When the end span plate is connected with the concrete beam for structural reinforcement, the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small, the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall, the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement), garden facilities, residential quarters,Products Show stadium pipes and other places.

kLevisWhen selecting I-beam in structural design,رانكيلC276 سلس الأنابيب المصنعةالعوامل المؤثرة على تغيرات الأسعار reasonable I-beam shall be selected according to its mechanical properties, chemical properties, with chemical composition content of C carbon .%, Si silicon .% Mn manganese %, s sulfur ≤ .%, P phosphorus ≤ .%, yield strength of mpa and tensile strength of MPa. High temperature continuous casting and rolling or ingot heating rolling. Soft,.

RKuvisina China is a big steel country.

Qi In order to ensure the welding quality of pipes high ductility, welders shall be trained,Products Show tested and qualified. In addition to the basic theory, the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large, and the current cannot be adjusted in the middle of one formation). In the process, the stability and formation of arc should be controlled, It can swing properly, and the forming shall be well combined with the necessary swing.

Spiral welded pipe: it is made by rolling low-carbon structural steel or low-alloy structural steel strip into pipe blank according to the viewpoint of certain spiral line (called forming angle), and then welding the pipe seam. It can produce large-diameter steel pipe with narrow strip steel. Spiral welded pipe is mainly used for oil and natural gas transportation pipeline, and its standard is expressed by outer diameter * wall thickness. Spiral welded pipe has single-sided welding and double-sided welding. The welded pipe shall ensure that the hydrostatic test, tensile strength and cold bendingof the weld meet the requirements.

Most 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),Products Show 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,رانكيلC276 سلس الأنابيب المصنعةالعوامل المؤثرة على تغيرات الأسعار and the load can be evenly dispersed, which obviously improves the performance of the reinforced concrete structure. According to the practice test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh.

j 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, 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,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd small types multi specifications and high precision. Therefore, it is widely used

AClassification by production method

CWelcome calls For the surface mesh of the height difference plate, when the height difference is ≤ mm, the surface mesh can be bent and installed; when the height difference plate is more than mm, the surface mesh should be disconnected at the place with height difference and put into the beam respectively. The anchorage length of the reinforcement is required for the reinforcement to extend into the beam.

dZThe 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.

In addition, galvanized steel is more expensive than ordinary steel pipes, so installing them requires a lot of financial costs.

Quality assurancer Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming, double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure, wharf, bridge, etc.

O→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.

First, the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam, on which the prefabricated micro bending plate shall be installed. The second is to erect prefabricated sidewalk beams in the cantilever part of the cantilever beam. The sidewalk beams of bridge openings on both sides are longer than the main beam, one end is supported on the cantilever beam of side pier, and the other end is supported on the special buttress on the embankment, which is to avoid widening the abutment.

dLevisGalvanized pipes are used in construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation support, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, boiler construction, highway railing, house construction, pressure vessel, oil storage tank, bridge, power plant equipment, Hoisting and transportation machinery and other welded structural parts with high load.

Galvanized pipe is a name for square pipe, that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment. Steel pipe has been an essential material in building decoration. Galvanized pipe is also used more in decoration, but hot-dip galvanized steel pipe manufacturers need to know about the size of galvanized pipe and several common sizes of galvanized pipe, which is helpful for your purchase!
