Before Plate blanking, it needs leveling, to ensure the accuracy of materials. We use CNC plasma cutting machine and CNC flame cutting machine to ensure that the plate blanking size of the accuracy of ±1.5mm.
We have various Bending Machine, and the use of the largest 4000 tons CNC press (Model: W67K-4000/12500) to complete the bending of steel pipe; Multi-standard, adjustable mold to meet the different diameter of the steel pipe manufacturing.
To ensure accuracy, we use CNC plate production line manufacturing the welding of steel pipe support. Firstly small drill makes positioning hole, and then drill hole to the required diameter to make sure the whole precision.
We use vertical lathe for fine finishing of the cylindrical and end face of the flange, then the test is carried out to ensure that the surface is smooth, flat, burr-free and cracked. Using mechanized assembly to ensure the size of the assembly pipe fittings are accurate and reliable.
Production of each tower must be carried out test assembly, using vertical sub-assembly, to ensure the continuity of the tower. Before shipment, we have a final inspector manager to check the products on every detail and component to make sure it all meet the drawing.
