The electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics， after deducting the steel consumption increased by unit lapping， it can also save about % of the steel. After it is transported to the site according to the construction degree of the project， it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site， which saves the site and increases the management level of the site. At the same time， it can also solve the problems of noise pollution caused by straightening reinforcement.

gSaniaI-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure，Products Show vehicle manufacturing，Chatham KentA335p11 American Standard High Pressure Alloy PipeQuels aspects sont principalement utilisés pour other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.
Effect of trace elements on properties of galvanized pipe
TWarwick There is a great demand for welded steel mesh in Chinas market.
Zo 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， air and steam， which is made of hot-rolled steel strip coil as pipe blank， if it is not welded that is， when the extrusion molding is used for mm diameter pipe fittings， the investment of machinery and equipment is less， so the raw material consumption is also very small， and the technology is relatively perfect. Once the tube size is increased，Products Show the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore， the automatic control system will be upgraded.
TSteel transfers heat excellently; Can withstand high temperature; Strong and strong materials; Probably a long time ago. In addition， there is the low cost of metal.
CGood quality Carbon: the higher the carbon content， the higher the hardness of steel， but the worse its plasticity and toughness
dDWelded 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， 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.
Steel pipes can be classified by their models:
The 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，Chatham KentA335p11 American Standard High Pressure Alloy PipeQuels aspects sont principalement utilisés pour 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.
Meticulous workmanshipkGalvanized 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.
XThe section of I-beam has good straight pressure and tensile resistance， but the section size cannot resist torsion because the wing plate is too narrow. On the contrary， H steel has its own advantages and disadvantages.
There are many types of galvanized pipes， mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use， if in normal working environment，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd the thickness of galvanized layer of hot-dip galvanized seamless steel pipe is up to μ M above， and it has been used safely for about years. It can be seen that its service life is very long. Of course， when purchasing， we should also find regular manufacturers to order. Only in this way can we achieve this service life. As long as the galvanized pipe is cleaned after pickling， it is basically cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank. In order to ensure the quality， electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way， although it is much cheaper in price. However， the quality is very good when used， and it is also easy to have problems.
zSaniaIn 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.
iTIn order to ensure the welding quality of welded pipe， the forming roll guide roll， extrusion forming roll and sizing roll must be adjusted once， 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， controlling the edge springback of the finished rolled pipe， and ensuring that the weld is vertical without screwing into the extrusion roll.
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， the bound or welded mesh has better application quality.
