A192 Boiler Tubes are seamless carbon steel boiler tubes under the American Standard ASTM/ASME (ASTM A192/ASME SA192), designed for high-pressure boiler systems, suitable for severe working conditions with operating temperatures of 450℃~650℃ and pressures of ≤9.8MPa. It is suitable for severe working conditions with operating temperatures of 450℃~650℃ and pressures of ≤9.8MPa.
Chemical composition:
Low carbon steel (carbon content of 0.06%~0.18%), manganese content of 0.27%~0.63%, phosphorus and sulphur ≤0.035%, optimized for weldability and corrosion resistance, and corrosion resistance. and corrosion resistance.
Silicon content ≤0.25%, enhancing the deoxidation ability and material strength.
Mechanical properties:
Tensile strength ≥325MPa, yield strength ≥180MPa, elongation ≥35%, to ensure structural stability under high pressure.
Hardness requirements: tube diameter or wall thickness ≥5.1mm, Brinell hardness ≤137HB; wall thickness <5.1mm, Rockwell hardness Hardness requirement: Brinell hardness ≤137HB for pipe diameter or wall thickness ≥5.1mm; Rockwell hardness ≤77HRB for wall thickness <5.1mm
Application
High-pressure boiler components: used in key parts such as heated surface tubes, header boxes, economisers, superheaters, etc.
Heat transfer scenarios: play an efficient heat transfer role in high-temperature steam or heat transfer oil transmission in electric power, chemical industry, and other fields.
Specification parameters
Size range:
Outer diameter 12.7~177.8mm (1/2~7 inch), wall thickness 2.2~25.4mm, length up to 27m Processing Requirement: Seamless cold-drawn process.
Processing Requirements: Seamless cold-drawn process to ensure high precision (wall thickness tolerance ±10%) and surface finish.
