90 Degree Bend

What is a CAP nipple and what about its specification and advantages.

‘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.

BW (butt welded) reducer have two types:Eccentric Reducer and Cocentric Reducer.Reducer only has welded connection.However,swage nipple which belong to forged fittings has same function to reducer.

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.

Welded steel pipes are popular because of the strong and permanent connection,the ends of the pipes can welded with flanges.Slip on (SO) flange can slip on the pipe,and then welded on the pipes.

90 deg stainless steel elbow is a popular type of elbows.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.Shanghai Zhucheng is an excellent pipe fittings manufacturer who supplys high quality pipe fittings and flanges for years.

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.

Concentric reducer’s dimnesions and its usage and advantage

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.

90 deg elbow is the most chosen degree in elbows.There are also 45 deg and 180 deg elbows.Elbows can be Equal Elbow and Reducing Elbow to satisfy different demands.ASTM A234 WPB is a material grade in American Standard repersents carbon steel butt welded fittings.

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.

BW reducer and elbow both commonly used pipe fittings used welding type to connect with pipes and transport flow in piping system.ASME B16.9 fittings are butt welded fittings according to 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.

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

Lateral tee is a special type of BW tees,it can branch the fluids or gas in 45 deg.Galvanized steel pipe fittings has better anti-corrosive function than normal carbon steel fittings.Galvanized Steel Pipe Fittings have similar corrosion resistance as stainless steel fittings,but more cheaper than stainless steel pipe fittings.

SS 304/316 pipe tees are popular because these tees have excellent corrosion resistance.Tees can made for three types:BW (butt welded) tee,SW (socket weld) tee,THD (threaded) tee.Clients can choose different type of tees to satisfy different demands.ASME B 16.9 is represents butt welded fittings in American Standard.SW fittings and THD fittings are belong to forged fittings which marked as ASME B 16.11.

BW 3D elbow is belong to Butt welded (BW) elbows.3D means the radius is 3 times of dimensions long.A234 WPB is the most used grade of carbon steel butt welded (BW) fittings according to American Standrad.The degree of the butt welded 3D elbow can be 45 deg, 90 deg and 180 deg.

ASME B16.9 tee is an American Standard butt welded fitting.BW tees can be two types:Equal Tees and Redcing Tees.These tees have similar functions but reducing tees can reduce the flow while equal tees can not.You could find the summary “Equal VS Reducing” in the content below.

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

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.

Concentric reducer is used to join pipe sections or tube sections on the same axis. It is cone-shaped, and is used when there is a shift in diameter between pipes. 

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

Concentric reducer’s dimnesions and its usage and advantage

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.

2”90°stainless steel elbow is a commonly used pipe fitting in the pipeline system. It is mainly used to change the direction of the pipeline, make the pipeline turn 90°, and connect two pipes with the same or different nominal diameters.

Tee welding joints are formed when two pieces intersect at a 90° angle. This results in the edges coming together in the center of a plate or component in a ‘T’ shape. Tee joints are considered to be a type of fillet weld, and they can also be formed when a tube or pipe is welded onto a base plate.
