UOE is a method used for production of longitudinally welded large diameter pipes. Longitudinal edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press. In accordance with different requirements of the customers, the welded pipe can be expanded either by mechanical or hydrostatic expander to improve dimensional accuracy, and eliminate residual stress. Steel Pipe can...

Product Introduction Welded pipe is an electric welded round pipe that is an alternative to steel pipes.It is a structural grade tube that is suitable for a wide variety of applications where dimensional accuracy and precision tolerances is not a primary concern.A raised weld seam is present inside the pipe. Spiral welded steel pipe is a kind of practical steel pipe, now it has been widely used in small and medium-sized construction site construction facilities, not only that, spiral steel pipe...

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. Steel Pipe can be divided into Cold Drawn Smls Steel Pipe Hot Rolled Smls Steel Pipe Galvanized Steel Pipe. Features of ERW pipe Low cost: the low raw material cost and manufacturing cost make it prices more competitive than longitudinal seam submerged-arc welded pipes and seamless pipes. High Weld Seam Security: As a result of...

These Flanges are used as a termination point to a piping system. Blind-Flanges have a blank surface with bolt point to fit a pipe. Flange JPI Class 150 BL RF A20 B3 Pipe Flanges And Fittings The blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange...

Slip-On flange also exists as a reduction where a larger slip-on flange blank is cut out to accommodate a smaller connection size. The slip-on reducing flange is used when reducing the line size in areas where there are space limitations. Advantages of slip on flanges: Slip-On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers. Low cost installation Pipe Flanges And Fittings Less time needed to spent on ensuring...

Lap Joint Flanges (LJ Flanges) are used on piping fitted with lapped pipe or with lap joint stub ends the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges. Furthermore, a standard lap joint flange will typically have a longer hub length in comparison to a slip on flange, but this is often considered unnecessary for many applications. Pipe Flanges And Fittings Ceramic Lined Lateral pipe Wye Ceramic Lined Lateral pipe Wye...

Galvanized Steel Pipe Galvanized steel pipe is a kind of carbon steel pipe, mostly welded pipe，Galvanized steel pipes are divided into cold galvanized steel pipes (electro galvanized steel pipes) and hot-dip galvanized steel pipes. At present, hot-dip galvanized steel pipes are mainly used in fire protection, electric power and highways. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as...

Weld-Neck flanges or welding-neck flanges can be differentiated from all other types of flange by their long tapered hub. Welded pipe Expander Flange is a Welding Neck pipe flange where the nominal size of the non-flanged end is larger than the nominal size of the flanged end. They can be used to change the size of a pipe run. These are usually used to increase the line size to the first or second larger size. This is an alternative to using a separate reducer and weld neck flange combination....
