ASME B16.9 Steel Pipe Fittings Long Radius 90DEG Elbow

he pipes cannot appreciate because of what the external arrangement of the pipe reducer seems but the flow of the pipe is changed by the internal width conical transition arrangement.

The pipes cannot appreciate because of what the external arrangement of the pipe reducer seems but the flow of the pipe is changed by the internal width conical transition arrangement. It can be axially shifted and externally reconfigured to offer more efficient reducer connection. 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.

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.

BW carbon tee are popular because carbon steel has great functions and cheap price.Coated pipe fittings also used in piping systems as the coating can enhance the functions for normal carbon steel.Galvanized coating is the most used coating,it can enhance the anti-resistance function.

A182 F316 reducer is a stainless steel butt welded fitting which can used in some corrosive environments because of the high corrosion resistance of stainless steel.BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.There are many differences between the two types of reducers,you could find the summary “Concentric VS Eccentric” in the content below.

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 are mainly used for elbow with higher pressure and temperature than other connection types. According to the valve body material, it has stainless steel, carbon steel and alloy steel 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.

Steel pipe tee is a pipe fitting used to tansport the flow in the piping system.Carbon steel fittings are used in many applications becasue of its great excellent functions.

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.

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

Butt weld elbow is the most used type of elbows.It can welded with the pipes to achieve strong and permanent connection.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel fittings can used over 50 years.

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.

ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on.
In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.

Concentric reducers will change kindly between the pump and piping， Concentric reducers are used to connect pipe segments or pipe segments on the same axis.

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

Elbows are split into two groups which define the distance over which the flowing fluid change direction; the center line of one end to the opposite face. This is known as the “Center to Face” distance and is equivalent to the radius through which the elbow is bent.

BW elbows are belong to butt welded fittings,wall thickness of BW fittings decided the pressure that the fittings can resistance.Wall thickness SCH 40 is a commonly used wall thickness in butt welded fittings.

The body of the branch abutment is made of high-quality forgings, which are made of the same materials as the pipes, including carbon steel, alloy steel, stainless steel, etc. The branch pipe seat and the main pipe are welded

90 degree steel pipe elbow functioned to change fluid direction by 90 degree, so also named as vertical elbow. It is the common degree in all the pipeline systems and used most in all different degree of elbows

ASTM A234 WPB Eccentric Reducers are pipe fittings used to connect two pipes of different diameters, with the centerline of one pipe being offset from the other.

The Butt Weld 45 Degree Elbow is a pipe connector in the shape of a curved pipe section with a bending angle of 45°. It consists of a curved part and straight edge parts at both ends. The radius of curvature of the curved part is an important parameter, which is usually determined according to the nominal diameter of the pipe and the use requirements.

Butt Weld Fittings include elbows, tees, cross, caps and reduces. These fittings are the most common type of welded pipe fitting and are specified by nominal pipe size and pipe schedule. Buttweld fittings are manufacture by seamless or welded pipe and are formed to get the shape of elbows, tees and cross etc.

There are two types of tees:Equal Tee and Reducing Tee.Both types of tees can branches the pipes but reducing tees can also reduce the flow.Schedule 40 is a commonly used wall thickness in butt welded fittings.

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.

Radius of Long Radius (LR) Elbows is 1.5 times the pipe diameter. Radius of Carbon Steel Short Radius Elbow is 1.0 times the pipe diameter. Carbon Steel Seamless Elbow are in demand for use between two lengths of pipe or tube allowing a change of direction, usually these elbows distinguished by connection ends.

45 deg elbow has three types:BW (butt welded) elbow,SW (socket welded) elbow and THD (threaded) elbow.Elbows can also be 90 degree and 180 degree to meet different demands.Shanghai Zhucheng is an experienced pipe fittings manufacturer who supplys high quality pipe fittings and flanges for many years.

90° Steel Pipe Elbow is the most commonly used elbow type in pipe system with the function to change the direction of fluid in 90 degree. It connects pipes with same or different diameter.

ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on.
In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.
