FRP process pipeline: FRP process pipeline enjoys the reputation of "significant energy saving", which is characterized by n≤0.0084 - due to the smooth inner wall, its fluid conveying head loss is small, so the same flow rate can be selected smaller Pipe diameter or smaller power delivery pumps - used for long-distance transportation, large-diameter pipes can also reduce installation costs, reduce heat preservation costs, cancel anti-corrosion costs, and exempt overhaul costs - a good deed of "extending longevity". FRP process pipelines are frozen. Under the medium, the pipeline will not be frozen and cracked. FRP process pipeline is corrosion-resistant: in a criss-crossed and scattered environment, different corrosion-resistant pipelines can be selected according to the requirements of the medium FRP process pipeline pressure: according to the pressure required by the process, design and manufacture pipelines and pipe fittings. Charge pressure test at 1.5 times the pressure required by the process - heat resistance: low temperature resistance is negative 70 ℃, high temperature resistance is 250 ℃, FRP process pipeline has good insulation performance and can eliminate static electricity after improvement; good flammability and improvement can be automatically Extinguishing, flame retardant, flame retardant; good transparency and improved can be colorful; thermal insulation performance and improved can improve thermal conductivity FRP process pipes are non-toxic: can be used for the delivery of drinking water FRP pipes have many advantages such as strong corrosion resistance, smooth inner surface, low transmission energy consumption, long service life (over 50 years), convenient transportation and installation, no maintenance and low comprehensive cost. It has been widely used in chemical industry, papermaking, urban water supply and drainage, factory sewage treatment, seawater desalination, gas transportation and other industries.
Quartz sand-incorporated pipeline - that is, quartz sand fiber winding FRP pipeline, that is, in the fiber winding process, the quartz sand is sandwiched into it with a reinforcing layer, so that it has a sandwich structure, which reduces the FRP pipeline of the pipeline. The overall cost of construction and the overall stiffness and strength of the pipeline are improved. The laminated structure of quartz sand-filled pipeline consists of four parts: inner lining layer, transition layer, structural layer and outer surface layer.
Characteristics of quartz sand-incorporated pipes:
FRP pipes (1) Corrosion resistance: chemically inert material with excellent corrosion resistance, and different corrosion-resistant pipes can be selected according to the conveying medium.
FRP pipes (2) High mechanical strength: good water pressure resistance, external pressure resistance and impact resistance, and pipes and fittings can be designed and manufactured according to the required pressure.
FRP pipe (3) Strong temperature adaptability: Operating temperature range: greater than -70 degrees Celsius and less than 250 degrees Celsius, the pipeline will not crack under freezing medium.
FRP pipe (4) Small fluid resistance: the inner wall of the pipe is smooth, and the roughness coefficient is 0.0084. Under the same flow rate, the pipe diameter can be reduced.
FRP pipe (5) is light in weight and long in service life: light in weight, convenient in transportation, low in construction cost, no maintenance required, and has a service life of more than 50 years.
GRP pipeline (6) to maintain water quality: non-toxic, transport drinking water, and can maintain long-term water quality hygiene.
