Welded pipe refers to the steel pipe with joints on the surface， which is welded after the steel strip or steel plate is bent and deformed into circular， square and other shapes. The blank used for welded pipe is steel plate or steel strip. How can the steel strip or steel plate be welded together， and what are the welding skills?
0Classification by production method
yTrinidadAlloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects， house construction and building decoration. Its fracture will always be found in the production， manufacturing and key marketing of alloy pipe That is，Products Show B steel and steel，التعايش مع البحرأنا الصلب قائمة الأسعارعدة درجات حرارة شائعة الاستخدام with a diameter of -mm. There are certain requirements for pipe tortuosity， so it is flexible.
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 water pressure and flattening tests are carried out.
Bw Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility， gas， air and steam， which is made of hot-rolled steel strip coil as pipe blank， often warm spiral forming and double-sided active submerged arc welding or single-sided welding.
Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility， so it is flexible. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However， there are many types of it. When you buy it， you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next，Products Show Xiaobian will lead you to see the advantages of galvanized pipe.
aIts heat sealing effect is remarkable. It can be directly buried immediately， which can not only save resources， but also reduce consumption， not occupy the natural environment， but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation， prevent actual operation and maintenance， meet the requirements of thermal insulation and cold protection， reduce heating equipment， unique and convenient installation， and reduce the construction cycle time of the project. On the whole，Products Show it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.
VThe production of plastic impregnated welded steel wire mesh is to immerse the formed welded steel wire mesh into a stone groove filled with PVC powder. The dry forming process is complex and the cost is much higher than that of spray welded mesh. Due to different application ranges and different uses， the choice is expensive or cheap，التعايش مع البحرأنا الصلب قائمة الأسعارعدة درجات حرارة شائعة الاستخدام which needs to be determined according to its actual use.
VRecommendation and consultationThey do not need to protect them from mechanical damage.
iCWhat is galvanized pipe
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.
packingo Tungsten; can improve the red hardness and thermal strength of steel， and can improve the wear resistance of steel
FIn order to make the steel pipe workpiece have the required mechanical， physical and chemical properties，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd in addition to the reasonable selection of materials and forming processes， heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore， the heat treatment of steel is the main content of metal heat treatment. In addition， aluminum， copper， magnesium， titanium and their alloys can also change their mechanical， physical and chemical properties through heat treatment to obtain different service properties.
Transformer tube: it is used to make transformer heat dissipation tube and other heat exchangers. It is made of general carbon steel. Flattening， flaring， zigzag and hydraulic tests are required. Steel pipes are delivered in fixed length or double length， and there are certain requirements for the tortuosity of steel pipes.
yLThe 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， and then squeeze it with a steel pipe with an extruder. The efficiency of this method is lower than that of cross rolling method. It is suitable for producing high-strength alloy steel pipe. The billet or ingot must be heated before cross rolling method and extrusion method. The produced steel pipe is called thermal correlation. Steel pipes produced by hot working can sometimes be cold worked as needed. There are two methods of cold working. One is cold drawing. In other words， 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 and improve the mechanical properties of materials.
