IjidoPrecision cold drawn seamless pipe manufacturerThe main development trend

After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry. Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small,IjidoWill reinforced concrete rise or fall in 2021, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded.Ijido, including corrosion. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Wagar,I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.C-section steel has uniform zinc layer, smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.As shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different,IjidoDirect sales of welded pipe manufacturers, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.

The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.The electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics, after deducting the steel consumption increased by unit lapping, it can also save about % of the steel. After it is transported to the site according to the construction degree of the project, it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site, which saves the site and increases the management level of the site. At the same time, it can also solve the problems of noise pollution caused by straightening reinforcement.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.install,Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption not occupy the natural environment, prevent actual operation and maintenance but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole,Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing, boronizing, siliconizing and so on are commonly used in production.The fourth is the welding process method to ensure the strict implementation of the special operation method of galvanized pipe. The welding process includes pre welding groove inspection, control of welding process parameters and operation methods, post welding appearance quality inspection, and post welding nondestructive testing if necessary. Control the welding level and the amount of welding materials at each crossing.I-beam also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Ijido, Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example,IjidoWholesale of galvanized pipe manufacturers, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, there are many things that must be paid special attention to. Let&#;s take you to know:→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.
