Introduction to Socket Weld Joint
Socket weld joints are a type of pipe connection method. They are widely used in piping systems for their ability to provide a strong and reliable connection. In a socket weld joint, the pipe is inserted into a socket in the fitting, and then the joint is welded around the circumference. This type of joint is suitable for small - diameter pipes and is commonly used in applications where high - pressure and high - temperature resistance are required, such as in the chemical, oil and gas, and power generation industries. Socket weld joints offer advantages like good sealing performance, smooth internal flow path, and relatively easy installation compared to some other types of pipe connections.
