Classification by end shape
9The advantage of the reinforcement mesh system is ecological. It is filled with natural stone materials. There is a gap between the stone materials to allow plants to grow in it. It can also plant plants on it. It has the dual effects of engineering slope protection and plant slope protection. The Ecological Grid mat is a combination with a height of cm ~ cm， mostly a multi grid box separated by spacer mesh.
jKamajunic.quality inspection is carried out for alloy pipes， so that the whole process of steel pipe processing is under reasonable inspection and supervision， the reinforcement on both sides extends into the beam， and the reinforcement anchorage length is required.
RValdes Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.
EqHow are seamless tubes made?
The laying of reinforcement mesh can speed up the construction speed and shorten the construction period. In order to reduce the impact of construction on road traffic， the reinforcement and maintenance works of the two bridges are expected to be completed in the middle of next month.
Transformer tube: it is used to make transformer heat dissipation tube and other heat exchangers. It is made of general carbon steel. Flattening，Products Show zigzag and hydraulic tests are required. Steel pipes are delivered in fixed length or double length，JoviranosCombien coûte le tube 219?La principale tendance de développement and there are certain requirements for the tortuosity of steel pipes.
rDifference and application description between H-beam and I-beam
L . the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm， and the bending diameter shall not be less than D (D is the reinforcement diameter).
Qhow muchWelded pipe refers to the steel pipe with joints on the surface， which is welded after the steel strip or steel plate is bent and deformed into circular， square and other shapes. The blank used for welded pipe is steel plate or steel strip. How can the steel strip or steel plate be welded together， and what are the welding skills?
qIThe two ends of the steel produced by the seamless pipe manufacturer shall be cut into right angles， and the burrs on the surface shall be removed， which is the raw material used by the seamless pipe manufacturer. The embryo prototube embryo needs to be cut by a cutting machine to form an embryo material with a length of about one meter which is sent to the furnace for heating through the conveyor belt. The billet is sent to the furnace. After internal heating， the temperature is about degrees， and the fuel used is often ethyne. Temperature control in the furnace is a very key factor.
Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base，Products Show hot-plated parts can be formed by cold stamping， rolling， wire drawing， bending and so on without damaging the coating;
The whole structure is composed of zinc and quaternary crystals， forming dense crystals and barrier layer on the plate， which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer， when the zinc sacrificial anode is at the forefront of protection， the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.
Superior qualityg Simple section steel pipe -- circular steel pipe， square steel pipe， oval steel pipe，Products Show triangular steel pipe， hexagonal steel pipe，JoviranosCombien coûte le tube 219?La principale tendance de développement rhombic steel pipe， octagonal steel pipe， semi-circular steel pipe others.
KThe shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.
The tensile strength of seamless pipe is more than ~ times that of ordinary steel， the elastic coefficient is better than that of steel， and has good creep resistance， corrosion resistance and seismic resistance.
oKamajuniOn the other hand， when the steel structure changes during heat treatment， that is，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd austenite transforms into martensite， the increase of specific volume will be accompanied by the expansion of workpiece volume， and each part of workpiece will undergo phase transformation successively， the tensile stress on the surface and the compressive stress in the heart are just opposite to the thermal stress. The magnitude of microstructure stress is related to the cooling rate， shape and chemical composition of martensitic transformation zone materials.
kVWire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin， which is mostly used after coating or galvanizing， and cold bending test is required.
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.
