ASTM A106 Grade B Pipe `Stainless Steel Alloys

SA106 Grade B Seamless Pipe Supplier, A106 Grade B Welded Pipes Exporter in India
A106 Grade B ERW Pipe Stockist, ASTM A106 GR. B Carbon Steel Pipe
ASTM A106 grade B Pipe is used in power plants, boilers, petrochemical plants, oil and gas refineries, and ships for transporting hot or cold liquids and gasses under high pressures and temperatures.

At Steel Alloys , we supply ASME SA106 grade B pipe that meets the latest chemistry standards. Steel Alloys is the world’s supplier exporter, and wholesaler of ASTM A106 grade B pipes in India and globally.

Here are the available dimensions for A106 pipes:

● NPS (Nominal Pipe Size) from ¼” to 30” diameter
● Schedules 10 through 160, STD, XH, and XXH
● Wall Thickness up to XXH, including:
○ Up to 4” wall thickness in 20” through 24” OD
○ Up to 3” wall thickness in 10” through 18” OD
○ Up to 2” wall thickness in 4” through 8” OD

ASTM A106 Seamless Pressure Pipe covers seamless carbon steel pipe suitable for high-temperature service, allowing for bending, flanging, and similar forming operations. Pipes with NPS 1-1/2″ or below may be hot finished or cold drawn, while NPS 2″ or larger are typically hot finished unless specified otherwise. The weight of each pipe length does not vary more than 10% over or 3.5% under the specified amount. Larger sizes are weighed individually by length.

ASTM A53 grade a vs b

A53 Pipe vs A106 Pipe – (1) Scope

ASTM A53 is Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless.
ASTM A106 is Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service.

A53 Pipe vs A106 Pipe – (2) Applied Type of Pipe

A 53 can be welded seam or seamless depending on how it is specificed for purchase. It is a general steel pipe spec and covers galvanized pipe as well as black pipe.
A106 is a similar pipe in chemical composition but is intened for high temperature service (up to 750 Degs F). It is a seamless pipe.
At least in the US, there is usually A53 for welded pipe while A106 is seamless. If you ask for A53 in the US they will quote A106 as an alternate.

A53 Pipe vs A106 Pipe – (3) Chemical Composition

For example when we compare between A106-B and A53-B seamless from chemical composition point of view, we find that :
1. A106-B contains silicon, min. 0.10% where A53-B has zero%, and silicon is the important element for improving the heat resistance criteria.
2. A106-B contains manganese 0.29-1.06%, where A53-B 1.2%.
3. A106-B contains low sulfur and phosphorus, max. 0.035% where A53-B contains 0.05 and 0.045% respectively.
