Emulsified asphalt emulsion is also easy to use on the mobile slurry seal paver. It is necessary to mix on the machine and use additives for chemical control for maintenance.Difference and application description between H-beam and I-beamVilla Kula

I-beamI-beam is widely usedPetapa,Defects of alloy pipe and solutions: 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,PetapaCold drawn welded pipe manufacturer, and the waist is parallel to the roll axis.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.

Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation. Fabrication and installation of pipe support:I-beam is mainly divided into ordinary I-beam, 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,PetapaHow much is the I-beam rental per ton, 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.build,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. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.

At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.discount,According to the theory of steel structure,PetapaWhat is the price of 50 seamless pipe, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down. It has iron zinc alloy layer and compact combination, the axial movement is small, and the working slope is not required,Petapa,Defects of alloy pipe and solutions: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.Alloy pipe is a spiral seam seamless steel pipe which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.
