In the complicated environment, you can choose different Corrosion-resistant pipes according to the requirements of media.  According to the pressure of process requirements, design, manufacture pipes and fittings. And use 1.5 multiples pressure of the process requires to charge pressure test heat. And the low temperature is minus 70 degrees, high temperature is 250 degrees.The insulation performance is good, can eliminate static electricity after improvement. It will not be spontaneous combustion, other way, it can refuse burning good performance, it also can be self-extinguishing.Good transparent performance, it can be in a variety of colors after improvements.The thermal conductivity can be improved after reform.
