ASTM A135 Grade B Tubes & Pipes | ASME SA135 Grade B Tubes Supplier

ASTM A135 Grade B Tubes Manufacturer & Supplier in India

Solitaire Overseas is one of the manufacturers and suppliers of quality ASTM A135 Grade B tubes and pipes. This product is a form of Electric-Resistance-Welded (ERW) steel pipe which is used to carry gas, vapour, water or other liquids. Our A135 Carbon Steel Pipes are known to be strong, reliable and able to perform well in all manner of industrial tasks, particularly fire protection systems. All the goods that we make are accurately in line with the ASTM A135 specifications and its counterpart, ASME SA135. The ASTM A135 standard has offered two grades of ERW steel pipes: Grade A and Grade B, with Grade B as the stronger alternative used in conditions that demand a stronger or a high grade. The major attribute of Grade B is that the weld seam is heat-treated following the welding to inactivate any untempered martensite, which prominently increases the strength of the pipe and prominence of ductility. This procedure is an important quality control step that renders Grade B a good option when it comes to high-pressure and critical applications.

FAQ’s About ASTM A135 Grade B Tubes

What is ASTM A135 material?

ASTM A135 is a specification for electric-resistance-welded (ERW) carbon steel pipes used in conveying gas, vapor, water, or other liquids. These pipes are available in Grade A and Grade B, offering excellent strength, weldability, and formability for mechanical and pressure applications.

What is ASTM A53 Grade B used for?

ASTM A53 Grade B is widely used for structural and pressure applications such as pipelines, steam systems, water transport, and gas conveyance. It is a carbon steel pipe known for its durability, corrosion resistance, and suitability for welding and forming operations.

What is ASTM A and ASTM B?

In ASTM standards, “A” typically refers to ferrous materials like carbon or alloy steels, while “B” refers to non-ferrous materials such as copper, nickel, or aluminum alloys. These designations help categorize materials based on their composition and application in manufacturing and construction.
