ASME B16.9 Pipe Fitting Insulation Elbow Size Chart

According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).

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.

The stub end is usually a short section of pipe fittings, with one end being a flap structure, and the other end can be a stub end or special processing according to specific needs. The turning part is designed to facilitate the connection with other pipe fittings or equipment.

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.

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

Stainless steel BW tees are always used in many corrosive environments because of the corrosion resistance of stainless steel.ASTM A182 F316 is a commonly used 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.

ASTM A234 WPB pipe fittings are have a large size:1/2″-80″.32 in carbon steel butt welded elbow is a common used size in large size of BW elbows.

Concentric reducers are easy to transport mud and grinding fluid and are suitable for corrosive operations , It will change kindly between the pump and piping.

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.

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.

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.

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.

Steel pipe tee has three branches that can change fluid direction. It has T-shaped or Y-shaped, and include Equal Tee and Reducing Tee (Reducer Tee). Steel tee is widely used in pipe networks for convey liquids and gases.

Equal diameter tee, also known as straight tee, the branch diameter of the tee is the same as the pipe diameter of the tee. The three branches of tee have same diameters.

Butt welded 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 BW fittings specifications in the content below.

Pipe elbows have three types:THD (threaded),SW (socket weld),BW (butt welded).These elbows used different connections to connect with the pipes in piping system.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel fittings can used over 50 years.

304/316L BW tees are the most used tees in stainless steel tees.304/316L are the most used grades in American Standard.Tees can be Equal Tees and Reducing Tees.You could find the summary “Equal VS Reducing Tee” in the content below.Stainless steel pipe fittings are populat because of the excellent functions of corrosion resistance.

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.

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.

Schedule 80 elbow is BW pipe fittings,schedule is also called “SCH”,it is represents the wall thickness of butt welded fittings and steel pipes.The commonly used wall thicknesses: SCH 40,SCH 80.

A234 WPB BW reducer has the most wide ragnge of applications in all types of butt welded reducer, because A234 WPB is the most used grade in carbon steel.Carbon steel pipe fittings are accepted in many projects because these fittings have great functions and reasonable price.

A equal tee’s usage,dimension and features.

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.

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.

90 deg 4D bend is belongs to butt welded fittings.4D means the radius of the bend is 4 times long the dimension of the pipe bend.API A53B is a great of carbon steel materical for pipes and bends in American Standard.

Pipe tees can be equal tee and reducing tee.These tees have same functions,the only difference is the reducing tee can reduce the flow in the piping system.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

ASME B16.9 cross is a pipe fitting used to connect four pipes together, and the connection is achieved by welding. It plays a role in diversion or confluence in the pipeline system and is an important connector in the pipeline layout.
