General carbon steel wire sleeve (GB / t- is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings and installation of machinery and equipment.
5What are the advantages of seamless pipe?
eGarlandI-beam features: the content of chromium carbon alloy is -%， the hardness of chromium carbide alloy is V， and the macro hardness is - HRC
Carbon: the higher the carbon content， the higher the hardness of steel， but the worse its plasticity and toughness
JJilongGalvanized pipe features:
Sn The weight of seamless pipe is light and its weight is only one fifth of that of anti steel.
The advantages of shiny galvanized pipe are:
The rapid popularization and application of cold drawn ribbed bars and hot rolled grade III bars in China provides a good material basis for the development of welded mesh. The formal implementation of welding net product standards and application procedures has played a positive role in product quality and accelerating popularization and application.
c Frame line crack
X The surface of hot-dip galvanized parts is bright and beautiful.
VManufacturing cost According to the purpose， the welded pipe has general purpose and high temperature and high pressure. The pipe used in the latter is often special alloy steel. The problem of shrinkage cracks in the welding process and the mechanical properties of the pipe in the heat affected zone must be considered and solved，Products Show and the mechanical properties of the pipe in the heat affected zone will not be greatly changed due to the influence of welding operation.
iKGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section，Hyelia16Mn seamless pipe factoryWhat are the hazards which is made of Q hot-rolled or cold-rolled strip or coil as the base material， cold bending and high-frequency welding. In addition to wall thickness thickening， the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe. Good comprehensive mechanical properties， weldability， and good low temperature toughness.
Operating conditions
Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.
Excellent qualityeGalvanized pipe is a layer of galvanized ordinary steel. This is a layer and is a great anti-corrosion protection.
PAt the same height，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd light I-beam has narrower legs， thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam， and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications， dimensions and relevant standards.
The zinc coating is thick， the crystallization is detailed， uniform and non porous，Products Show and the corrosion resistance is excellent;
cGarland According to the process， it is divided into arc welded pipe， resistance welded pipe (high frequency and low frequency)， gas welded pipe and furnace welded pipe.
dKGalvanized pipe can be seen from its name. It is a square pipe type. Many materials can form galvanized pipe body. It is used for what purpose and where. Most galvanized pipes are steel pipes. After unpacking leveling，Hyelia16Mn seamless pipe factoryWhat are the hazards crimping and welding， they form round pipes， which are rolled into square pipes， and then cut into the required length. Generally，Products Show there are galvanized pipes in each package. In terms of spot， most of them are in large specifications， ranging from * * .- to * * - Galvanized pipes are divided into structural galvanized pipes， decorative galvanized pipes， architectural galvanized pipes， mechanical galvanized pipes， etc.
Galvanized pipe: the zinc layer of cold galvanized pipe is an electroplating layer， and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore， its corrosion resistance is poor. In new homes， it is forbidden to use cold galvanized pipes as water supply pipes.
