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.
8External steel bonding reinforcement method is a more traditional reinforcement method. The utility model uses an adhesive to paste the steel plate or reinforcement mesh on the cracked part of the wall to achieve the purpose of reinforcement. The commonly used adhesive is usually epoxy resin. This method is simple and fast in construction and has little impact on production and life. Basically， the bearing capacity of the wall can be greatly improved without changing the shape and internal use space of the components. It is mainly applicable to the reinforcement of walls that do not allow to increase the section size of original components，Products Show including more than plants under more than companies in countries.
Dq If the surface of the welded pipe is rusty，San Rafael AribaAlloy pipe GH2132Internet marketing brings new opportunities for development we can polish the appearance of the welded pipe with a wire brush to prevent rust.

Pickling: if the material cannot be removed after cleaning， pickling will be selected. Pickling of galvanized pipe is divided into chemical and electrolytic. How to prevent white rust of galvanized seamless steel pipe? It has a certain anti-corrosion effect on the pipeline.
hKey technical characteristics of alloy pipe:
GStretch punching by steel plate equipment; The main purpose is to be used in the structure of scaffold.
NWhere can I find it?Classification by section shape
fUThe use of welded steel mesh can make the project construction convenient. As long as the welded reinforcement mesh is laid as required the concrete can be irrigated， eliminating the links such as on-site cutting， placing and binding of reinforcement one by one.
Galvanized pipe has excellent corrosion resistance. Compared with traditional steel，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd its application life is longer. Secondly， this kind of pipe has strong resistance to baking. In case of critical situation， it will not lead to the collapse of building structure in a short time. In addition， this kind of pipe also has a practical advantage， that is， it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction，Products Show and the operation efficiency has been greatly strengthened. In this regard， it is not difficult to understand why the galvanized pipe is so favored by various construction units.
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.
quality standardzLongitudinal welded pipe has the advantages of simple production and processing technology， high production efficiency， low cost and rapid development trend. The compressive strength of spiral welded pipe is generally higher than that of straight welded pipe. Narrow blank can be used to produce welded pipe with large pipe diameter，San Rafael AribaAlloy pipe GH2132Internet marketing brings new opportunities for development 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 ~ ， general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.
yGHowever，Products Show compared with plastics， these pipes， like other metals， remain stable and will not be affected by high temperature.
They are not affected by surrounding factors and processes， including corrosion.
