ASTM A234 CONCENTRIC REDUCER BW B 16.9

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.

Specificationo and usage of a 90degree BW elbow.

180 deg BW elbow can change the direction of fluids or gas in 1800 degree.Butt welded elbows can also be 90 deg and 45 deg.90 deg elbow and 45 deg elbow are more commonly used than 180 deg elbow.You could find the surmmary ” 45 degree elbow VS 90 degree 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.

Reducing tee is a kind of pipe fitting whose branch size is smaller than the size of pipeline parts. It is used for main pipe string accessories, solvent welding accessories, side outlet and conflicting soluble welding accessories.

Radius of Long Radius (LR) Elbows is 1.5 times the pipe diameter. Radius of Carbon Steel Short Radius Elbow is 1.0 times the pipe diameter. Carbon Steel Seamless Elbow are in demand for use between two lengths of pipe or tube allowing a change of direction, usually these elbows distinguished by connection ends.

Classify of elbows and how to sperate it into SR and LR Elbows

45 deg elbow can change the direction of fluids or gas in 45 degree.There is also has 90 deg elbow to be chosen.45 degree elbow has many diffences with 90 degree elbow.All types of elbows can be Equal Tee and Reducing Tee to satisfy different demands.

45 degree elbows have same functions to 90 degree elbows,the only different is 45 deg elbow changes the direction of pipes in 45 deg while the 90 deg elbow changes the direction in 90 deg.BW pipe fittings are popular as its strong and permanent connection.

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.

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.

45 degree elbow is widely used in chemical industry, food, water supply facilities, electronic industry, chemical pipeline, horticulture, agricultural production, solar equipment pipeline, air conditioning pipeline and other fields.

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.

Steel Reducing Tee: The branch diameter is smaller than the main line diameter. Tee reducer is usually described as NPS diameters in 4”x 4”x 3”, 4”is the main line pipe diameter, and 3”is the reducing branch

Pipe elbows are fitting accessories which are used widely in various industrial sectors in pipe fitting. A pipe elbow is frequently used in pressurized applications and are available in various shapes and sizes for use in different applications. A pipe elbow is a fitting installed between two lengths of pipe or tube allowing a change of direction, usually in the 90° or 45° direction.

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.

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.

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.

Concentric reducer is used to join pipe sections or tube sections on the same axis The length dimension of the reducer is almost equal to the average of the big bore and smaller bore pipe diameters.

The elbow radius mean curvature radius. If the radius is the same as pipe diameter, it called short radius elbow, also called SR elbow, normally for low pressure and low speed pipelines. If the radius is larger than pipe diameter, R ≥ 1.5 Diameter, then we call it a long radius elbow (LR Elbow), applied for high pressure and high flow rate pipelines.

BW carbon steel reducer is the most used type of BW reducers.Butt welded reducer can be concentric (COC) reducer and eccentric (ECC) reducer to meet different demands.SCH 160 fittings are belong to large wall thickness,these fittings can resist high pressure in piping system.

Reducing tee a one of the type of tees,the other type is equal tee.these two types tees have similar functions,but the reducing tees can reduce the flow.Shanghai Zhucheng is an excellent Pipe fittings manufacturer who supplys high quality fittings for many years.

Elbow is a commonly used connecting pipe fitting in plumbing installation, which is used for connecting pipe bends

ASTM A403 Stainless Steel Butt Weld 45 Degree Elbow refers to the material of forged and rolled austenitic stainless fittings for pressure pipes. Common grades are WP304/L, WP316/L. They can be used into many fields as engineering industry, energy conversion plants etc. ASTM A403 WP304, WP316 Elbow are buttweld fittings made for austenitic stainless steel applications with forged material.

What is Galvanizing?

Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing.

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.

SS400 90 DEG elbow is used to transport flow in piping system.Butt welded fittings used welded connection to connect with the pipes to achieve the strong and premanent connection.

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.

It is used to handle any high or low weight fluid flow through the tee.Reducing tee is a kind of pipe fitting whose branch size is smaller than the size of pipeline parts. It is used for main pipe string accessories, solvent welding accessories, side outlet and conflicting soluble welding accessories. Such fittings are important because they meet two needs, that is, to connect or separate liquid streams. They are widely used in positive and vacuum applications.
