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,بلميربن42CrMo أنابيب الصلب غير الملحومة مصنعمواصفات المنتج بضغط العمل والمعلمات but the general compressive strength is less than that of seamless pipe.

4The smooth of steel pipe is mainly through tension reducing, which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality, the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process, and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.

rSuriThe shape of I-beam is similar to that of H-beam. What is the difference between them?

The development of steel mesh has met the soft and hard conditions.

KBendabIn our daily life and work, we can often see a lot of steel products. At the same time, among many steel products, the figure of galvanized pipe is particularly prominent. This is because this kind of pipe will be applied to many engineering construction we often see in our life. There are also countless products processed with this kind of pipe. For example, in the field of mechanical equipment processing we often see, the application of galvanized pipe is more frequent. Let&#;s discuss the application scope of this kind of pipe today.

Iz Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility,Products Show 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.

Galvanized pipe is often seen in our daily life, especially in some construction sites. This product has the advantage of durability when used. It also has the characteristics of surface gloss, uniform zinc layer and no missing plating. Moreover, the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings. In addition, this product also has the characteristics of no dripping, strong adhesion, breaking the clean Legion and strong corrosion resistance. Even if it is used in some places where the environment is not good,Products Show its service life is also very long, and it also has the characteristics of corrosion resistance. The standard anti rust thickness of hot-dip galvanizing can be maintained for more than years without repair. This is used in some suburban environments. However,بلميربن42CrMo أنابيب الصلب غير الملحومة مصنعمواصفات المنتج بضغط العمل والمعلمات in urban or offshore areas, standard urban or offshore areas can be maintained for years without repair. The products produced by our company must meet these requirements. Friends who need to order can call us directly.

Compared with manual binding, eliminating the links of reinforcement on-site cutting, placing one by one and binding. It can save % - % of working hours, greatly accelerate the construction progress and shorten the construction cycle.

aWhat is the stainless steel passivation of alloy pipe?

CThe production methods of seamless pipe are roughly divided into cross rolling method and extrusion method. The cross rolling method is to drill the tube with a cross roll, and then extend it to the rolling mill. This method has fast production speed, but has high requirements for the workability of the blank. It is mainly suitable for the production of carbon steel and low alloy steel pipes. The extrusion law is to pierce the blank or ingot with a punch, and then squeeze it with a steel pipe with an extruder. The efficiency of this method is lower than that of cross rolling method. It is suitable for producing high-strength alloy steel pipe. The billet or ingot must be heated before cross rolling method and extrusion method. The produced steel pipe is called thermal correlation. Steel pipes produced by hot working can sometimes be cold worked as needed. There are two methods of cold working. One is cold drawing. In other words,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd pull the pipe to the pipe and tilt it to make the steel pipe gradually thinner and longer. Another method is cold rolling. The method of applying the hot smoke invented by brother to cold processing. The cold working of seamless pipe can improve the dimensional accuracy and finishing of steel pipe, and improve the mechanical properties of materials.

Jtechnical service Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base, hot-plated parts can be formed by cold stamping, rolling wire drawing, bending and so on without damaging the coating;

kTThis phenomenon is affected by cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the plastic deformation non-uniformity and residual stress caused by thermal stress during cooling.

Precautions for galvanized pipe storage

When excavating a tunnel in a stratum where the rock is not hard and complete, it is generally necessary to excavate a diversion pit (also known as pilot hole) and set temporary support.

Affordable pricedSteel pipes can be classified by their models:

XI-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:

The zinc coating is thick, the crystallization is detailed, uniform and non porous, and the corrosion resistance is excellent;

ySuriHardness of reinforcement construction of reinforced mesh on concrete bridge deck; Including key lime mixing and packaging materials, you need to pay attention to calculating the size of the building, and the calculated specifications must meet the quality standards and construction standards.

tY Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation (SY / t- is a submerged arc welded steel pipe for general low-pressure fluid transportation such as water, gas, which is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming and double-sided active submerged arc welding or single-sided welding.

Are there many welded types of mesh produced? According to the welding type and overall improvement, the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh
