What Is ASTM A106 Grade B Seamless Pipe?

ASTM A106 Grade B is the most widely specified seamless carbon steel pipe standard in the world for high-temperature, high-pressure service. Produced under ASTM International's A106 specification — and its ASME pressure-vessel equivalent, ASME SA106 — Grade B is the workhorse of refineries, power plants, chemical processing units, and major infrastructure projects globally.

Manufactured entirely without a weld seam, seamless pipes offer superior mechanical integrity, making them the default choice wherever pressure surges, thermal cycling, or corrosive media are present. The Grade B designation signals a minimum tensile strength of 415 MPa (60,000 psi) and a yield strength of 240 MPa (35,000 psi), providing a generous safety margin for demanding service conditions.

ℹ️ Buyer's Note:- ASTM A106 Gr B vs ASTM A53 Gr B: Both are carbon steel seamless pipe standards, but A106 is mandated specifically for high-temperature service (up to 482°C / 900°F), whereas A53 covers a broader application range including lower-temperature use. For refineries, boiler piping, and steam lines, always specify A106 Grade B.

In India, A106 Grade B seamless pipes are manufactured at integrated steel mills and precision pipe mills that comply with BIS, ISO 9001:2015, and international third-party inspection standards. Indian-make A106 Grade B pipes have established a strong reputation in domestic and export markets for consistent chemistry, dimensional accuracy, and competitive pricing compared with equivalent Japanese, Korean, or European mill supply.

✅ Price Trend — May 2026 - Prices in the 50 NB to 150 NB range (all schedules) remain stable at ₹75/kg, reflecting healthy domestic mill supply and steady HRC input costs. Small bore sizes (15–40 NB) attract a premium due to higher per-kg fabrication cost. Large bore sizes (400–500 NB) trend higher at ₹90–₹105/kg reflecting reduced domestic production and higher raw material consumption per unit length.

Why Do Seamless Pipe Prices Vary by Schedule & Size?

A common question from first-time buyers is why a 300 NB Sch 20 pipe costs ₹88/kg while a 300 NB Sch 40 or 80 costs ₹81/kg. The inverse relationship — where heavier wall (higher schedule) is sometimes cheaper per kg — can be counterintuitive. Here's why:

1. Mill Production Volume & Efficiency

Sch 40 and Sch 80 pipes in mid-range bore sizes (50 NB to 300 NB) are produced in the highest volumes at Indian seamless pipe mills. Economies of scale keep per-kg conversion costs low. Sch 20, being a lighter wall, is produced less frequently and in smaller batches, driving up unit cost.

2. Billet-to-Pipe Yield

Heavier schedule pipes consume more steel per meter but achieve better material yield ratios in the piercing and elongation process. The billet yield for Sch 160 pipes is often more predictable, keeping scrap rates low and thus per-kg cost competitive relative to weight.

3. Market Demand & Inventory Cycles

Large bore pipes (350 NB and above) are produced on order or in limited stocking quantities. When project demand spikes — particularly from refineries or water infrastructure projects — lead times extend and spot prices rise. The ₹90–₹105/kg band for 400–500 NB sizes in May 2026 reflects continued demand from major pipeline and refinery turnaround projects across India.

4. Small Bore Premium

Sizes 15 NB to 32 NB carry a significant premium (₹90–₹160/kg) because the piercing process is more material-intensive relative to finished pipe weight, rejection rates are higher, and demand from instrumentation, hydraulic, and mechanical applications keeps the market tight.

Buying Guide: How to Get the Best A106 Gr B Seamless Pipe Price in India — May 2026

1. Know Your Required Schedule Before You Enquire

The wall thickness (Schedule) drives price more than size in many cases. If your design allows either Sch 40 or Sch 80, get prices for both — in the 50–150 NB range, the per-kg rate is identical (₹75/kg as of May 2026), but Sch 80 gives you more metal per meter and better pressure rating. For critical service, always specify the schedule in your enquiry; do not leave it to interpretation.

2. Buy by Weight, Not by Piece

Seamless pipes are priced per kg. Always confirm the theoretical weight per meter using ASME B36.10M data for your NB and schedule, then multiply by the required length and add a 2–3% cutting/handling allowance. This prevents short deliveries and over-ordering.

3. Request a Binding Quotation with MTCs

Indicative market prices (like those in this list) are the starting point. For order placement, always request a formal written quotation with price validity, delivery schedule, payment terms, and confirmation of MTC availability. This protects you from price variation between enquiry and invoice.

4. Consider Full-Container-Load (FCL) Buying for Large Projects

A 20-foot container holds approximately 18–22 MT of pipes depending on size and packing. If your project requirement exceeds this threshold, negotiating an FCL mill-direct shipment can save ₹3–8/kg versus buying from a stockist. This is particularly impactful for export orders where freight optimization is critical.

5. Verify the Price Includes — or Excludes — These Elements

• GST (18%) — always confirm whether the quoted price is inclusive or exclusive
• Freight to your site or port — road freight adds ₹1–8/kg depending on distance and size
• Third-party inspection charges — typically ₹8,000–₹25,000 per inspection lot, charged separately
• Special packing charges for export — sea freight packing adds ₹2–5/kg for large orders
• Certificate charges — some mills charge for EN 10204 3.2 certificates separately

Frequently Asked Questions — ASTM A106 Grade B Seamless Pipe

What is the current price of ASTM A106 Grade B seamless pipe per kg in India — May 2026?

As of May 2026, ASTM A106 Grade B seamless pipe (Indian make) is priced between ₹75/kg and ₹160/kg, depending on nominal bore (NB) size and wall thickness (Schedule). Mid-range sizes from 50 NB to 150 NB in Sch 40, 80, and 160 are currently at ₹75/kg. Small bore sizes (15–32 NB) attract premiums of ₹90–₹160/kg, while large bore sizes (400–500 NB) range from ₹90–₹105/kg. All prices are exclusive of GST.

What is the difference between ASTM A106 Grade B and Grade A seamless pipe?

Grade A has a lower minimum tensile strength (330 MPa vs 415 MPa for Grade B) and lower yield strength (205 MPa vs 240 MPa). Grade B is significantly more common and is specified for most high-pressure and high-temperature applications. Grade A is occasionally used in lower-pressure piping where the extra strength of Grade B is not required. In practice, most Indian mills stock and supply Grade B as the default; Grade A is made to order.

Is Indian-make A106 Grade B seamless pipe accepted on international projects?

Yes. Indian seamless pipe mills — including Jindal SAW, Maharashtra Seamless, and other major producers — are approved vendors for EPC contractors executing projects under ASME, API, and EN standards across the Middle East, Africa, and South-East Asia. Mill Test Certificates (EN 10204 3.1 and 3.2) from approved Indian mills are accepted by major oil companies (Aramco, ADNOC, QatarEnergy, ONGC) and international EPCs (Larsen & Toubro, Samsung E&C, Technip, etc.).

What is the minimum order quantity (MOQ) for A106 Grade B seamless pipe from India?

For stockist supply (ready stock), there is typically no minimum order — you can buy a single length (6 m or 12 m). For mill-direct orders, the MOQ is generally 1 MT per size and schedule for standard sizes, rising to 3–5 MT for non-standard OD/WT combinations. For export orders, the practical minimum for cost-effective shipping is approximately 5 MT (grouping multiple sizes in one container). Contact us for flexible small-quantity supply from our Mumbai stockyard.

How long does delivery take for A106 Grade B seamless pipe in India?

For standard sizes from stockist inventory in Mumbai and major cities: same-day to 3 working days. For mill-direct supply of standard sizes: 3–6 weeks from order confirmation. For non-standard OD/WT or special heat treatment requirements: 8–14 weeks. For export orders, add 2–3 weeks for pre-shipment inspection, documentation, and port logistics. Plan your material schedule accordingly and always confirm delivery timelines in the purchase order.

Are prices in this list inclusive of GST?

No. All prices in this price list are exclusive of GST. As of May 2026, seamless steel pipes attract 18% GST in India. Add 18% to the quoted per-kg rate to arrive at the inclusive price. GST input tax credit (ITC) is available to registered businesses. For export orders (zero-rated supply), GST is not applicable and exporters can claim refund of GST paid on inputs.

What is SMLS Pipe 106 GRB?

SMLS Pipe 106 GRB is the trade shorthand for Seamless (SMLS) Pipe, ASTM Standard 106, Grade B (GRB). This abbreviation is commonly used in Indian steel market price lists, mill invoices, and purchase orders. It refers to the same product as "ASTM A106 Grade B Seamless Pipe" or "ASME SA106 Grade B Seamless Pipe."
