Common knowledge about flanges: General methods and steps for reading drawings.
Release time:
28 Jul,2022
In flange production work, it is necessary to frequently engage with various types of drawings, using views, section views, and profile drawings to represent the internal and external structures of the flange, as well as the contour dimensions and transitions of each part. Reading drawings is a basic requirement for employees in flange manufacturing companies.
In the flange production work, it is necessary to frequently refer to various drawings, using views, section views, and profile views to represent the internal and external structures of the flange; the contour dimensions and transitions of each part. Reading drawings is a basic requirement for employees in flange manufacturing.
General methods and steps for reading flange drawings:
(1) First, look at the title block to get a general understanding of the part.
Look at the title block to understand the part name, material, and scale, etc., thus gaining a general understanding of the part's function, determining the type of part from its name, inferring the approximate processing method from the material, and judging the actual size of the part from the scale to have a preliminary understanding of the part.
(2) Analyze and study the views, imagining the structural shape.
Look at the views, analyze the configuration of each view of the part and the relationships between the views, the expression methods used, and the content expressed. Use the reading methods of assemblies, shape analysis, and line-surface analysis to understand the structure of each part of the component, imagining the shape, relative position, and function of each part.
(3) Analyze all dimensions and clarify the dimensional requirements.
Comprehensively analyze the views and shapes, analyze the dimensional references in the three directions of length, width, and height of the part, then start from the references, using structural shape analysis as a clue, to understand the shaping and positioning dimensions of each shape, clarifying the role of each dimension. The graphics and dimensions express the shape and size of the part, and when reading the drawings, one should analyze the three aspects of views, dimensions, and shape structure together.
(4) Analyze technical requirements and comprehensively understand the entire drawing.
When reading the drawing, clarify the technical requirements such as surface roughness, dimensional tolerances, and geometric tolerances. Understand the meanings of their codes. If necessary, also analyze in conjunction with related parts.

RELATED INFORMATION
What types of flanges are used in the petrochemical industry?
In many applications, engineers need to find a way to safely close a chamber or cylinder, often because the composition or pressure of the internal material must be different from that of the external material.

What is the difference between butt welding fittings and socket fittings?
Butt welding connection is to fix the two parts completely after spot welding. Of course, the requirements for welders are also slightly higher, as butt welding needs to undergo 100% RT inspection under strict working conditions.

What aspects should be considered when using stainless steel flanges?
The stainless steel flange is a flange that connects steel pipes, fittings, etc. into the flange and connects to equipment or pipelines through corner welds. The inner hole on one side of the flange is equipped with a welded boss, which has an inner hole. The inner hole is connected to the inner hole at the center of the flange, and there is elasticity between the flange and the welded boss.

What types of flanges do we often use?
The main types of flanges are welding neck, long welding neck, lap joint, threaded, and blind flanges, as well as slip-on, socket weld. In addition to these standard flanges, there are also some special flanges, such as rotating flanges, expansion/reduction flanges, and hole flanges.
