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.The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Dragar , Stair step plate (stair step plate) is a kind of stair used for platform with steel bar mesh. According to the installation method, it generally has two types: welding fixation and bolt (composition: head and screw). It is directly welded to the keel and does not need the side plate with step plate. It is relatively economical and durable but it is not easy to disassemble, Thickened side plates are required on both sides of the bolted tread plate, and holes are drilled on the side plates.Function of I-beam: where is I-beam mainly used?Le Havre,The key purpose of grinding and polishing alloy pipe is to moisten the surface, and the relevant limit accuracy or appearance change is not easy to change.What is nitriding of alloy pipeThe utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body,Dragar Where do you sell welded pipes, and more passes can be matched under the condition of a certain length of the roll body.

What are the uses of I-beam? Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming, double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure, wharf, bridge, etc.In order to make the steel pipe workpiece have the required mechanical, in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, aluminum, copper, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.Customer first,The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No. and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %,Dragar High strength plastic alloy pipe, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio) the solution temperature is ~ ℃, and the solution time is min.

However, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.technical service, Small longitudinal crack Ditch cover plate (ditch cover plate) is widely used in municipal roads, garden facilities, residential quarters, schools, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Dragar ,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 :,Dragar How much is a steel hoop bending machine, 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.Application scope of alloy pipe Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time
