What is used to secure joints in plastic pipe?

• A. Cement
• B. Weld
• C. Heat
• D. Grout

Answer: (A)

Cement is commonly used to secure joints in plastic pipe because it creates a strong bond between the surfaces being joined. The solvent cement works by partially dissolving the surfaces of the plastic pipes, allowing them to fuse together as it cures and solidifies. This process is crucial for ensuring leak-proof connections that can withstand pressure and stress in various piping applications.

The use of cement is particularly important in plumbing and drainage systems, where the integrity of the joints can significantly affect the overall performance of the piping system. It provides a reliable, long-lasting connection that can resist the effects of water, chemicals, and temperature variations.

Other options like welding and heat are not typically employed with plastic pipes, as these methods are more suited for joining metal materials. Grout, on the other hand, is used primarily in masonry and concrete applications and does not provide the necessary bonding for plastic pipe joints.
