玻璃钢罐损坏有哪些形式和原因呢？

1、要谨防玻璃钢罐超压；周应力破坏的典型形式在路管中是纵向开裂，在立式贮罐中则是垂直开裂。

2、塑料层压物的开裂和漏泄是由于超过了设计条件，例如超压、超过真空限度、震动，来自蒸汽喷射加热器的震动。

3、层压物的化学侵蚀可以有许多形式，例如溶剂作用和脱水等。

4、管口的损坏可能由于不正确的设计或不适合的支撑；对玻璃钢罐的管口不要马虎，及时只用于重载荷，也应规定并使用至少为100磅/寸立方表压的短接管，而且用角撑板加固。

5、玻璃钢罐和容器在发货装运后，应该检查有无裂缝，如果罐体没有支撑好是可能发生的；由于不适合的搬运方式，曾经发生过罐体与罐头之间出现大裂缝的事故。

6、要防止在罐内发生严重放热反应，这可以造成玻璃钢罐的严重损坏，许多生产这种反应的系统都设计了倾斜或冷却装置以抵御大量放热。

7、接地不好的玻璃钢罐会引起严重的破坏，甚至会把盘形罐顶大貂，盘形罐顶是玻璃钢罐的薄弱环节，这可以从主观设计公式的理论上证明，并且已被实践证实，不管贮罐是玻璃钢罐或是金属罐的都一样。

What are the forms and causes of damage to frp tanks? 1. Beware of overpressure of frp tanks; the typical form of circumferential stress failure is longitudinal cracking in road pipes and vertical cracking in vertical tanks. 2. Plastic laminates crack and leak due to excessive design conditions such as overpressure, over vacuum limit, vibration, vibration from steam jet heaters. 3. Chemical erosion of laminates can take many forms, such as solvent action and dehydration. 4. Damage to the nozzle may be due to incorrect design or unsuitable support; do not carelessly apply to the nozzle of a FRP tank for heavy loads only in time, and require and use a short nozzle with a minimum of 100 PSI cubed gauge pressure, and reinforced with gussets. 5. GRP tanks and containers should be checked for cracks after shipment, which may occur if the tank is not properly supported; large cracks have occurred between the tank and the can due to improper handling. 6. To prevent a severe exothermic reaction in the tank, which can result in severe damage to the FRP tank, many systems that produce this reaction have been designed with tilt or cooling devices to resist large amounts of exothermic heat. 7. Poorly grounded frp cans can cause serious damage and can even lead to large ferrets with plate top, which is a weak link in frp cans. This can be proved theoretically by subjective design formulas and has been proven in practice, it doesn't matter if the tank is made of fiberglass or metal.
