Key Points for Butt Weld Fittings Selection

Butt weld fittings are accessories that connect pipes to pipes or pipes to other equipment through welding. When designing the pipe layout, it is necessary to consider space limitations and the maintenance of the pipe system. Based on the space limitations on site, determine the direction and arrangement of the pipes to make the best use of available space. Besides, consider follow-up maintenance and operational needs, and arrange the pipe layout in a way that is easy for inspection, cleaning, and operation. It is important to be familiar with the functions of pipe fittings and install the pipe system properly.
