Boiler Tube Price - Mill Direct ASTM Supplier | Kuaima Steel Group
Boiler tube price is a critical factor for procurement managers sourcing heat-resistant seamless and welded tubes for power generation, petrochemical processing, and industrial heating systems. At Kuaima Steel Group, we offer mill-direct boiler tubes manufactured to ASTM, ASME, EN, and GB standards, delivering cost-effective pricing without compromising on metallurgical quality. Whether you require carbon steel, alloy steel, or stainless steel boiler tubes, our vertically integrated supply chain eliminates middlemen and passes genuine savings directly to your project budget.
What Is a Boiler Tube?
A boiler tube is a seamless or welded steel tube engineered to withstand high-pressure steam environments and elevated operating temperatures. These tubes serve critical roles in water-tube boilers, fire-tube boilers, superheaters, economizers, and heat exchangers. Manufactured through hot-rolling or cold-drawing processes, boiler tubes must meet stringent requirements for creep resistance, oxidation resistance, and hydrostatic pressure tolerance as defined by standards such as ASTM A192, ASTM A213, ASTM A178, and EN 10216-2.
Boiler Tube Price — Key Factors That Influence Cost
Understanding what drives boiler tube price helps buyers make informed purchasing decisions. Several variables directly impact the final cost per meter or per ton:

- Material Grade: Carbon steel grades like SA192 (tensile strength ≥325 MPa) are more economical than alloy grades such as SA213 T11 (1Cr-½Mo) or T22 (2¼Cr-1Mo), which contain costly alloying elements like chromium and molybdenum.
- Manufacturing Process: Seamless boiler tubes command a premium of 15%–30% over ERW (Electric Resistance Welded) tubes due to superior pressure-bearing uniformity.
- Dimensions: Common outer diameters range from 15.88 mm to 114.3 mm with wall thicknesses of 1.5 mm to 12.7 mm. Thicker walls and non-standard sizes increase unit cost.
- Order Volume: Mill-direct pricing becomes significantly more competitive at volumes above 5 metric tons.
- Surface Finish and Testing: Requirements for pickling, phosphating, or additional non-destructive examination (NDE) such as ultrasonic testing per ASTM E213 add processing costs.
Boiler Tube Technical Specifications
Kuaima Steel Group supplies boiler tubes across a comprehensive range of international standards. Below are our most commonly requested specifications:
| Standard | Grade | OD Range | Wall Thickness | Yield Strength (min) |
|---|---|---|---|---|
| ASTM A192 | SA192 | 15.88–114.3 mm | 1.5–12.7 mm | 180 MPa |
| ASTM A213 | T11 / T22 / T91 | 12.7–127 mm | 2.0–14.0 mm | 205–415 MPa |
| ASTM A178 | Grade A / C | 15.88–76.2 mm | 1.5–6.0 mm | 180–255 MPa |
| EN 10216-2 | 16Mo3 / 13CrMo4-5 | 21.3–114.3 mm | 2.0–12.5 mm | 270–310 MPa |
| GB 5310 | 20G / 15CrMoG | 15–108 mm | 2.5–13.0 mm | 245–295 MPa |
All tubes undergo hydrostatic testing or non-destructive electric testing per applicable standard requirements, with flattening, flaring, and hardness tests performed as specified.

Frequently Asked Questions
What is the MOQ?
Our minimum order quantity for boiler tubes is 1 metric ton for standard grades. Non-standard alloy grades or custom dimensions may require a minimum of 3–5 metric tons to initiate a mill production run.
Do you provide material test certificates?
Yes. Every shipment includes EN 10204 Type 3.1 Mill Test Certificates (MTC) detailing chemical composition, mechanical properties, hydrostatic test results, and NDE records as applicable.
What is the typical delivery time?
Stock items in common grades like SA192 and 20G ship within 7–10 business days. Custom orders or alloy grades such as T91 typically require 25–35 days from order confirmation to ex-works readiness.
Can you cut to custom sizes?
Absolutely. We provide precision cutting to custom lengths ranging from 1 meter to 18 meters, along with beveling, threading, and protective end-cap services based on your project specifications.
