ASME B16.9 45 Degree LR Elbow

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.

45 deg elbow can change the direction of fluids or gas in 45 degree.There is also has 90 deg elbow to be chosen.45 degree elbow has many diffences with 90 degree elbow.All types of elbows can be Equal Tee and Reducing Tee to satisfy different demands.

Concentric BW reducer is one type of butt welded fittings.BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.

90 deg SR (short radius) elbow is a type of BW elbows,90 degree elbow also has LR (long radius) type.Shanghai Zhucheng has expericenced pipe fittings factory which can provide high quality pipe fittings and forged flanges.

What is a CONCENTRIC REDUCER and what about its specification and advantages.

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.

BW elbow can welded with pipes to achieve strong and permanent connection.ASTM A234 WPB pipe fittings are the most popular carbon steel fittings.There is also has A234 WPC for carbon steel fittings.

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.

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.

A pipe reducer is the type of pipe fitting which helps to join two pipes with different diameters. There are various material for The pipe reducers as per the demands of industries and also available in many dimensions.

45 deg elbow can be butt welded elbow and forged elbow.Forged elbows are including SW (socket weld) elbow and THD (threaded) elbow.Stainless steel pipe fittings are popuar because stainless steel has excellent corrosion resistance,stainless steel has using age over 50 years,so the material is more expensive than other materials.

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.

classification,dimension of lateral tee,and its difference from a WYE.

Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbow

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.

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.

Steel pipe bend is belong to butt welded fittings,bends have some similar usages as elbows.However,bends can be customized by clients to satisfy different demands.

Carbon steel elbows are the most commonly used elbows in all the types and material elbows.Large dimensions elbow is butt welded fitting,you can find the butt welded fittings specification below.

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.

These types of tube fittings like male elbows and female elbows have been specifically designed for use on instrumentation, process and control systems and equipment employed in chemical, petroleum, fluid power, electronic and pulp and paper plants.

The function of a 45 degree elbow is the same as a 90 degree elbow, but the measurement of dimensions is different to that of the 90 degree elbow.Compared to 90 degree elbow, 45 degree elbow produces less friction, and with the lower pressure.

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

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.

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.

12in concentric reducer is a normal size pipe fitting that can used for many applications.SCH 80 is a commonly used wall thickness for BW fittings.There are two types of reducer:concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.
