→ under the same section load,HalifaxHow much is 80 welded pipe per meter, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningHalifax,Installing the pipe structure means the complexity of some elements.The 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,HalifaxAlloy pipe GH3030, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.Santa Lucia,Some applications of I-beam:So why is the alloy pipe easy to rust after being pickled and passivated by the software?So why is the alloy pipe easy to rust after being pickled and passivated by the software?

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, the automatic control system will be upgraded.However, compared with plastics, these pipes, like other metals, remain stable and will not be affected by high temperature.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.A complete range of products,Key technical characteristics of alloy pipeH-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.Heating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)

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,Halifax50 galvanized pipe is a few inches of pipe, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.Word of mouth recommendation,Alloy pipes can be used for heating (cooling) projects. Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base, hot-plated parts can be formed by cold stamping, rolling, wire drawing, bending and so on without damaging the coating;After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.Halifax, 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.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %
