HoragosWhere is 40CrMo seamless pipe,

→ the two surfaces of the flange are parallel to each other, making it easy to connect,HoragosWhat is the outer diameter of DN20 welded pipe, process and install.Key technical characteristics of alloy pipe:Horagos,Longitudinal welded pipe has the advantages of simple production and processing technology, high production efficiency, and blank with the same total width can also be used to produce welded pipe with different pipe diameter. However, compared with the straight seam pipe with the same length, the welding length is increased by ~ , and the production rate is low.What should we pay attention to in the production of alloy pipeKhujaobod, Mixed pass system. According to the characteristics of rolling mills and products,HoragosASTM A106B seamless pipe, mixed pass system is often adopted that is, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc.Pass designb. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.

Determined by the shape, the section modulus, pressure load and eccentric load. Compared with ordinary I-beam it shows its superior performance in bearing bending moment, it can greatly improve the bearing capacity and save metal by % ~ %.Wire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin, which is mostly used after coating or galvanizing, and cold bending test is required.Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.Create brilliance,→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.

Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Product survey,Alloy pipes can be used for heating (cooling) projects. Pipe installation:H-shaped steel groove is deep and thick, and can withstand forces in two directions.Horagos,After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties weldability and structural size.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, 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.
