According to the quality of square tubes, we will conduct progressive research on them, hoping to develop better square tubes. No matter what environment, we will make square tubes suitable for use. Then, square tubes are mostly used for transportation, so the adhesion resistance makes square tubes not stick during transportation.

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, 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.

After time, the workpiece forms an oxide film with a fixed thickness and presents various colors. Chemical oxidation method is to form various film colors in a specific solution at temperature and time; Because of the law & rdquo; More, but to maintain the color of the product, the reference electrode must be used. Electrochemical method is to form the color of chloride film with fixed thickness in specific electrolyte at temperature, voltage and time. This process is mature and widely used. Ion implantation method is to vaporize ions in vacuum and deposit them on the surface of q355b square tube, such as watch case on the market. The golden color of watch strap adopts this process technology, which is suitable for mass production. The process of gas phase cracking is more complex and less used in industry. Square tube has long been widely used in mechanical industry. When the square pipe is cut automatically, when the square pipe is hoisted to the gas cutting platform, the distance difference between the two ends of one side of the pipe and the guide rail shall be adjusted within 5mm. During semi-automatic cutting, the guide rail shall be placed on the plane of the cut pipe, and then the cutting machine shall be placed on the guide rail gently.

After cold drawing and aging treatment, the yield point is improved the tensile ultimate strength is also increased, and the plasticity continues to decrease. Due to the reduction of internal stress during aging, the modulus can be basically restored. According to this principle, cold drawing or cold drawing of reinforcement or low carbon steel wire rod is often carried out on site or prefabricated component factory, so as to improve yield strength and save steel.

After the sample is flattened to the specified flattening distance h, remove the load and remove the sample.

Welcome calls .At the same time, hanging heating shall be carried out during heating to reduce quenching deformation. For high-precision guide rail, gas nitriding or ion nitriding shall be carried out to reduce deformation; Square tubes have outstanding performance in all aspects of performance. We will also test them in this regard when making square tubes more durable. What outstanding performance do square tubes have in mechanical properties? Next, I'll introduce it to you.

In short, the square tube production process includes these processes: tube blank & mdash& mdash; Cut off & mdash& mdash; Heating & mdash& mdash; Perforation & mdash& mdash; Pipe rolling & mdash& mdash; Sizing (reducing) & mdash& mdash; Straightening & mdash& mdash; Cut head and tail & mdash& mdash; Inspection & mdash& mdash; Packaging & mdash& mdash; Warehousing.

Elongation after square tube breaking (& sigma;): in the tensile test, the percentage of the length increased by the gauge length of the sample after breaking and the length of the original gauge length is called elongation. In & sigma; Expressed in%.

Square tubes shall be stored with supports, products and tens of millions of products for you to choose. Professional square tubes, square rectangular tubes, galvanized square tubes and galvanized tubes are safe and secure. They shall be at a certain distance from the ground to ensure the ventilation of square tubes.

Quality recommendation.Square tubes are more and more widely used in practice. Different types of square tubes have different characteristics, and the performance of each type of square tube is also different. Choose according to its performance in different aspects, so as to improve its work efficiency. Next, let's introduce what should be paid attention to when heating the lower tube.

Q355b square tube, q355b square tube, q355b square tube, Q345B square tube, Q345B square tube and hot-rolled right angle square tube are of good quality and excellent quality. We have become a supplier of many enterprises. Q355b square tube and I-beam are two products with different shapes. Under the condition of the same material, the bearing capacity of steel is the same, but their uses are very different. The shape is different. Q355b square tube is a cuboid, and I-beam is in I-shape. The purpose is different. I-beam can be used as span and support. Square pipe is a little worse than span. It is no problem to do support. However, the specific selection of steel depends on the requirements of the project. Square tube practical application square tube for structure (gbt8162-199) is a square tube for general structure and mechanical structure.

In terms of hot working, repeated upsetting and multi-directional rolling of ingot can not only reduce the level of carbide segregation in square tube,Kampong Baharu Nilai VillageGalvanized plastic lined pipe, but also improve the anisotropy of steel.

Kampong Baharu Nilai Village.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.

After the square tube is cut into a single square tube, the head and root of each batch of square tube shall be subject to strict first inspection. The mechanical properties, chemical composition, fusion condition, many new substances have taken place, and the original characteristics have changed. However, in order to maintain the original relevant characteristics, anti-oxidation treatment is required. The direct reason is to prevent the square tube from reacting with the oxygen in the air, which is the way to isolate the oxygen in the air. Today, this article makes a relatively standardized treatment on the relevant steps to prevent oxidation of square tubes: the key depends on what kind of antirust paint you use. 1. If you use epoxy zinc rich or iron rich antirust paint, you can directly spray fluorocarbon paint on it; 2 if alkyd antirust or red lead is used, it shall be cleaned with paint remover and sprayed with epoxy zinc rich or iron rich antirust paint again before fluorocarbon paint can be sprayed.
