Alloy diameter pipe resistance of air, steam, water and other corrosive medium and weak acid, alkali, salt and other chemical etching medium corrosion of steel practical applications, often the weak corrosion medium corrosion of steel called alloy diameter pipe, and the chemical resistance of steel known as acid corrosion of steel. As the two differences in the chemical composition, the former does not necessarily chemical resistance corrosion, while the latter generally has a stainless steel sex. buy alloy reducers on both Hebei Qi Industry come together. Corrosion resistant alloy tube diameter depends on the alloying elements contained. Chromium is to corrosion resistance of stainless steel stamping elbow obtain the basic elements, when the chromium content in steel reaches containing about 1.2% chromium and corrosive media, role of oxygen in large-diameter eccentric reducer in the steel surface of a thin oxide film (from the passive film), can prevent further corrosion of the steel substrate. In addition to chromium, the commonly used alloying elements nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the various uses of the concentric reducer organization and performance requirements. the use of certain production and processing when concentric reducer production and ensure to show a good effect in the production and processing . and performance Chiho Hebei Industry; size head diameter pipe manufacturers of steel is characterized by intensity was significantly higher than the same amount of carbon in carbon steel, it has good toughness and ductility and good weldability and corrosion resistance. Reducing the size of the first manufacturers of carbon steel pipe made of carbon steel, representation is the largest diameter multiplied by the small head diameter. The size of the head of the raw material and process quality determines the size of the head size of the first manufacturers to present the process is generally repression, namely the raw materials, seamless cut a good length is generally longer than the national standard margin outflow turning eccentric reducer standard, Then pressing, pressing work is very technical content eccentric reducer, general level is adjustable for example 325 * 273 this type of size of the head can be no heating before direct compression eccentric reducer size, pressing because adjustable small, the material stress is also small, but must go through annealing, stress relief annealing process is completed after pressing the process, but there are many manufacturers of this work is not essential as will increase costs, but I think this behavior is undesirable, the national standard is justified, raw size of the head are generally seamless, but there are many manufacturers use but also the seamless use of all renewable waste pipe, we knows regeneration pipe material who do not know because there are big and small can not go to the big one by one and laboratory spectroscopy, high pressure mounds Jiuding Pipe Factory produced seamless size of the first all new material production, to ensure that the material at the source The stable, but our prices will be higher than the industry because they do is high-end customers. The size of the head of the packaging testing and marking: I plant the size of the head wants to go through rigorous testing before the appearance, materials analysis, like gold analysis and nondestructive testing, then that is sand-blasting paint marking meter storage.
