What are the two methods of jointing? ?

The two methods of jointing are mechanical jointing and fusion jointing.

1. Mechanical jointing involves using mechanical fittings, such as couplings, flanges, or compression fittings, to connect pipes together. These fittings are typically made of materials like metal or plastic and are designed to create a secure and leak-proof connection between pipes.

2. Fusion jointing involves using heat to melt the ends of the pipes and then pressing them together to create a strong bond. This method is commonly used for joining plastic pipes, such as polyethylene or polypropylene, and can create a seamless and leak-proof connection. Fusion jointing is often used in applications where a high level of integrity and reliability is required.
