Rducing Tee Schedule 40

Carbon steel butt welding 90 degree elbow is a connector specially designed for use in piping systems. Its main function is to create a 90 degree turn in the pipe so that the fluid can flow along a predetermined path.

usage,specification of a equal tee and ite difference between a reducing tee.

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.

Concentric reducers are beneficial to use where different ratings and to wear protection is required in conveying between flanges or pipes. nd the pipe is connected through conical transition section on the same axis.

The elbow radius mean curvature radius. If the radius is the same as pipe diameter, it called short radius elbow, also called SR elbow, normally for low pressure and low speed pipelines. If the radius is larger than pipe diameter, R ≥ 1.5 Diameter, then we call it a long radius elbow (LR Elbow), applied for high pressure and high flow rate pipelines.

Steel pipe elbow is a key part in a pressure piping system used to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe and thus the fluid direction turn to a certain direction of 45 degree or 90 degree. This change in fluid flow direction adds pressure losses to the system due to impact, friction and re-acceleration.

Concentric reducers provide an in-line conical transition between pressurized pipes of different diameters. It is cone-shaped, and is used when there is a shift in diameter between pipes. 

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.

Butt weld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to directly weld the elbow and steel pipe. Butt welded elbows have beveled ends to allow for ease of welding. This bevel allows for full penetration weld in most of the cases. Butt welded elbows are mainly used for elbow with higher pressure and temperature.

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.

Compared to 90 degree elbow, 45 degree elbow produces less friction, and with the lower pressure. 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.

The characteristic of concentric reducers is that their center lines coincide, that is, the centers of the large and small heads are on the same straight line. This design allows the flow direction of the fluid to remain basically unchanged when passing through the reducer, reducing the resistance caused by the change in flow direction.

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

ASME B 16.9 tee is BW (butt welded) tee belong to butt welded fittings.These tees can bu equal type or reducing type.Normal tees can change the direction of the pipe system of 90 deg.And tees also have lateral tees to change the direction of 45 deg.

Carbon steel pipes have a wide using range because it has great functions and affordable price.It can be welded pipe and seamless pipe,among these,the more used type is welded pipe.Welded pipes also have different types:LSAW pipe,SSAW pipe and ERW pipe.

45 deg BW elbow can change the direction of fluids or gas by 45 deg,it only has LR (long radius) type while 90 deg butt welded elbow has both LR and SR(short radius) types.Carbon steel is the most used material in pipe fittings because it has great functions to satisfy many applications.

BW elbows have the most wide used range in all types of elbows.Shanghai Zhucheng is an excellent supplier for pipe fittings,all the fittings made from carbon steel and alloy steel will have anti-rust paint,and stainless steel fittings will have anti-rust oil to protect the fittings in the sea transportation.

The radius of both the 45 degree and 90 Degree long and short elbow is the same however, the center to face dimension is not equivalent due to the smaller degree of bend.

BW ELBOW are installed between different lengths pipe or tubing. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

A234 WP11 elbow is a pipe fitting used to change the direction of the pipeline. It is made of alloy steel. Its basic structure is a curved tubular part, usually with connection interfaces at both ends to connect with other pipeline components.

Concentric reducer’s dimnesions and its usage and advantage

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.

10in equal elbow is used to transport flow in piping system.A234 WPB is the most used grade for carbon steel butt welded fittings.Elbows can be 90 degree and 45 degree.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.

The function of an end cap is to block off the end of a line a piping system, This is achieved by placing the end cap over the open line and welding around the point.

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.

According to its radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow means that its radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, r = 1.5D. Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, r = 1.0d.

Classify,specification of a BW 90 degree elbow

BW 90 degree elbow is the most used elbow in all types of elbows.BW fittings are popular because it can achieve strong and permanent connection.Stainless pipe fittings are famous for the excellent anti-corrosive function.Shanghai Zhucheng can supply many kinds of pipe fittings made from stainless steel.
