1.1 General Information GRP manholes and chambers are made of FLOWTITE GRP pipes as integral part of pipe installations. Their design is based on FLOWTITE GRP pipes and GRP plates, joined together with the use of polyester – glass fibre laminates. The technology used in the productionprocess of GRP manholes and chambers guarantees that they are completely sealed, fully corrosion proof, have excellent durability and can be safely serviced and maintained. Manholes and chambers are monolithic products with defined composition and properties. 1.2 Purpose Manholes and chambers form a part of underground gravitational and pressure systems, allowing for the inspection and operation of pipelines and fittings, as well as for changing the flow conditions of a medium, within the range of their intended use. · GRP manholes and chambers are primarily designed to be used for: · inspection and maintenance of drains or sewers · ventilation of drains or sewers · flow conditions change of a medium(change of direction, change of pressure, change of water flow rate) · cleaning and flushing of drains or sewers · maintenance of water meters and fittings · housing of pumping stations · inlet drain pits 1.3 Features & Benefits FLOWTITE GRP manholes consist of a composition of high tech materials and offer many features and benefits: Non-corrosive Durable Safe Maintenance-free Internal and external corrosion resistance One-piece wall structure Restricts infiltration Avoids exfiltration Lightweight Easy handling Unloading with light equipment No heavy equipment necessary for installation Easy installation Savings in installation time Smaller excavation No heavy footings No waiting time for curing of the base plate before installation Easy fabrication: additional pipe entries can be cut with standard power tools No assembling on site Minor grouting necessary Easy inspection Reliable product Dependable Dimensionally stable Uniform design download GRP
