Speed up the construction progress: weld the mesh with reinforcement to allow the rapid construction of the project. The required laying of welded steel bars is provided, so concrete can be poured, steel cutting, stitching, etc., and the arrangement can be strengthened. ? saving construction time? The construction progress is greatly accelerated and the construction period is shortened.

2 The end span plate is connected with the load-bearing wall. The length of the surface mesh extending into the grid support shall not be less than mm,Products Show and there shall be no staggered joint during assembly. Electric welding positioning is generally spot welding. After inspection and straightening,Oshava20CrMnTi alloy pipeShip at any time the free conversion method shall be used for welding as far as possible.

OBigner After chromate passivation, the zinc coating forms white, colorful and military green, which is beautiful and generous and has certain decoration;

XgThere are many processes in the process of welded pipe processing, and every detail needs our attention. Welded pipes need to be treated by various processes before application. Heat treatment of welded steel pipe is an important link in the process of welding steel pipe. Hot working is a metal hot working process in which metal materials are heated, and the metal properties are controlled by changing the metallographic structure on the surface or inside of the material.

The 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.


The vertical of the processed reinforcement bar shall be divided into small sections as required.

y 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,Products Show 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

A When the end span plate is connected with the concrete beam for structural reinforcement, 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),Products Show when the beam width is small, the extended reinforcement shall be bent.

MGood qualityLongitudinal welded pipe has the advantages of simple production and processing technology,Oshava20CrMnTi alloy pipeShip at any time high production efficiency, low cost and rapid development trend. The compressive strength of spiral welded pipe is generally higher than that of straight welded pipe. Narrow blank can be used to produce welded pipe with large pipe diameter, and blank with the same total width can also be used to produce welded pipe with different pipe diameter. However, compared with the straight seam pipe with the same length, the welding length is increased by ~ , and the production rate is low.

kBGalvanized 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,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd it is forbidden to use cold galvanized pipes as water supply pipes.

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.


In the production process, the stainless glittering pipe is affected by the outside and product surface. Due to galvanizing, the corrosion protection is not corroded. This is the thickness of zinc, and the quality and strength of its coating depend on longevity.

Professional is kingn The finished products shall be placed away from the processing site and stacked in the designated finished product warehouse. Ventilation and other facilities shall be provided in the storage environment.

ZNitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present gas nitriding is widely used in the production of alloy steel pipe.

It is also divided into general welded pipe, galvanized welded pipe, oxygen blowing welded pipe, metric welded pipe, idler pipe, deep well pump pipe automobile pipe, transformer pipe, electric welding thin-wall pipe, electric welding special-shaped pipe, scaffold pipe and spiral welded pipe.

dFlourishingSince the s, with the rapid development trend of high-quality hot strip mill production and the development of electric welding and testing technology, the welding quality has been continuously improved, the types, specifications and models of welded steel pipes are increasing, and seamless pipes have been replaced in more and more industries. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the way of welding. Classified by production mode: classified by processing technology - electric arc welded pipe, resistor welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.

fY According to the pipe wall thickness pipes made of relatively thin materials such as steel strip can be welded with high frequency, and some thin-walled pipes can be welded with shielding gas; Pipes with wall thickness more than mm can be welded by hand.

Tungsten; can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steel
