Connection and use of glass pipelines
Thread Content
1. For glass fiber reinforced plastic pipelines, is it possible to make openings on-site in order to connect the sewage and vent valves? 2. How can leaks be reduced when glass fiber reinforced plastic pipelines are laid underground?
No, there are already finished tee fittings available; burying them is complicated, and ground preparation is also difficult. This is likely an oil and gas processing project in the Middle East.
It’s a problem – the pipes on site don’t come equipped with dedicated tees, making it difficult to handle waste discharge and venting
It’s not a composite pipe, right? It’s indeed difficult to handle. You should consult the manufacturer right away; they have solutions.
Whether it is FRP or FRP/PVC, a tee can be installed on-site; however, it is necessary to ensure the quality of the area where the tee is installed. If it is to be buried, it is best to do so after pressure testing is completed; sand should be placed at the bottom of the pipe, surrounding it, and the top should also be covered with sand. Otherwise, it’s easy to get damaged.
Holes can be drilled; use the manufacturer’s specialized products and follow the installation instructions or the manufacturer’s guidance.
Holes can be drilled on-site; the main pipe and branch pipes are then bonded together using fiberglass, resin, and curing agent, after which 24 hours are needed for curing. Burying it reduces leaks; that is, minimizing the connection seams, and using longer prefabricated pipes
