase 3: 25 MT (Month 4)."
Is IBR Form III-C required for all boiler applications?
No — only for boilers operating above the IBR threshold (typically >1 kg/cm² pressure and >22.75 L water capacity). Ask your boiler designer or inspecting authority if IBR applies to your installation.
Can I negotiate payment terms in the RFQ?
State your preference; standard terms are 30-45 day credit on approved accounts. First-time buyers typically pay advance. LC is available for large/export orders but adds 7-14 days to the cycle.
