This phenomenon is affected by cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the plastic deformation non-uniformity and residual stress caused by thermal stress during cooling.

0Precautions for galvanized pipe storage

bSanta AnaCarburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.

Generally,Products Show what are the customer&#;s requirements and standards during acceptance? When the galvanized pipe is accepted,Miami18 # S I - beam SteelCe qui doit être vérifié avant l'opération d'inspection de l'équipement you can judge whether it is qualified from the appearance, or whether there are problems such as missing plating or bubbles on the outer wall of the whole square pipe. Only by solving these problems in time can it be judged as qualified and better used.

YNicoyaHow are seamless tubes made?

Jw Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.

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;

Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.

cGB No. I-beam is in height, in leg width and in waist thickness.

CIn view of the current market environment, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life,Products Show even in a field that seems to have little contact. It will be applied in many construction projects. At the same time, even in the depressed environment of the steel industry the application situation and utilization rate of this kind of pipe are very high.

VA complete range of productsIf the steel pipe is not welded well, that is, if it is not welded, the welding conditions of steel mesh skeleton composite pipe shall be provided.

jEMost of the original bridge decks lack a stable and solid base course with poor integrity. It is necessary to clear the original bridge deck, excavate part of the gravel cushion (if it is non gravel filler, replace it with gravel filler and tamp it), and then pave cement stabilized gravel base course on which reinforced concrete bridge deck is poured. The longitudinal reinforcement and transverse reinforcement of the reinforcement mesh of the bridge deck pavement form a network structure, so it has good bonding and anchorage with the concrete, and the load can be evenly dispersed,Products Show the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh.

From the situation of chiseling on site, the reinforcement mesh laid by the construction party is cm below the surface layer, which greatly exceeds the specification, and then the crack resistance of the reinforcement mesh can be reduced. Because of the increasing temperature, the cracking of surface layer is significant.

TrustworthyiThis phenomenon is affected by cooling rate, material composition and heat treatment process. The faster the cooling rate, the greater the plastic deformation non-uniformity and residual stress caused by thermal stress during cooling.

H Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely used

The allowable deviation of vertical installation of galvanized pipe is mm per meter, and the allowable deviation above m is no more than mm. The allowable deviation of horizontally installed pipes is mm per meter.

jSanta AnaThe multi-al combination of reinforcement mesh welding machine and reinforcement mesh row welding machine based on PLC basic control. At present, the full-automatic mesh welding machine has the characteristics of simple operation, high control precision and easy to master the process of high-speed continuous welding.

bDThe surface of cold galvanized layer is smooth, dense and uniform. It has good mechanical properties and corrosion resistance. The consumption of hot-dip galvanized coating is between % - %. The galvanizing process is complex, but the thickness of single-sided coating surface coating and double-sided coating is different, so the thin-walled pipe shall be galvanized. The zinc coating has strong protection and corrosion resistance.
