aluminium coated tubes

High frequency welding machine of molding process is what? To make a clear people, see things, high-frequency welded pipe sales know what they need, step by step toward the goal. The molding technology of tube machine is selling a step in the high frequency welded pipe, clear the option can be achieved.
High frequency welding machine has two kinds of different molding methods: "after welding, molding," the first welding into a circular tube, a special-shaped pipe again. Such as machine, rectangular tube, oval tube, steel aluminium coated tubes window, etc. The advantages of this method is that in several kinds of steel pipe production, when allowed to strip size uniform, only need to welded pipe, a set of roll and being different in the framework of fixed diameter section. Hf hanguan sales think this pass system is simple, can greatly reduce the roll processing. Defect is due to the deformation is serious, pipe diameter is serious, the load is greater than the forming stands of mill load. Molding before welding. Complex cross section profile tubes could not be gotten from the pipe deformation, direct mould pressing and welding is required.
Has the advantage of direct forming, as long as the number of forming framework designed to meet the requirements of deformation by the shape of the product is not restricted. As a result, the high frequency welded pipe sales found that with the development of products, welded pipe unit forming the Numbers continue to increase. From forming to finish machining, the frame deformation load is stainless steel tube 304 roughly balanced. In this way can give full play to the performance of the welded pipe equipment. Its disadvantage is that the roll processing quantity is very large. High frequency welding machine of molding process is what? If you want to know your own needs, you will know what kind of high frequency welding machine is good.
With the widely application of the straight seam welded pipe, more and more people choose straight seam welded pipe. The straight seam welded pipe production technology is simple, high production efficiency, low cost, rapid development. Straight seam welded pipe cleaning and maintenance method: general requirements on the surface of the straight seam welding control nearly white level (Sa2.5 practice has proved that in the straight seam welding intervene with a common, vinyl, epoxy phenolic anticorrosive coatings, such as construction technology. Adopt the descaling grade removes almost all of the scale, rust and other debris and anchor pattern depth of 40 ~ 100 microns to fully satisfy the requirement of the anticorrosive layer and steel adhesion, and shot derusting spray (cast) process can be used with low running cost and stable and reliable Cold Drawn Seamless Tubes quality level to nearly white (Sa2.5 technical conditions. Certain rust occurs when the straight seam welded pipe, processing according to certain rust removal way and method, ensure the quality of the straight seam welded pipe and performance, can be used in different industries and priority fields, making important contribution and role for building industry.
