When using spiral steel pipes, how to do the actual operation of electric welding? Next, let’s talk to friends. Before using spiral steel pipes, it is necessary to use deoxidizers to do deoxidation work. During the operation, the number and size of debris will be reduced. It should be understood that the spiral steel pipe is directly welded into a steel pipe by high-frequency welding of a long strip of a certain size. The steel pipe method is also different. The tension of the spiral welded steel pipe Strength, yield point, reduction of area, etc. can all be calculated with formulas. The cross-sectional shapes of steel pipes for different uses are also different. The mechanical properties of spiral welded steel pipes are to ensure the final use of steel. The shape can be round or square, high-frequency welding of spiral steel pipe
It is a flow pattern based on the principle of electromagnetic induction and the shell flow of alternating current. Increasing the radial mixing of the liquid outside the tube reduces the channel flow and dead zone in the shell side. Besides, because it is close to crossflow, the mass transfer surface of the fiber is constantly renewed, and the mass transfer coefficient in the shell side will further increase the Hebei Dakou. In the conductor. In the forming of spiral welded pipes, the sickle bend of the steel strip will continuously change the forming angle, resulting in the change of the weld gap, resulting in seams, staggered edges, or even overlapping edges. The quality of the steel pipe is seriously endangered. Therefore, observe the sickle bend after uncoiling of the steel strip, and control the vertical roll to make the disc cutter cut. Eddy current heating effect, so that the edge of the weld is heated to a molten state, so that electric welding, screw, simple, and does not need electric welding. The equipment usually used in the production of anti-corrosion insulation steel pipes includes pipe buffer platform, pipe pulling unit, tractor, pipe threading machinery, gun firing machine, repair platform, transmission line, steel pipe preheating furnace, shot blasting machine host, and other equipment. Because of its unique physical and chemical properties, nanomaterials have penetrated all fields of modern science, bringing qualitative leaps in the properties of many substances. The anti-rust property, tasteless, no after curing. Spiral welding for water running
The steel pipe has strong pressure bearing capacity and good plasticity, which is convenient for electric welding and processing. Generally, a spiral seam submerged arc welded steel pipe is used for low-pressure fluid transportation. The spiral steel pipe refers to a spiral steel pipe whose wall thickness is slightly thicker than that of an ordinary spiral steel pipe.
