The grid spacing size and number of reinforcement of electric welding reinforcement mesh are correct, which overcomes the phenomenon of large spacing size error and missing binding and buckle of binding quality caused by manual placement of reinforcement in traditional manual binding. The welded steel mesh has high strength and good elasticity. When pouring concrete, the steel bar is not easy to be partially bent and does not change. Because it is considered that the longitudinal and transverse steel bars are spot welded into a mesh structure, so as to achieve the goal of side-by-side average stress and bonding anchor.

8They do not need to protect them from mechanical damage.

lLesbridgeUsing alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time,Products Show such as roller bearing ring throwing Nowadays,بيكرينغIncoloy825 سبيكة أنابيبتوصيل seamless steel pipe has been widely used to produce hydraulic jack sleeve.

Galvanized pipe features:

DMarseille Because the zinc coating has excellent ductility, rolling, bending and so on without damaging the coating.

GbHigh percentage of metal strength.

Welded steel pipe, also known as welded pipe, is a seamless steel pipe made of thick steel plate or hot-rolled strip by electric welding after coiling and forming, generally with a fixed length of m. Welded steel pipe has the advantages of simple production and processing process, high production efficiency, many types, specifications and models,Products Show and less investment in machinery and equipment projects, but the general compressive strength is less than that of seamless pipe.

Galvanized pipe has excellent corrosion resistance

iLast week, the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, the leading city, rose first and then stabilized in four trading days, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, Tangshan billet fell by yuan during the Dragon Boat Festival holiday. On the first day after the festival, although the phase snail is still running at a low level, due to the small billet resources in the market, the steel mills unexpectedly rose,Products Show and the billet market rebounded. However, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials,بيكرينغIncoloy825 سبيكة أنابيبتوصيل the steel plant has always maintained a cautious wait-and-see attitude to maintain stability.

S According to the purpose, the welded pipe has general purpose and high temperature and high pressure. The pipe used in the latter is often special alloy steel. The problem of shrinkage cracks in the welding process and the mechanical properties of the pipe in the heat affected zone must be considered and solved and the mechanical properties of the pipe in the heat affected zone will not be greatly changed due to the influence of welding operation.

Aquery Main machines and tools

sQThe chemical composition of cold-rolled ribbed strip is the same as that of hot-rolled smooth round strip. It is rolled at room temperature with hot-rolled smooth disc strip, which is called cold rolling. Due to the reorganization of steel crystal structure by cold rolling process, high tensile strength (LL, ll, ll, etc.) is obtained, which has poor ductility and cannot be welded. If there are double-sided ribs and three-sided ribs,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd the specification allows LL to be used as stirrup. The design value of strength is limited to n / mm?.

Transformer tube: it is used to make transformer heat dissipation tube and other heat exchangers. It is made of general carbon steel. Flattening, flaring, zigzag and hydraulic tests are required. Steel pipes are delivered in fixed length or double length, business license organization code certificate, tax registration certificate, production and operation license and other qualification materials are complete. Look at the case investigate the supplier&#;s performance and the projects served in the past. Whether there is a self built logistics fleet or not, choosing a service provider with a self built logistics fleet can reduce the transportation cost, and more importantly, ensure the timeliness of delivery. After sales service, whether there is a sound and reliable after-sales service guarantee system, and timely solve quality problems in arrival acceptance and subsequent use. Check whether the quality assurance materials such as product quality certificate, material specification and warranty are complete. Check the appearance of the welded pipe, the surface is smooth and flat, the weld is dense, without burr, oil stain, corrosion, extrusion deformation and flat cross section. Use a micrometer to check whether the outer diameter and wall thickness of the welded pipe meet the requirements, and the standard wall thickness deviation shall not exceed % - %. NDT shall be carried out for welded pipe with flaw detector. Conduct bending tensile strength test according to the requirements, bend the welded pipe for degrees, and there is no crack at the bend.

Installation worksgSince 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.

Q Remove defective pipes within the allowable length.

From the comparison of the monthly summary apparent consumption data information of galvanized pipe and the real estate sales data information from to this year, they show the consistency of height width ratio, which not only shows a positive correlation in the overall new trend, but also significantly conforms to the fluctuation direction of the monthly development trend.

kLesbridgeIn building construction engineering, welded steel wire mesh is an essential heat preservation and crack prevention material. It has good performance and can take into account the unity between crack resistance and the requirements of face brick for base strength and the stability of heat preservation system.

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

In order to ensure the welding quality of pipes, welders shall be trained, 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, and the current cannot be adjusted in the middle of one formation). In the process, the stability and formation of arc should be controlled, and the forming shall be well combined with the necessary swing.
