Material & Mechanical Properties
Chemical Composition (Typical Examples)
•ASTM A192 / ASME SA192: Low carbon steel optimized for excellent weldability and thermal conductivity. (C: 0.06-0.18%, Mn: 0.27-0.63%, Si: max 0.25%).
•ASTM A210 / ASME SA210 Grade A-1 & C: Medium carbon steel for higher tensile strength requirements in high-pressure boilers.
Mechanical & Performance Testing
Every single batch undergoes rigorous testing before leaving our facility to eliminate any risk of onsite failure:
•Tensile & Yield Strength Test: Ensures high load-bearing capacity under thermal stress.
•Flattening & Flaring Test: Validates superior ductility and flawless bending/shaping capabilities.
•Hydrostatic Test or 100% Non-Destructive Eddy Current Testing: Guarantees zero leakage and absolute seamless integrity.
Primary Industrial Applications
Our seamless carbon steel boiler tubes are the preferred choice for critical heat-exchange and fluid-conveying equipment worldwide:
•Power Plants: High, medium, and low-pressure steam boilers, superheaters, and reheaters.
•Petrochemical & Refining: Heat exchangers, condensers, and high-temperature pipeline systems.
•Mechanical & Engineering: Marine boiler manufacturing, locomotive boilers, and pressure vessels.
•HVAC & Energy Systems: Industrial furnaces and waste heat recovery units.

FAQ
Q: Can you provide Mill Test Certificates (MTC) with the shipment?
A: Yes, every batch of our carbon steel boiler seamless tubes comes with a standard Mill Test Certificate compliant with EN 10204 3.1. Third-party inspections (SGS, BV, TUV) can also be arranged and certified under EN 10204 3.2 upon request.
Q: What is your typical lead time for an export order?
A: For standard sizes available in our 5,000-ton rolling stock, we can ship within 7–10 days. For custom production runs involving specific custom lengths, special wall thickness, or unique heat treatments, the lead time generally ranges from 25 to 40 days.
Q: How do you prevent rusting during ocean freight?
A: All our boiler tubes undergo mandatory surface treatment-either an eco-friendly anti-corrosion black varnish or light oil coating-complemented by waterproof woven wrapping and heavy-duty secure bundling to withstand high humidity during long-term maritime transit.
Q: Do you accept small trial orders or flexible MOQs?
A: Yes, we understand that industrial projects require material validation. We offer flexible Minimum Order Quantities (MOQs) for trial orders if the requested specifications match our current rolling schedule or stock items. Please contact our sales team to check availability.
