Hebei Bohai Pipe Co., Ltd. specializing in the production of 20 carbon steel elbow. Buy 20 carbon steel elbow went to Hebei Bohai Sea. Large steel elbows Category: Product Specifications: DN50-DN10001, in order to divide the material of carbon steel, cast steel, alloy steel, stainless steel 20 # carbon steel elbow, copper, aluminum, plastic, argon Ge Lek, ppc and so on. 2, production methods can be divided into pushing, pressing, forging, casting and so on. 3, in order to create a standard can be divided into GB, electricity standard, water standard, American Standard, the German standard, Japanese standard, the Russian standard and so on. Bohai on the large 45-degree elbow pipe product quality will we know the importance of a business, for which we strictly follow the standards of production, starting from raw materials, production processes for each of the steps of the quality tracking control, ensure that the factory every product reaches a hundred percent qualified, through management review, internal quality audits, process control, and self-improvement mechanism to take corrective and preventive measures, encourage enterprises to continuously improve the quality management system, quality assurance capabilities to enable enterprises to continuously strengthen 180 of 20 # carbon steel elbow, gradually increase the level of product quality, year to a new level. Cangzhou Bohai Pipe Co., Ltd. specializing in the production of carbon steel elbow 20, 20 steel elbows must be considered when designing and manufacturing steel elbow stiffness, how to improve the hardness of carbon steel elbow, through research we found that carbon steel elbow the need for heat treatment process, let's take a look at the heat-treated carbon steel elbow on some knowledge, carbon steel elbow heated to a certain temperature and maintained over time the price of 20 # carbon steel elbow, then it slowly cooled, called annealing. Annealing the hot steel elbow is heated to a phase change or phase transition temperature of the part of the production of carbon steel elbow 20 #, the heat treatment method of slow cooling after incubation. The purpose of annealing is to eliminate organizational shortcomings, improve the organization to make uniform structure and grain refinement to improve the mechanical properties of hot elbow, reduce the residual stress. 20 carbon steel elbow is forging steel molding or thermoforming diameter pipe, which is connected directly to the form diameter welded pipe and tube, concentric reducer main manufacturing standards generally GB / T12459, GB / T13401, ASME B16.9, SH3408, SH3409, HG / T21635, HG / T21631, SY / T0510. And concentric reducer eccentric reducer as well as corresponding materials are carbon steel, alloy steel and stainless steel. 20 carbon steel elbow widely used in piping system welded elbow oil, gas, chemicals, utilities, construction and boiler industry, the molding process is complex, the need for welding according to different materials and uses in certain It was taking shape under pressure. 20 # carbon steel elbow price, 20 # carbon steel elbow, Cangzhou Bohai Bohai Sea by Cangzhou Pipe Co., Ltd.. Cangzhou Bohai Tube Co., Ltd. (www.czbh628.com) (www.hbbh628.com) strong, credible, three-way, etc. Hebei Cangzhou accumulated a large number of loyal customers.
