GRP composite materials attain limitless possibilities that benefit several industries. GRP pipes manufacturers are delivering and catering the plumbing and agriculture industry with their range of composite piping solutions. GRP pipes are revealing the advantages of glass reinforced fiber. In this post, manufacturers will explain their potential use and application in aggressive environment of open cooling systems.
Cooling systems are critical components used in several power processing and manufacturing plants. Industries need to maintain these systems and keep them in good working condition. They often encounter issue of corrosion during maintenance. Mitigation of corrosion is both time consuming and costly and unpredictable.
By installing GRP pipes to these systems, manufacturers can minimize the need for maintenance and shift their focus of treatment to heat transfer equipments.
Challenges and remedies
Cooling tower is a heat rejection device or heat transfer unit installed at the facility to eliminate heat from water-cooled systems. The cooled water is later re-circulated and returned into the system. The cooling potential of a wet surface is better than a dry one.
Cooling systems have several kinds of metals like copper, steel, aluminum, and galvanized steel. Galvanizing is the coating of zinc on steel surface used in open loop cooling systems to protect steel from corrosion and its cost-effectiveness. This material offers long lasting life when maintained by following right practice.
PH imbalance is responsible corrosion, if it increases over 8.2, corrosion starts and white rusty layer can be seen. This reveals that the oxidized zinc is no longer eligible to protect the steel and this ultimately affects the lifespan of the metal system.
GRP material offers limitless possibilities and potentially inert to the aggressive environment of cooling systems- TDS, high chlorides, low pH, bacteria, corrosion, bio film, and formulations injected to provide protection to the expensive metal of heat exchange surfaces.
Components installed in the open re-circulating cooling systems are designed and intended with GRP composites –
- Cooling water suction header
- Cooling water discharge header
- Hot water return to CT desk
- Cold water pipe from CT
- Side stream pipes
This ensures benefits in the modern design of cooling tower systems –
- Friction less piping
- Zero anchor blocks in the pipe design
- Zero joints
- Smooth internal surfaces
- No external protection needed
GRP pipes manufacturers are making these pipes more efficient to handle CT systems. You can find the local supplier in your area to source premium GRP pipes at reasonable prices.
