Carbon Steel Pipe Fittings

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.

LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing. It helps to change direction at 90 degree, and is commonly used to connect hoses to pumps, deck drains and valve.

LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing. 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.

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.

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.

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.

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

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.

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D.
Short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, i.e R = 1.0D

An equal tee, otherwise called straight tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefore, used to connect two pipes of the same nominal diameter.

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 pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.

Steel pipe bend is belong to butt welded fittings.The bend radius R should greater than or equal to 3 times of the outside diameter.Bends could manufacture as the customize degree to meet the client’s demends.

Branches of tees have two types:Equal tee and Reducing tee.These two types tees have same functions,but reducing tee has one more function:it can reduce the flow of the gas or fluids.Butt welded fittings are the most used fittings in many applications because the size range of the BW fittings is big.

BW elbow types have BW (butt welded),SW (socket weld),THD (threaded).The butt welded elbow is the most used type.Elbows have two shapes:Equal and Reducing.Shanghai Zhucheng is a pipe fittings manufacturer who can supply 45 deg,90 deg and 180 deg elbows.

Carbon steel elbows are the most commonly used elbows in all the types and material elbows.Large dimensions elbow is butt welded fitting,you can find the butt welded fittings specification below.

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.

There are various types of ASME B16.11 socket-welding fittings, such as Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, Union and Sockolet; while ASME B16.11 threaded fittings can be furnished in product forms of Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, plug and bushing.

Large diameter flat welding flange has less high-pressure suitability compared to its weld neck counterpart. The basic ring style is suitable for the occasion of low pressure. The butt weld category of the flange is known as a weld neck flange. It suits the occasion of high temperature and pressure as defined in the ASME B16.47 code.

The length of the threaded nipple is usually determined by the total length of the thread. Swaging nipple (also known as reducing nipple) is a forged pipe fitting. It is used to change the diameter of the pipe and connect two pipes of different sizes.

There are two types of 90 deg elbows:LR (long radius),SR (short radius).45 deg eblows are also have wide applications,be attention,45 deg elbow only have LR type.Butt welded pipe fittings have the most large used range as it can be 1/2″ – 80″.

Carbon BW tee is wide used in many applications because welded connection can provide permanent connection.Schedule XS is wall thickness of this tee in the picture.In addition,the commonly used wall thicknesses:SCH40, SCH80.

Carbon steel tee is a commonly used tpye of tees.This is butt welded (BW) carbon steel tee in the picture.it can welded with pipes to achieve permanent connection.Equal tee only can change the direction of the pipes while reducing tee can also reduce the flow of the fluids or gas.

According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).

The main purpose of using pipe caps is to waterproof the connections. They are also used to close the the ends of hydraulic or pneumatic pipes and tubes. The use of Forged End Pipe Caps is common in many industries such as oil and gas industries, chemical industries and water supply lines.

An equal tee, otherwise called straight tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefore, used to connect two pipes of the same nominal diameter.
