Excellent wear resistance, continuous use: Special ceramics wear-resistant equivalent to manganese steel 266 times times, by the middle-South industrial Large Powder Metallurgy Research institute. However, compared with the off-line heat treatment, the process of direct normalizing is simpler and the energy is saved. This method does improve the appearance of the elbow and can also provide a good value for the elbow. So enterprises in the production of elbow must be from the production mode and production quality, so as to bring the corresponding benefits to the enterprise. A slight difference in lateral shrinkage on the outside. Cold crack characteristics: from the cold crack production conditions and the formation of the reasons, it is different from other welding cracks. For welding flanges, different grades of pressure are produced. The inspection of appearance quality mainly refers to the inspection of the geometrical dimension, shape and surface condition of forgings. The internal quality inspection mainly refers to the chemical composition, macroscopic microstructure, microstructure and mechanical properties of forgings. The reducer flange is used for the connection between the motor and the reducer, and for the connection between the reducer and the other equipment.
Four-pass for pipe fittings, pipe connection pieces. Because of this special structure, it can not only process the right screw thread, but also can process the left screw thread, but not to the larger pitch thread processing. The selection of stainless steel pipe materials mainly from the following aspects: load-bearing, wear-resisting, corrosion resistance, impact resistance, high temperature and so on. China’s accession to gradually become a large international trade body, but also contribute to the expansion of the global economy, and the Asian economy has a great impact.
Carbon steel flange is a kind of common flange process, which has the advantages of high production efficiency and low production cost, and is suitable for medium and low pressure pipelines. The conventional test of heat treatment is usually done by hardness test. As usual, the welded pipe fittings are made of forgings or forged rolling process. Because of its advantages such as light weight, corrosion resistance, high strength and so on, it is widely used in piping installation. Any product can not be without defects, just try to control the product to the minimum, so the company in the production of slip on flange to improve the performance of the product, so that it plays to the greatest role. In addition, the ring section under the internal or external radial pressure, the force is more uniform, so most of the pipe is round pipe.
we have our own pipe fitting factory since 1998 ,which covers 100 acres. In 1998, we invested and set up a new flange factory. Up to now, we have a complete production system, and become a professional and competitive group in this field.
