Square tube nonferrous metals, also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, tin, zinc aluminum, brass, bronze, aluminum alloy and bearing alloy. In addition, chromium, nickel, manganese, molybdenum, cobalt square tube, vanadium, tungsten, titanium, etc. are also used in industry. These metals are mainly used as alloy additives to improve the performance of metals. Tungsten, square tube titanium, molybdenum, etc. are mostly used to produce cemented carbide for tools. The above non-ferrous metals are called industrial metals. In addition, there are precious metals: platinum, gold, silver and rare metals, we need to select a suitable place. We need to think about many external factors, such as the corrosivity of steel pipe, etc. Therefore, the place must be clean, dry and ventilated, where harmful gases appear, QB square pipe can not appear weeds and other sundries should be removed in time, and the outer surface of steel should be kept clean. If there are acid, alkali, salt, it is easy to react with the steel pipe and corrode the steel pipe, so try to cut it and don't let it. In addition, if we can think about those higher metal products, we can put them into the warehouse for very good retention. According to geographical conditions, there is a sealed warehouse but the ventilation setting is excellent. The difference between QB square tube and seamless steel tube QB square tube is a kind of high-precision steel tube material after cold drawing or hot rolling treatment. QB square tube is mainly used to produce products of pneumatic or hydraulic components,Giovillanos150 hot dip galvanized pipe price, such as air cylinder or oil cylinder, which can be seamless pipe or welded pipe, because there is no oxide layer on the inner and outer walls of QB square tube, no deformation under high pressure, high precision, high finish, flaring and flattening without cracks. The chemical composition of QB square tube includes carbon silicon Si, manganese Mn, sulfur s, phosphorus P and chromium CR.Giovillanos,How to reduce the amount of oxide scale is the key to the heating operation of seamless square tube. Especially when it's hot. Starting from the service life of tools and the surface quality of pipes, the requirements are more stringent. For example, hot furnaces are divided into heating furnace and reheating furnace according to their functions; The former is used to heat the blank from normal temperature to processing temperature; The latter is used to reheat the blank to the necessary processing temperature during processing.Hot dip galvanized square pipe is widely used, mainly in curtain wall, solar power generation support, construction, machinery and steel structure engineering, especially in curtain wall, machinery and construction. The effect of cold galvanized square tube is far from that of hot galvanized square tube; How to distinguish hot galvanized square pipe from cold galvanized square pipe?Tadif,Cleaning solvent and emulsion can clean the surface of square tube to remove oil, grease, dust, agent and similar organic matter,GiovillanosGalvanized square pipe production line,GiovillanosDN100 hot dip galvanized pipe, but it can not remove rust, scale, welding, etc. on the surface of square tube, so it is only used as an auxiliary means in production.Hundreds of degrees Celsius, which can save energy.Due to the increase of square tube production, there are more and more fake and shoddy square tubes in the market. How to distinguish the fake and shoddy square tubes? Let me teach you some points to distinguish the fake and shoddy square tubes.
The other is designed with deformation angle, so the deformation angle & theta; It can accurately reflect the deformation degree of corners and edges. In the design process, considering the influence of dimensional accuracy and metal work hardening, the distribution of deformation angle is usually larger at the beginning and middle passes, and then gradually decreases. In the pass formed directly by arc intersection, the fillet part of the pipe blank cannot be filled with the pass, so the pass perimeter is different from that of the pipe blank. In order to ensure the dimensional accuracy, the fillet part of the pass needs to be corrected and calculated. Therefore, this method has higher design accuracy than other methods. However, due to the large amount of iterative calculation, this method is more suitable for pass design by computer. If you use a frame that deforms both horizontally and vertically, you can directly use the deformation angle & theta; Pass design.Square tube industry plays an important role in production and construction. Square pipe is a steel pipe made of a whole piece of metal without joints on the surface, which is called square pipe.Square tubes for petroleum cracking (gb-) are furnace tubes, heat exchangers and pipeline square tubes suitable for petroleum refineries.Quality recommendation,If there is only a single plane weld, the step-by-step back welding shall be adopted from the middle, that is, the arc of the section weld shall be terminated at the section arc.When sand blasting or manual mechanical derusting is used, due to the falling off of the oxide scale of the galvanized square pipe, the metal on the surface of the galvanized square pipe is directly exposed in the air. If a primer is not applied in time, the surface of the galvanized square pipe is easy to rust again affecting the adhesion of the paint film. I am engaged in all kinds of square tubes, square rectangular tubes, seamless square tubes, galvanized square tubes, galvanized tubes and other materials all year round. I operate in good faith. Welcome to call! As the paint is a time-effective material, the overstock of inventory is easy to expire. Therefore, the main indexes of the paint must be rechecked before use, and the paint can be used only when the results meet the standards.Stainless steel square tube for fluid transportation (gbt-) is a hot-rolled (extruded, expanded) and cold drawn (rolled) square tube made of stainless steel for fluid transportation.
Square pipe for diamond core drilling (gb-) is a square pipe for drill pipe, core rod and casing for diamond core drilling.Quality inspection report, which mainly has strict tolerance and roughness for the dimensions of inner hole and outer wall. Production process classification of large-diameter qb square tube large-diameter qb square tube is divided into hot-rolled seamless square tube, cold drawn seamless square tube, seamless square tube and qb square tube according to production process. Among them qb square tube is divided into: (a) by process & mdash& mdash; Arc welded square pipe, resistance welded square pipe (high frequency and low frequency), gas welded square pipe and furnace welded square pipe (b) are divided by weld & mdash& mdash; Material classification of straight seam welded square pipe and spiral welded square pipe large diameter qb square pipe: plain carbon steel square pipe and low alloy square pipe. Ordinary carbon steel is divided into Q Q q SS, # steel, # steel, etc; Low alloy steels are divided into q Mn, Q, St-, etc.The iron filings and burrs on the cutting section shall be completely removed with a file or appropriate tools to prevent the iron filings and burrs from scratching the rubber O-ring and other accessories when connecting another part.Normalized: A. pearlite steel; b. Bainitic steel; c. Martensitic steel; d. Austenitic steel.Giovillanos,The general delivery length of qb square pipe is mm-mm mostly mm and mm. Qb square tube is allowed to deliver short length and non fixed length products not less than mm, or in the form of interface tubeThe disadvantage of solid bending is that it has tensile thinning effect. The actual bending will produce tension at the bending point, and its characteristics are also different. Square tube has strict standards. There are many welding processes and advantages of square tube. Let me show you the welding process and advantages of lower tube.
