Product Description

       English (Welded butt welding elbow here) are steel hot-pressing molding or bend forging forming, its connection form is directly to the elbow and the steel pipe butt welding, butt welding elbow's main manufacturing standards are generally GB/T13401-2005, GB/T12459-2005, ASME B16.9, SH3409, HG/T21635, HG/T21631, SY/T0510, GB/T10752-1995.

    The alloy elbow made of manganese steel is usually used in concrete conveying pipeline and mud conveying pipeline because of its excellent performance of bearing impact, extrusion and material wear.And the high manganese steel alloy elbow is used in the fluid flow is more intense, strong impact pipeline;Nickel-steel alloy elbow is usually used in high-concentration oxidized acid (nitric acid, sulfuric acid) in the room temperature pipeline, but in reductive acid (hydrochloric acid, dilute sulfuric acid, etc.) in the pipeline will be severely corrosive, unless the concentration of hydrochloric acid is very low;Martensitic alloy bend under 650 ℃ high temperature strength, oxidation resistance and water vapor corrosion resistant ability, but poor weldability.Therefore, is often used in the high temperature steam pipeline, water gas pipeline.Executive standards :GB/ t12459-2005, GB/T13401, GB/ t10752-1999


The butt welding elbow classification


(1) the butt welding elbow press its radius of curvature to points, can be divided into the butt welding elbow butt welding elbow long radius and short radius.Long radius butt weld bend radius of curvature is equal to 1.5 times the pipe diameter, R = 1.5 D.Short radius butt weld bend radius of curvature is equal to the pipe diameter, R = 1 d.Type D for butt welding of bend diameter, R is the radius of curvature.If no specific instructions, general selection is 1.5 D bend.


If (2) according to the grades of pressure points, about seventeen, and American standard pipe is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, Sch100, Sch120, Sch140, Sch160, XXS, one of the most common is two kinds of STD and XS.


(3) according to bend Angle points, butt welding elbow has 45 degrees, 90 degrees 90 degrees of butt welding elbow and butt welding elbow bend and other different angles.


(4) material: carbon steel, alloy steel and stainless steel.
