Blanking standard for seamless elbows

As a kind of pipe connector, seamless elbow is widely used in the pipeline system of petroleum, chemical industry, electric power, metallurgy and other industries. Its production process is a complex project, need to go through the design, blanking, processing, welding and other links. Among them, cutting as a step in the production of seamless elbows is a crucial link. In the blanking of seamless elbows, certain standards and specifications need to be followed to ensure the accuracy and efficiency of the blanking work.

First of all, the blanking of the seamless elbow needs to be carried out according to its design drawings. The design drawing includes key parameters such as the diameter, Angle and length of the elbow. The cutting personnel need to read the drawing carefully and determine the cutting size according to the size requirements on the drawing.

Secondly, after determining the cutting size, the cutting personnel need to choose the appropriate cutting tools and equipment. Commonly used blanking tools include cutting machines, CNC cutting machines, manual cutting tools, etc. When selecting the blanking tool, it is necessary to take into account the material, thickness and length of the elbow to ensure the smooth progress of the blanking work.

Next, the cutting personnel need to place the raw material of the elbow on the cutting tool and cut it according to the size requirements on the design drawing. When cutting, pay attention to keep the incision flat and vertical to avoid deviation and error.
