Common types of national standard pipe fittings

Under national standards, common national standard pipe fittings include elbows, flanges, blind flanges, reducers, tees, tees, socket fittings, heads, reducers, etc. These accessories play important roles in the pipeline system, such as connection, control, direction change, and diversion. They are produced strictly in accordance with national standards, ensuring product quality and interchangeability.

1. Elbows: fittings used to change the direction of pipelines, which can be divided into 90 degree elbows, 45 degree elbows, etc. according to the bending angle. The national standard elbow has precise bending radius and angle, which can ensure smooth flow of fluid in the pipeline.

2. Flange: A component used to connect two pipes or equipment, tightly connected together by bolts or other fasteners. National standard flanges have standardized dimensions and connection methods, making them easy to install and maintain.

3. Three way and four way fittings: fittings with three and four branches respectively, used to achieve pipeline diversion or merging. The national standard three-way and four-way have precise branch angles and connection sizes, which can ensure uniform distribution and flow stability of fluids.
