Description

Elbow

Steel pipe elbow is a key parts in a piping system for to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction.

According to fluid direction of the pipelines, elbow can be divided into different degrees, such as 45 degree, 90 degree,180 degree, which are most common degrees. Also there has 60 degree and 120 degree, for some special pipelines.

Elbows are split into two groups, if the radius is the same as pipe diameter (Center-to-Face dimension of 1.0 X diameter ), it called Short Radius Elbow (SR elbow) used normally for low pressure and low speed pipelines or in tight areas where clearance is the main issue. If the radius is larger than pipe diameter (Center-to-Face dimension of 1.5 X diameter) then we call it a Long Radius Elbow (LR Elbow) used for high pressure and high flow rate pipelines.

As per the connection with pipe, elbows could be classified as Butt Welded Elbow, Socket Welded Elbow and Threaded Elbow. According to the valve body material, it has stainless steel, carbon steel and alloy steel elbow.

Reducer

Steel pipe reducer is a component used in the pipelines to reduce its size from large to small bore in accordance to the inner diameter.

Reducer Types

There are two types of reducer, concentric reducer and eccentric reducer.

Concentric Reducer                                                       Eccentric Reducer

Pipe Reducer Material Types

The reducers can be made of Carbon Steel, Alloy, or Stainless steel and much more.

For Carbon Steel Reducer:

A234 WPB, A420 WPL6, MSS-SP-75 WPHY 42, 46, 52, 56, 60, 65 and 70.

For Stainless Steel Reducer:

ASTM A403 WP 304, 304L, A403, 316, 316L, 317, 317L, 321, 310 and 904L, etc.

For Alloy Pipe Reducer:

A234 WP1, WP5, WP9, WP11, WP22, WP91 etc.

Tee

Types of steel pipe tee

According to branch diameters and functions there are: Equal Tee and Reducing Tee (Reducer Tee)

According to connection types are: Butt Weld Tee, Socket Weld Tee and Threaded Tee

                               Butt Weld Tee                                                          Socket Weld Tee                                                     Threaded Tee

According to material types there are: Carbon Steel Pipe Tee, Alloy Steel Tee and Stainless Steel Tee

Applications of Steel Pipe Tee

• Oil and gas transmissions
• Petroleum and Oil refining
• Water treatment systems
• Chemical Industries
• Sanitary tubing
• Power stations
• Machines and equipment
• Heat Exchanger

Cap

Steel Pipe Cap is also called Steel Plug, it usually welded to the pipe end or mounted on the external thread of the pipe end to cover the pipe fittings. The convex cap have several shapes: a hemispherical cap, an elliptical cap, a dish cap, and a spherical cap.

We also use caps to cut off the transition and the connection treat can be butt weld, socket weld and thread connection according to use requirements.

End Caps are used for connecting pipes of different diameters and find wide applications in various chemicals, construction industries, paper, cement & ship builders.

Types for steel pipe cap

Ranges from connection types, there are: Butt weld cap, Socket weld cap
Ranges from material types, there are: Carbon steel pipe cap, Stainless steel cap, Alloy steel cap

Bend

Steel pipe bend is a bending pipe that used to change the pipeline direction. It is similar to pipe elbow, but differently pipe bend is longer than elbow and usually manufactured for the specific needs. 3D and 5D bends are most common use in long pipelines, since they provide better efficiency in changing directions. After that is 6D and 8D bend, as the compensation to complete for small degree change.
