The pre-steps of the anti-corrosion tape primer are as follows
The anti-corrosion tape utilizes the strong adhesion of the epoxy powder to the surface of the steel pipe to improve the adhesion; the excellent mechanical strength, chemical stability, insulation, resistance to plant root penetration, water penetration resistance, etc. of the extruded polyethylene are utilized.
NBR nitrile rubber sealing ring: It is suitable for use in petroleum-based hydraulic oil, glycol-based hydraulic oil, diester-based lubricating oil, gasoline, water, silicon grease, silicone oil and other media.
Instead of plastic paper, the sealing film is then compacted and finally assembled for interior trim.
The rubber material has excellent heat resistance, cold resistance, ozone resistance and weather resistance. Has good insulation properties. However, the tensile strength is inferior to that of ordinary rubber and does not have oil resistance.
Exhaust Spiral Wound Gaskets have good compression performance, good resilience, multi-pass seal and certain self-tightening function. They are not sensitive to surface defects on flange compression surfaces.
