10CrMo910 electrical marker elbow

Electric mark seamless hot - pressure elbow is often used in pipe bending to change the direction of the pipe. Commonly used are 45° elbows and 90° elbows. A short radius elbow whose bending radius is about 1.0 times the outer diameter of the pipe; A long radius elbow about 1.5 times the outside diameter of the pipe. In piping system layout, it is generally appropriate to use long radius elbow connection, short radius elbow is usually used in piping system installation position is more compact occasions or in order to reduce costs. When using a short radius elbow, the working pressure should not exceed 0.8 times of the same specification of a long radius elbow. Elbows are commonly used in large sized pipes with low pressure (design pressure s2.0mpa), water and similar fluids where conditions are relatively moderate. When the miter Angle is greater than 45, it is not suitable for the pipeline of toxic and combustible medium, or the pipeline which is subjected to vibration, pressure pulsation and alternating load due to temperature change. Product process standard and quality control: feeding -- physicochemical -- blanking -- hot forging forming -- heat treatment -- inspection -- gold processing -- finished product inspection -- marking -- finished product inspection -- packaging typing -- delivery.

Electric standard seamless hot pressure elbow suitable for gas, liquid, steam, is widely used in petroleum, chemical industry, electricity, construction, water conservancy and other large projects. The quality of the products conforms to the export and national product standard of high pressure pipe fitting.
