What type of joint is typically used for low-pressure applications?

Soldered joints are particularly well-suited for low-pressure applications due to their ability to create a strong bond at relatively low temperatures. The soldering process involves melting a filler metal, which can flow into the joint between pipes and fittings, providing a leak-proof seal once it cools and solidifies. This method is common in heating, plumbing, and refrigeration applications where the pressures are generally lower.

Compared to other types of joints, soldered joints are less labor-intensive and do not require the high temperatures needed for brazing or welding, making them a practical choice for certain installations. Additionally, the materials used for soldering, such as lead-free solder, can also help to avoid potential contamination in water supply systems.

While brazed joints are stronger and suitable for higher temperatures and pressures, and welded joints provide robust connections for high-strength applications, they are not typically necessary for low-pressure situations. Threaded joints, while convenient for assembly and disassembly, can lead to leaks if not properly sealed, making them less desirable in low-pressure scenarios compared to soldered joints.
