Causes of Damage to Fiberglass Tanks
Release time:
2023/04/17
Fiberglass tanks have advantages such as corrosion resistance, high strength, long service life, flexible design, and strong processability. Due to the characteristics of fiberglass tanks, they are widely used in industries such as chemical, environmental protection, food, pharmaceuticals, and dyeing, gradually replacing carbon steel and stainless steel in most market areas. Although fiberglass tanks have a long service life, they can also be damaged. Below are the reasons for the damage to fiberglass tanks: 1. Cracking and leakage of the plastic laminate occur due to exceeding design conditions, such as overpressure, exceeding vacuum limits, and vibrations, especially from steam jet heaters. 2. Care should be taken to prevent overpressure in fiberglass tanks; a typical form of circumferential stress failure in pipeline systems is longitudinal cracking, while in vertical storage tanks, it is vertical cracking. 3. Chemical erosion of the laminate can take many forms, such as solvent action and dehydration. 4. Severe exothermic reactions should be prevented inside the tank, as they can cause significant damage to fiberglass tanks. Many systems that produce such reactions are designed with sloping or cooling devices to withstand large amounts of heat release. 5. Damage to the pipe openings may be due to improper design or inadequate support; care should be taken with the pipe openings of fiberglass tanks, and they should be used only for heavy loads. It is also recommended to specify and use short connecting pipes with a pressure rating of at least 100 pounds per cubic inch, reinforced with angle brackets. 6. Poor grounding of fiberglass tanks can cause severe damage, even leading to the collapse of the dome top; the dome top is the weak point of any fiberglass tank, which can be theoretically proven from subjective design formulas and has been confirmed by practice, regardless of whether the tank is fiberglass or metal. 7. All fiberglass tanks and containers should be checked for cracks after shipping; if the tank body is not properly supported, it may occur. Due to improper handling methods, there have been incidents where large cracks appeared between the tank body and the tank head. These are the reasons for the damage to fiberglass tanks, and I hope this information is helpful to everyone. Guangxi Fiberglass Products Co., Ltd. is a professional manufacturer of fiberglass products, and our products are well received by users. We welcome inquiries.
FRP tanks have advantages such as corrosion resistance, high strength, long service life, flexible design, and strong processability. Due to the characteristics of FRP tanks, they are widely used in industries such as chemical, environmental protection, food, pharmaceuticals, and dyeing, gradually replacing carbon steel and stainless steel in most market areas. Although FRP tanks have a long service life,butthey can also be damaged,Nextlet's introduce the reasons for the damage to FRP tanks.:
- Cracking and leakage of the plastic laminate are due to exceeding design conditions, such as overpressure, exceeding vacuum limits, and vibrations, especially from steam jet heaters.
- Care should be taken to prevent overpressure in FRP tanks; the typical form of circumferential stress failure in pipeline systems is longitudinal cracking, while in vertical storage tanks, it is vertical cracking.
- Chemical erosion of the laminate can take many forms, such as solvent action and dehydration.
- Severe exothermic reactions should be prevented inside the tank, as this can cause significant damage to the FRP tank. Many systems that produce such reactions are designed with inclined or cooling devices to withstand large amounts of heat.
- Damage to the pipe openings may be due to improper design or inadequate support; do not be careless with the pipe openings of FRP tanks, and ensure they are used for heavy loads in a timely manner, specifying and using short connecting pipes with a pressure rating of at least100 pounds per square inch, and reinforced with angle brackets.
- Poor grounding of FRP tanks can cause severe damage, even causing the dome of the tank to collapse. The dome is the weak point of any FRP tank, which can be theoretically proven from subjective design formulas and has been confirmed by practice, regardless of whether the tank is an FRP tank or a metal tank.
- All FRP tanks and containers should be checked for cracks after shipping. If the tank body is not properly supported, this may occur; due to improper handling methods, there have been incidents of large cracks appearing between the tank body and the tank head.
The above are the reasons for the damage to FRP tanks, hoping to be helpful to everyone. Guangxi FRP Products Co., Ltd. is a professional manufacturer of FRPproducts.The products are well received by users, and you are welcome to call for consultation.
