Application scope of alloy pipe Small longitudinal crackEl pugrusoWhen excavating a tunnel in a stratum where the rock is not hard and complete, it is generally necessary to excavate a diversion pit (also known as pilot hole) and set temporary support. Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.Faridabad,I-beam, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane so its application range is very limited. I-beams are widely used in buildings and other metal structures.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.Application characteristics of I-beam:

Dry processing technology: after passivation treatment,El pugrusoHow much is the price of galvanized pipe, parts shall be dried with air compression or hot gas, and the pipeline support shall be prefabricated according to the site conditions. Hang the wire from the th floor down and fix the support.Requirements of alloy tubes for low and medium pressure boilersWelcome calls , most of the flat steel on the market are finished steel, which can be used ready-made for components,El pugrusoWhat is the outer diameter of welded pipe DN50,El pugrusoHow much is the wholesale price of welded pipe, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate. 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, 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.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.

→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.Potential development,The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃ Pickling: if the material cannot be removed after cleaning, pickling will be selected. Pickling of galvanized pipe is divided into chemical and electrolytic. How to prevent white rust of galvanized seamless steel pipe? It has a certain anti-corrosion effect on the pipeline.What are the requirements for alloy pipe construction accessoriesEl pugruso,Ways to obtain surface compressive stress characteristics of alloy tubesBecause all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.Application characteristics of I-beam
