Butt welded elbow is a pipe fitting which used welded connection to connect with the pipes in piping system.BW elbbows have two degrees to choose:90 deg elbow and 45 deg eblbow.These elbows have similar functions,the only difference is the 90 degree elbow can changes the direction in 90 deg while the 45 degree elbow can changes in 45deg.
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.
There are 45 ° elbows and 90 ° elbows in common use. Those with a bending radius of about 1.0 times the outer diameter of the pipe are called short radius elbows; The long radius elbow is about 1.5 times the outer diameter of the pipe
In the layout of the pipeline system, long radius elbows should generally be used for connection, and short radius elbows are usually used in places where the installation position of the pipeline system is compact or to reduce costs
Pipe elbows have three types:THD (threaded),SW (socket weld),BW (butt welded).These elbows used different connections to connect with the pipes in piping system.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel fittings can used over 50 years.
When short radius elbows are used, the maximum working pressure should not exceed 0.8 times of long radius elbows of the same specification Miter elbows are usually used for large-size pipes with moderate conditions in low pressure (design pressure s2.0mpa), water and similar fluid media
When the direction change angle of the single section of the miter elbow is greater than 45, it should not be used in the pipeline with toxic and combustible media, or in the pipeline subject to vibration, pressure pulsation and alternating load due to temperature change
BW 90 degree elbow is the most commonly used type of elbows.There is also 45 deg elbow.These elbows have similar functions,the only difference is the 90 degree elbow can changes the direction in 90 deg while the 45 degree elbow can changes in 45deg.You could find the steel pipe elbow specifications in the connent below.
Elbow is a commonly used connecting pipe fitting in plumbing installation, which is used for connecting pipe bends
Connect two pipes with the same or different nominal diameters to make the pipeline turn at 90 degrees, 45 degrees, 180 degrees and other angles
According to its radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow means that its radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, r = 1.5D. Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, r = 1.0d.
Equal butt weld elbow is used to change the direction of the flow in piping system.SCH 80 is a commonly used wall thickness for butt welded fittings,the other commonly used wall thickness is SCH 40.
Elbow is divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PPC, etc. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.
According to the production process, it can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.
Reducer can divided as concentric reducer and eccentric reducer.These reducer have same functions in pipe system,the only diffierence is the internal structure. Carbon steel fittings are used in many applications because of its great excellent functions.
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
The reducing tee has two outlets cut at 90 degrees with the main pipe, and the size of the branch pipe is smaller than the port of the pipeline. It is used for main pipe string accessories, solvent welding accessories, side outlet and conflicting soluble welding accessories
Steel pipe tee is a pipe fitting used to tansport the flow in the piping system.Carbon steel fittings are used in many applications becasue of its great excellent functions.
Equal diameter tee, also known as straight tee, the branch diameter of the tee is the same as the pipe diameter of the tee. The three branches of tee have same diameters.
Butt weld elbow is the most used type of elbows.It can welded with the pipes to achieve strong and permanent connection.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel fittings can used over 50 years.
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
Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbow
Stainless reducer is a butt welded pipe fitting used to reduce the flow in the pipe systems.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.
90 deg elbow is always used in piping systems.The other degree of elbows is 45 deg elbow.These elbows have similar functions,the only difference is the 90 degree elbow can changes the direction in 90 deg while the 45 degree elbow can changes in 45deg.A403 WP316L is a grade for stainless steel in American Standard.
Spiral wound gasket (SWG) is a fitting used with flanges.ASME B16.20 is the American Standard for gasket.
BW elbow is the most used elbows in all the type of elbows.There are types of elbows:BW (butt welded),SW (socket welded) and THD (threaded).Alloy steel pipe fittings are popular because the material is similar to carbon steel and its material can satisfy different demands.
Butt welded cap is a pipe fitting used to closed the piping systems.BW caps use welding connection to connect with the pipes.SCH 80 is a commonly used wall thickness of BW fittings,the other commonly used wall thickness is SCH 40.
The body of the branch abutment is made of high-quality forgings, which are made of the same materials as the pipes, including carbon steel, alloy steel, stainless steel, etc. The branch pipe seat and the main pipe are welded
Welded steel pipe is a type of steel pipes,the other type is seamless steel pipe (SMLS).Welded steel pipes also can divided into ERW,SSAW,LASW,DSAW.
Carbon steel pipes have a wide using range because it has great functions and affordable price.It can be welded pipe and seamless pipe,among these,the more used type is welded pipe.Welded pipes also have different types:LSAW pipe,SSAW pipe and ERW pipe.
