Handling Matters Of Ductile Iron Pipe Fittings

The air tightness monitoring of ductile iron pipe fittings is a process in the production and use of ductile iron pipes, and it is also the product quality. The detection of gas leakage in an important process of production includes leakage detection of toxic gases, leakage detection of combustible gases and air tightness detection. Most of the first two can be detected by chemical sensors, usually during the use of components or systems. The method is relatively simple if there are suitable sensors.

Ductile iron pipes are protected by 180-degree plain concrete walls. The air tightness test needs to cover the cast iron pipe with soil. If there is leakage, it is necessary to clean the soil and break the plain concrete and other tedious work, which will inevitably affect the progress of the project.

How to use the cold welding material for ductile iron pipe fittings: First, the surface to be repaired must be treated, and there must be no rust and oil, otherwise the adhesive layer will fall off. It is good to roughen it, which can increase the bonding force between molecules. , to enhance the service life of the repaired product. Also remember to choose the cold welding material corresponding to the material of the ductile iron pipe casting itself. For example, the ductile iron pipe casting iron should choose (Jinsucheng) JS902 iron refrigeration welding material, and steel, aluminum, copper, etc. should also choose their Cold welding material, has achieved good repair effect.
