ASTM A106 Grade A/B/C Pipe, Tubes

ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe) covers seamless carbon steel nominal wall pipe for high-temperature service. Suitable for bending, flanging and similar forming operations. ASTM/ ASME A106/SA106 Seamless Carbon Steel Pipe is heat resistant and ideal for industrial applications with elevated temperatures. ASTM/ASME A106/SA106 seamless carbon steel pipe is used in industrial applications involving high heat, including process piping, boiling plants, compression stations and refineries. The additional silicon boosts this product’s performance in high-temperature environments, such as steam lines and processing applications.

WHAT IS A106 PIPES?

ASTM A106 Pipe is the black carbon steel pipe for high-temperature, high-pressure service of seamless pipe in three grades A, B, and C of varying strength. ASTM/ASME A-106/SA-106 grade seamless Pipe is one of our most widely used grade of carbon steel and is readily available ex-stock for all standard thicknesses up to SCH160. NPS 1-1/2 and under may be either hot finished or cold drawn. NPS 2 and larger shall be hot finished unless otherwise specified. Surface finish standards are outlined in the specification.

ASTM A106 Grades A and B pipes are obtainable in most sizes and schedule numbers, ASTM A106 Grade B Pipe permits higher carbon and manganese contents than Grade A. The A106 Grade B supplied by ASTM Seamless Pipe has a maximum carbon content of 0.23%.

A106 PIPE VS A333

In one of our projects a large number of pipes and fittings of two carbon steel grades ( ASTM A106 Gr.c & A333 Gr.6 ) are mixed together by mistake. Unfortunately the color codes and other material codes of these materials diminished due to sand blasting of theire surfaces and we could not distinguish and seperate them. ASTM A 106 Gr C contains some unspecified elements such as Cr, Cu,Mo, Ni,V – ranging from 0.08 to 0.40% For Ex: Cr in ASTM Gr C could be max: 0.40 % Nickel: 0.40 %, Mo: 0.15% ASTM A 333 Gr 6 does not contain these unspecified elements. You can think of some Field Kit with chemial etchants with a low power battery with some standard test steel samples of the elements you would like to quickly analyze for this steel sorting of tubes

ASTM A 106 Gr C contains some unspecified elements such as Cr, Cu,Mo, Ni,V – ranging from 0.08 to 0.40% For Ex: Cr in ASTM Gr C could be max: 0.40 % Nickel: 0.40 %, Mo: 0.15% ASTM A 333 Gr 6 does not contain these unspecified elements.

A106 PIPE VS A53

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.

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.

A106-B contains silicon, min. 0.10% where A53-B has zero%, and silicon is the important element for improving the heat resistance criteria. 
A106-B contains manganese 0.29-1.06%, where A53-B 1.2%. 
A106-B contains low sulfur and phosphorus, max. 0.035% where A53-B contains 0.05 and 0.045% respectively.

A106 PIPE DIMENSIONS

All Pipe is manufactured and inspected to the relevant standards including ASTM,ASME,API.

Wall thickness: The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified. 
Weights per foot: The weight of any individual length shall not vary more than 10% over and 3.5% under that specified. NOTE – NPS 4 and smaller are weighed in lots. Larger sizes are weighted by individual length. 
Outside diameter: Shall not vary from standard specified below at any point.

A106 PIPE MATERIAL

ASTM A106 pipe is always produced by the seamless method and can be bent, coiled and flanged. In sizes less than 2″ is it usually produced as a cold drawn product. 2″ and up are usually hot finished. ASTM A106 pipe is intended for use in high temperature applications. A106 Gr. B is intended for high temperature service (up to 750 Deg F). It just applies to seamless steel pipe with killed steel. Pipe of NPS 1 1/2” and under may be either hot finished or cold drawn. Unless specified, pipe on and over NPS 2″ shall be furnished hot finished, while A53 and API 5L are not.
