Buttwelding Fittings

DN950 long radius elbow is one type of large dimension elbows,there is also short radius elbow to choose.ASME B16.9 elbow is butt welded elbow according to American Standard.

DN900 LR elbow is large dimension fitting,for the large dimension,the elbows always be butt welded.Wall thickness STD is a commonly used thickness of BW fittings,the other commonly used wall thickness are SCH 40, SCH 80.

ASME B16.9 butt welded fittings are American Standard BW fittings.COC Reducer means concentric reducer,BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.

3/4in BW tee is a normally used fitting in butt welded fittings.A403 WP321 is a grade for stainless steel.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

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.

45 degree elbow is second common use after 90 degree elbow. 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.

A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. Elbow connectors can link pipes to avoid water leakage and air leakage between pipes.

Carbon steel elbows are curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications.

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D. Most elbows are available in short radius or long radius variants. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

‘The long radius elbow is the elbow which the radius of curvature of is 1.5 times the diameter of the pipe; if the radius of curvature is greater than 1.5 times, the long radius elbow will be called the bend. The short radius elbow means that the radius of curvature of the elbow equals the diameter of the pipe, or 1 time the diameter of the pipe in common words.

The long radius is used most commonly, and it is also the default radius. When it is the place with the high pressure or the high flow rate, the long radius elbow is usually used. If the resistance requirements of the solid transmission pipeline are strict, the larger radius elbows will be used.

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.

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.

Long Radius (LR) Elbow is also called LR elbow – means the radius is 1.5 times the pipe diameter
L/R 45°Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.
L/R 90°Elbow: Long radius 90 degree elbow changes the direction by 90 degrees.
L/R 180°Elbow: Long Radius 180 degree return bend allows complete reversal of flow.

Steel pipe elbow is an important parts in plumbing pipeline systems and used to change the fluid directions. It ranges in different types as per body material there are stainless steel elbow, carbon steel elbow, and alloy steel;

12 IN Carbon Steel Elbow is an important pipe fitting in piping system as it can change the direction of the pipes in 90 degree.ASTM A234 WPB is a commonly used grade for carbon steel in American Standard.

Large Size 90 Degree Elbow have an improtant use in piping system to transport flow.Carbon steel elbow is the most used material because of the great functions and affordable price.

Large Diameter Concentric Reducer is belong to butt welded fittings because BW fittings size range is 1/2″-80″ while the forged fittings only have 1/8″-4″.ASTM A234 WPB is represents to carbon steel pipe fittings in American Standard.

Large diameter equal tee is belong to butt welded fittings because BW fittings size range is 1/2″-80″ while the forged fittings only have 1/8″-4″.Carbon steel fittings are used in many applications because of its great excellent functions.

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.

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.

24in equal tee is belong to large dimension fittings.SCH 40 is a commonly used wall thickness for butt welded fittings.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.

45in BW reducer is belong to large dimension butt welded fittings,STD is a commonly used wall thickness for BW fittings.Other commonly used wall thicknesses for BW fittings are SCH 40,SCH 80.

BW elbow and reducer are both commonly used pipe fittings in piping systems.A234 WPB is the most used grade for carbon steel butt welded fittings.

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.

A234 WPB/WPC BW 90 degree elbows are carbon steel butt welded fittings.Elbows also have 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.

ASTM A234 WPB is a common grade for 90 degree long radius elbow, which is one of the highly demanded. They available in a large size and thickness range. They have a good performance and suffices most industrial pipeline needs.

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.

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.

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.
