Safe and effective installation of insulation joints is very important, after the installation is necessary to ensure safety, but also to ensure life. Installation Please note the following eight: 1, insulation joints installed within 50m steel insulated joints at the price, do not allow the dead to be welded mouth. 2, insulation joints installed within 200m of the pipeline have died mouth, the mouth of his death should be appropriate welding at a local daily average temperature (± 5 ℃) inside. 3, the insulation joints and plumbing connections are not allowed within 5m lifting the pipeline in order to avoid damage to the insulation joints. 4, insulation joints installed in the gas medium pipeline, buried pipelines shall not be installed in low-lying areas. 5, buck-boost speed of not more than 0.5MPa insulated joints per minute. 6, after the insulation joints and pipe connections shall require mending pipeline corrosion, insulation joints are not allowed to make the surface temperature is higher than 100 ℃, corrosion jobs. 7, only to do before installing insulation performance testing (shake table with 500V resistance should be greater than 2MΩ not less than labeled data 16Mn insulating joints suppliers, should no longer pressure test). 8, insulation joints shall not be used as compensation for thermal stress and deformation pieces. China good pipe insulation fittings manufacturers, all in Hebei billion gold Pipeline Limited. Forming a surface film insulating joints are actually used industrial metal corrosion insulation joints at all, and these are made of solid surface film of corrosion products formed. The protective effect of the surface film is essential that they should be of sufficient thickness and uniformity, can withstand the transfer reaction between the metal and the media. In the iron-based metal and many other metals, the electronic conductivity of the surface film is much higher than the ionic conductivity. Thus, a redox reaction cathodic limit transfer received much less restrictions than the metal ions. A cathodic reaction occurs is not only the site of the metal and dielectric interface, but also the mask table and the medium interface, again, the reaction product formed on the film surface OH-, and the PH value of the medium increases. For most metals, which will reduce the solubility of the surface film. The reaction led to two non-covered on said metal surface area. Such coverage area depending on the presence or absence of the metal surface is substantially the formation of corrosion products, or, depending on the beginning of the medium from a distance whether the formation of a solid oxide. Depending on the circumstances involved in each part of the reaction can answer this question. Ja represents a metal ion forming rate, Jx is involved in the transfer rate of the reaction components, which leads to the formation of the surface film. When Ja> Jx, the precipitation occurs in the medium. In a high concentration of OH-ions in an alkaline medium passive better, because most metal hydroxide has low solubility of carbon steel insulated joint price, insulation joints, welcome to Hebei million gold piping supplied by Hebei billion gold piping.
