Material Grade & Specification
The base material grade (e.g. IS 1239, ASTM A106, DIN 2391) directly impacts cost. Higher-grade alloy steels or specialized specifications carry a premium over standard mild steel.
Size — OD, Wall Thickness & Length
Outer diameter (OD), wall thickness, and cut length determine the weight per piece. Non-standard sizes may require mill-specific production, which affects pricing and lead time.
Quantity Ordered
Bulk orders get better per-MT pricing. We offer volume discounts starting from 5 MT for standard products. Repeat-supply contracts receive the best rates.
Source Mill & Brand
Different mills (Tata, JSW, Jindal, APL Apollo, etc.) have different base pricing. Premium brands may cost more but offer superior quality documentation and consistency.
Delivery Location & Transport
Freight costs vary by destination. Local Kanpur delivery is typically included, while interstate dispatch to UP, Bihar, MP, Delhi NCR incurs additional transport charges based on distance and weight.
Quote Validity & Market Conditions
Steel prices fluctuate daily based on raw material costs, demand cycles, and government policies. Our quotations are typically valid for 3–7 days depending on market volatility.
Weighment & Tolerance
In the steel pipe industry, billing is ultimately determined by weight. Understanding the difference between theoretical and actual weight matters for accurate budgeting. According to IS (Indian Standard) codes, a permissible rolling tolerance is allowed during manufacturing.
Theoretical vs. Actual Weight
Theoretical Weight: The mathematically calculated weight based on exact outer diameter (OD) and wall thickness (WT).
Actual Weight: The physical weight of the pipe when placed on a calibrated weighbridge. RP Sales bills on actual weight to guarantee 100% transparency.
IS Standards Tolerance
Most BIS standards (like IS 1239) allow a weight tolerance of ±8% to ±10% for single tubes. This means a pipe might be slightly lighter or heavier than the theoretical calculation while still being structurally certified and perfectly legal.
Example Invoice Calculation
- Order: 100 pipes of a specific size.
- Theoretical Weight: 25.0 kg per pipe. Total = 2,500 kg (2.5 MT).
- Actual Weighbridge Weight: Due to a -4% manufacturing tolerance, the actual batch weight is 2,400 kg (2.4 MT).
- Result: We bill you for 2,400 kg. You never pay for steel you don't receive.
