Product Description

Product Specification

ASTM A106 seamless pressure pipe (also known as ASME SA106 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.

ASTM A106 seamless pipes (also known as ASME SA106 pipes) are commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers and ships. These pipes must carry fluids that exhibit higher temperature and pressure levels And gas.ASTM A106 pipe includes three grades, A106 grade a, A106 grade b, and A106 grade c.

About ASTM A106 Gr B
ASTM A106 Gr.B seamless pipes (also known as ASME SA106 GR B pipes) is a cs seamless pipe nominal pipe for high temperature use.The chemical composition of  A 106 Gr.B is as follows:
C≤0.25, Mn=0.27-0.93, P≤0.035, S≤0.035, Si≤0.1, Cr≤0.4, Cu≤0.4, Mechanical properties: ób≥415/MPa, ós≥240/MPa.

About ASTM A106 Gr C
ASTM A106 Gr.C seamless pipes (also known as ASME SA106 GR C pipes) is a carbon-manganese steel pipe for high-temperature large-diameter boilers and superheaters. Its chemical composition is simple and similar to 20G carbon steel, but its carbon and manganese content is higher, so its yield strength is about 12% higher than that of 20G, and its plasticity and toughness are not bad. The steel has a simple production process and good cold and hot workability. Using it to replace 20G headers (economizer, water wall, low-temperature superheater and reheater header) can reduce the wall thickness by about 10%, which can save material costs, reduce welding workload, and improve headers The stress difference at start-up.

Manufacturing & Testing Requirements for A106 Seamless Pipes

Heat Treatment	Hot-finished pipe need not be heat treated. Cold-drawn pipe shall be heat treated after the final cold draw pass at a temperature of 1200 °F (650 °C) or higher.
Process	The steel shall be killed steel, with the primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining. If secondary melting, using electroslag remelting or vacuum-arc remelting is subsequently employed, the heat shall be defined as all of the ingots remelted from a single primary heat. Steel cast in ingots or strand cast is permissible. When steels of different grades are sequentially strand cast, identifi- cation of the resultant transition material is required. The producer shall remove the transition material by any estab- lished procedure that positively separates the grades.
Surface Treatment	Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting
Hydrostatic Testing	Inspection test pressures produce a stress in the pipe wall equal to 60% of specified minimum yield strength (SMYS) at room temperature. Maximum Pressures are not to exceed 2500 psi for NPS3 and must stay under 2800 psi for the larger sizes. Pressure is maintained for not less than 5 seconds.
Nondestructive Electric Test	The full body of each pipe shall be tested with a nondestructive electric test in accordance with Practice E 213, E 309, or E 570.
Mechanical Tests Specified	Tensile Test - NPS 8 and larger - either transverse or longitudinal acceptable smaller than NPS 8 - weighed in lots. Larger sizes - by length. Flattening Test - NPS 2-1/2 and larger. Bending Test (Cold) - NPS 2 and under.
