Oxygen blowing welded pipe: it is used as steel blowing pipe. Generally, small-diameter welded steel pipe is used. There are eight standards from / inch to inch. Made of , , , or q-q steel strip. In order to prevent corrosion, some are aluminized.

4Galvanized pipe,Products Show also known as galvanized pipe,San AntonioAlloy pipe for power plantPlease choose the right way to use is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick, the coating is uniform, the adhesion is strong and the service life is long. The electroplating cost is low, the surface is not smooth, and the corrosion resistance is worse than that of hot dip galvanized pipe.

rSan RamonX-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas,Products Show heating steam and other general liquids X-ray or ultrasonic testing sampling inspection (%) shall be carried out.

Spiral seam submerged arc welded steel pipe (SY- for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation, often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests it is safe and reliable to use. The steel pipe has large diameter and high transportation efficiency, and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.

OMachelen . 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).

KaGenerally in terms of strength, toughness and mechanical properties. There are many differences. Hot dip galvanized pipe: the coil formed by welding the square pipe with steel plate or steel strip is placed in the galvanized tank on the basis of the square pipe to form a series of chemical reactions on the square pipe. The production process of hot-dip galvanized steel pipe is simple, the production efficiency is very high, and there are many varieties and specifications. The demand for RHS by equipment and capital is very small, which is suitable for the production of small galvanized steel pipe plants. However the strength of steel is much lower than that of seamless steel pipe. It is mainly used for drying, redox method and characteristic table.

Galvanized pipe is a kind of light thin-walled steel pipe with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size,Products Show which is made of Q hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding. In addition to wall thickness thickening,San AntonioAlloy pipe for power plantPlease choose the right way to use the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe.


San



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 effect of thermal expansion and cold shrinkage and the characteristics of concrete, the cracking of surface layer is significant.

tBecause the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different, the use of I-beam should be reasonably selected according to the mechanical properties,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd chemical properties weldability and structural size of I-beam.

FSeamless pipe

PQuality improvementAcceptance according to standards

vZSteel pipes can be classified by their models:

Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh, steel mesh, hook mesh, etc., but its cost is much higher, galvanized steel is more expensive than ordinary steel pipes, so installing them requires a lot of financial costs.

Lets seeqThe reinforced concrete surface reinforcement method has the advantages of simple construction technology and strong adaptability, which can greatly improve the bearing capacity, flexural stiffness and ductility of the brick wall. At the same time, its natural frequency can be changed to improve its performance in normal use. It is mainly applicable to the solid wall, porous hollow brick wall and mm thick empty bucket brick wall with no cracks and shear in the original wall.

KI-beam: national standard * what is the wall thickness of I-beam

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. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However, there are many types of it. When you buy it, you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next, Xiaobian will lead you to see the advantages of galvanized pipe.

iSan RamonIf 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.

gWGalvanized 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.

Metric welded pipe: it is used as seamless pipe in standard. The welded steel pipe expressed by outer diameter * wall thickness mm is welded by hot and cold strip welding of general carbon steel, or it is made by cold drawing after hot strip welding. Metric welded pipe is generally used as structural parts, such as transmission shaft, or to transport fluid. The thin wall is used to produce furniture and lamps. It is necessary to ensure the strength and zigzag test of steel pipe.
