A420 WPL6 Concentric Reducer

What is the use of Weldolet?

What is a Concentric Reducer,what about its specification and advantages.

Concentric reducers will change kindly between the pump and piping， Concentric reducers are used to connect pipe segments or pipe segments on the same axis.

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

he pipes cannot appreciate because of what the external arrangement of the pipe reducer seems but the flow of the pipe is changed by the internal width conical transition arrangement.

BW (butt welded) reducer can be concentric (COC) reducer and eccentric (EEC) reducer.Among these two types,concentric reducer is more commonly used.The materical of reducer can be carbon steel,alloy steel and stainless steel.Clients can choose different material as their demands.

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.

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.

Concentric Reducer (COC Reducer),is one type of BW reducer.The other type is Eccentric Reducer (ECC Reducer).The two types reducers can meet different demands,You could find the “Concentric VS Eccentric” below to learn the usages for these two types reducers.

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.

Compared to 90 degree elbow, 45 degree elbow produces less friction, and with the lower pressure. 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.

A234 WPB/WPC BW concentric reducers are carbon steel butt welded fittings,among these,A234 WPB is more chosen in many industries.BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.

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.

DN1400 BW elbow is a very large size in pipe fittings.The size of fittings are important for piping systems.Carbon steel fittings are used in many applications because of its great excellent functions.

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.

SR (short radius) elbow is only for 90 deg elbow.SCH XXS is the biggest wall thickness in butt welded fittings.The commonly used wall thicknesses:SCH 40 , SCH 80.The wall thickness more bigger,the bearded pressure of the fittings can be higher.

The pipes cannot appreciate because of what the external arrangement of the pipe reducer seems but the flow of the pipe is changed by the internal width conical transition arrangement. 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.

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.

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.

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.

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.

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.

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 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.

The function of a 45 Degree Long Radius Elbow is same as 90 degrees long and short elbow, but the measurement and dimensions are different to that of a 90 degree long and the short elbow.

‘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.
