Conveying seamless pipes are steel pipes formed by punching through round steel, with no welds on the surface. According to the production method, seamless pipes are divided into hot-rolled seamless pipes, cold-rolled seamless pipes, cold-drawn seamless pipes, and hot-expanded seamless pipes. Seamless pipes are classified into two types based on their cross-sectional shape: circular and special-shaped.

ASTM A106 Grade B Conveyor Pipe is a high-performance seamless carbon steel pipe designed for conveying materials, fluids, and gases under high temperature and high pressure conditions. Manufactured according to the ASTM A106 specification, this pipe is widely used in conveyor systems, mechanical structures, oil and gas pipelines, boiler tubes, and industrial processing equipment. Its excellent mechanical properties, reliable strength, and high corrosion resistance make it a preferred choice in both industrial and structural applications.

Material and Manufacturing Process

ASTM A106 Gr.B pipe is produced from high-quality carbon steel billets through a hot rolling or cold drawing process, ensuring a uniform structure and superior mechanical performance. The chemical composition typically includes carbon, manganese, phosphorus, sulfur, and silicon, carefully balanced to provide optimal toughness and strength.

The pipes undergo nondestructive testing, hydrostatic testing, and dimensional inspections to guarantee compliance with international standards. This ensures consistent quality and performance in demanding conveyor and pressure applications.

Mechanical Properties

The mechanical strength of ASTM A106 Grade B is one of its most valuable features.

Tensile Strength: ≥ 415 MPa (60,000 psi)

Yield Strength: ≥ 240 MPa (35,000 psi)

Elongation: ≥ 20%

These properties give the pipe excellent durability under mechanical load and temperature fluctuations. It performs well in both low- and high-temperature conditions, making it suitable for steam lines, conveyor systems, and industrial piping networks.

Dimensional Range and Standards

ASTM A106 Gr.B Conveyor pipes are available in a wide range of sizes, wall thicknesses, and lengths. Common outside diameters range from 1/2 inch to 24 inches, with schedules SCH 40, SCH 80, SCH 160, and XXS available.

All pipes are supplied with plain ends (PE), beveled ends (BE), or threaded ends (TE), depending on project requirements. Dimensional tolerances strictly follow ASME B36.10M and ASTM A530/A530M standards.

Applications in Conveyor Systems

As a conveyor pipe, ASTM A106 Grade B is often used in material handling systems, where it serves as a key component in transporting bulk materials such as coal, ore, cement, and grain. Its smooth inner surface ensures low frictional resistance, enhancing material flow and reducing energy consumption.

In mechanical conveyor lines, it provides stable structural support and wear resistance, extending the service life of the entire system. This makes it ideal for power plants, mining operations, steel mills, cement factories, and chemical plants.
