Seamless steel pipe used as a large number of transmission fluid pipelines, such as the transportation of oil, natural gas, gas, water and some solid materials such as pipes. Steel pipe is also widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, car drive shaft, bicycle frames and steel construction...

180 elbow belongs to a seamless elbow pipe elbow, which refers to the degree of bend of 180 degrees. The shape of the bend is a 180 degree semicircle. It belongs to the category of the bend. Depending on the needs of the project can be produced R is 1.5D, 3D, 4D, 5D even larger bend radius. Seamless elbow 180 degrees ...

45 degree elbow and 90 ° elbow ,  90 degree elbow forming a right angle and 45 degrees is an obtuse angle. Seamless elbow 45 degrees Nominal Diameter  Outside Diameter  at Bevel  Center to End...

Then bend the production process. To elbow, for example, if the long radius of elbow, such as the use of steel push system, the first selection of specifications, the pipe material. Expansion rate, through theoretical calculations, the general expansion rate of 33% -35% between the back to push back. The general radius of 219mm diameter...

A234 WPB material is currently the most commonly used in the world for high temperature carbon steel pipe material, the source can be steel pipe, such as ASTM A106 Gr.C, can also be steel, such as ASTM A285 GR.C. ASTM A234 GR.WPB Chemical composition and performance index (standard value) Wt% ≤0.30, Si (Wt%) ≥0.10, Mn (Wt%) 0.29-1.06, P...

Elbow by its radius of curvature to points, can be divided into long radius elbow and short radius elbow. A long-radius elbow refers to a tube having a radius of curvature equal to 1.5 times the outer diameter of the tube, i.e. R = 1.5D. A short-radius elbow means that its radius of curvature is equal to the outside diameter of the tube, ie, R...

Weld Elbow materials used for steel manufacturing steps with two longitudinal weld elbow is first on the steel sheet lofting, cutting two similar web-shaped, depending on the material is determined directly after the cold still need heating hot and then the sheet material into a mold by pressing the upper and lower mold clamping half weld...

Seamless carbon steel elbow seamless steel pipe is pushed into the heating type. Pipe elbow is to change the direction of the pipe in the piping system. 45 ° and 90 ° 180 ° three kind most commonly used, according to project needs, also include 60 °bend and other non-normal angles. Elbow Specifications ...

SWelded Carbon Steel pipe traight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the pipe with larger diameter can be produced with the narrow billet. The pipe with different...

Erw Structural Steel Pipe ERW steel pipe detection means: In addition to the corresponding standard requirements must have the geometric size, physical and chemical properties, pressure (pressure) test, non-destructive testing and other tests, tests, but also the need for appropriate physical and chemical testing. Erw Steel...
