Desulfurization tower pipeline fittings-河北三阳盛业玻璃钢集团有限公司

Desulfurization tower pipeline fittings

The fiberglass spray pipe fittings used in flue gas desulfurization engineering are usually manufactured in sections and parts for ease of transportation during the manufacturing process. When installed on site, the various parts are connected using a winding and bonding process. At present, the connection between the slurry nozzle and the fiberglass spray pipe is basically changed from the previous flange connection to the connection using winding bonding technology. The winding bonding process has the advantages of high connection strength, low leakage, simple process, convenient construction, and low cost.

1、 The fiberglass spray pipe fittings used in flue gas desulfurization engineering are usually manufactured in sections and parts for ease of transportation during the manufacturing process. When installed on site, the various parts are connected using a winding and bonding process. At present, the connection between the slurry nozzle and the fiberglass spray pipe is basically changed from the previous flange connection to the connection using winding bonding technology. The winding bonding process has the advantages of high connection strength, low leakage, simple process, convenient construction, and low cost.
2、 The desulfurization spray pipeline is divided into three parts from the outside and inside:
1. Wear-resistant layer of fiberglass spray pipe: This part belongs to the outer structure of the winding layer, composed of fiberglass surface felt, resin, and silicon carbide, mainly used for corrosion resistance and wear resistance.
2. Corrosion resistant layer of fiberglass spray pipe: This part is composed of a secondary resin layer and an intermediate layer, composed of fiberglass surface felt and resin, forming high corrosion resistance and located below the wear-resistant layer. The resin rich layer has a resin content greater than 90% and a thickness of approximately 0.5mm; The middle layer has a resin content of 70% to 80% and a thickness of approximately 2.0mm.
3. Reinforced layer of fiberglass spray pipe: This part is directly wrapped on the outer wall of the pipeline and is mainly designed to withstand pressure and other loads. Its thickness is calculated and determined according to equation (1) according to the load conditions. This layer has a resin content of 30-40% and is composed of glass fiber, chopped fiber felt, and resin.
3、 After the winding and bonding construction of the winding layer is completed, the winding layer should be inspected in accordance with the requirements of HG/T20696-1999 "Design Regulations for Glass Fiber Reinforced Plastic Chemical Equipment". It is qualified if there are no delamination, delamination, cracks, cracks, fiber exposure, dry spots, inclusions, bubbles, small holes, resin tumors, and other defects.

FRP septic tank

Septic tank refers to the equipment made of synthetic resin matrix and glass fiber reinforced material, which is specially used to treat domestic sewage. It is mainly applicable to domestic sewage purification treatment equipment for civil buildings such as industrial enterprise living quarters and urban residential quarters. The tank body is made of glass fiber reinforced plastic material by molding or winding process, with high strength and good sealing performance. It will never be broken or damaged due to foundation settlement and the phenomenon of hardened scum layer in the tank will never occur, which completely solves the problem of brick septic tank polluting groundwater.

FRP septic tank

The basic principle of FRP moulded septic tank, wound septic tank and internally reinforced septic tank is to remove and kill parasitic eggs and bacteria, control the breeding of mosquitoes and flies, and achieve the goal of harmless fecal disposal by using the sedimentation of parasitic eggs, which is more important than the feces and urine mixture, and the principle of closed anaerobic fermentation, liquefaction, ammoniation, and biological antagonism.

Glass fiber reinforced plastic power protection tube

Fiberglass cable protection tube, cable threading tube - is a type of pipe formed using unsaturated polyester resin as the matrix, continuous glass fiber and its fabric as the reinforcing material, and computer-controlled winding or extrusion process. The fiberglass cable protection tube is currently used more frequently in line laying, with obvious advantages such as high strength and corrosion resistance, and the inner wall of the cable is smooth and scratch free.

Urban rainwater drainage pipeline

Fiberglass reinforced plastic pipes are lightweight, high-strength, and corrosion-resistant non-metallic pipes. It is made of resin (food grade resin is used for conveying drinking water), glass fiber, quartz sand and special process. It uses resin as the matrix and glass fiber as the winding layer by layer on the rotating core mold according to the process requirements, and evenly lays quartz sand between the fibers as the sand layer. Its pipe wall structure is reasonable and advanced, which can fully utilize the role of materials, improve the rigidity while meeting the requirements of service strength, and ensure the stability and reliability of the product.

Buried sand pipe

GRP buried sand pipe is a new composite material made of resin as the matrix material, glass fiber as the reinforcement material, and quartz sand as the filling material. It has become the best choice for the chemical industry, drainage engineering, and pipeline engineering due to its excellent corrosion resistance, hydraulic characteristics, lightweight and high-strength, large transportation flow, convenient installation, short construction period, and low comprehensive investment.

Fiberglass cover plate

The anti odor cover plate of fiberglass sewage tank is mainly used in sewage treatment system engineering, petrochemical and other industries. Due to the characteristics of corrosion resistance, lightweight and high-strength, aging resistance, designability, easy installation, and long service life of fiberglass, fiberglass cover plates have been widely used in the development of modern society. According to user requirements and the size of the sewage tank, other shapes such as curved cover plates and flat cover plates can be made. Its colors can also be made into various colors according to the needs of users, to meet their different needs.
