Butt weld elbows are bent by steel pipes. The function of butt weld elbows in a piping system is to change the direction. There are different angles, such as 45deg elbows, 90deg elbows, 180deg elbows. Other degrees elbows can be machined from a standard elbow. According to different bend radius, elbows are divided into long radius elbows and short radius elbows. The center to face distance for a "long" radius elbow, abbreviated LR always is "1½ x Nominal Pipe Size (NPS) (1½D)", while the center...
According to different facings, weld neck flange can be divided into raised face WN flange and flat face WN flange. It is circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. Size 1/8" NB TO 60"NB. Class 150#, 300#,400 #,600#,900#, 1500# & 2500 #.

Reducers are a kind of butt weld fittings that will be used for reducing piping size. In the piping system, they will be connected 2 pieces of pipes with different diameters. Main types are concentric and eccentric. Concentric reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area. a. Concentric reducer: have a central axis (centerline) of the section between the large and small. b. Eccentric reducer: the central axis has a different (offset)...
Compared with welded pipe, what is the strong point for seamless steel pipes? And what disadvantage do weld pipes have? 1.The greatest advantage of seamless steel pipes is their increased ability to withstand pressure. The weakest point in a welded steel pipe is the welded seam. But because a seamless steel pipe has not been welded, it doesn’t have that seam, making it equally strong around the entire circumference of the pipe. 2.Because welded pipe is wrapped around another form before it is...
Steel pipes are made by two different types, including seamless steel pipes and welded pipes. The manufacturing process of steel pipes involves three steps, First, raw steel is converted into a more workable form. Second, the pipe is formed on a continuous or semicontinuous production line. Finally, the pipe is cut and modified to meet the customer's requirements. Steel pipes can be seen in a variety of places. Since they are strong, they are used underground for transporting water and gas...
Socket weld fittings belong to forged fittings whose pressure is very high, such as 3000LB,6000LB,9000LB. Normally the size for SW fittings are very small. For different type of pipe fittings, socket weld fittings include socket weld elbows, socket weld tees, socket weld crosses. If under the same size, the prices for socket weld fittings are much higher than butt weld fittings.

Everyone knows concentric reducer is also a kind of butt weld pipe fittings. Besides concentric type, there are eccentric reducers. The difference is that if the center is on the same line. Concentric reducers are used in piping systems to connect pipes of two different outside diameters. Both concentric reducers and eccentric reducers decrease the effective size of the pipe. With smaller crosssectional area there is increased frictional resistance to the flowing material and an increase system...

What's the difference between ANSI B16.5 flange & ASME B16.5 flange? The answer is there is no difference. First of all, ANSI B16.5 standard was published in 1973. In 1996 the standard changed to ASME B16.5. For 10 years prior to the change, the standard included both and was listed as ANSI/ASME B16.5. The current and correct standard is ASME B16.5. ANSI B16.5 is common industry lingo and is still referred to extensively by architects, engineers, manufacturers and suppliers. And although...

Available Standards with these forged flanges are as follows: ANSI B16.5, ANSI B16.47, MSS...
According to the radius of curvature, carbon steel elbows are divided into long radius(LR) elbows and short radius(SR) elbows. The long-radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the tube, ie R = 1.5D. A short-radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = 1.0D. (D means the outside diameter, R is the radius of curvature. D can also be expressed in multiples.) Carbon steel elbows are divided...

For stainless steel welded pipes, there are some reasons for corrosion. Pls check below for them First, from the corrosion site 1. Pitting corrosion: It is a form of local corrosion that causes corrosion. 2. Intergranular corrosion: The grain boundary is a boundary between crystal grains with different crystallographic orientations. Therefore, they are segregation of various solute elements in steel or precipitation of metal compounds (such as carbides and δ phases). Favorable district city....
