A178 GR.D Welded Carbon Steel Pipe
A178 Steel Pipe is manufactured using high-quality raw materials sourced from reliable and trustworthy vendors of the industry. These products undergo various heat treatments and testing procedures to verify that they comply with specified properties.
A178 Grade D carbon-manganese steel boiler tube sizes and thicknesses generally conforming to this specification are 1 ⁄ 2 to 5 inches. After outer diameter 12.7 to 127 mm, A178 GR.D steel pipes should be heat treated at 900°C or higher and then cooled in the air or in the cooling chamber of a controlled atmosphere furnace, A178 GR.D cold Extubation should be heat treated after final cold drawing at 650°C or higher.
A178 GR.D high temperature pipe is mainly used in facilities requiring high temperature performance and high pressure corrosion resistance such as boiler pipes, radiators, superheaters and pressure equipment.
