Automatic pin tube welding machine will be a series of cylindrical welding on the surface of the steel pipe， its characteristics are: 1， quadrilateral circumferential equal distribution of welding 2， hexagonal circumferential equal distribution of welding

Compared with the traditional needle-shaped tube manufacturing process， quadrilateral， hexagonal needle-shaped tube to strengthen the heat transfer element， using welding a molding， change the past welding after the use of tooling forced stretching molding after the welding pin has fallen off phenomenon， so that the needle-shaped tube welding more solid， welding pin is not easy to fall off. Needle-shaped tube welding needle， diameter， length， longitudinal spacing， circumferential welding needle pin number and pin inclination are factors that affect the heat transfer of the needle-shaped tube. Therefore， it must be considered comprehensively and systematically in order to have more practical application. The use of four-sided and six-sided circumferential equal distribution of welded and needle-shaped tube， with a larger expansion surface， and needle-shaped tube on the fluid has a disturbing effect， can significantly improve the heat transfer coefficient， especially for high viscosity oil， heavy oil and other media to strengthen the heat transfer occasions.
