Where are metal conduits used for?
It is used in the normal environment of the living room and in the places with high temperature, dust, vibration and fire danger. Can also be used in wet venues. It should not be used in places that are particularly humid, with acid and alkali, salt corrosion and explosion risks. Use the ambient temperature is minus 15 degrees Celsius to 40 degrees Celsius. The threading pipe has good mechanical properties, good corrosion resistance, high compressive strength and working pressure above 2.5 MPa.
The threading pipe has a smooth surface, low fluid resistance, no scaling, and is not easy to produce microorganisms. Small thermal expansion performance, no shrinkage and deformation. The previous placement connection form. In particular, its epoxy plastic coating layer is very effective in dealing with water conveyance, burial and corrosion of metal pipes by acid, alkali and salt, and its service time can reach more than 50 years.
What are the ways to correctly judge the authenticity of metal emt conduit pipes?
1. The content of impurities in the composition of high-quality steel pipes is low, so it will contain a higher rigid density.
2. The section of inferior steel pipe is usually oval.
3. The high-quality steel pipe is very hard and not easy to be scratched.
4. The inner diameter of the high-quality metal threading pipe has not changed greatly.
5. Folding often occurs, which means that it is inferior.
6. If there is a pockmarked surface on the surface of your steel pipe, it means that it is of inferior quality.
7. Of course, if the surface of the steel pipe you purchased is very prone to cracks, it means that the steel pipe is of inferior quality. After all, the blank of this kind of steel pipe is made of adobe. If it encounters thermal stress, it is very prone to cracks.
