What is a Carbon Steel Elbow?
Carbon steel elbow is a connection component used in piping systems, mainly used to change the direction of the pipeline or connect different pipeline sections. It is made of carbon steel.
Common Carbon Steel Elbow Classifications
Carbon steel elbows can be divided into many types according to different classification standards.
The common types are mainly the following two:
45° Carbon Steel Elbow
The 45° carbon steel elbow is a common pipe connector, primarily used to change the direction of fluid in a piping system, specifically at a 45-degree angle.
Compared to other elbows, the 45° elbow provides a smoother turn, reducing fluid flow resistance and making it suitable for use in a variety of industrial piping systems.
90° Carbon Steel Elbow
90° carbon steel elbow is a pipe fitting used in piping systems to change the direction of the pipe, making the pipe turn 90° .
It is widely used in water supply and drainage, HVAC, gas, industrial pipelines and other fields.
Elbow Applications
- Chemical pipeline diversion;
- Building drainage systems;
- Heating, ventilation, and air conditioning (HVAC) installation;
- Oil and gas transportation;
- Food processing equipment;
- Marine piping layout;
- Agricultural irrigation systems;
- Fire protection piping configuration;
- Laboratory gas piping;
- Home renovation and decoration
Elbow Standards
The internationally recognized elbow standards are the US national standards ANSI B16.9 and B16.28. These standards cover an outside diameter range of 1/2″ to 80″.
Generally, elbows up to 24″ are made from seamless steel pipe, while those from 26″ to 80″ are stamped from steel plate and then welded.
Wall thicknesses range from a maximum of 60mm to a minimum of 1.24mm.
