The outer steel pipe used during construction is generally: φ48 × 3.5 steel pipe steel pipes shall meet the current national standards “straight seam welding steel pipes” (GB/T 13793) or “low -voltage fluid transportation steel pipe” (GB/T 3092 ” ) The quality specified in the 3rd of the 3rd steel pipe shall meet the provisions of the Q235-A-A-A steel in the current national standard “Carbon Structure Steel” (GB/T 700). The standard parts manufactured by forged cast iron shall be used to comply with the current national standard “Gb 15831). Attachment (T-shaped bolts, nuts, pads) of the fastening parts uses the material to comply with the provisions of Q235-A in the “Carbon Structural Steel” (GB/T 700).
