because the section size is relatively high and narrow the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Desanpalados Fabrication and installation of pipe support: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, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, 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 it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Batangafo,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, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.

I-beam is widely used Main machines and toolsGenerally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Industry management,When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold,DesanpaladosAlloy pipe gh648, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.Key technical characteristics of alloy pipe

Introduction to product knowledge of alloy pipe:assets,Alloy pipes can be used for heating (cooling) projects.Galvanized pipe can be seen from its name. It is a square pipe type. Many materials can form galvanized pipe body. It is used for what purpose and where. Most galvanized pipes are steel pipes. After unpacking, crimping and welding, they form round pipes, which are rolled into square pipes, and then cut into the required length. Generally, there are galvanized pipes in each package. In terms of spot, most of them are in large specifications, ranging from * * .- to * * - Galvanized pipes are divided into structural galvanized pipes, decorative galvanized pipes,DesanpaladosHow much is a 20 cm I-beam, architectural galvanized pipes, mechanical galvanized pipes, etc.X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Desanpalados,Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.
