The pipeline shall be positioned according to the drawing design and the pipeline support shall be prefabricated according to the site conditions. Hang the wire from the th floor down and fix the support.

3Galvanized pipe: the zinc layer of cold galvanized pipe is an electroplating layer, and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore, its corrosion resistance is poor. In new homes, it is forbidden to use cold galvanized pipes as water supply pipes.

qSantiago→ wide flange and large lateral stiffness. Strong bending resistance.

Galvanized pipe refers to the shape and high frequency of hollow square steel pipe welded by the back of the steel pipe during the hot rolling or cold rolling of galvanized steel plate or cold bending of galvanized steel plate, or before the galvanization of cold hollow pipe. Galvanized. Galvanized square pipe can be divided into hot galvanized pipe and cold galvanized pipe from the production process. This is because the two galvanized pipes are different, which also leads to many different physical and chemical properties.

SAccra From the current scope of use,Products Show it is mainly widely used in glass curtain wall,Mercedes.Combien coûte 600 tubes soudés par mètreComment maintenir un bon travail au quotidien power tower, communication power grid and other industries. In recent years, it has been widely used in many regions and industries, which is enough to show that the quality of galvanized pipe is very good, and it also brings a lot of convenience in the process of use, so it can be used better.

Hm Application of galvanized pipe

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

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

oThe import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number,Products Show I-beam has no specific composition and performance series.

U Construction preparation

TOK or not?The reinforcement mesh of the maintenance platform has the characteristics of extensive application, beautiful style, convenient installation and durability, Skirting plate (edge guard plate), checkered plate guard plate installation of connectors and other accessories can be added around. The reinforcement mesh is suitable for the reinforcement mesh manufactured in the factory and welded with cold-rolled ribbed reinforcement or cold-rolled smooth round reinforcement. The welded reinforcement mesh for reinforced concrete is a good and efficient material for concrete distribution. Flat steel with different specifications can be used for edge wrapping, Or wrap edges with angle steel, channel steel, square tube, etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.

tD It is the trend of the development of steel bar industry to take the road of steel bar welding mesh in steel bar construction.

During the heating and cooling process of structural welded pipe workpiece, due to the inconsistent cooling speed and time of surface layer and core layer,Products Show the temperature difference will be formed, resulting in uneven volume expansion and contraction,Mercedes.Combien coûte 600 tubes soudés par mètreComment maintenir un bon travail au quotidien resulting in stress, namely thermal stress. Under the action of thermal stress, the starting temperature of the surface layer is lower than that of the core layer and the shrinkage is greater than that of the core layer, making the core layer stretch. At the end of cooling, under the action of thermal stress, the surface of the workpiece is compressed and the core is pulled.

Material requirements

Project scopetGalvanized steel pipe: in order to improve the corrosion resistance of steel pipe, general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.

DH-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter "H". There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd better mechanical properties per unit weight, and can save a lot of materials and construction time.

Classification by wall thickness

qSantiagoThe correct and reasonable use of galvanized pipe can play a better role. The product can be widely used in the market because of its obvious performance advantages. Both strength and toughness are worth our choice. Let&#;s see what the specific uses are and what the acceptance standards are?

aW Platform reinforcement mesh is a widely used reinforcement mesh product, berm, etc. this kind of reinforcement mesh is widely used in industry, municipal administration, electric power, coal mine and other fields, and has the strongest resistance to surface impact, especially the reinforcement mesh with a cross bar spacing of mm has a strong ability to resist lateral impact.

The 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.
