Elbow - A Type of Pipe Fitting Used to Change the Direction of the Pipeline
This pipe fitting can be divided into three commonly used models based on angles: 45 °, 90 °, and 180 °. It also includes non-standard angles such as 60 ° that meet special engineering requirements
Flange also Called Flange Connection or Flange Joint.
Flanges are mainly used for connecting pipes, containers, valves, pumps, or other equipment
TEE Way Fittings, Also Known As Pipe Fittings, Three-Way Joints, Etc
Mainly used to change the direction of fluid, it is generally made of materials such as carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon inert gas, PVC, etc

Matching principle between elbow pressure rating and pipeline system design pressure
Nov 08, 2025
The pressure rating of the elbow (such as Class 150/300/600) needs to be strictly matched with the design pressure, temperature, and medium characteristics of the pipeline system to ensure safe operation of the system. The following are the specific matching logic and key points:
