![]() ![]() ASTM A106 pipe applicationĮspecially for high temperature services that up to 750☏, and it could substitute ASTM A53 pipe in most of the cases. Electric application: Gas transmission, water power generation fluid pipeline.Ĥ. Bearing sets, machinery parts processing.ģ. Construction, underground transportation, extraction of ground water while building, steam water transportation etc.Ģ. Applications for both standardsīoth pipes applied for mechanical and pressure systems, transporting steam, water, gas, and etc. Differences on mechanical properties ASTM A53 Grade B mechanical strength is same with ASTM A106 Grade B pipe.įrom below table listed the differences on chemicals for the three similar pipe:Īs ASTM A106 B is the common use, the chemical here we listed is C≤0.3%, Mn 0.29-1.06%, P≤0.035, S≤0.035%, Si>0.1, Cr≤0.40, Cu≤0.40, Ni≤0.40, Mo≤0.40, V≤0.08.ĭifferently with ASTM A53 B, ASTM A106 B has Si min 0.1%, which A53 B has 0, so A106 B have better heat resistance than A53 B, since Si improve the heat resistance.Ī106 Grade B has low sulfur and phosphorus than A53 B, this is better. Minimum tensile strength 70000 Psi or 485 Mpa, yield strength 40000 Psi or 275 Mpa. Minimum tensile strength 60000 Psi or 415 Mpa, yield strength 35000 Psi or 240 Mpa. Minimum tensile strength 48000 Psi or 330 Mpa, yield strength 30000 Psi or 205 Mpa.Ī106 Grade B: Maximum C below 0.30%, Mn 0.29-1.06%. ![]() Grade in A, B and C.ĪSTM A106 Grade A: Maximum Carbon element 0.25%, Mn 0.27-0.93%. ASTM A106 steel pipe types and gradesįor ASTM A106 steel pipe, manufacturing Type only in seamless, processes hot rolled and the cold drawn. ![]() According the facility from the manufacturer, type E of ASTM A53 pipe could be supplied non cold expanded or cold expand steel pipe.) A53 B Chemical and mechanical propertiesĪSTM A53 Grade B chemical properties content C≤0.30%, Mn≤1.2%, P≤0.05%, S≤0.045%, Cr≤0.40, Cu≤0.40, Ni≤0.40, Mo≤0.40, V≤0.08.ĪSTM A53 B mechanical strength is the same with ASTM A106 B steel pipe, Tensile strength maximum 415 Mpa, Yield strength maximum 240 Mpa.Įlongation: For A53 pipe there are 2 methods to calculate elongation.Ī: Use equation: e = 625 000 A^0.2/U^0.9ī: See ASTM A53 elongation value table X4.1 or table X4.2 for different specimen area. Although, it is not prohibit to use ASTM A106 Grade B for the cold bending and coiling. ![]() (Please note the type F is not used for flanging, and if type S or type E is applied for coiling or cold bending, it is recommended to use ASTM A106 Grade A pipe. In case ASTM A53 B pipe in cold expanded, then expansion should not exceed 1.5% of the required OD. In this way the no untempered martensite remains. In case ASTM A53 Grade B in ERW (electric resistance welded) pipe, the weld seam shall be done the heat treatment with a minimum 1000☏ . And the manufacturer should remove the transition material with the processes that could separate the grades positively. If raw steel material of different grades in process of continuously casting, the transition material result shall be identified. Different types and grades for both standard ASTM A53 steel pipe types and gradesįor ASTM A53 there are ERW and seamless steel pipes Type F, E, S covers Grade A and B.Ī53 Type F, furnace butt welded, continuous weld Grade AĪ53 Type E, Electric resistance welded (ERW), in Grade A and Grade B.Ī53 Type S, Seamless steel pipe, in Grade A and Grade B. Diameters range from NPS 1⁄8 to NPS 26 (10.3mm to 660mm), nominal wall thickness.ĪSTM A106 standard specification covers the seamless carbon steel pipe, applied for high-temperature services. Surface natural, black, and hot-dipped galvanized, zinc coated steel pipe. ASTM A53 specification covers the steel pipe manufacturing types in seamless and welded, material in carbon steel, black steel. ![]()
