Lap Joint Stub End BW fittings

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.

Concentric reducer in a pipe system, its making process and its difference between a eccentric reducer.

Elbows and seamless elbows are often used in the bending parts of pipes to change the direction of pipes Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

1/2 in bend is small diameter fitting in pipe fittings.The degree of bends can be customized by clients.Carbon steel pipe fitting can be used to satisfy many applications because of the great functions and affordable price.

BW elbows have the most wide used range in all types of elbows.Shanghai Zhucheng is an excellent supplier for pipe fittings,all the fittings made from carbon steel and alloy steel will have anti-rust paint,and stainless steel fittings will have anti-rust oil to protect the fittings in the sea transportation.

It helps to change direction at 90 degree, and is commonly used to connect hoses to pumps, deck drains and valve.SR 90 degree elbow is the same as the pipe elbow mentioned above, but the diameter is shorter. Therefore, this kind of steel elbow is often used when space is not enough.A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. Available in many materials like silicon, rubber compounds, galvanized steel etc.

S31803 90 degree elbow is a kind of stainless steel with two-phase structure of ferrite and austenite. It combines the high strength of ferritic stainless steel with the good toughness and corrosion resistance of austenitic stainless steel.

Carbon steel pipe fittings are used in many applications because of its great excellent functions.Carbon steel pipe fittings can manufactured as THD (threaded) fittings,SW (socket weld) fittings and (BW) butt welded fittings.The specifications are in the content below.

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.

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.

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.

Butt welded lateral tee is a special type of BW tees.It is different from the normal tees as the lateral tee can change the direction of the pipe system in 45 degree.Carbon steel fittings are the most used fittings as carbon steel material has great functions and affordable price.

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.

Steel tee is a T-shaped pipe fitting with three branch pipes. It is used to divide pipes to adjust flow and change direction.

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.

A403 WP304  eccentric reducer is a pipe fitting used to connect pipes of different diameters, and the central axes do not overlap, which means there is an eccentricity. The eccentric reducer has two ends, one with a larger diameter and the other with a smaller diameter.

BW cap is used to close the pipe system,the function is similar to plug.A234 WPB is a commonly used grade for carbon steel in American Standard.SCH 40S is represents a wall thickness of butt welded fittings.The commonly used wall thicknesses for BW fittings are SCH 40,SCH 80.

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 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.

‘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 connection methods of elbow and pipe include: direct welding (the most common method), flange connection, hot melt connection, electric fusion connection, thread connection and socket connection

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.

If the radius is the same as pipe diameter (Center-to-Face dimension of 1.0 X diameter ), it called Short Radius Elbow (SR elbow) used normally for low pressure and low speed pipelines or in tight areas where clearance is the main issue. If the radius is larger than pipe diameter (Center-to-Face dimension of 1.5 X diameter) then we call it a Long Radius Elbow (LR Elbow) used for high pressure and high flow rate pipelines.

Steel pipe bend is a butt welded fitting to transport fluids or gas.The degree of steel bend will be customize according to the client’s demend.Pipe bend and elbow have some similarity,you could find the summary “pipe bend VS elbow” below.

LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing, It helps to change direction at 90 degree.

Alloy steel butt-weld pipe caps are mainly used to close pipeline systems to ensure that the fluid in the pipeline will not leak.It is usually welded at the end of the pipeline to provide a reliable sealing effect.
