Manufacturing process description：
GRP pipes are manufactured using the continuous advancing mandrel process which represents the state of the art in GRP pipe production.This process allows the use of continuous glass fibre reinforcements in the circumferential direction. For a pressure pipe or buried conduit the principle stress is in the circumferential direction, thus incorporating continuous reinforcements in this direction yields a higher performing product at lower cost. Using technology developed by material specialists, a very compressed laminate is created that maximizes the contribution from the three basic raw materials. Both continuous glass fibre roving and choppable roving are incorporated for high hoop strength and axial reinforcement. A sand fortifier is used to provide increased stiffness by adding extra thickness, placed near the neutral axis in the core. With the FLOWTITE dual resin delivery system, the equipment has the capability of applying a special inner resin liner for severely corrosive applications while utilising a standard type resin for the structural and outer portion of the laminate.
Product Benefits
Superior Hydraulic Characteristics:
-Extremely Smooth Bore
-Hazen Williams flow coefficient of approximately C=150
-Low friction means less pumping energy needed and lower operating costs
-Manning's flow coefficient n = 0.009
-Minimal slime build-up means lower cleaning costs
-Excellent abrasion resistance
Performance Standards
LianZhong Fibreglass pipe systems are certified according to many national and international standards.Standards developed by ASTM, AWWA and the last ISO and EN are applied to a variety of fibreglass pipe applications, including conveyance of sanitary sewage, water and industrial waste. A thread common to all of the product standards is that they are all performance based documents. This means that the required performance and testing of the pipe is specified.
