Due to the impact of poor visual . Only through the application of mesh and the overall stiffness can we see the potential of demand. The application of steel data is a high one, such as the reuse rate of mesh and reinforcement installed in the current mesh production company and the treatment of corrosion. The design strength value of circular reinforcement and the design strength value of welded reinforcement mesh. According to the equal strength substitution principle and considering comprehensive factors, the use of steel welded mesh plate can save the use of steel bars in the steel welded mesh plate factory. And the reinforcement mesh needs to be processed after it is shipped to the site, so there is no wear.

2Installing the pipe structure means the complexity of some elements.

yCalgaryI-beam is widely used

As long as the pipe material is high-strength alloy steel, including alloy steel pipes with temperature resistance, pressure resistance,Products Show wear resistance and low temperature resistance,كايا40Cr سبيكة أنابيبكيف تختار واحدة جيدة the welding process shall be focused on preventing the tendency of martensite structure and cracks due to welding high-temperature operation. The general process requirements are that the welding rod shall be selected and baked as required and sent to the welder for use. The oil and water shall be removed before welding on both sides of the weld Rust and sundries shall be removed and cleaned. The welding line energy shall be as small as possible to minimize the swing during the welding process. The arrangement of the last weld shall have annealing effect on the heat affected zone as far as possible. Slow cooling after welding, cover with asbestos cloth, etc.

NVienna Whether the mesh size and wire diameter of electric welding mesh meet the standards

Mt East West derusting: if the galvanized pipe surface is rusty, the manufacturer will choose East West derusting and polish it with a steel wire brush

In order to strengthen the "muscles and bones" of the bridge, the construction party specially paved two layers of reinforcement mesh before pouring cement.


When the mesh reinforcement on both sides of the beam is different, the reinforcement on both sides extends into the beam, and the reinforcement anchorage length is required.

lPassivation treatment operation of alloy pipe

AGalvanized; hot-rolling;

JCustomer firstGenerally speaking, and it is prone to uneven wall thickness, some pits or black spots are easy to appear on the inner and outer surfaces. In addition to these,Products Show the seamless pipe manufacturer needs to carry out off-line processing for its detection, and its strength is relatively high, the pressure is high, and its advantages can be reflected in the material of mechanical structure. Seamless pipe can be divided into hot extrusion, hot rolling and cold rolling stainless steel pipe according to its rolling method. In addition, different elements can also be used for classification. The inner and outer surfaces of seamless pipes shall be free from chaps, folds, cracks, cracks, scabs,Products Show delaminations and other defects. If these defects are to be removed, it is necessary to use machining. The removed seamless pipes shall not have negative deviation after the inner diameter is followed If other minor surface defects with negative deviation cannot be removed,كايا40Cr سبيكة أنابيبكيف تختار واحدة جيدة it is not a qualified product. The allowable depth diameter of straight path of seamless pipe is less than or equal to mm, and its depth shall not be greater than . mm.

tY General carbon steel wire sleeve (GB / t- is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings and installation of machinery and equipment.

Generally, what are the customer&#;s requirements and standards during acceptance? When the galvanized pipe is accepted, you can judge whether it is qualified from the appearance, generally : I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, 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.

Material requirements

eCalgaryGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd also known as steel cold-formed profile. It is a section steel with square section shape and size, which is made of Q hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding. In addition to wall thickness thickening, the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe. Good comprehensive mechanical properties, weldability, cold and hot workability and corrosion resistance, and good low temperature toughness.

oIThe second is the control of welding materials to ensure that the welding materials purchased are from formal channels, with quality assurance certificate and certificate, which meet the process requirements; The recovery of welding rod head shall be strictly controlled to ensure the flow direction and dosage; Welding materials shall be baked in strict accordance with the process, and the amount of one-time distribution shall not exceed half a day.

Stretch punching by steel plate equipment; The main purpose is to be used in the structure of scaffold.
