Generally in terms of strength, 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, 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, redox method and characteristic table.

1Galvanized pipe: the hot-dip galvanized pipe base plate and molten electroplating solution are combined physically and chemically to form a dense corrosion-resistant structure of zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore it has strong corrosion resistance.

iSt. JohnWelded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated,Products Show insulated and cooled in a certain medium,ليفيسDN80 المجلفن الأنابيب كم لكل مترالتدابير التي يمكن اتخاذها من حيث التكنولوجيا and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.

In the production process, the corrosion protection is not corroded. This is the thickness of zinc, and the quality and strength of its coating depend on longevity.

Ztalc Product description of galvanized pipe

Li Platform reinforcement mesh is a widely used reinforcement mesh product, such as industrial maintenance platform,Products Show berm, etc. this kind of reinforcement mesh is widely used in industry, municipal administration, electric power, coal mine and other fields, and has the strongest resistance to surface impact, especially the reinforcement mesh with a cross bar spacing of mm has a strong ability to resist lateral impact.

uWhat should we pay attention to in the production of alloy pipe

YThe seamless pipe produced by the seamless pipe manufacturer is a long seamless pipe without any joints around and with hollow section. The thicker the wall of this product produced by the manufacturer the higher the use value and economic value of this product. If its wall thickness is thinner, its processing composition will increase significantly, Secondly, the product technology produced by this seamless pipe manufacturer often determines its limitations.

NWhere can I find it? China is a big steel country.

pK Seismic and cracking performance the longitudinal and transverse bars of the welded reinforcement mesh form a network structure, so it has good bonding and anchorage with the concrete, and the load can be evenly distributed which obviously shows the seismic cracking performance of the reinforced concrete structure. According to the actual test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. It greatly reduces the unnecessary cost generated manually in the construction and shortens the construction period. The use of reinforcement mesh is simple and convenient,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and the reinforcement mesh is convenient for transportation.

It 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, electric welding special-shaped pipe, scaffold pipe and spiral welded pipe.

Longitudinal welded pipe has the advantages of simple production and processing technology, high production efficiency, 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.

RPass design

Hot rolled smooth round steel is structural steel, with chemical composition content of C carbon .%, Si silicon .%, Mn manganese %, s sulfur ≤ .%, P phosphorus ≤ .%, yield strength of mpa and tensile strength of MPa. High temperature continuous casting and rolling or ingot heating rolling. Soft, good weldability, high ductility,.

uSt. John Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.

eG Welded steel mesh is aesthetically pleasing.

There are five main guarantee measures for steel pipe welding. If these five aspects are guaranteed, the quality of galvanized pipe can also be guaranteed.
