Flanges Manufacturing Process?
The flange manufacturing process is mainly divided into three main aspects; forging, casting, cutting and rolling. Generally, the basic procedure involves machining the raw materials and then shaping them into the desired shape. The flange is then sealed and customized to the applicable standard before going to a consumer.
What are the raw materials used in flange manufacturing?
The manufacturing process of flange begins with the basic amenity; the raw materials, which are sourced from the first or second world’s developed countries. These raw materials undergo rigorous testing, specifically the Factory Test Report (MTR), which determines whether the material’s chemical and physical properties are intact and beneficial to meet a minimum required standard of use. The most common materials used for the manufacture of flanges are aluminium, stainless steel, ductile iron, and low carbon/carbon steel.
How are flanges manufactured?Initial steps:
- Step 1: Blanking
- Step 2: Machining
- Step 3: Drilling
- Step 4: Finishing
The initial manufacturing process of flanges includes blanking at first, and later machining, drilling and finishing in order to achieve the ideal specifications. Later, other processing like cutting, forging and casting can also be used for the production of flanges. Forged flanges are generally more wear-resistant but more expensive to produce. In comparison, cast flanges are less expensive to produce but can fail under high pressure.
Treatments for anti-rust capacities
In order to check the conventional anti-rust capacity, there are treatments of steel flanges which include yellow (gold) painting, varnish anti-rust oil coating, black painting or black phosphating treatment, hot-dip galvanized coating, varnish coating, electro galvanized (cold) coating, among others. For determining the smoothness or roughness of the flange, they are processed once the flange is casted, cut or forged. The type of flange finish varied, mainly depending on the application. They are commonly available in plain, machined, rolled and continuous or concentric teeth. After everything is complete, then the flanges are applied a protective coating before shipping the parts.
Summing it up
The final step in the process of manufacturing steel flanges is the packaging and dispatching of the products. These steel flanges must be taken extra care of and be packed in airworthy packaging conventions. The cases used for packaging generally include iron cages, iron pallets, wooden pallets, wooden cases, among others. The manufacturing procedures of flanges can greatly vary in terms of demand, applications and purpose. Based on that, one should opt for flanges meeting their requirements and having beneficial properties related to their concern of applications.
