GRP pipe seals are used to join two GRP pipes together. They are made of a variety of materials, including rubber, plastic, and elastomers. The type of seal used depends on the application and the specific requirements of the project.

GRP pipe seals are typically used in the following applications:

• Water transmission and distribution (potable and raw water)
• Sanitary sewerage collection and outfalls
• Storm sewers and drainage
• Seawater intake, outfalls and cooling water lines
• Industrial effluents

The benefits of using GRP pipe seals include:

• Tight, efficient joints designed to eliminate infiltration and exfiltration
• Ease of joining, reducing installation time
• Accommodates small changes in line direction without fittings, or differential settlement
• Long lifespan and resistance to corrosion and abrasion

The different types of GRP pipe seals include:

• Compression seals: These seals are made of a flexible material that is compressed when the pipes are joined. They are a common type of seal and are relatively inexpensive.
• Mechanical seals: These seals use a metal or plastic gasket to create a watertight seal. They are more expensive than compression seals, but they are also more durable and can withstand higher pressures.
• Elastomeric seals: These seals are made of a rubber or plastic material that is molded to the shape of the pipe. They are a good choice for applications where there is a risk of vibration or movement.

The selection of the right GRP pipe seal depends on the specific application and the requirements of the project. It is important to consult with a qualified engineer to ensure that the correct seal is selected.

Here are some of the factors to consider when selecting a GRP pipe seal:

• The type of fluid that will be transported through the pipe
• The pressure and temperature of the fluid
• The size and diameter of the pipe
• The environmental conditions where the pipe will be installed
• The budget for the project
