PerraGalvanized stainless steel square pipeWhat is the application concept
Forging square tube: a kind of pressure processing in which the reciprocating impact force of the forging hammer or the pressure of the press changes the blank into the shape and size we need. It is generally divided into forging and die forging. It is often used to produce large-scale materials and materials with large square tube size.Fake and shoddy square tubes are easy to scratch, because the equipment of fake and shoddy material manufacturers is simple and easy to produce burrs and scratch the surface of square tubes. Deep scratches reduce the strength of square tubes.Perra,Low alloy steel is divided into q Mn, Q, St-, etc.Reinforcing phases such as reinforcing particles, short fibers and whiskers can be added to the solder to form composites.Talagante,Purpose of square tube the purpose of square tube includes construction, machinery, steel construction and other projects, shipbuilding, solar power generation support, steel structure engineering, electric products ( pieces)Large diameter qb square tube production standard classification square tube is divided according to production standard: national standard square tube, Japanese standard square tube, British standard square tube, American standard square tube, European standard square tube and non-standard square tube.Mechanical engineering, power plants, agricultural and chemical machinery glass curtain walls, automobile chassis, airports, highway railings, housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, heavy transportation machinery and other welded structural parts with high load, etc. Process classification: according to the production process, square tubes are divided into hot-rolled seamless square tubes, cold drawn seamless square tubes, seamless square tubes and qb square tubes.
Generally speaking, square pipe welding has a process: ignition, pressurization and thermal insulation.Evaluation of test results after the test, the bending deformation of the sample is qualified if there is no crack or crack. The squash test rating square pipe produced by square pipe factory has been widely used. Of course, the current situation is inseparable from the strict control of square pipe factory in technology, which makes the development of steel pipe make a lot of contributions. Let's look at the specific purpose of the lower tube.Engaged in square tube, square rectangular tube, seamless square tube, galvanized square tube, galvanized tube, old brand, price advantage and quality guarantee! However, the Demander shall cut off the interface pipe when using it. The weight of short length and non fixed length products shall not exceed % of the total delivery. For qb square pipe with theoretical weight greater than kgm, it shall not exceed % of the total delivery. The bending degree of qb square pipe shall not be greater than mm per meter, and the total bending degree shall not be greater than .% of the total length. Galvanized qb square pipe for low-pressure fluid transmission, with standard number of gbt-. Representative materials: QA, qbqb, etc. It is mainly used for conveying water, gas, air, oil and heating hot water or steam, and its purpose is limited to general low pressure fluid.Product survey,Square tube has a wide range of application fields. Its main field is the construction industry, which promotes the development of economic construction. Because the production process of square tube hole is different, the production design of square tube hole is also different. Next,PerraGalvanized composite steel pipe, I will introduce in detail the types of tube hole design below.C. electric furnace steel: (a) electric arc furnace steel; (b) Electroslag furnace steel; (c) Induction furnace steel; (d) Vacuum consumable furnace steel; (e) Electron beam furnace steel.If the test results of square tubes fail to meet the provisions of product standards,PerraSpecification of galvanized pipe, the unqualified ones shall be selected and double the number of samples shall be taken from the same batch of square tubes for re inspection of unqualified items. If the re inspection results (including any index required by the test of the project) are unqualified, the batch of square tubes shall not be delivered. If the following inspection items fail to pass the preliminary inspection, re inspection is not allowed: A. There are white spots in the low magnification; b. Microscopic.
Square tube nonferrous metals, also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, tin, lead, zinc aluminum, brass, bronze, aluminum alloy and bearing alloy. In addition, chromium, nickel, molybdenum, cobalt square tube, vanadium, tungsten, 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, including radioactive square tubes.Executive standard,The difference between square pipe and seamless steel pipe the main feature of seamless steel pipe is no welding joint and can withstand large pressure. The product can be very rough as cast or cold drawn parts.Hardness test is to use a hard indenter to slowly the sample surface according to the specified conditions, and then test the indentation depth or size, so as to determine the hardness of the material. Hardness test is simple, rapid and easy to implement in material mechanical property test. Hardness test is non-linear, which is of great practical significance.The square tube is divided into a. boiling steel according to the degree of deoxidation and pouring; b. Semi killed steel; c. Killed steel; d. Special killed steel. The deformation of qb square tube is mainly caused by the shrinkage force of the weld greater than the strength of the base metal.PerraCarbon steel classified by chemical composition: square tube A. low carbon steel (C & le; .%); b. Medium carbon steel (C & le; . ~ .%); c. High carbon steel (C & le; .%).Functional index analysis of qb square tube - angular plasticity refers to the power of plastic deformation (permanent deformation) without destruction of qb square tube data under load.Mechanical engineering, power plants, agricultural and chemical machinery glass curtain walls, automobile chassis, airports, boiler construction, highway railings, housing construction, pressure vessels, oil storage tanks, power station equipment, heavy transportation machinery and other welded structural parts with high load,PerraGalvanized square steel pipe, etc. Process classification: according to the production process, square tubes are divided into hot-rolled seamless square tubes cold drawn seamless square tubes, seamless square tubes and qb square tubes.
