Welded pipe fittings have a wide range of applications in industries, construction, automobiles, and other fields. According to different needs and usage conditions, different types of welding fittings can be selected, such as butt joints, T-joints, lap joints, and corner joints. Below, we will provide a detailed introduction to common types of welded pipe fittings and their applications:

1. Butt joint: The common forms of butt joints include four types: flat welding, vertical welding, horizontal welding, and overhead welding. This type of joint is usually used for connecting pipes, and can also be used for connecting socket welded fittings in specific environments such as high-pressure steam equipment, chemical high-temperature and high-pressure pipelines, pressure vessels in power plants and nuclear power plants.

2. T-joint: This type of joint is mainly used for space welding components and is a fusion welding joint with ideal stress. It is commonly used in specific environments such as high-pressure boiler accessories.

3. Lap joint: This type of joint is easy to prepare, but reduces strength. It is mainly used for connecting stainless steel water pipes, and also for connecting small pipe diameters.

4. Corner joint: Corner joints only serve as connections and are commonly used for the connection of some corner welds, but are not suitable for pipeline systems with crevice corrosion sensitive media and high cleanliness requirements.

Overall, different types of welded fittings are suitable for different scenarios and requirements. When selecting welded pipe fittings, not only should the usage requirements, welding difficulty, and construction conditions be considered, but also their performance and safety reliability.
