What holds grooved pipe couplings together?

Bolted, tri-split metal collar
Bolted, split metallic collar
Welded metal collar
Screwed metal collar

The correct answer is: Bolted, split metallic collar

The correct answer is that bolted split metallic collars hold grooved pipe couplings together. This design utilizes a split collar that wraps around the pipe and is secured with bolts. The split collar allows for quick assembly and disassembly, making it particularly advantageous in various piping systems. The bolted feature ensures a strong and secure connection between the pipes, which is essential for maintaining the integrity of the piping system under pressure and during temperature fluctuations. This method is commonly used in mechanical piping applications, as it facilitates easy installation and maintenance compared to welded connections. Understanding the function of the bolted split collar is important because it directly influences the reliability and efficiency of the pipe system, making it a preferred choice in many industrial and commercial applications.
