In order to ensure the membrane wall panel dimension and welding beams quality, Pourin independently developed membrane wall panel machines, locates the tube and fin separately in the welding process, so as to make the membrane wall panel dimensions, e.g. the linear misalignment, length, pitch, straightness and flatness can be controlled in high precision. Operated by our professional technicians and engineers, the membrane water wall panel welding process are stable with smooth welding beams.
