Today, with the development of the world, all fields are coming rapidly, which makes the demand for square tube higher and higher, and the requirements of customers for square tube higher and higher. Now we are studying a new square tube. The following mainly introduces the performance of square tube in tensile strength.
Compared with other traditional pipes, high strength good resistance, can withstand high internal pressure, sensitive application, sand blasting, it can not be seen that they are welded elbows.
Effective treatment of square tube coating & ldquo; Surface defense line & rdquo; Surface technology and measures square tube coating is used as the back course & ldquo; Surface defense line & rdquo; The surface treatment technologies and measures can be carried out on the basis of other surface treatment technologies or processes. Here's the & ldquo; Surface treatment before coating & rdquo; It refers to all treatment measures for preparation for coating or joint protection with coating. Therefore, the surface treatment before coating is also called coating surface pretreatment.
.Before gas cutting, remove the dirt and grease on the steel surface, and leave a certain space below to facilitate the blowing out of slag. During gas cutting, the edge of the cut will melt, and if it is too far away, the cutting will be interrupted easily due to insufficient heat.
When the square tube is processed, it needs to be properly polished to ensure durability, including mechanical polishing, chemical polishing and electrochemical polishing.
When cutting the square tube there will be deformation, uneven incision and crack of the incision. What should we pay attention to when cutting the square tube and how to operate it? Today, I will introduce some problems that should be paid attention to when cutting the square tube. If the correct operation will make the square tube cutting work very smooth, please use a rag or cloth to clean the oil on the surface of the square tube Sundries or soil shall be completely clean.
The flattening speed of the sample can be 20 ~ 50mmin.
Hardness hardness is a pointer to measure the hardness and softness of metal materials. At present, the hardness method is commonly used to measure the hardness in production. It uses the indenter with fixed geometry to measure the hardness value of the metal material surface tested under fixed load according to the degree of hardness.
After perforation the round tube blank is successively rolled by cross rolling, continuous rolling or rolling. Take off the pipe after sizing. The conical drill bit of the sizing machine rotates into the steel embryo at high speed to form a steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the sizing machine bit. After sizing, the steel pipe enters the cooling tower for water spray cooling. After cooling, the steel pipe will be straightened. After straightening the steel pipe
Create brilliance.With the development of economy, there are a lot of demands for project construction, which leads to the continuous increase of square pipe. The of square pipe is more complex. Great efforts should be made in the selection of raw materials structured treatment and so on.
At present, researchers at home and abroad have carried out experimental discussion on the anti adhesion of square tube surface. So far, there is still a lack of research on surface adhesion, there is no systematic and perfect theory to guide the preparation of anti adhesion inner surface of pipeline, and there is a lack of operable and low-cost inner surface preparation technology of square pipe. In terms of solid surface adhesion mechanism, based on the solid-liquid interface adhesion work theory and smooth solid surface model, this paper analyzes the spreading process on machined rough surface, studies the dynamic movement characteristics of solid-liquid vapor phase line, directly analyzes the adhesion process, and establishes a line spreading model based on small system energy, It provides theoretical guidance for the preparation of anti adhesion surface of pipeline.
Requirements for samples samples can be taken from metal pipes with qualified appearance. Generally, sawing is adopted.
Application of square tube products: for mechanical equipment, solar energy equipment, steel structure, automobile parts, bridge ground pile, guardrail and ship internal structure.
Installation requirements.The square tube shall be painted correctly. Professional square tube, square rectangular tube, seamless square tube, galvanized square tube and galvanized square tube have stable, safe and reliable performance and can be maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. Otherwise, the square tube will be corroded. The correct paint shall also be selected during painting so as to ensure that the square tube can be used more firmly, So as to ensure that the square tube will be better and better in future use. The square tube is widely used in the soul. Each kind of square tube has different functions for the other tube. We choose the right way and different square tubes, which can increase the performance of the square tube and be applied to different fields. Let me briefly introduce the lower tube.
Square pipe for diamond core drilling (gb3423-8) is a square pipe for drill pipe, core rod and casing for diamond core drilling.
After aluminum deoxidation in molten steel, & omega; When (ALS) is 0.015% ~ 0.025%, calcium treatment can achieve better effect on the denaturation of Al203.
Mercedes.The square tube shall be painted correctly. Professional square tube, square rectangular tube, seamless square tube, galvanized square tube and galvanized square tube have stable, safe and reliable performance and can be maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. Otherwise, the square tube will be corroded. The correct paint shall also be selected during painting, so as to ensure that the square tube can be used more firmly, So as to ensure that the square tube will be better and better in future use.

We choose the right way and different square tubes, which can increase the performance of the square tube and be applied to different fields. Let me briefly introduce the lower tube.
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.
Reach or even exceed the level of resistance welding cold formed square pipe. The size of R angle is generally between 2-3 times of the wall thickness. R angle square pipe of the size required by customers can also be produced according to customers' needs; Square pipe is a kind of long steel with hollow section and no joints around. It is a square pipe formed by four sides of seamless pipe mold. Square pipe has hollow section, professional square pipe, square rectangular pipe, seamless square pipe, galvanized square pipe, galvanized square pipe, strict inspection and quality assurance. The preferential activity is in progress. Welcome to consult. A large number of pipes are used for conveying fluid. They are mainly used in conveying, hydraulic support and mechanical structure, Medium and low pressure, high pressure boiler tubes, heat exchange tubes, gas, oil and other industries. It is stronger than welded and will not crack.
