Elbows are structures that are used before changing the direction of the pipeline. They have a curved appearance and different angle. Bends are created on special tube bending machines. Installation is carried out by welding. These products take on serious loads, as they are most often used for:
To protect them from destruction, they undergo special galvanizing, that is, a certain layer of zinc is applied to the metal, which increases the anti-corrosion properties and prolongs the service life. The main advantages of the processed products include:
To date, the galvanizing of the withdrawal is conducted only on proven technologies. The company "ElectroZincInstallation" uses such methods of galvanizing:
Each method has its own characteristics and is performed under certain conditions.
This technology involves the use of galvanizing taps slightly acidic electrolytes, where the anode acts zinc. During the deposition of atoms on the metal layer remains zinc thickness of 5 to 20 microns. This method has found application for processing of pipe products. During the execution, the outer part of the tap is processed, but the inner part is not covered by a protective layer as a result of the absence of an electric field.
Over the past year has become relevant. Parts are covered with zinc during the rotation of the parts in the container. The outlet is covered with a mixture of aluminum oxide, zinc and aluminum chloride. The item is in a container from 2 to 8 hours and at a temperature of +500°C. during diffusion, zinc atoms create a layer with a thickness of 20 microns to 60 microns.
This method is the most popular. Galvanizing of taps is carried out on a pre-prepared surface. She is degreased and etched. After processing and the part is immersed in the molten zinc composition with a temperature of +450°C...+460°C. to create a uniform coating basket with the part rotates or vibrational movements are performed.
