Elbow manufacturers model complete book

In modern industry, the design and manufacture of pipeline system is undoubtedly a crucial part. As an important part of pipeline connection, the quality and type of elbow directly affect the operation effect of the whole pipeline system. The elbow is used to change the direction of the pipe, and can also be used to connect pipes of different diameters to adjust the flow direction and flow rate of the fluid. Therefore, understanding the type and manufacturer of the elbow can help engineers and designers choose the right product, but also improve the stability and economy of the system.

### 1. Basic concept of elbow

Elbow is a pipe connection piece, mainly used to change the direction of the pipe. Common elbow angles are 30 degrees, 45 degrees, 60 degrees and 90 degrees, etc. The specific choice is based on the design requirements of the pipeline. Elbows are made of a variety of materials, including but not limited to carbon steel, stainless steel, alloy steel, plastic, fiberglass, etc. Each material elbow has its own properties and application areas.

2. Classification of elbows

Elbows can be classified according to different criteria:
