Idler 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.

3In order to ensure the welding quality of welded pipe, the forming roll,Products Show extrusion forming roll and sizing roll must be adjusted once,Manhattan108 welded pipe weight per meterEconomic slowdown is a healthy adjustment and then the most important thing is to adjust the closing plate hole, guide roll and extrusion forming roll of the forming roll. Among them, the guide roller has the s of controlling the weld direction of the welded pipe and the height width ratio of the finished rolled pipe, reducing the edge widening, controlling the edge springback of the finished rolled pipe, and ensuring that the weld is vertical without screwing into the extrusion roll.

jSan AntonioWhether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, what are the customer&#;s requirements and standards during acceptance? When the galvanized pipe is accepted,Products Show you can judge whether it is qualified from the appearance, or whether there are problems such as missing plating or bubbles on the outer wall of the whole square pipe. Only by solving these problems in time can it be judged as qualified and better used.

NMenciuello If the surface of the welded pipe is rusty, we can polish the appearance of the welded pipe with a wire brush to prevent rust.

VpThe 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.

Why are galvanized pipes so good?

Classification supplement

aThe sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film,Products Show which determines that the color of the surface layer has no change before and after passivation treatment and the reproducibility of the solution is good.

YHow to judge the quality of seamless pipe?

CMarket trendLongitudinal welded pipe has the advantages of simple production process, high production efficiency low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank,Manhattan108 welded pipe weight per meterEconomic slowdown is a healthy adjustment and welded pipe with different pipe diameter with blank of the same width. However, the weld length increases by ~ , and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly, while small welded pipes and thin-walled welded pipes only need to be welded directly through steel strip. Then after simple polishing, wire drawing is OK. Welded pipe is welded with strip steel, so it is not as high as seamless pipe in its original position. Welded pipe process: uncoiling of raw materials - leveling - end shearing and welding - looper - forming - Welding - removal of internal and external weld beads - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - Inspection (strict control) - Packaging - delivery.

uGGalvanized pipe, also known as galvanized pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd 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.

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

During the construction of building wall, cracks and hollows show that the construction materials are unqualified, the construction at the matrix junction is not in place, and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh, which can prevent cracking and strengthen the wall.

Lets seem Steel pipe with complex section -- unequal hexagonal steel pipe, five petal quincunx steel pipe, double convex steel pipe, double concave steel pipe, melon seed steel pipe, conical steel pipe, corrugated steel pipe, watch case steel pipe and others.

H Remove defective pipes within the allowable length.

The reinforcement mesh of the maintenance platform has the characteristics of extensive application, beautiful style, convenient installation and durability, Skirting plate (edge guard plate), checkered plate guard plate, installation of connectors and other accessories can be added around. The reinforcement mesh is suitable for the reinforcement mesh manufactured in the factory and welded with cold-rolled ribbed reinforcement or cold-rolled smooth round reinforcement. The welded reinforcement mesh for reinforced concrete is a good and efficient material for concrete distribution. Flat steel with different specifications can be used for edge wrapping, Or wrap edges with angle steel, channel steel, square tube, etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.

fSan AntonioSeamless pipe has a high position in steel pipe, and there are many large factors. The main usage has accounted for more than %, which is applicable to all walks of life. Seamless pipe factories in China are widely produced. At present, the number of factories in China is also increasing every year, which is determined by the nature and production conditions of seamless pipe. The common production processes and processes are more complex.

eLThe 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.

However, compared with plastics, these pipes, like other metals, remain stable and will not be affected by high temperature.
