PIC has made different developments in GRP piping / coupling joint designs and processes for continuous and centrifugal cast manufacturing processes. The new pipe design and process is now available to authorized users for continuous filament winding process on the Internet. The user (based on his location and current raw material unit cost) can now get the optimized raw material quantities (BOM) for each pipe class (Diameter “DN”, Pressure Rating “PN”, Stiffness Class “SN or STIS”, and Pipe Series “Liner Type, Production Length per Rotation) for the subject GRP project during the quotation stage based on the new developed design and process. Once the order is obtained, the user can get the detailed manufacturing process for any of the subject project pipe classes.
Any non-standard size, pressure class and stiffness class can be requested and sent to the authorized user.
The new optimized design and process is available for different machine types, different unit production rates per rotation and for different types and thicknesses of pipe liners.
The pipe diameter range from 300 to 4000 mm, pressure class up to 32 bar and standards stiffness classes are covered. Any combination of standard or non-standard classes can be provided.Two additional services can also be provided. The 1st is a prerequisite to use the new process and the 2nd is an optional or required depending on the manufacturer level of knowledge and expertise of his production engineers and crews. These are:
IDENTIFYING & VERIFYING "FIVE" AREAS OF
(FP 2.1) CONTINUOUS FILAMENT WINDING (CFW) PROCESS IMPROVEMENTS
THAT HAVE POSITIVE COST & PERFORMANCE IMPACTS
DEVELOPING A NEW OPTIMIZED CFW PIPE LAYERS DESIGN & PROCESS
WITH THE NEEDED WINDER MODIFICATIONS
This report summarizing the results of detailed research and testing programs done on Glass Fiber Reinforced Plastic (GRP or FRP) Pipes manufactured using Continuous Filament Winding (CFW) Process in continuation of previous work done on Centrifugal Cast (CC) Process development. In both cases, the main target was to obtain perfect raw material distribution (Chop and Hoop Glass) for each pipe type layer to improve pipe properties.
The results of the R & D program in CFW Process can be summarized as follows:
The results of the above developments and tools are:
