Stainless steel electric-welded tubes, obtained by Gas-electric (argon-arc, plasma), welding cover the full range of small and medium-diameter stainless steel welded tubes for Responsible destination manufactured from high alloy steels. To obtain a firm and dense seam used the following methods of fusion welding: arc welding with inert gas arc protection, plasma welding. Received by these stainless steel pipes, electric-ways are the most popular assortment, but along with this popular assortments widespread osobotonkostennye stainless steel electric tubes, welded by these methods because of the fact that the process of manufacturing such pipes require special precision molding, and the precise control of thermal conditions of welding. Gas-electric (argon-arc, plasma) welding is based on the use of an electric arc is created due to the fact that one pole is located on the electrode in the form of non-consumable tungsten rod and the other pole is located on the edges of billet. Heat, which creates an arc that focuses on a small section billet edges in the combustion zone of the arc and causes rapid melting of these edges. In order for […]

The conveyor belt is the most wearable element of any conveyor belt, which certainly implies it the right choice for most long life. In this paper we suggest to familiarize with the basic parameters on which ought to pay attention to when selecting rubber conveyor belts of both domestic and foreign production. First of all, you have to determine the type of abrasive cargo that is transported on a conveyor belt: a non-abrasive (products of agriculture, sawdust, grain, piece goods, etc.) maloabrazivny (brown coal, sand, cement, gravel, etc.), grinding (ore, magnesite, gravel, etc. ) hIGh (Polymetallic ores, iron ore quartzite) Based on this, and of course the performance of the conveyor can choose the type of rubber-fabric conveyor belts, which are classified depending on the conditions operation in the following categories: Light duty for medium duty, heavy duty Rubber fabric conveyor belts in accordance with the standards and various specifications can be manufactured with special properties (heat, frost, kislotoschelochostoykie, etc.), it is also necessary to pay attention to the selection of tapes specifically for your environment operation. Remember that the […]
