90° Butt Weld Elbow

Butt weld fittings are manufacture by seamless or welded pipe. For pipe fittings manufacturers, the forming process of welded pipe and seamless pipe is basically same. Butt welded fittings can be divided into carbon steel butt welded fittings and stainless-steel butt-welded fittings

Stainless reducer is a butt welded pipe fitting used to reduce the flow in the pipe systems.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

The stub end is usually a short section of pipe fittings, with one end being a flap structure, and the other end can be a stub end or special processing according to specific needs. The turning part is designed to facilitate the connection with other pipe fittings or equipment.

180 deg elbow is not commonly used but indispensable pipe fitting.180 degree elbow can changes the pipe systems in 180 degree.Carbon and alloy steel pipe fittings always be chosen in many industries because of the great functions and reasonable price.

Carbon steel reducer is a commonly used BW fitting.Butt welded pipe fittings used welded connection to connect with pipes in piping systems.These BW fittings are popular because of the strong and permanent connection.Carbon steel is the most used material in many applications because of the great functions and affordable price.

Concentric reducer’s dimnesions and its usage and advantage

BW elbow types have BW (butt welded),SW (socket weld),THD (threaded).The butt welded elbow is the most used type.Elbows have two shapes:Equal and Reducing.Shanghai Zhucheng is a pipe fittings manufacturer who can supply 45 deg,90 deg and 180 deg elbows.

Concentric Reducer (COC Reducer),is one type of BW reducer.The other type is Eccentric Reducer (ECC Reducer).The two types reducers can meet different demands,You could find the “Concentric VS Eccentric” below to learn the usages for these two types reducers.

It helps to change direction at 90 degree, and is commonly used to connect hoses to pumps, deck drains and valve.SR 90 degree elbow is the same as the pipe elbow mentioned above, but the diameter is shorter. Therefore, this kind of steel elbow is often used when space is not enough.A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. Available in many materials like silicon, rubber compounds, galvanized steel etc.

Carbon steel tee is the most used type in all tees because carbon steel has great functions and affordable price.Galvanized pipe fittings has better anti-corrosive function than normal carbon steel pipe fittings,galvanized fittings have similar functions as stainless steel fittings,but the price is cheaper than stainless steel fittings.

There are two types of 90 deg elbows:LR (long radius),SR (short radius).45 deg eblows are also have wide applications,be attention,45 deg elbow only have LR type.Butt welded pipe fittings have the most large used range as it can be 1/2″ – 80″.

LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing. It helps to change direction at 90 degree, and is commonly used to connect hoses to pumps, deck drains and valve.

Concentric reducer is used to join pipe sections or tube sections on the same axis. It is cone-shaped, and is used when there is a shift in diameter between pipes. A pipe reducer is available in various specifications, such as a single diameter change and also in a multiple diameter change.

BW (butt welded）reducer has two types:concentric reducer and eccentric reducer.As it is butt welded fitting,its size can be 1/2″ – 80″,so butt welded fittings can be used in many applications.Stainless steel fittings are more expensive but the functions are also better than others.

What is the use of Weldolet?

ASME B16.9 cross is a pipe fitting used to connect four pipes together, and the connection is achieved by welding. It plays a role in diversion or confluence in the pipeline system and is an important connector in the pipeline layout.

0 degree elbow, also called “90 bends or 90 elbows”, are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows.

The lap joint stub end is required when attach the lap-joint flange to the piping system. The stub end and lap-joint flange assembly are used mainly in piping systems that necessitate frequent dismantling for inspection or routine maintenance.

The length dimension of the reducer is almost equal to the average of the big bore and smaller bore pipe diameters. Concentric reducers are easy to transport mud and grinding fluid and are suitable for corrosive operations

ASME B16.9 flanged nipples have a flange structure at one end. This flange is usually for easy connection with other flanges or pipe fittings.

The function of butt weld elbow is to change direction or flow in a piping system. There are the 45°, 90° and 180° .
According to the material, it can be divided into carbon steel, alloy steel and stainless-steel.
According to its radius of curvature, there are long radius  and short radius butt weld elbow.

BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.Stainless pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

Pipe elbows are fitting accessories which are used widely in various industrial sectors in pipe fitting. A pipe elbow is frequently used in pressurized applications and are available in various shapes and sizes for use in different applications. A pipe elbow is a fitting installed between two lengths of pipe or tube allowing a change of direction, usually in the 90° or 45° direction.

BW 90 elbow is the most used degree,there is also 45 deg elbow to choose.These elbows have similar functions,the only difference is the 90 degree elbow can changes the direction in 90 deg while the 45 degree elbow can changes in 45deg.ASME B16.9 is American Standard of butt welded fittings.

BW 180 deg elbow is used to change the direction of pipe system in 180 degree.There are also 90 deg elbow and 45 deg elbow to meet different demands.Carbon and alloy steel are always called “black steel” as the surfer of these steels are black.

The two ends of concentric reducer are designed with large diameter and small diameter, and the pipe is connected through conical transition section on the same axis.

BW Elbow Fittings can also attach to rubber with stainless steel clamps. Available in many materials like silicon, rubber compounds, galvanized steel etc,

ASME B 16.9 lateral tee is one special type of BW tees.It has similar functions to the normal tee,the only difference is the lareral tee can change the direction in 45 degree while the normal one changes in 90 degree.

A234 WPB/WPC BW concentric reducers are carbon steel butt welded fittings,among these,A234 WPB is more chosen in many industries.BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.

24IN carbon steel BW elbows are large dimension fittings,ASME B16.9 is represents butt welded fittings in American Standard.Carbon steel fittings are used in many applications because of its great excellent functions.
