Two Rust Removal Methods of Polyurethane Thermal Insulation Pipe
The mother pipe of polyurethane insulating steel pipe will show a long embroidery because it is temporarily exposed in the air. It will also affect the anticorrosion and service life of the insulating steel pipe. So how to stop the rust prevention of the insulating steel pipe? Here we introduce two rare methods of rust removal.
Shot peening disposal technology is to use air and high pressure water flow through a common nozzle to make Abrasives move at high speed, impact and friction. By this way, rust, oxide scale, purifiers and adhesives on the surface of steel can be removed. At that time, the steel will not change color, and it will constitute a suitable cleanliness and roughness. For boilers and petrochemical machinery enterprises with large steel consumption, shot blasting technology is usually used. Under the action of high-speed rotating blades, abrasives are thrown to the steel surface by means of large radial and tangential velocities, so as to achieve the purpose of removing impurities.
The heat preservation pipe with different diameters is used when the pressure of the back section of the pipeline is added in the process of long interval steam transmission. It can also stop welding when the diameter of the pipeline and pipeline changes.
Fixed bracket, each compensation section must exist, not short of accessories, play the role of fixing compensator, connecting the straight pipe section.
The compensator can compensate the thermal expansion and cold contraction of the pipeline, prevent the expansion of the pipeline from occurring weld opening and pipe deformation.
The trap can reasonably remove the condensate water in the pipeline and prevent the pipeline pressure from rising.
The function of the tidal pipe is to sweep the moisture in the insulation layer space and prevent the pipeline from exploding. A qualified pipeline is inseparable from the quantity, length, direction, pressure and astronomical environment of insulation pipe fittings.
