What is the use of glass fiber reinforced plastic sand-filled pipe?

Fiberglass reinforced sand pipes are widely used in industry, mainly because all sand-clad pipes have the characteristics of acid resistance, alkali resistance, and salt resistance. Especially in industrial production, there is a large amount of wastewater that needs to be treated and discharged, so this requirement can be met by using sand-clad pipes made from this material.

What is the correct method for connecting fiberglass reinforced sand pipes?

What is the correct connection method for fiberglass reinforced sand pipes? The correct connection method for fiberglass reinforced sand pipes is as follows: 1) Timely treatment. Fiberglass reinforced sand pipes that have just been removed from the mold cannot be immediately used for bonding and sealing. It is necessary to treat them promptly to remove volatile substances such as styrene monomer produced during the manufacturing process. In addition, timely treatment also helps to release and eliminate the stress in the fiberglass components.

What are the advantages of fiberglass reinforced sand pipes? How to repair them after damage?

What are the advantages of fiberglass reinforced sand pipes? How to repair them after damage? The advantages of fiberglass reinforced sand pipes are as follows: 1. Good corrosion resistance Fiberglass reinforced sand pipes are resistant to acids, alkalis, and soil erosion, and can transport groundwater, seawater, industrial wastewater, and highly corrosive liquids. Special pipe materials are manufactured using appropriate corrosion-resistant materials based on the transported medium, and the sand-filled pipes can maintain all the characteristics of the original fiberglass products (lightweight, high strength, corrosion resistance, insulation, heat insulation, and design).

Causes of Damage to Fiberglass Tanks

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.

Understanding New Composite Materials - Fiberglass

With the rapid development of the national economy, the development direction of various industries has also improved, and the application range of fiberglass reinforced plastic (FRP) has become increasingly broad, beginning to enter various fields. So, what is "fiberglass reinforced plastic"? First, let me give you a brief introduction to the legendary "mysterious fiberglass reinforced plastic." Fiberglass reinforced plastic is neither glass nor steel, but a new type of composite material. It contains fiberglass, resin, and some resin adhesives, making it flexible yet hard, resistant to corrosion, and non-conductive. It is considered one of the best materials on the market in terms of toughness and brittleness. Fiberglass reinforced plastic can mostly be manufactured into various machine parts, and its application fields are mainly suitable for industries such as construction, chemical engineering, transportation, and highway construction. In just a few years, the material of fiberglass reinforced plastic has achieved technological breakthroughs and rapid development, bringing substantial profits and huge business opportunities to many merchants. Next, let's understand the excellent performance of fiberglass reinforced plastic. First, it has extremely high hardness, comparable to steel. This composite material is gradually replacing carbon steel materials such as stainless steel and non-ferrous metals, being both environmentally friendly and hard. Secondly, it has strong corrosion resistance. It contains fiberglass and other reinforcing agents, providing excellent resistance to corrosion and pressure. Additionally, it can be molded in one piece and is very lightweight. Its tensile strength is comparable to that of high-grade alloys, and its flexible texture allows it to be shaped into any form of craft according to product needs, offering high flexibility. Finally, it is non-conductive but has good thermal conductivity. It is considered a good insulating material, capable of preventing burning and heat insulation even at extremely high temperatures. The above is a simple introduction to the new material fiberglass reinforced plastic, and I hope it can be helpful to everyone.

What causes the glass fiber reinforced plastic tank to appear sunken?

Fiberglass tanks are non-metal composite material tanks made from resin and fiberglass, wound by microcomputer-controlled machines. They have advantages such as corrosion resistance, high strength, and long service life. However, fiberglass tanks may also experience a phenomenon known as "suction collapse." What causes this? The shortcomings of fiberglass tanks include insufficient rigidity and high brittleness. The normal service life can reach over 10 years (exposure to sunlight can reduce this lifespan), and they can withstand pressures of up to 10 kg. Improper storage can lead to the rupture of fiberglass tanks, affecting their subsequent use. Generally, the pre-treatment water flow pressure is around 3 kg, and under normal circumstances, they are not prone to rupture. If suction collapse frequently occurs, please check for the following issues: 1. The main reason for the suction collapse of the tank is negative pressure, which can be caused by two factors: ① A high-pressure pump causing the tank to collapse: If the water source is cut off before pre-treatment, and there is no water flowing through the filter, but there is an issue with the electrical control at the back end, or if a low-pressure switch protection is not installed (or the low-pressure switch is ineffective) to cut off the power supply to the reverse osmosis main pump, the pump will draw air due to the lack of water flow, resulting in negative pressure and causing the fiberglass tank to collapse. ② Backflow at the water inlet causing negative pressure that collapses the tank; a check valve should be installed. 2. Insufficient design strength of the wall thickness or defects such as local delamination or non-through channels during the molding process can cause the fiberglass tank to collapse. 3. Lack of protective devices for the reverse osmosis equipment main unit can lead to water hammer phenomena, which refers to the rapid increase or decrease in water flow, velocity, and pressure in a short period within a certain space. These are the reasons for the suction collapse phenomenon in fiberglass tanks. I hope this information is helpful.

What should be noted during the installation of fiberglass reinforced sand pipes? How to deal with sand leakage? Does everyone understand? Installation precautions for fiberglass reinforced sand pipes: 1. When loading and unloading fiberglass reinforced sand pipes, avoid using hard ropes or steel wires for binding. Soft ropes should be used, and do not thread the rope through both ends. 2. Secondly, when the pipes are buried at the construction site, they need to be secured with wooden wedges to ensure that the two pipes do not come into contact.
