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.
Pourin is equipped with a complete set of high automation and precision coil production lines including: tube end pretreatment, three-dimensional storage storehouse, straight pipe butt welding machine, flaw detection system, pipe bending platform, controlling good quality of tube ovality and thickness thinning.
After more than 10 years of exploration and continuous improvement, currently, Pourin is one of the global largest, standardized, and professional cladding manufacturer of boiler anti-corrosion and anti-erosion. The membrane wall weld overlay equipments are completely developed by Pourin. From design, manufacture, installation, commission and production each step has been constantly improved. At present, Pourin’s membrane wall panel cladding equipments leading the world in technology advancement, quality reliability and production efficiency.
