Sanshui RiverGalvanized 40 square pipeSolutions to product problems

For improper stamping direction, simulation software shall be used in the initial stage of design to ensure that the direction of stamping parts is analyzed, and when the high-quality requirements of components require the re development of molds, the direction shall be adjusted to seamless square tubes. The square tube manufacturer introduces the forming, bending and bending of square tubes. As the name suggests, the bending is compacted, and the inner and outer rollers are double with the inner and outer walls of tube billets during actual bending Compact towards the.Purpose of square tube the purpose of square tube includes construction, machinery, steel construction and other projects, shipbuilding, solar power generation support,Sanshui RiverWhere are galvanized square tubes, steel structure engineering, electric products ( pieces)Sanshui River,Mechanical polishing: after processing, the parts have good levelness, short gloss, medium and small products.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.Keratsini,Brinell hardness (HB), Rockwell hardness (HRC) and Vickers hardness (HV) are commonly used.Zinc layer thickness: there is a great difference between cold galvanized square pipe and hot galvanized square pipe in galvanizing process; Cold galvanized square pipes are prone to & ldquo; Electric burning & rdquo; The color of this part is gray and the zinc layer is thick. It is easy to form a current dead angle at the corner, resulting in an under current area. The zinc layer at this part is thin, and there is no zinc layer attached to the cold galvanized square pipe. The cold galvanized square pipe has no zinc lump and caking as a whole, but the overall zinc layer is thin, but the overall zinc layer is thick and there will be water marks and a few zinc tumors, and the thickness of the zinc layer on the inner and outer walls of the square tube is -mu; M above. The nature of QB square tube!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.

We all know very well. Therefore, the quality of square tubes will directly affect the development of the construction industry. What if we can make the service life of square tubes longer? Here, and use ingenious methods to prolong the service life of the square tube, so that the square tube can bring us greater help in life.Yield point of square tube (& sigma; s): the stress of metal material with yield phenomenon when the sample can continue to elongate without increasing (maintaining constant) the force during the tensile process, which is called the yield point. If the stress decreases the upper and lower yield points shall be distinguished. The unit of yield point is nmm (MPA).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.build,The second is to clean the surface of the opposite pipe. When cleaning the opposite pipe, the surface should be cleaned with solvent or emulsion. Square pipes of various specifications, square rectangular pipes, seamless square pipes, galvanized square pipes, galvanized pipes are supplied in time and cost-effective. They have become the preferred brand of many wire products. Welcome to buy! It is used to remove oil and dust. It is only suitable for removing grease and dust on the surface of square pipe, which can not remove rust and oxide scale. Therefore, it can only be used as an auxiliary means in production.Spraying (throwing) derusting spraying (throwing) derusting is that the high-power motor drives the spraying (throwing) blade to rotate at high speed, so that the steel sand, steel shot, iron wire section minerals and other abrasives can be sprayed (thrown) on the surface of the square tube under the action of centrifugal force, which can not only completely remove rust, oxides and dirt, but also the square tube under the violent impact and force of abrasives, It can also achieve the required uniform roughness.C. special performance steel: (a) stainless and acid resistant steel; (b) Heat resistant steel; (c) Electric heating alloy steel; (d) Electrical steel; (e) High manganese wear resistant steel.

It should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter, and R and R can be equal or different.index,Mechanical engineering, power plants, agricultural and chemical machinery, automobile chassis, airports, boiler construction, highway railings, housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, heavy transportation machinery and other welded structural parts with high load,Sanshui RiverWhere does galvanized square tube sell, 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.When cutting, please fix it with square tubes such as vise, and then cut it after it is fixed.The characteristics of square pipe are as follows: the production process of square pipe is simple, the production efficiency is high, the cost is low and the development is fast. The strength of spiral square pipe is generally higher than that of straight seam square pipe. It can produce square pipe with larger pipe diameter with narrow blank, and square pipe with different pipe diameter with blank of the same width. However, compared with straight seam pipe of the same length, the weld length is increased by ~, which will be oriented to the whole country for a long time Individuals and enterprises provide all kinds of square tubes, square rectangular tubes, galvanized square tubes, galvanized tubes, on-site settlement, honest operation local offices, long-term cooperation, and low production speed. Therefore, most of the smaller square tubes adopt straight seam welding, and most of the large-diameter square tubes adopt spiral welding.Sanshui River,Functional index analysis of qb square tube - mechanical function of plastic square tube. Solid bending,Sanshui River80 galvanized rectangular pipe, as the name suggests, is to compact the bending. During real bending, the inner and outer rollers and the inner and outer walls of the pipe blank are compacted in both directions.Stage ( & mdash; )It should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter, and R and R can be equal or different.
