Technology is introduced: TIG welding —mainly used for piping with high working pressure. The advantages are reflected in single side welding and both sides forming , high pressure résistance and high reliability. Features are that welding line is uniform, high pressure résistance. It is durable and has the advantages of high pressure and no leakage. It is effectively applied to hydraulic lines of mechanical equipment with high vibration and high strength.
Application industry: C02 shielded arc welding—mainly used for piping with lower pressure. The advantages are easy opération, high efficiency and lower cost.
Surface treatment: galvanized, phopshated, spray paint and spray plastic
