The two sets of cooling tower glass fiber reinforced plastic components and plastics in your company have been aged to different degrees, and ironware is severely corroded. If they are not repaired in time, it will cause inconvenience to normal operation. The company sent personnel to conduct an on-site inspection of the cooling tower site. After the inspection, the two sides conducted a careful communication. For the specific content of the renovation and repair, our company has fully considered and deployed, and formulated a specific construction plan, as follows:
1. Current status of cooling tower
1.1 The surrounding ventilation towers under the FRP are aging and need to be replaced
1.2 The water distributor and filler in the tower are aging, and the water cannot be circulated normally.
1.3 The motor bracket and ironware are corroded severely, which affects normal operation.
1.4 The cooling water pipe support is severely corroded and needs to be replaced
1.5 The cable tray is severely corroded and needs to be replaced.
1.6 The valve parts need to be anti-corrosive twice. (Equipment rainproof method)
1.7 The external corrosion above the water tower is severe, and the epoxy resin is now a glass shell.
2, transformation content
2.1 Water supply pipe needs to be replaced
2.2PVC new first-level water spray filler needs to be replaced (see photo for details)
2.3 Packing bracket needs cleaning and repair
2.4 Removal and cleaning of old parts
2.5 cooling tower dedicated fan, reducer with 20# lubricating oil
2.6 Ironware derusting and anticorrosion (including lamp holder ironware, tower ironware, pipes) (see photo for details)
2.7 Cable tray replacement. (See photo for details)
2.8 The pipe bracket is replaced with galvanized channel steel (see photo for details)
2.9 The water tank in the tower needs descaling and cleaning
The second epoxy resin construction above the 3.0 water tower.
4. Construction procedure: Component manufacturing (factory production)—removal of old components and overall equipment
5. Construction process control and quality requirements:
5.1 FRP parts are manufactured using high-quality PVC ventilation materials produced by Wuxi Meigao Factory. The outer frame is made of galvanized square steel. The surface of the parts is sprayed with weather-resistant, aging-resistant, and anti-ultraviolet interference gel coat resin. It will not fade and crack after long-term use. .
5.2 The filler material is PVC, which requires excellent plasticity during the mold and pultrusion process without large gaps and impurities.
5.3 The raw material of the filler bracket is Q235 carbon steel. After rust removal, epoxy asphalt paint is painted on both sides for anti-corrosion
5.4 During the process of component manufacturing and on-site equipment, our company will send a supervisor to supervise the whole construction process, and unqualified processes will enter the next process and construction process.
5.5 Quality assurance: The replacement parts of our company are guaranteed to be used for 10 years.
6. Safe and civilized construction
6.1 In order to ensure safe and smooth construction, effective handling is required. The specific methods are as follows;
6.1.1 During the construction period, there is a special person to take charge of safe construction management, to do a good job in construction safety management, to conduct safety education and training for construction personnel, to improve the safety awareness of construction personnel, and to prevent safety accidents.
6.1.2 For high-altitude workers, they should have good physical and psychological quality, no fear of heights, and everyone should take safety protection measures.
6.1.3 Before the construction personnel work, the safety personnel should check the safety equipment, and those who do not meet the specifications are not allowed to work on the job, and strive to achieve a zero accident site.
6.1.4 During the construction period, it is forbidden to bring flammable materials into the construction site, and it is forbidden to smoke on the construction site to prevent fire accidents.
6.1.5 It is necessary for safety management personnel to patrol the construction site every day, carefully check the safety situation, and carefully make safety records.
6.1.6 Civilized construction by construction workers, establish company image, and establish collective concept.
6.1.7 It is necessary for all construction workers to strictly abide by the regulations and disciplines of their units, and it is forbidden to work in violation of laws and disciplines.
6.1.8 To achieve civilized and safe construction, work together to ensure quality and quantity, so that the project can be completed smoothly.
6.2, civilized construction guidelines:
6.2.1 The construction workers are not loud and noisy during the construction process.
6.2.2 Smoking is prohibited on the construction site.
6.2.3 High heels and slippers are prohibited on the construction site.
6.2.4 It is forbidden to defecate at the construction site.
6.2.5 It is forbidden to work during the rest time of surrounding residents
