What are the requirements for 16Mn seamless steel pipes during production?

Image
  First, the model classification and storage of 16Mn seamless steel pipe However, for different good-quality 16Mn seamless steel pipes( a 106 pipe ), they must be classified and stored, otherwise the 16Mn seamless steel pipe will be quite troublesome during use. However, in order for 16Mn seamless steel pipes to be quickly found based on the model selection, they must be classified and stored according to their different models when they are stored in the warehouse, and their models need to be recorded when they are classified and stored. It is clear that when 16Mn seamless steel pipes are selected, the time to use 16Mn seamless steel pipes will be reduced. Second, a good storage environment: However, when storing 16Mn seamless steel pipes( astm sa106 ), pay attention to keeping the environment clean. If the warehouse is too messy, you need to clean up the warehouse, and then store the 16Mn seamless steel pipes, and the requirements for the warehouse need to be able to ventilate and c

What problems should be paid attention to when welding 16Mn seamless steel pipes?

Image
   The process of 16Mn seamless steel pipe processing is a more important step, and in many cases it is a series of complete steps. Because 16Mn seamless steel pipe is a useful type of steel, there are many production technologies that we need to master. One of the more important technologies is welding, because electric welding is indeed a difficult technical activity. It is generally necessary to pay attention to the relevant technology when it is time. The relevant technology and steps are stipulated as follows. We write it down for your reference only: (1) Check whether the water, electricity, and gas are connected, and connect them as required, and they cannot be loosened. Water, electricity, and gas are all dangerous factors in the welding process of special-shaped pipes, so they must be checked before welding. (2) Use related tools to clean the profile of the base material, that is, use a brush or sandpaper to completely cut the base material profile water, oil, oxides and othe

What are the test methods and procedures for flattening seamless steel pipes?

Image
 The process of making seamless steel pipes ( ASTM A106 GR.B ) is relatively cumbersome and rigorous. After the seamless steel pipe is produced, certain tests must be carried out. Do you know the method and procedure of the flattening test of seamless steel pipe? flatten the sample 1. The sample is cut from any part of the seamless steel pipe that has passed the visual inspection. The sample should be the full-loaded pipe section of the pipe product. 2. The length of the sample should not be less than 10mm, but not more than 100mm. The edge of the sample is allowed to be rounded or chamfered with a file or other methods. If the test result meets the test requirements, the edges of the sample may not be rounded or chamfered. 3. If you want to do it at the end of a full-length tube. During the test, the cut is perpendicular to the longitudinal axis of the tube at the length of the sample from the end of the tube, and the cutting depth is at least 80% of the outer diameter.

How to connect two seamless steel pipes?

Image
  There are many ways to connect two seamless steel pipes (eg: ASTM A106 steel pipe ) together, but generally speaking, there are two major ways: one is detachable connection, the other is non detachable connection. Detachable connection refers to the removal after installation. Non detachable connection is to connect two seamless steel pipes together forever. The most commonly used method of non detachable connection is welding. Two seamless steel pipes are welded together by various welding methods. This method costs less, but it requires higher working environment. If the pipe is too long or the diameter is too large, it is not convenient to work after welding together.   The most commonly used detachable connections are   1 . Flange connection (easy assembly and disassembly, strong versatility).   2 . Union connection (Union is divided into thread type and welding type)   3 . Special pipe joint connection (internal thread, external thread and other forms).   Users can choose the sp

What are the advantages of using longitudinally welded pipes to transport fluids?

Image
  At present, the proportion of oil and gas transported by longitudinally welded pipes (eg: ERW steel pipe )  in the world is increasing, accounting for about 75%-95% of the total oil and gas.The scope of transportation is gradually expanding, not only petroleum and natural gas, but also various chemical industries. Raw materials and products, and the use of longitudinally welded pipes to transport solids has been studied. The development direction of longitudinally welded pipe pipeline transportation points to the direction of large diameter and high pressure.   The use of longitudinally welded pipes to transport fluids has the following advantages   1. The cost of infrastructure is low. Compared with railway transportation, the cost of infrastructure can be saved by one third, and the transportation volume is twice that of railway.    2. Simple construction, fast construction speed, generally laid underground, safe and reliable, and adapt to various terrains.    3. The transportation

Research and development of Chinese standard and American ASTM standard cryogenic seamless pipe

Image
  Low-temperature seamless steel pipes are mainly used in the production of ethylene, propylene, urea, synthetic ammonia, compound fertilizers, and other process equipment such as washing, purification, desulfurization, and degreasing in the pharmaceutical industry, as well as cryogenic equipment manufacturing, ultra-low temperature cold storage, and ultra-low temperature liquefaction. Gas pipelines and their pipe components, such as petroleum gas cryogenic separation equipment, air separation equipment, etc. There are two main types of low-temperature seamless steel pipe materials: austenitic and ferrite. The difference in crystal structure determines that the austenitic cryogenic pipe has no brittle transition temperature in the low temperature range. Generally, it is not necessary to verify its low-temperature impact toughness. It is used, but GB150-2011 stipulates that when the operating temperature is not lower than -196 ℃ (low temperature range), the impact test can be exempted.

The role of thermal insulation steel pipes in converting coal to electricity

Image
  Coal-to-electricity conversion refers to the conversion of coal-fueled boilers and other tools used for heating to electric heating. Under current environmental protection requirements, it can only be changed to clean energy. Coal-to-clean energy accounts for about 80% of the share , It is widely used because of fast electric transmission and fast heating. The heat transfer from coal to electricity is still hot water, so hot water is still used to transport hot water. Insulating steel pipes still play an irreplaceable role in other conveying products in the coal-to-electricity conversion, because the heat loss of insulated steel pipes is very small when transporting the medium. In addition, the insulation steel pipe has a long service life, low cost, high social benefit, and simple construction. The insulation steel pipe also has an alarm line. Once there is water leakage, it will immediately report to the police to deal with hidden dangers in time. The superior performance of the in
