   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

 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.
