According to the shape of the product， special flour， welding or ordinary thread connection shall be used.
4 In order to ensure the welding quality of pipes， welders shall be trained， tested and qualified. In addition to the basic theory， the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding，Products Show vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large，san diego 10Cr9Mo1VNb alloy pipeWide range of applications the stability and formation of arc should be controlled， It can swing properly， which is not easy to have the disadvantages of staggered joint， welding deviation and incomplete penetration， mostly a multi grid box separated by spacer mesh.
QCartoon Bella Platform reinforcement mesh is a widely used reinforcement mesh product， such as industrial maintenance platform， berm etc. this kind of reinforcement mesh is widely used in industry， municipal administration， electric power，Products Show 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.
OxWelded 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， many types， specifications and models， and less investment in machinery and equipment projects，Products Show but the general compressive strength is less than that of seamless pipe.
Galvanized pipe， also known as galvanized pipe，san diego 10Cr9Mo1VNb alloy pipeWide range of applications is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick， the coating is uniform， the adhesion is strong and the service life is long. The electroplating cost is low， the surface is not smooth， and the corrosion resistance is worse than that of hot dip galvanized pipe.
The end span plate is connected with the load-bearing wall. The length of the surface mesh extending into the grid support shall not be less than mm， and a transverse reinforcement shall be provided at the end of the mesh or the extended reinforcement shall be bent.
sIntroduction to product knowledge of alloy pipe:
VThe whole structure is composed of zinc and quaternary crystals， forming dense crystals and barrier layer on the plate， which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd when the zinc sacrificial anode is at the forefront of protection， the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.
OPrice Pipe installation
uGWelded pipes with large or thick diameter are usually made of steel blank immediately， while small welded pipes and thick wall welded pipes must only be welded immediately according to nylon tape. After simple grinding and polishing metal wire drawing is OK.
Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh， steel mesh， hook mesh， etc.， but its cost is much higher， and it is rarely used under normal circumstances
What is theof defect detection of seamless pipe? Magnetic particle testing or penetrant testing of seamless pipes can effectively find surface defects such as cracks， folds double skin， hair lines， pinholes and so on. Because of its high detection sensitivity， magnetic particle detection method should be preferred for ferromagnetic materials. For non ferromagnetic materials， such as stainless steel seamless pipe， penetrant testing method is adopted.
Word of mouth recommendationz Welded steel mesh， is especially suitable for large-area concrete engineering.
XBecause alloy pipe is a very unique pipe fitting， we must use appropriate methods to carry out installation in the case of installation， so as to ensure the performance index of the data. Generally， when installing alloy pipes， we will use some flanges and elbows to fix them， so as to ensure that the raw materials can be fixed very well. Therefore， when we carry out use， we must ensure the quality of flanges and elbows， so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline， they must be installed together.
The use of hot dip galvanizing has expanded with the development of industry and agriculture. Therefore， hot-dip galvanized products have been widely used in industry (such as chemical equipment petroleum processing， marine exploration， metal structure， power transportation， shipbuilding， etc.)， agriculture (such as sprinkler irrigation， construction (such as water and gas transportation， wire casing， scaffold， house， etc.)， bridges， transportation， etc. because hot-dip galvanized products
mDalas Spray is OK. This method can not only completely remove rust， oxide and dirt， but also the welded pipe will be affected by abrasive impact and friction， resulting in the average roughness of the welded pipe.
iK After hot-dip galvanizing of steel structure， it is equivalent to one-time annealing treatment， which can effectively improve the mechanicalof steel matrix， eliminate the stress during steel forming and welding and is conducive to turning of steel structure.
In view of the current market environment， especially in terms of construction or equipment manufacturing technology， the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life， even in a field that seems to have little contact. It will be applied in many construction projects. At the same time， even in the depressed environment of the steel industry， the application situation and utilization rate of this kind of pipe are very high.
