A182 F316 Reducer Concentric VS Eccentric

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

The function of an elbow and What is the difference between LR and SR elbow?

45 degree elbow is widely used in chemical industry, food, water supply facilities, electronic industry, chemical pipeline, horticulture, agricultural production, solar equipment pipeline, air conditioning pipeline and other fields.

45° Pipe Elbow is also known as “45 bends or 45 ells”. The 45° pipe elbow is used to connect tubes at a 45° pipe angle. As the name suggests, this is a pipe fitting device which is bent in such a way to produce 45° change in the direction of flow of the fluid/gas in the pipe.

Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.

BW equal tee is a commonly used tee in many applications.There is also reducing tees to choose.These tees have same functions,the only difference is the reducing tees can reduce the flow in the pipe system.There are the tee specifications in content below.

What is a latera tee and the difference between a wye and a lateral?

oncentric reducers are beneficial to use where different ratings and to wear protection is required in conveying between flanges or pipes.

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 of 45 degree or 90 degree.

The reducing tee has two outlets cut at 90 degrees with the main pipe, and the size of the branch pipe is smaller than the port of the pipeline. It is used for main pipe string accessories, solvent welding accessories, side outlet and conflicting soluble welding accessories

Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.

These concentric reducers are available in the seamless and welded type of construction. 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 reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.There are the applications for eccentric reducer.

A234 WPB elbow is the most chosen carbon steel elbow in all the types of elbows.A234 WPB is carbon steel grade for butt welded fittings;BW elbows have LR (long radius）and SR (short radius).Elbows have 90deg and 48deg to change the direction of the pipe system.

ASTM A182 F304 pipe fittings are inculding many fittings,among these,stainless butt welded elbows are the most common used fittings.For 90 deg elbows,there are two types :LR (Long Radius) and SR (Short Radius).Stainless steel pipe fittings are popular because of the superior functions.

Concentric reducers facilitate the delivery of mud and abrasive fluids and are suitable for corrosive operations and where different ratings and wear protection are required between flanges.

ASME B16.9 BW tee is a butt welded pipe fitting according to American Standard.Carbon steel fittings are used in many applications because of its great excellent functions.Pipe tees can be equal tee and reducing tee.These tees have same functions,the only difference is reducing tee can reduce the flow in piping system.

Pipe crossing is used where four pipes intersect. The cross pipe may have one inlet and three outlets, or three inlets and one outlet. The diameter of the outlet and inlet can be the same or different.

The surface quality and mechanical properties of the elbow are almost the same as the pipe’s. To facilitate welding, the long radius elbow should be made of the same kind material of the pipe to be connected.

Butt welded lateral tee is a special type of BW tees.It is different from the normal tees as the lateral tee can change the direction of the pipe system in 45 degree.Carbon steel fittings are the most used fittings as carbon steel material has great functions and affordable price.

Carbon steel tee is a commonly used tpye of tees.This is butt welded (BW) carbon steel tee in the picture.it can welded with pipes to achieve permanent connection.Equal tee only can change the direction of the pipes while reducing tee can also reduce the flow of the fluids or gas.

Butt welded tee can be equal type and reducing type.Both types can change the direction of the piping system in 90 deg.In addition,the reducing tees can reduce the flow of the fluids or gas.Shanghai Zhucheng is an excellent pipe fittings manufacturer from China who supply high quality fittings for years.

According to the production process, it can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

According to fluid flow direction of the pipes, elbows can be divided into different degrees, such as 45 degree, 90 degree, 180 degree, which are most common elbows. Also there are 60 degree and 120 degree elbows for some special pipelines. This degree is just an representation of the angle by which the fluid flow is going to change after flowing through the said elbow.

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.
