  Key Features of Slotted Casing

  Grooved casing is a pipe component made using a special cutting method on petroleum or oil pipes. The production process usually involves cutting longitudinal or spiral straight or staggered slits of a certain specification, using special ultra-thin cutting blades and beam cutting technology to make the slit width of the slotted sleeve between 0.2 and 0.5 mm.

  Analysis of the advantages and disadvantages of different types of flanges

  Flange is a mechanical connection device, usually consisting of two circular metal plates, which are tightly connected together by bolts. Flange is called flange plate or flange by a few people. It refers to the connecting parts that are connected by bolts on two planes at the periphery, that is, the parts that connect the shafts to each other. It is also an important connection method in pipeline construction.
