Adjustable stainless steel manufacturer adjustable elbow manufacturers, stainless steel elbow manufacturers preferred Hebei Thai Extension pipe factory, I plant has many years of pipe production history, adjustable elbow process, if done long radius elbow, to first select the size proposed pipe material. The expansion ratios, by theoretical calculations, the general expansion ratio between 33% -35%, down push back. Short Radius 219mm diameter expansion of the general rate of 50%. selected materials After pressing the elbow material specifications. Welcome to the new and old customers to inquire order. Stainless steel adjustable elbow purposes: connecting two tubes of different diameters, so that pipes for 90 ° turn while the narrow path. The production process used is the entire elbow tapered sliver draw processes to produce. The role is to make a 90 degree turn when the make-diameter pipe is changed. And the role of the head is the same size, but the size of the head can not do the steering. Price ratio of the diameter of the elbow is about to be about twice as high. In some of the construction site, on a bend and with a size of the first welded together into a place of this product. Its materials are carbon steel, stainless steel, alloy steel, PVC, steel and so on. The most common standards are the national standard GB / T12459-2005 and GB / T13401-2005. The main origin in Cangzhou City, Hebei Province Yanshan County area. Adjustable elbow molding process, also known as adjustable elbow reducing elbow, elbow with a standard billet cut into a V-shaped mouth of the elbow 15CrMo adjustable elbow, then pressure or by means of conventional Dynamic special stamping equipment, so bend the blank in the mold directly affected by the deformation force and deformation to obtain a certain shape, size and performance of the product components production technology, slowly becoming in effect a round under pressure to become a circular ring shell, welded 316L adjustable elbow, then bend the device and you're done. Adjustable elbow processing is a metal cold deformation processing methods. It is one of metal plastic processing (or pressure processing) of the main method, also attached to the material forming engineering techniques. Advantages of adjustable elbow production process advantages adjustable elbow production process mainly in the following aspects: 1. Need to bend blank as raw material, mold cost savings can be obtained in any caliber elbow. 2. blank blank adjustable elbow to elbow, so that work is simple, easy to ensure accuracy, easy assembly and welding. 3. Due to the above two reasons, it can shorten the manufacturing cycle, the production cost is greatly reduced.
