What is ERW Pipe? The Complete Guide from a Factory Perspective
By understanding the manufacturing process, standards, and applications of ERW steel pipes, you can save your project from high costs without compromising on quality.
ASTM A106 Grade B Seamless Pipe is a specification and grade for high-temperature, high-pressure carbon steel pipes. The A106 Grade B Seamless Pipe is used in applications where hot gases and fluids are transported at elevated temperatures.
This A106 Seamless carbon steel pipe is ideal for oil and gas refineries, power plants, petrochemical plants, boilers, and ships.
ASTM A106 Grade B Seamless Pipe is a specification and grade for high-temperature, high-pressure carbon steel pipes. The A106 Grade B Seamless Pipe is used in applications where hot gases and fluids are transported at elevated temperatures.
This A106 Seamless carbon steel pipe is ideal for oil and gas refineries, power plants, petrochemical plants, boilers, and ships.
The A106 Grade B range is completely seamless with wall thicknesses varying from schedule 40 to schedule 160 with weights ranging from Standard, Xtra Strong to Xtra-Xtra strong. All of the A106 Grade B pipes are recyclable, complete with Plain Ends.
ASTM A106 and ASME SA106 seamless pressure pipe is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

Surface: Lightly oiled, Hot dip galvanized, Electro galvanized, Black, Bare, Varnish coating/Anti rust oil, Protective Coatings (Coal Tar Epoxy, Fusion Bond Epoxy, 3-layers PE)
Test: Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test, Hardness Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, NDT TEST ( ET TEST, UT TEST)
1. High-Temperature Resistance: ASTM A106 Grade B tubes are specifically designed to withstand high temperatures, making them suitable for use in applications involving elevated operating temperatures.
2. Superior Strength: These tubes exhibit exceptional tensile strength and yield strength, ensuring structural integrity and longevity even in demanding conditions.
3. Corrosion Resistance: ASTM A106 Grade B tubes provide good resistance to corrosion, enhancing their durability and performance in corrosive environments.
A106 Grade B Seamless steel pipe, Suitable for applications which involve the transfer of fluids and gases at high pressure and temperature levels.
such as:
The ASTM A106 Grade B Seamless steel pipe is widely applied in petroleum, chemical engineering, boiler, power station, ship, machinery manufacturing, automobile, aviation, aerospace, energy, geology, architecture, military industry different industries. This seamless steel tube could also be used for manufacturing structural parts and mechanical parts, with regard to petroleum drill pipe, auto transmission shaft, bicycle frame and steel scaffolding in construction.
| Grade | Application | Temp Range | Key Features |
| A106 | Boilers, refineries | Up to 750°F | High temp & pressure resistance |
| A53 | Water, steam, air lines | Up to 550°F | Versatile, economical |
| API 5L | Oil & gas pipelines | Varies | Seamless flow, corrosion resistance |
| A333 | Low-temp service | -50°F to +650°F | Toughness in sub-zero conditions |
In order to increase the resistance of steel pipe in corrosive environment, we offer different types of coating systems to protect against corrosion and abrasion break.

The difference between ASTM A333 steel pipe and ASTM A106 steel pipe is that ASTM A333 is a low-temperature carbon steel pipe that can be used as a structural pipe, while ASTM A106 is a non-structural carbon pipe that is used in high-temperature applications.
Carbon steel pipe/ tube, also called CS pipe, are widely used in heavy industries like infrastructure, shipping, stills, mineral, oil, gas, and fertilizer industry pipeline systems.
Hot rolled seamless pipe is processed at high temperatures, resulting in a rougher surface and looser tolerances but lower cost. Cold drawn seamless pipe undergoes further processing at room temperature, delivering tighter tolerances, higher strength, and a smooth finish, though at a higher price point.
