Platform reinforcement mesh is a widely used reinforcement mesh product， such as industrial maintenance platform， berm， etc. this kind of reinforcement mesh is widely used in industry， electric power， coal mine and other fields，Products Show and has the strongest resistance to surface impact，SabaniraAlloy pipe GH3044Low density of polymer materials especially the reinforcement mesh with a cross bar spacing of mm has a strong ability to resist lateral impact.
8In order to strengthen the "muscles and bones" of the bridge， the construction party specially paved two layers of reinforcement mesh before pouring cement.
mAtletico Granadilla I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:
Galvanized pipe has excellent corrosion resistance
MKaguaStretch punching by steel plate equipment; The main purpose is to be used in the structure of scaffold.
XmCompared with manual binding， welded steel mesh can reduce the occurrence of cracks by more than %. The use of reinforcement mesh can make the project construction faster. As long as the reinforcement mesh is laid as required， the concrete can be poured， eliminating the links of reinforcement on-site cutting， placing one by one and binding. It can save % - % of working hours， greatly accelerate the construction progress and shorten the construction cycle.
According to the section shape， the steel pipe is divided into:
Seismic and cracking performance the longitudinal and transverse bars of the welded reinforcement mesh form a network structure， so it has good bonding and anchorage with the concrete，Products Show and the load can be evenly distributed， which obviously shows the seismic cracking performance of the reinforced concrete structure. According to the actual test， the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. It greatly reduces the unnecessary cost generated manually in the construction and shortens the construction period. The use of reinforcement mesh is simple and convenient， and the reinforcement mesh is convenient for transportation.
zThe working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction， so that the width is compressed to achieve the expected parameters， and the compression amount is adjustable; Straighten the width with staggered straightening wheels.
D Manganese: it can improve the strength of steel， weaken and eliminate the adverse effects of sulfur， and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties
EEquipment maintenance Ditch cover plate (ditch cover plate) is widely used in municipal roads， garden facilities， residential quarters，Products Show schools， stadium pipes and other places.
vAIt is divided into circular welded pipe and special-shaped (square，SabaniraAlloy pipe GH3044Low density of polymer materials flat etc.) welded pipe.
What is theof defect detection of seamless pipe? Magnetic particle testing or penetrant testing of seamless pipes can effectively find surface defects such as cracks， folds， double skin， hair lines， pinholes and so on. Because of its high detection sensitivity magnetic particle detection method should be preferred for ferromagnetic materials. For non ferromagnetic materials， such as stainless steel seamless pipe， penetrant testing method is adopted.
Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility， so it is flexible.
indexv Simple section steel pipe -- circular steel pipe，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd square steel pipe， oval steel pipe， triangular steel pipe， hexagonal steel pipe， rhombic steel pipe， octagonal steel pipe， semi-circular steel pipe， others.
ZH-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.
Keep the combustion supporting gas and use it reasonably to avoid fracture of the welding interface. Problems in the welding of steel wire mesh skeleton composite pipe are common， it is generally necessary to excavate a diversion pit (also known as pilot hole) and set temporary support.
dOLongitudinal welded pipe has the advantages of simple production and processing technology， high production efficiency， low cost and rapid development trend. The compressive strength of spiral welded pipe is generally higher than that of straight welded pipe. Narrow blank can be used to produce welded pipe with large pipe diameter， and blank with the same total width can also be used to produce welded pipe with different pipe diameter. However， compared with the straight seam pipe with the same length， and the production rate is low.
Blanking shall be carried out according to the design and site， and then the groove shall be made with a grinder with a groove angle of ° ~ °. Fix the processed pipe on the support， and then weld.
