Welded

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 resistance and high reliability. Features are that welding line is uniform, high pressure resistance. 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：CO2 shielded arc welding--mainly used for piping with lower pressure. The advantages are easy operation, high efficiency and lower cost.

      Surface treatment: galvanized, phopshated, spray paint and spray plastic
