Precision Engineering for Demanding Conditions

The Round Thin Wall Seamless Carbon Steel Tube offers outstanding mechanical and structural integrity, with thicknesses ranging from 1mm to 30mm and diameters between 6mm and 350mm. Each tube undergoes rigorous quality testing, including chemical composition analysis, mechanical property testing (tensile, yield, elongation), hydrostatic testing, and nondestructive testing, ensuring consistent performance under extreme operating conditions.

These tubes are available in three grades — A, B, and C — each tailored for different industrial requirements.

• Grade A provides reliable performance for moderate pressure applications.

• Grade B delivers higher strength and durability.

• Grade C offers maximum tensile performance, with yield strength up to 275 MPa and tensile strength exceeding 485 MPa.

Superior Manufacturing and Surface Treatment

To ensure longevity and corrosion resistance, Wuxi Sylaith applies a variety of surface treatments including oil-dip coating, varnish, phosphating, passivation, and shot blasting. The tubes are delivered in annealed, normalized, or normalized and tempered conditions, depending on client specifications.

For added protection during handling and transport, all products are beveled, black-painted, and capped with plastic ends, then bundled with steel straps or packaged in wooden crates to prevent damage.

Versatile Industrial Applications

The ASME SA106 / ASTM A106 seamless carbon steel tubes are widely used for:

• Petroleum and natural gas pipelines

• Boilers and high-pressure steam systems

• Heat-supply and drainage systems

• Power generation and chemical plant infrastructure

• Pile driving and structural applications

Their thin-wall design offers excellent heat transfer properties and reduced weight, making them ideal for energy-efficient systems and modern industrial installations.

Stringent Quality Control and International Standards

All products are manufactured under strict quality supervision, adhering to ASTM, ASME, and GB standards. The tubes undergo multiple stages of inspection and testing, including:

• Hydrostatic testing for leakproof assurance

• Ultrasonic inspection for internal flaw detection

• Flaring and flattening tests to confirm ductility

• Mechanical property testing to verify tensile and yield strength

Wuxi Sylaith also welcomes third-party inspection by organizations such as SGS or BV to ensure transparency and customer confidence.
