About the way the bending workpiece is connected to the pipe

Under normal circumstances, when we use the pipe bending workpiece, we often need to connect it with the corresponding pipe first. This is mainly to change the direction of the pipe. At present, we can choose different connection modes to ensure the use. Therefore, in the actual use, we need to combine the actual situation to choose the appropriate connection mode.

BL flange company takes you to understand the process of forging flange

BL Flange Company found that the forging process is generally composed of the following steps, that is, selecting billet blanking, heating, forming, and cooling after forging. Forging process methods include free forging, die forging and fetal membrane forging. During production, different forging methods are selected according to the quality of the forgings and the number of production batches.

What are the maintenance methods of PL flanges

PL flanges that have been stored for a long time should be inspected regularly. The exposed processing surfaces should be kept clean, remove dirt, and neatly store them in a ventilated and dry place indoors. It is strictly forbidden to store them in the open air. Always keep the stainless steel elbow dry and ventilated, keep the device clean and tidy, and store it according to the accurate storage method.

PL flange manufacturers take you to understand the sealing form of flanges

PL flange manufacturers forged flanges are invented and produced on the basis of cast steel flanges, and their strength is much higher than that of cast steel flanges. The parts that connect pipes to each other are connected to the pipe ends. Butt welding flange is a type of pipe fitting, which refers to a flange with a neck and a round pipe transition and connected to the pipe by butt welding.

Technical requirements for butt welding flange installation

Butt welding flange is generally made by forging or forging rolling process. When using steel plate or section steel manufacturing, must meet the following requirements: butt welding flange should be ultrasonic inspection, no delamination defects; It should be cut into strips along the rolling direction of steel, and welded into rings by bending, and make the surface of steel ring cylindrical. Steel plate shall not be machined directly into butt welding flanges with neck.
