Material requirements

5Idler pipe: it is used for electric welding steel pipe of idler of belt conveyor. It is generally made of Q, QA, B steel and steel, with a diameter of -mm. There are certain requirements for pipe tortuosity, end face straightness with the center line and ovality. Generally, water pressure and flattening tests are carried out.

Construction preparation

Had dawadimi Are there many welded types of mesh produced? According to the welding type and overall improvement,Products Show 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,Lincoln.2205 tubes soudés en acier duplexIl y a des coups pour l'entretien et le nettoyage the bound or welded mesh has better application quality.

Fs Divided by weld -- straight welded pipe and spiral welded pipe.

Precautions for galvanized pipe storage


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.

bDehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlement

AInstallation of galvanized pipe and precautions

XreformEmulsified asphalt emulsion is also easy to use on the mobile slurry seal paver. It is necessary to mix on the machine and use additives for chemical control for maintenance.

xWThe preparations for the construction of high-speed reinforcement mesh include the preparation and inspection of raw materials, the inspection and acceptance of the lower layer of the pavement,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd 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.


In order to improve the corrosion resistance of steel pipe, the general steel pipe (black pipe) is galvanized. The galvanized pipe is divided into hot-dip galvanizing and electric steel zinc. The hot-dip galvanizing layer is thick and the cost of electric galvanizing is low, so there is galvanized pipe.

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

S The defects can be removed by grinding with sand wheel, 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,Lincoln.2205 tubes soudés en acier duplexIl y a des coups pour l'entretien et le nettoyage 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.

oW Seamless tube has high elasticity,Products Show no memory, no deformation, anti-static.

According to the historical records of the recent four years, the zinc price in the first quarter was generally higher than that in the whole year, and generally entered a wave of upward trend in the first quarter. However, zinc prices continued to decline in the first quarter of , and showed a trend of accelerating the decline day by day. There are two key reasons for the beginning of this year. First, the vicious change of the real estate industry has led to a rapid decline in the growth rate of China&#;s consumption of galvanized pipe and seamless steel pipe, and even a contraction month on month; Secondly, the blind expansion of galvanized pipe factory confused the sense of rhythm of supply and demand balance.
