Pre-welding Preparation Requirements Pipe Inspection: Check the specifications, wall thickness and material of galvanized pipes before construction to ensure compliance with design requirements. The pipes shall be free from deformation, damage and severe corrosion with uniform and intact galvanized layers. Unqualified pipes are prohibited from welding. Groove Machining: For pipes with wall thickness \u2265 3mm, V-shaped grooves are required with a groove angle of 55\u00b0-65\u00b0 and a root face of 1-1.5mm.
