Corrosion resistance of unsaturated polyester resin Clause description
1.1 Overview
The FRP chemical equipment (or glass fiber reinforced plastic chemical equipment) described in this design regulation refers to the integral corrosion-resistant FRP chemical equipment with thermosetting resin as the matrix material and glass fiber as the reinforcing material. 1.2 Scope of application
This design regulation is applicable to non-movable integral corrosion-resistant FRP chemical equipment made by mechanical winding molding process.
1.3 Inapplicable scope
Equipment heated by direct flame:
Equipment containing extremely hazardous media;
Equipment for heat conduction (such as jacketed reactors, etc.): Special chemical equipment (such as tank cars, electrostatic precipitators, etc.). The classification of extremely hazardous media should be in accordance with the standard HG20660-1991 "Classification of Toxicity Hazards and Explosion Hazards of Chemical Media in Pressure Vessels".
Design pressure
This design stipulates that the design pressure is not more than 0.6MPa, and the external pressure design pressure is not more than 0.1MPaa
Vacuum equipment is designed as an external pressure vessel, and its design pressure is 0.1MPa. 1.5
Design temperature
The design temperature range specified in this design is generally: general unsaturated poly FRP
bisphenol A type unsaturated polyester FRP
vinyl ester unsaturated polyester FRP
epoxy FRP
-40 +60℃
-40 -- + 100℃
- 40- + 120℃
- 40～ +90℃
The corrosion resistance and temperature resistance of various types and grades of resins are different. When designing, the corresponding resin, auxiliary materials and glass fiber should be selected according to the type of corrosive medium and the conditions of use, and a reasonable construction process should be formulated to produce corrosion-resistant FRP chemical equipment. When corrosion-resistant FRP chemical equipment is used under flammable and explosive conditions, the corresponding resin formula and process should be carefully and reasonably selected, and small sample specimens should be made to test relevant indicators. Only after passing the test can it be formally produced.
