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

We all know very well. Therefore, we also need to ask the personnel of the square tube manufacturer for instructions,AquintelDimension table of galvanized round pipe, 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.Section shape classification square tubes are classified according to section shape: simple section square tubes & mdash& mdash; Square tube, rectangular tube and complex section square tube & mdash& mdash; Surface treatment classification of flower shaped square pipe, open square pipe, corrugated square pipe and special-shaped square pipe square pipe is divided into hot-dip galvanized square pipe, electro galvanized square pipe, oil coated square pipe and pickling square pipe according to surface treatment. Square pipe is classified according to purpose & mdash& mdash; Square tubes for decoration, machine tools and equipment, machinery industry, chemical industry steel structure, shipbuilding, automobile, steel beam and column and special purpose are classified by wall thickness & mdash& mdash; Super square tube, square tube and thin-walled square tube plasticity refers to the ability of metal materials to produce plastic deformation (deformation) without deformation under load.Aquintel,Performance index analysis of square tube - plasticity refers to the ability of metal materials to produce plastic deformation without deformation under load.Fatigue strength, plasticity and hardness discussed above are indicators of the mechanical properties of metals under static load. In fact, many machine parts work under cyclic load, under which fatigue will occur.Maceio,Functional index analysis of qb square tube - mechanical function of plastic square tube. Solid bending, 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.Normalized: A. pearlite steel; b. Bainitic steel; c. Martensitic steel; d. Austenitic steel.If the test results of square tubes fail to meet the provisions of product standards, 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.

Brinell hardness (HB), Rockwell hardness (HRC) and Vickers hardness (HV) are commonly used.(& sigma; Su): the large stress before the yield stress of the sample decreases for the first time; Lower yield point (& sigma; SL): the small stress in the yield stage when the initial instantaneous effect is not considered. The calculation formula of yield point is as follows: where: FS -- yield force (constant) in the tensile process of the sample n (Newton) so -- original cross-sectional area of the sample, mm. Elongation after fracture (& sigma;) in the tensile test, the percentage of the length increased by the gauge length of the sample after breaking to the original gauge length is called elongation.Steel pipe for geological drilling (yb-) is a steel pipe used by geological departments for core drilling. It can be divided into drill pipe, drill collar, core pipe, casing, sedimentation pipe, etc.Which one is better,Fatigue strength, plasticity and hardness discussed above are indicators of the mechanical properties of metals under static load. In fact, under which fatigue will occur.Improve the positioning and pre bending steps, to ensure that the web hunting problem does not occur when pressing parts. Change the shape of the surface pressure of the material to ensure the quality of the parts and avoid the non movement of the surface shape of the roll gap, resulting in uneven walking feeding.The reason why it is divided into two types is that chemical cleaning can only clean the surface very thoroughly, and it is difficult to achieve the desired results in some fine cracks.

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.Price,The pressurization size and time are the key to the success or failure of welding. If the square tube synthetic material is not pressurized, a large number of pores will be caused due to the pores of the material itself and the gas generated in the reaction. It is not allowed to leave the reactants in the weld, so it must be densified,AquintelHot dip galvanized steel pipe, usually pressurized during the reaction.The qb square tube rolled from the strip steel through process treatment is generally to unpack, flatten, curl and weld the strip steel to form a round tube, then roll the round tube into a square tube, and then cut it to the required length. Nowadays, and the total bending degree shall not be greater than the actual bending of the total length. As the name suggests, the bending is compacted,AquintelGalvanized square pipe machine, and the internal and external rollers and the internal and external walls of the tube blank are compacted in both directions during the actual bending.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.Aquintel,The inspection items, sampling quantity, sampling position and test of square tube shall be in accordance with the provisions of corresponding product standards. With the consent of the demander, hot-rolled square tubes can be sampled in batches according to the rolled root array.Pull square tube: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, 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, It can also achieve the required uniform roughness.

but also the square tube under the violent impact and force of abrasives
