Carbon steel elbow

Carbon steel elbows are curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications.

Carbon steel elbow

Carbon steel is also known as the iron-carbon alloy containing less than 2% carbon WC. 

With an extensive carbon steel inventory, Sunny Steel carries a wide range of carbon steel elbow in a variety of sizes and pressure ratings to meet your project’s needs—including hard-to-find configurations and sizes.

We supply carbon steel elbows of different standards(ASTM, ASME, NACE, MSS).

Generally also contain small amounts of silicon, manganese, sulfur, phosphorus and carbon steel, in addition to carbon use can be divided into carbon steel and carbon structural steel, carbon tool steel, and ease of cutting structural steel three categories. Carbon structural steel is divided into building structural steel and machinery manufacturing structural steel two kinds.

According to the carbon steel, carbon content can be divided into low-carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25% - 0.6%) phosphorus, sulfur content and high-carbon steel (WC> 6%) can be divided into ordinary carbon steel (containing phosphorus, sulfur higher), high-quality carbon steel (containing phosphorus, low sulfur) and high quality steel (phosphorus, sulfur less), generally, the higher carbon content, the higher the hardness, higher strength but lower ductility.



An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.

Most elbows are available in short radius or long radius variants. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

Elbows are categorized based on various design features as below:

Abrasion resistant elobw

SHS-self-propagating ceramic composite steel pipe and fittings, the new generation of wearable and corrosion resistant engineering pipeline, belongs to "863" Hi-tech Plan products.

It is the ideal wearable and corrosion resistant engineering pipeline, with wear resistance 15 times higher than common steel pipe, smooth inner surface, and favorable liquor resistance.

Pipe elbows

Butt Weld Pipe Fitting Bevel

  • All welded pipe fittings have bevelled end to allow for ease of welding.
  • This bevel allows for full penetration weld in most cases.
  • There are two types of bevels;
    Plain Bevel and Compound Bevel: according to the bevel of welding pipe fittings construction .
  • ASME B16.28, Buttwelding Short Radius Elbows and Returns
Industrial Processes: Bending, squeezing, pressing, forging, machining and more ANSI/ASME B16.25, Buttwelding Ends
ANSI/ASME B16.25 Standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding.

Application of pipe elbows:

Petroleum, chemical, power, gas, metallurgy, shipbuilding, construction, etc.

ELL & ELLS

  • A wing of a building at right angles to the main structure.
  • A right-angled bend in a pipe or conduit; an elbow.
Pipe elbows by radius and degree
Short radius

SR Elbows have a Center-to-Face dimension of 1.0 X diameter usually includes three angles degree ( 45°,90°,180°).

Butt weld 5D pipe bend
Long radius

The radius of LR elbow curvature of is 1.5 times the diameter of the pipe, usally includes three degrees (45° ,90°,180°)

Reducing elbow

The reducing elbow eliminates one pipe fitting and reduces the welding by more than one-third.



Fitting specification, Standard and identification

There are different varieties of pipe fittings made of various materials and available in various shapes and sizes.
