Underground Fiberglass Large-Diameter Continuous Winding Fiberglass Pipeline Wrapped Around Sewage Pipe and Drainage Pipe Composite Winding Pipe

Product Description

Product Description

The fiberglass continuous winding pipeline adopts an automated continuous winding forming process. The fiber yarn impregnated with resin is controlled by a computer to spiral wound on the core mold and cured at high temperature, achieving uniform pipe wall structure and controllable strength. This product has high strength and lightweight, excellent corrosion resistance (resistant to acid, alkali, salt spray, with a lifespan of over 50 years), excellent hydraulic performance (smooth inner wall to increase flow rate by 10% -15%), and environmental advantages (recyclable, low energy consumption). Its features include flexible customization of pipe diameter (DN100-DN4000) and pressure rating (0.1-2.5MPa), use of socket or flange connection to ensure sealing, and daily maintenance free. Widely used in municipal water supply and drainage, chemical wastewater discharge, and oilfield transportation, the comprehensive cost-effectiveness is significantly better than traditional pipe materials.

Production process

1. Mold preparation
Clean the surface of the mold to ensure smoothness and absence of impurities

2. Production of inner lining layer
Spray resin mixture (including catalyst/promoter) onto the surface of the mold

3. Reinforcement layer wrapping
Microcomputer controlled continuous winding of impregnated fibers, synchronized addition of quartz sand to form a sand layer

4. Curing and molding
Uniform curing of resin through far-infrared or rotary heating

5. Post processing
After hydraulic demolding, repair the pipe mouth and mark it, and conduct a water pressure test at 1.5 times the working pressure
This process combines the advantages of fixed length winding and centrifugal casting, and can achieve continuous production of large-diameter pipelines above DN2000, suitable for scenarios such as water diversion and sewage pressure pipelines

Application

1.Municipal water supply and drainage: construction of urban drinking water/sewage pipeline network, with smooth inner walls to reduce head loss
2.Integrated pipe gallery: preferred for underground pipe network renovation projects as a substitute for cement/steel pipes
3.Petrochemical industry: transporting strong acid and alkali media (pH 2-12), temperature resistant to 150 ºC
4.Power system: power plant circulating water pipeline, high-temperature flue gas emission channel
5.Metallurgical industry: Corrosive gas dust removal and waste liquid treatment pipelines
6.Food: Aseptic grade tubing, compliant with FDA food contact standards
7.Desalination of seawater: Cross sea water pipeline network, resistant to salt spray corrosion with a lifespan of over 30 years
8.Agricultural irrigation: Lightweight farmland water pipes, resistant to soil chemical corrosion
Geothermal Engineering: Special Pipeline for High Temperature Fluid Transportation in Geothermal Wells
