Palma Soriano10# steel seamless pipeSeveral main reasons for hindrance

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.Whether I-section steel is ordinary or light, 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.Palma Soriano, Simple section steel pipe -- circular steel pipe, square steel pipe, oval steel pipe, triangular steel pipe, hexagonal steel pipe, rhombic steel pipe, octagonal steel pipe, semi-circular steel pipe, others.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementIlobu,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.I-beam has wide flange, thin web many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Some applications of I-beam:

I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones, rubber, polyurethane, it has irreplaceable comprehensive excellent properties.Defect detection of seamless pipe The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Quality risk,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.→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.

I-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.build,Palma SorianoWhat is the outer diameter of DN20 welded pipe,The key purpose of grinding and polishing alloy pipe is to moisten the surface, and the preparation of construction equipment and engineering machinery.After determining the reasonable pickling agent and polishing solution the inspection and acceptance of the lower layer of the pavement, 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,Palma SorianoHow much is DN65 galvanized pipe, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.Palma Soriano, Small longitudinal crackWelded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.Application scope of alloy pipe
