ASTM A234 CONCENTRIC REDUCER BW B 16.9

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.

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.

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.

These Stainless Steel Pipe Fittings are best known for their heat resistance, creep strength and tensile strength. Machined and fabricated to meet your diverse piping requirements, these pipes fittings exhibit excellent corrosion resistance in a wide range of atmospheric environments.

The function of an end cap is to block off the end of a line a piping system, This is achieved by placing the end cap over the open line and welding around the point.

90 deg LR (long radius) elbow is the most used type of BW elbows.Butt welded elbows also have SR (short radius) elbows.Shanghai Zhucheng has experienced pipe fittings factory that can supply high quality goods for many years.

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.

Steel pipe elbows have seamless and welded version, normally in 90 degree, 45 degree & 180 degree. Material are carbon steel, alloy steel & stainless steel. BW 90 degree elbow is formed by hot forming and connects steel pipes or other pipe fittings through butt welding process

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

Stainless 90 deg elbow has better anti-corrosive function than other material elbows.90 degree elbow can be two types: LR (long radius) and SR (short radius).Elbows can also be 45 degree,but 45 deg elbow only has LR type.

‘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.

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.

Steel pipe bend two pipes into a certain angle and connects them together to change the direction of the pipe. it could be bend directly from a finished pipe with cold bending processes, to different degrees.

A concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1″ pipe transitions into a 3/4″ pipe and the top or bottom of the pipe doesn’t need to remain level.

BW Elbow Fittings can also attach to rubber with stainless steel clamps. Available in many materials like silicon, rubber compounds, galvanized steel etc,

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.

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.

SSAW steel pipe in the production process, we need to pay attention to a series of matters. Except for the following test items, according to the API standard and other relevant standards and the special requirements of some users, but also the need for steel, steel pipe and other tests Destructive tests, including physical and chemical properties of the raw materials into the plant sampling, visual inspection of 100% steel .

Spiral wound gasket (SWG) is a fitting used with flanges.ASME B16.20 is the American Standard for gasket.

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.

Pipe Elbow is installed between two long pipes for changing the direction of the flow of liquid or fluid. These are commonly available in two types; 90 degrees and 45 degrees. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

Carbon steel butt welded 90° elbows are belong to ASTM A234 WPB pipe fittingsBW 90 deg elbows could be made in two types:LR (Long Radius) and SR (Short Radius).The angle of pipe elbows are 45deg and 90 deg.Only 90 deg elbows have LR.

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.

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.

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.

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.

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.
