8 For the surface mesh of the height difference plate，Bahamas310S SST Seamless Control Manufacturer tel.Méthodes de maintenance et de dépannage when the height difference is ≤ mm， the surface mesh can be bent and installed; when the height difference plate is more than mm， the surface mesh should be disconnected at the place with height difference and put into the beam respectively. The anchorage length of the reinforcement is required for the reinforcement to extend into the beam.
aTorontoI-beam is widely used
Generally， what are the customers requirements and standards during acceptance? When the galvanized pipe is accepted， 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.
UreadGalvanized pipe features:
RqThe production methods of seamless pipe are roughly divided into cross rolling method and extrusion method. The cross rolling method is to drill the tube with a cross roll， and then extend it to the rolling mill. This method has fast production speed， but has high requirements for the workability of the blank. It is mainly suitable for the production of carbon steel and low alloy steel pipes. The extrusion law is to pierce the blank or ingot with a punch， pull the pipe to the pipe and tilt it to make the steel pipe gradually thinner and longer. Another method is cold rolling. The method of applying the hot smoke invented by brother to cold processing. The cold working of seamless pipe can improve the dimensional accuracy and finishing of steel pipe，Products Show and improve the mechanical properties of materials.
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， 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， 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，Products Show and it is also easy to have problems.
What are the advantages of seamless pipe?
wC-section steel has uniform zinc layer， smooth surface，Bahamas310S SST Seamless Control Manufacturer tel.Méthodes de maintenance et de dépannage strong adhesion， no zinc scar， no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer， and the zinc content on the surface is usually -g /? It has long service life corrosion resistance and durability. It is a kind of stronger protection.
E Fabrication and installation of pipe support:
SAdministrationThe 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，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd 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.
gSPackaging: Welding nets are generally packaged in paper (mostly gray white， yellow， etc.)， some similar to welding wire diameter welding nets， agriculture， construction， transportation， mining and other industries. Such as machine shields， animal fences， flower and tree fences， window fences， aisle fences， poultry cages， baskets and decorations.
Installation of galvanized pipe and precautions
Classification by wall thickness
Discountf According to the pipe wall thickness， pipes made of relatively thin materials such as steel strip can be welded with high frequency， and some thin-walled pipes can be welded with shielding gas; Pipes with wall thickness more than mm can be welded by hand.
VThe crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width， the more serious the disadvantages.
The pipeline shall be positioned according to the drawing design， and the pipeline support shall be prefabricated according to the site conditions. Hang the wire from the th floor down and fix the support.
cTorontoLongitudinal 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 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.
cASince the s， with the rapid development trend of high-quality hot strip mill production and the development of electric welding and testing technology， the welding quality has been continuously improved， the types， specifications and models of welded steel pipes are increasing， and seamless pipes have been replaced in more and more industries. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the way of welding. Classified by production mode: classified by processing technology - electric arc welded pipe， (high frequency， low frequency) gas welded pipe furnace welded pipe.
